HUANENG GROUP FRAMEWORK AGREEMENT

The Company entered into the 2021 Huaneng Group Framework Agreement with Huaneng Group on 5 November 2020 and the Supplemental Agreement to Huaneng Group Framework Agreement on 28 September 2021 for the purpose of governing the conduct of certain continuing connected transactions between the Company and Huaneng Group (and its subsidiaries and associates) in 2021. The relevant agreements will expire on 31 December 2021. In order to continue the relevant transactions, the Company entered into the Huaneng Group Framework Agreement with Huaneng Group on 3 November 2021 for a term commencing on 1 January 2022 and expiring on 31 December 2022.

Pursuant to the Huaneng Group Framework Agreement, the Company and its subsidiaries will conduct the following transactions with Huaneng Group and its subsidiaries and associates on an on- going basis:

(1) Purchase of ancillary equipment and parts

Due to operational needs, the Company and its subsidiaries have to purchase ancillary equipment and parts which include mainly the raw materials and ancillary equipment and other installation and products relevant to the production operation for the infrastructure construction works for power plants. Pursuant to the provisions of the 2021 Huaneng Group Framework Agreement with respect to the purchase of ancillary equipment and parts in 2021 by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates, the annual cap of such transactions for 2021 was set at RMB2 billion. During the period from 1 January 2021 to 30 September 2021, the aggregate transaction amount (unaudited) in respect of the purchase of ancillary equipment and parts by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates was approximately RMB607 million. It is estimated that by the end of 2021, the actual aggregate transaction amount will not exceed the anticipated transaction amount of 2021.

- 3 -

For 2022, the aggregate transaction amount with respect to the purchase of ancillary equipment and parts by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates under the Huaneng Group Framework Agreement is estimated not to exceed RMB2.1 billion. Such cap is estimated on the basis of the overall business scale and operation of the power plants of the Company and its subsidiaries, a reasonable expectation of the Company and its subsidiaries as to the development of the relevant power plants, and also taking into account at the same time the benefit of offering favourable prices on bulk purchases by Huaneng Group and its subsidiaries and associates.

The competitive advantage of Huaneng Group and its subsidiaries and associates in the supply of ancillary equipment and parts is that they are able to offer more favourable prices for bulk purchase of ancillary equipment and parts. Taking into consideration the ability of Huaneng Group and its subsidiaries and associates to offer more favourable prices for ancillary equipment and parts, and owing to their close relationships with the Company and its subsidiaries, Huaneng Group and its subsidiaries and associates are able to provide the Company with the ancillary equipment and parts in a timely and reliable manner, thereby minimising the management and operational costs of the Company.

Pursuant to the Huaneng Group Framework Agreement, the terms and the prices with respect to the purchase of ancillary equipment and parts by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates are negotiated at arm's length terms, taking into account the then prevailing market conditions; but in any event at the terms and prices no less favourable than those offered to the Company and its subsidiaries by an independent third party for the same or similar type of ancillary equipment and parts. In addition, the payment of such purchases will be settled in cash in arrears, or in accordance with the payment terms agreed by the relevant parties in the contracts to be entered into pursuant to such framework agreement.

The Board (including the independent non-executive Directors) is of the view that the transactions for the purchase of ancillary equipment and parts as contemplated by the Huaneng Group Framework Agreement were entered into: (i) in the ordinary and usual course of business of the Company; (ii) on normal commercial terms (on arm's length basis or on terms no less favourable to the Company than terms available from independent third parties); and (iii) on terms and proposed cap that are fair and reasonable and in the interest of the Company and its shareholders as a whole.

As none of the applicable percentage ratios relating to the scale of the transactions in question calculated in accordance with Rule 14.07 of the Hong Kong Listing Rules exceeds 5%, such transactions are only subject to the reporting and announcement requirements under Rules 14A.71 and 14A.35 of the Hong Kong Listing Rules but are exempt from the Independent Shareholders' approval requirements. In addition, the Company will, with respect to the transactions in question, comply with the requirements under Rules 14A.55 to 14A.59 of the Hong Kong Listing Rules in respect of the annual review of these continuing connected transactions. If the actual aggregate amount of such transactions during the year ending 31 December 2022 exceeds the above cap (i.e. RMB2.1 billion), the Company will further comply with the requirements under Rule 14A.54 of the Hong Kong Listing Rules.

- 4 -

(2) Purchase of fuel and transportation services

The Company's main fuel for power generation is coal. Pursuant to the Huaneng Group Framework Agreement, the Company and its subsidiaries will purchase fuel and coal transportation services from Huaneng Group and its subsidiaries and associates at prices and charges calculated by reference to RMB/ton and the actual weight of carriage, with arm's length terms taking into account the then market conditions, and in any event the terms of the purchases of fuel and the transportation services shall be no less favourable than those offered by independent third parties to the Company and its subsidiaries for the same or similar type of fuel supply or transportation services.

Pursuant to the provisions of the 2021 Huaneng Group Framework Agreement and the Supplemental Agreement to Huaneng Group Framework Agreement with respect to the purchase of fuel and transportation services in 2021 by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates, the cap of the aggregate transaction amount for 2021 was revised at RMB85 billion. During the period from 1 January 2021 to 30 September 2021, the aggregate transaction amount (unaudited) for purchase of fuel and transportation services by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates was approximately RMB43.717 billion. It is estimated that by the end of 2021, the actual aggregate transaction amount will not exceed the anticipated transaction amount (as revised) of 2021.

The cap of the transaction amount for purchase of fuel and transportation services by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates pursuant to the Huaneng Group Framework Agreement in 2022 is estimated to be RMB120 billion. The payment of the consideration will be settled in cash in arrears, or in accordance with the payment terms agreed by the relevant parties in the contracts to be entered into pursuant to the framework agreement. The cap of such amount is set based on the current overall business scale and operation of the Company and the power plants of its subsidiaries, and the reasonable expectation of those power plants by the Company and its subsidiaries, and at the same time the capability in offering relatively competitive prices on bulk purchase by scale purchase of fuel and transportation by Huaneng Group and its subsidiaries and associates.

The competitive advantage of Huaneng Group and its subsidiaries and associates in the supply of fuel and transportation services is that they can offer more favourable prices for bulk purchase of fuel and transportation services. Taking into consideration the ability of Huaneng Group and its subsidiaries and associates to offer more favourable prices for purchases of fuel and transportation services, and owing to their close relationships with the Company and its subsidiaries, Huaneng Group and its subsidiaries and associates are able to provide the Company and its subsidiaries with fuel and transportation services in a timely and reliable manner, thereby minimising the management and operational costs of the Company and its subsidiaries.

- 5 -

The reasons for the increase in the estimated transaction amount for 2022 are :- in 2021, there have been significant increases in coal prices and transportation charges. It is expected that in 2022 the coal prices will continue to fluctuate at high level and the transportation capacity will continue to be tight. In order to ensure the Company's stable supply of fuel throughout the year, the amount of the purchase of fuel and transportation in 2022 by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates will increase correspondingly, so as to take full advantage of the ability of Huaneng Group and its subsidiaries and associates to provide favourable prices for coal and transportation capacity purchases and for safe and secure supply.

The Company has a right in procurement selection. Huaneng Group and its subsidiaries and associates will participate in the Company's procurement auction, the Company shall make use of the scale procurement advantage of Huaneng Group and its subsidiaries and associates to obtain prices which shall be no less favourable than the prices from independent third parties offered to the Company and its subsidiaries.

The Board is of the view that the transactions for the purchase of fuel and transportation services from Huaneng Group and its subsidiaries and associates contemplated under the Huaneng Group Framework Agreement were entered into: (i) in the ordinary and usual course of business of the Company; (ii) on normal commercial terms (on arm's length basis or on terms no less favourable to the Company than terms available from independent third parties); and (iii) on terms and proposed caps that are fair and reasonable and in the interest of the Company and its shareholders as a whole.

As the applicable percentage ratios relating to the transaction scale for the purchase of fuel and transportation services by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates calculated in accordance with Rule 14.07 of the Hong Kong Listing Rules exceed 5%, such transactions shall be subject to the reporting and announcement requirements under Rules 14A.71 and 14A.35 of the Hong Kong Listing Rules and the requirement to obtain approval from the Independent Shareholders. The Company has conducted a detailed survey in respect of its short-term and long-term operational demand for coal and coal transportation services. The Company is of the view that before the convening of the extraordinary general meeting, such transactions will not (and the Company will through its internal control system ensure that such transactions will not) exceed the relevant thresholds that require Independent Shareholders' approval under the Hong Kong Listing Rules.

(3) Leasing of facilities, land and office spaces

For operational needs, the Company and its subsidiaries have to lease facilities, land and office spaces (mainly including power transmission and transformation assets, vessels, land and office spaces for power plants, etc.) from Huaneng Group and its subsidiaries and associates. Pursuant to the provisions of the 2021 Huaneng Group Framework Agreement with respect to the leasing of facilities, land and office spaces in 2021 by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates, the cap of the relevant transaction amount for 2021 was set at RMB300 million. During the period from 1 January 2021 to 30 September 2021, the aggregate transaction amount (unaudited) which has already been paid by the Company and its subsidiaries to Huaneng Group and its subsidiaries and associates for leasing of facilities, land and office spaces was approximately RMB108 million. It is estimated that by the end of 2021, the actual aggregate transaction amount will not exceed the anticipated transaction amount of 2021.

Pursuant to the Huaneng Group Framework Agreement, the transaction amount with respect to the leasing of facilities, land and office spaces by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates in 2022 is estimated not to exceed RMB300 million. The estimate of such cap amount is based on the existing overall business scale and operation of the power plants of the Company and its subsidiaries, the anticipated development and growth of such power plants as deemed reasonable by the Company and its subsidiaries, taking into account at the same time the benefit of favourable prices offered by Huaneng Group and its subsidiaries and associates for leasing of facilities, land and office spaces.

In respect of leasing of facilities, land and office spaces, the competitive advantage of Huaneng Group and its subsidiaries and its associates is their ability to offer more favourable prices for leasing of facilities, land and office spaces. Taking into consideration the ability of Huaneng Group and its subsidiaries and associate in offering more favourable prices for leasing of facilities, land and office spaces, and owing to their close relationships with the Company and its subsidiaries, Huaneng Group and its subsidiaries and associates are able to provide the Company with the leased facilities, land and office spaces in a timely and reliable manner, thereby minimising the management and operational costs of the Company and its subsidiaries.

Pursuant to the Huaneng Group Framework Agreement, the terms and the prices with respect to the leasing of facilities, land and office spaces to the Company and its subsidiaries by Huaneng Group and its subsidiaries and associates are negotiated at arm's length terms, taking into account the then prevailing market conditions; but in any event at the leasing terms and prices no less favourable than those offered to the Company and its subsidiaries by independent third parties for the same or similar types of leased facilities, land and office spaces. In addition, the payment will be settled in cash, or in accordance with the payment terms agreed by the relevant parties in the contracts to be entered into in future pursuant to the framework agreement.

The Board (including the independent non-executive Directors) is of the view that the transactions for the leasing of facilities, land and office spaces contemplated under the Huaneng Group Framework Agreement were entered into: (i) in the ordinary and usual course of business of the Company; (ii) on normal commercial terms (on arm's length basis or on terms no less favourable to the Company than terms available from independent third parties); and (iii) on terms and proposed caps that are fair and reasonable and in the interest of the Company and its shareholders as a whole.

As none of the applicable percentage ratios relating to the scale of the transactions in question calculated in accordance with Rule 14.07 of the Hong Kong Listing Rules exceeds 5%, such transactions are only subject to the reporting and announcement requirements under Rules 14A.71 and 14A.35 of the Hong Kong Listing Rules but are exempt from the Independent Shareholders' approval requirements. In addition, the Company will, with respect to the transactions in question, comply with the requirements under Rule 14A.55 to 14A.59 of the Hong Kong Listing Rules in respect of conducting annual reviews of these continuing connected transactions. If the actual aggregate amount of such transactions during the year ending 31 December 2022 exceeds the above cap (i.e. RMB300 million), the Company will further comply with the requirements under Rule 14A.54 of the Hong Kong Listing Rules.

(4) Technical services, engineering contracting services and other services

The reciprocal technical services, engineering contracting services and other services between the Company and its subsidiaries and Huaneng Group and its subsidiaries and associates mainly include the provision of fuel management service relevant to power plants, maintenance services for power plants' monitoring systems, real-time consolidation of project data, trial run of generating units, supervision of manufacture of facilities for construction works in progress and insurance services by Huaneng Group and its subsidiaries and associates to the Company and its subsidiaries. At the same time, the Company and its subsidiaries provide operation/production related services to Huaneng Group and its subsidiaries and associates. Pursuant to the 2021 Huaneng Group Framework Agreement, the cap for the aggregate transaction amount with respect to the purchase of technical services, engineering contracting services and other services by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates for 2021 and the provision of operation/production and related services from the Company and its subsidiaries to Huaneng Group and its subsidiaries and associate for 2021 were set at RMB2.9 billion. During the period from 1 January 2021 to 30 September 2021, the aggregate transaction amount (unaudited) between the Company and its subsidiaries and Huaneng Group and its subsidiaries and associates was approximately RMB1.516 billion. It is estimated that by the end of 2021, the actual aggregate transaction amount will not exceed the anticipated transaction amount of 2021. The substantial difference between the estimated transaction amount and the actual transaction amount was primarily due to the fact that adjustments were made to the projected transactions based on the Company's actual business scale and operation as a whole and the changes in market conditions.

- 8 -

Pursuant to the Huaneng Group Framework Agreement and the adjustments made based on the Company's actual overall business scale and operations, the market changes and the expected volume of transactions, the transaction amount with respect to technical services, engineering contracting services and other services between the Company and its subsidiaries and Huaneng Group and its subsidiaries and associates in 2022 is estimated not to exceed RMB4.2 billion. The estimate of such cap is based on the one hand on the existing overall business scale and operation of the power plants of the Company and its subsidiaries as well as the anticipated development and growth of such power plants as deemed reasonable by the Company and its subsidiaries, having taken into account the benefit of favourable prices for the purchase of technical services and engineering contracting services and other services offered by Huaneng Group and its subsidiaries and associates, and on the other the needs of providing services in relevant business operation by the Company and its subsidiaries to Huaneng Group and its subsidiaries and associates. With the continuous enhancement and improvement of the technical strength of the information company of the Company, in addition to the Company's internal information construction and operation and maintenance work, the Company and its subsidiaries have gradually begun to undertake the information operation and maintenance service for Huaneng Group and its subsidiaries and associates.

On the one hand, the competitive advantage of Huaneng Group and its subsidiaries and associates in terms of providing technical services, engineering contracting services and other services is that they can offer more favourable prices to the Company and its subsidiaries. Taking into consideration the ability of Huaneng Group and its subsidiaries and associates to offer more favourable prices for technical services, engineering contracting services and other services, and owing to their close relationships with the Company and its subsidiaries, Huaneng Group and its subsidiaries and associates are able to provide the Company and its subsidiaries with the technical services, engineering contracting services and other services in a timely and reliable manner, thereby minimising the management and operational costs of the Company and its subsidiaries. In addition, some of the subsidiaries and associates of Huaneng Group focus on researching information technology and national new energy power generation technology, as well as equipment of thermal energy in power plants, therefore can provide reliable and efficient services of information technology and project contracting, and can also provide advanced and comprehensive power station-specific technical services and project contracting services, which can lower the operational costs of the Company and its subsidiaries. On the other hand, the Company is of the view that the provision of relevant production and operation services to Huaneng Group and its subsidiaries and associates can bring operational benefits to the Company and its subsidiaries.

Pursuant to the Huaneng Group Framework Agreement, the terms and the prices of transactions with respect to technical services, engineering contracting services and other services between the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates are negotiated at arm's length terms, taking into account the then prevailing market conditions; but in any event at the terms and prices no less favourable than those offered to the Company and its subsidiaries by independent third parties for the same or similar types of technical services, engineering contracting services and other services. In addition, the payment of consideration will be settled in cash in arrears, or in accordance with the payment terms agreed by the relevant parties in the contracts to be entered into pursuant to the framework agreement.

- 9 -

The Board (including the independent non-executive Directors) is of the view that the transactions with respect to technical services, engineering contracting services and other services as contemplated under the Huaneng Group Framework Agreement were entered into: (i)in the ordinary and usual course of business of the Company; (ii) on normal commercial terms (on arm's length basis or on terms no less favourable to the Company than terms available from independent third parties); and (iii) on terms and proposed caps that are fair and reasonable and in the interest of the Company and its shareholders as a whole.

As none of the applicable percentage ratios relating to the scale of the transactions in question calculated in accordance with Rule 14.07 of the Hong Kong Listing Rules exceeds 5%, such transactions are only subject to the reporting and announcement requirements under Rules 14A.71 and 14A.35 of the Hong Kong Listing Rules but are exempt from the Independent Shareholders' approval requirements. In addition, the Company will, with respect to the transactions in question, comply with the requirements under Rule 14A.55 to 14A.59 of the Hong Kong Listing Rules in respect of conducting annual reviews of these continuing connected transactions. If the actual aggregate amount of such transactions during the year ending 31 December 2022 exceeds the above cap (i.e. RMB4.2 billion), the Company will further comply with the requirements under Rule 14A.54 of the Hong Kong Listing Rules.

(5) Accept the provision of entrusted sale services from Huaneng Group and its subsidiaries and associates

The provision of entrusted sale services from Huaneng Group and its subsidiaries and associates to the Company and its subsidiaries involves mainly the use of power generation quota of Huaneng Group and its subsidiaries and associates for substituted power generation by the Company and its subsidiaries. Where the Company and its subsidiaries generate electricity under the quota of and in substitution for Huaneng Group and its subsidiaries and associates, payments under such transactions will be settled in two ways: (1) upon power generation, the Company and its subsidiaries shall settle the payment with the power grid company before paying the difference to Huaneng Group and its subsidiaries and associates; and (2) upon power generation, Huaneng Group and its subsidiaries and associates shall settle the payment with the power grid company before paying substituted power generation costs and other relevant expenses to the Company and its subsidiaries. Pursuant to the 2021 Huaneng Group Framework Agreement with respect to the acceptance for provision of entrusted sale services from Huaneng Group and its subsidiaries and associates to the Company and its subsidiaries, the cap of the aggregate transaction amount for 2021 was set at RMB700 million. During the period from 1 January 2021 to 30 September 2021, the aggregate transaction amount for the provision of entrusted sale services from Huaneng Group and its subsidiaries and associates to the Company and its subsidiaries was RMB0. It is estimated that by end of 2021, the aggregate of the actual transaction amount will not exceed the anticipated transaction amount in 2021. The reason for the substantial difference between the estimated transaction amount and the actual transaction amount was due to the adjustments made by the Company based on the actual overall business scale and operation status and the changes in market.

- 10 -

Pursuant to the Huaneng Group Framework Agreement, the transaction amount with respect to such entrusted sale services between the Company and its subsidiaries and Huaneng Group and its subsidiaries and associates for 2022 is estimated to be RMB400 million. Such cap is set on the basis of the current overall business and operation scale of the transaction parties, estimation of the on-grid tariff and substitution tariff, and reasonable expectation of the Company and its subsidiaries as to the development of the transaction parties. The on-grid tariff and substitution tariff are determined by the then prevailing market price. With the generation quota, whether it is acquired from connected persons or independent third parties, the Company can increase its production capacity and the effect of which can bring about higher marginal contribution to the Company.

In order to increase electricity output and boost efficiency, the Company and its subsidiaries have entered into substituted power generation transactions with power plants already closed or still in operation in the places where they are located (including connected persons and non- connected persons). The advantage of Huaneng Group and its subsidiaries and associates in the provision of substituted power generation is that they charge higher tariffs so that the Company and its subsidiaries can produce a higher marginal contribution. Besides, Huaneng Group and its subsidiaries and associates maintain good relationship with the Company and its subsidiaries.

Pursuant to the Huaneng Group Framework Agreement, the terms and prices with respect to the provision of aforesaid entrusted sale services from Huaneng Group and its subsidiaries and associates to the Company and its subsidiaries are negotiated at arm's length terms, taking into account the then prevailing market conditions, but in any event at the terms and prices no less favourable than those offered to the Company and its subsidiaries by an independent third party for the same or similar type of services.

The Board (including the independent non-executive Directors) is of the view that the transactions for provision of entrusted sale services from Huaneng Group and its subsidiaries and associates to the Company and its subsidiaries pursuant to the Huaneng Group Framework Agreement were entered into: (i) in the ordinary and usual course of business of the Company; (ii) on normal commercial terms (on arm's length basis or on terms no less favourable than terms accepted by the Company from independent third parties); and (iii) on terms and proposed caps that are fair and reasonable and in the interest of the Company and its shareholders as a whole.

As none of the applicable percentage ratios relating to the scale of the transactions in question calculated in accordance with Rule 14.07 of the Hong Kong Listing Rules exceeds 5%, such transactions are only subject to the reporting and announcement requirements under Rules 14A.71 and 14A.35 of the Hong Kong Listing Rules but are exempt from the Independent Shareholders' approval requirements. In addition, the Company will, with respect to the transactions in question, comply with the requirements under Rule 14A.55 to 14A.59 of the Hong Kong Listing Rules in respect of the annual review of these continuing connected transactions. If the actual aggregate amount of such transactions during the year ending 31 December 2022 exceeds the above cap (i.e. RMB400 million), the Company will further comply with the requirements under Rule 14A.54 of the Hong Kong Listing Rules.

(6) Sale of products

To be more cost-efficient in management, the Company's subsidiary(ies) will sell products (mainly coal) to Huaneng Group and its subsidiaries and associates. The sale transaction under this category is not a main business of the Company and its subsidiaries. The sale related to only the excess coal and therefore will take place only on condition that the Company's own power plants are preserved with sufficient coal supply for operation. The prices and charges of coal will be calculated by reference to RMB/ton and the actual weight of carriage, with arm's length terms taking into account the then market conditions, and in any event the terms of the purchases of coal and other related products shall be no less favourable than those offered by independent third parties to the Company for the same or similar type of coal supply and other related products. The Company will, through the information collection channels mentioned in transaction regarding purchase of fuel and coal transportation services in section headed "Measures to safeguard the interest of the Independent Shareholders" below, and with reference to the then market conditions and in conjunction with the costs for coal purchase by the fuel company, determine the then selling prices, so as to recoup the costs and to have a small profit. Pursuant to the 2021 Huaneng Group Framework Agreement, the cap of the aggregate transaction amount with respect to the sale of products by the Company and its subsidiaries to Huaneng Group and its subsidiaries and associates for 2021 was set at RMB500 million. During the period from 1 January 2021 to 30 September 2021, the aggregate transaction amount (unaudited) for the sale of products by the Company and its subsidiaries to Huaneng Group and its subsidiaries and associates was RMB11 million. It is estimated that by the end of 2021, the actual aggregate transaction amount will not exceed the anticipated transaction amount for 2021. The substantial difference between the estimated transaction amount and the actual transaction amount was primarily due to the fact that the Company has adjusted the transaction based on changes in the demand for coal from certain power plants of Huaneng Group and its subsidiaries.

Pursuant to the Huaneng Group Framework Agreement, the transaction amount with respect to the sale of products between the Company and Huaneng Group and its subsidiaries and associates for 2022 is estimated to be RMB500 million. The payment of the consideration will be settled in cash in arrears, or in accordance with the payment terms to be agreed by the relevant parties pursuant to the Huaneng Group Framework Agreement. Such estimate of cap amount is based on the demand of coal and relevant products of the power plants of Huaneng Group and its subsidiaries in 2022 and more favorable pricing by way of bulk purchase. In order to leverage the advantage of scale procurement, the Company may increase the purchase volume of coal and re-sell excess portion to the power plants of Huaneng Group and its subsidiaries.

- 12 -

The Board (including the independent non-executive Directors) is of the view that the transactions for sale of products to Huaneng Group and its subsidiaries and associates pursuant to the Huaneng Group Framework Agreement were entered into: (i) in the ordinary and usual course of business of the Company; (ii) on normal commercial terms (on arm's length basis or on terms no less favourable to the Company than terms available from independent third parties); and (iii) on terms and proposed caps that are fair and reasonable and in the interest of the Company and its shareholders as a whole.

As none of the applicable percentage ratios relating to the scale of the transactions in question calculated in accordance with Rule 14.07 of the Hong Kong Listing Rules exceeds 5%, such transactions are only subject to the reporting and announcement requirements under Rules 14A.71 and 14A.35 of the Hong Kong Listing Rules but are exempt from the Independent Shareholders' approval requirements. In addition, the Company will, with respect to the transactions in question, comply with the requirements under Rule 14A.55 to 14A.59 of the Hong Kong Listing Rules in respect of the annual review of these continuing connected transactions. If the actual aggregate amount of such transactions during the year ending 31 December 2022 exceeds the above cap (i.e. RMB500 million), the Company will further comply with the requirements under Rule 14A.54 of the Hong Kong Listing Rules.

(7) Purchase of electricity

The electricity purchase by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates is mainly attributable to the demand for participation in the electricity market transactions by local government(s) and electricity trading centres organised in their respective regions. Pursuant to the provisions of the 2021 Huaneng Group Framework Agreement with respect to the purchase of electricity by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates, the cap of the aggregate transaction amount for 2021 was set at RMB200 million. During the period from 1 January 2021 to 30 September 2021, the transaction amount (unaudited) in respect of the purchase of electricity by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates was RMB0.

For 2022 and based on the adjustments made due to the market changes brought about by adjustments in industry policy and the Company's actual operating conditions, the transaction amount with respect to purchase of electricity by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates is estimated to be RMB3.6 billion. According to the latest adjustment to industry policy, more commercial and industrial customers will participate in market-based electricity trading in 2022. Meanwhile, according to the latest pricing policy for electricity, high coal prices will correspondingly push up the level of electricity trading prices. Therefore, it is expected that the transaction amount of electricity purchase between the Company's subordinate electricity sales companies and the power plants of Huaneng Group and its subsidiaries and associates will have a relatively large increase in 2022.

- 13 -

Pursuant to the current transaction settlement method, the Company and its subsidiaries purchase electricity from power plants of connected persons (including Huaneng Group and its subsidiaries and associates) or electricity sales companies and settle through the grid enterprises in accordance with the contractual agreements between the parties to the transaction. There is no actual settlement relationship between the Company and its connected persons (including Huaneng Group and its subsidiaries and associates), and the transaction amount is determined according to the contractual terms of both parties to the transaction.

Different from the provision of entrusted sales services which involved mainly the use of power generation quota to substitute the power generated by generation companies, electricity purchase is the purchase of electricity generated by power generation companies and sell to customers, using the price difference between transactions to generate economic benefits. In the case of the provision of entrusted sales services, the Company derives the profit out of its own cost control and the fee it charges is similar to processing fee. Given the difference in the nature of the two kinds of transactions, the Company is of the view that the provision of entrusted sales services and the purchase of electricity should not be aggregated under Rule 14A.81 of the Hong Kong Listing Rules.

The Board (including the independent non-executive Directors) is of the view that the transactions for purchase of electricity from Huaneng Group and its subsidiaries and associates by the Company and subsidiaries pursuant to the Huaneng Group Framework Agreement were entered into: (i) in the ordinary and usual course of business of the Company; (ii) on normal commercial terms (on arm's length basis or on terms no less favourable than terms accepted by the Company from independent third parties); and (iii) on terms and proposed caps that are fair and reasonable and in the interest of the Company and its shareholders as a whole.

As none of the applicable percentage ratios relating to the scale of the transactions in question calculated in accordance with Rule 14.07 of the Hong Kong Listing Rules exceeds 5%, such transactions are only subject to the reporting and announcement requirements under Rules 14A.71 and 14A.35 of the Hong Kong Listing Rules but are exempt from the Independent Shareholders' approval requirements. In addition, the Company will, with respect to the transactions in question, comply with the requirements under Rule 14A.55 to 14A.59 of the Hong Kong Listing Rules in respect of the annual review of these continuing connected transactions. If the actual aggregate amount of such transactions during the year ending 31 December 2022 exceeds the above cap (i.e. RMB3.6 billion), the Company will further comply with the requirements under Rule 14A.54 of the Hong Kong Listing Rules.

- 14 -

(8) Sale of electricity

The electricity sale by the Company and its subsidiaries to Huaneng Group and its subsidiaries and associates is mainly attributable to the demand for participation in the electricity market transactions by local government(s) and electricity trading centres organised in their respective regions. The 2021 Huaneng Group Framework Agreement did not provide for such transaction.

During the period from 1 January 2021 to 30 September 2021, the transaction amount in respect of the sale of electricity by the Company and its subsidiaries to Huaneng Group and its subsidiaries and associates was approximately RMB0. It is expected that the accumulative transaction amount for the sale of electricity by the Company and its subsidiaries to Huaneng Group and its subsidiaries and associates in 2021 will not exceed the level that can be exempt from disclosure requirement under the Hong Kong Listing Rules. The Company will closely monitor the relevant transaction amount so as to meet the compliance requirements under the Hong Kong Listing Rules.

- 15 -

According to the Huaneng Group Framework Agreement, the transaction amount with respect to the sale of electricity by the Company and its subsidiaries to Huaneng Group and its subsidiaries and associates in 2022 is estimated to be RMB100 million. Such cap is estimated on the basis of the operation targets of power plants and electricity sales companies of the Company to be achieved and the principle of maximising the Company's interests, according to the trading rules promulgated by the government, sale of electricity to power-consuming enterprises or electricity sales companies of related persons by power plants or electricity sales companies of the Company.

Pursuant to the current transaction settlement method, the Company and its subsidiaries sell electricity to users of related persons (including Huaneng Group and its subsidiaries and associates) or electricity sales companies, and settle through the grid enterprises in accordance with the contractual agreement between the parties to the transaction. There is no actual settlement relationship between the Company and its connected persons (including Huaneng Group and its subsidiaries and associates), and the transaction amount is determined according to the contractual terms of both parties to the transaction.

The Board (including the independent non-executive Directors) is of the view that the transactions for sale of electricity to Huaneng Group and its subsidiaries and associates by the Company and subsidiaries pursuant to the Huaneng Group Framework Agreement were entered into: (i) in the ordinary and usual course of business of the Company; (ii) on normal commercial terms (on arm's length basis or on terms no less favourable than terms accepted by the Company from independent third parties); and (iii) on terms and proposed caps that are fair and reasonable and in the interest of the Company and its shareholders as a whole.

As none of the applicable percentage ratios relating to the scale of the transactions in question calculated in accordance with Rule 14.07 of the Hong Kong Listing Rules exceed 5%, such transactions are only subject to the reporting and announcement requirements under Rules 14A.71 and 14A.35 of the Hong Kong Listing Rules but are exempt from the Independent Shareholders' approval requirements. In addition, the Company will, with respect to the transactions in question, comply with the requirements under Rule 14A.55 to 14A.59 of the Hong Kong Listing Rules in respect of the annual review of these continuing connected transactions. If the actual aggregate amount of such transactions during the year ending 31 December 2022 exceeds the above cap (i.e. RMB100 million), the Company will further comply with the requirements under Rule 14A.54 of the Hong Kong Listing Rules.

- 16 -

(9) Sale of heat

The Company and its subsidiaries sell heat to Huaneng Group and its subsidiaries and associates, mainly including the sales of industrial steam, hot water and other thermal products produced by the Company's power plants and heating enterprises. Pursuant to the provisions of the 2021 Huaneng Group Framework Agreement with respect to the sale of heat by the Company and its subsidiaries to Huaneng Group and its subsidiaries and associates, the cap of the aggregate transaction amount for 2021 was set at RMB100 million. During the period from 1 January 2021 to 30 September 2021, the transaction amount (unaudited) in respect of the sale of heat by the Company and its subsidiaries to Huaneng Group and its subsidiaries and associates was RMB8 million. It is estimated that by the end of 2021, the actual aggregate transaction amount will not exceed the anticipated transaction amount for 2021.

According to the Huaneng Group Framework Agreement, the transaction amount with respect to the sale of heat by the Company and its subsidiaries to Huaneng Group and its subsidiaries and associates in 2022 is estimated to be RMB300 million. Such cap is estimated based on the current overall business scale and operation of the power plants of the Company and its subsidiaries, and the reasonable expectations of the Company and its subsidiaries for the development of these power plants, and also taking into account Huaneng Group and its subsidiaries and its associates can reduce the management and operating costs of the Company and its subsidiaries, thereby improving the Company's operating performance.

The Board (including the independent non-executive Directors) is of the view that the transactions for sale of heat to Huaneng Group and its subsidiaries and associates by the Company and subsidiaries pursuant to the Huaneng Group Framework Agreement were entered into: (i) in the ordinary and usual course of business of the Company; (ii) on normal commercial terms (on arm's length basis or on terms no less favourable than terms accepted by the Company from independent third parties); and (iii) on terms and proposed caps that are fair and reasonable and in the interest of the Company and its shareholders as a whole.

As none of the applicable percentage ratios relating to the scale of the transactions in question calculated in accordance with Rule 14.07 of the Hong Kong Listing Rules exceed 5%, such transactions are only subject to the reporting and announcement requirements under Rules 14A.71 and 14A.35 of the Hong Kong Listing Rules but are exempt from the Independent Shareholders' approval requirements. In addition, the Company will, with respect to the transactions in question, comply with the requirements under Rule 14A.55 to 14A.59 of the Hong Kong Listing Rules in respect of the annual review of these continuing connected transactions. If the actual aggregate amount of such transactions during the year ending 31 December 2022 exceeds the above cap (i.e. RMB300 million), the Company will further comply with the requirements under Rule 14A.54 of the Hong Kong Listing Rules.

(10) Borrowing trust loans and accepting loans

Borrowing trust loans is direct borrowing of trust loans by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates without the involvement of any agent bank as an intermediary, whereas accepting loans loan is primarily organized between Company and its subsidiaries and Huaneng Group and its subsidiaries and associates with a trustee or agent bank acting as an intermediary (entrusted loan), or through the mode of direct transaction. The Huaneng Group Framework Agreement has also included (i) borrowing of trust loans by the Company and its subsidiaries from Huaneng Group and its subsidiaries and associates; and (ii) the provision of loans from Huaneng Group and its subsidiaries and associates to the Company and its subsidiaries. For reasons as set out in the paragraph below, the trust loans and the loans under the Huaneng Group Framework Agreement are exempted the reporting, announcement and Independent Shareholders' requirements under the Hong Kong Listing Rules. The setting of the cap of the transaction amount (i.e. interest arising from borrowing of the relevant trust loans) of the trust loans borrowed and the transaction amount (i.e. the amount of the loans accepted) of the loans received is to comply with the disclosure requirements under the SSE Listing Rules. The cap of the amount of interest arising from the transactions (i.e. interest arising from borrowing of the relevant trust loans) of the trust loans borrowed for 2022 is expected to be RMB200 million and the transaction amount (i.e. the amount of the loans accepted) of the loans received for 2022 is expected to be RMB15 billion or its equivalent in foreign currency (maximum daily balance of the loan).

Given that the trust loans and loans are obtained by the Company and its subsidiaries from or through Huaneng Group and its subsidiaries and associates on normal commercial terms which are comparable to or more favourable than those available from independent third parties for similar services in the PRC and that no security is granted over the assets of the Company and its subsidiaries in respect of such services, the trust loans and loans contemplated under the Huaneng Group Framework Agreement are exempted from all the reporting, announcement and Independent Shareholders' approval requirements pursuant to Rule 14A.90 (which relates to financial assistance) of the Hong Kong Listing Rules. The Company therefore only makes disclosure in light of the Company's announcement disclosed on the Shanghai Stock Exchange.

Fairness of the continuing connected transactions under the Huaneng Group Framework Agreement and their impacts on the independency of the Company

The Huaneng Group Framework Agreement is signed on normal commercial terms which are fair and reasonable, with the prices/fees/interests agreed and confirmed by both parties by negotiating and concluding with arm's length terms, taking into account the then prevailing market conditions, and the terms of the relevant agreement and the transactions under such agreement offered to the Company and its subsidiaries by Huaneng Group and its subsidiaries and associates are no less favourable than those available from independent third parties. The Company and its subsidiaries will sign necessary written agreements on specific transactions with Huaneng Group and its subsidiaries and associates within the range set by the above-stated framework agreement according to actual conditions, and pay and/or charge the relevant prices/ fees/interests based on the agreed method set forth in the relevant agreements.

- 18 -

The Company will, through the Huaneng Group Framework Agreement and a series of management arrangements in accordance with the regulatory requirements, maintain its independency in decision-making, the fairness of the prices of the transactions as well as the flexibility of the Company in connected transactions so as to alleviate the independence on its controlling shareholder. Such arrangements shall include without limitation the Company's right to make independent decisions as to the price and quantity of purchase and to access and obtain market information through various means so that the terms obtained by the Company from Huaneng Group will be no less favorable than those available from independent third parties.

Based on the above, the Company is of the opinion that the Huaneng Group Framework Agreement and the continuing connected transactions thereunder are in the interests of the Company and the shareholders as a whole. Meanwhile, the Company has a complete business system and the ability to operate independently facing the market, therefore the above-stated framework agreements and the continuing connected transactions contemplated thereunder do not affect the independency of the Company.

Measures to safeguard the interest of the Independent Shareholders

Directors and senior management of the Company will monitor closely and review regularly each continuing connected transaction of the Company, and will adopt a series of risk management arrangements, and endeavour to maintain, in relation to each continuing connected transaction, the independence of the Company; the fairness of the price of the transaction; the fairness of the terms of the transaction; and the right of choice of the Company to conduct transactions with independent third parties other than Huaneng Group and its subsidiaries and associates. The relevant arrangements include:

the continuing connected transactions contemplated under the Huaneng Group Framework Agreement are conducted on a non-exclusive basis;
for transactions relating to the purchase of ancillary equipment and parts, the Company has a choice in selecting the procurement. In participating the Company's procurement auction by Huaneng Group and its subsidiaries and associates, the Company will ensure that the prices will be no less favourable than the procurement prices offered to the Company and its subsidiaries. To better understand the market trend, and to compare prices and bid prices during the auction process, the Company will conduct such transactions according to the Company's procurement policy, which mainly stipulates that at times when there are needs for purchasing transactions, the Company will, from time to time, obtain quotations from reputable suppliers (including Huaneng Group and its subsidiaries and associates) and/or invite tenders from multiple suppliers and/or in certain circumstances make price enquiries. According to the Company's procurement policy, in addition to the offer of same or more favourable terms by the counterparty in a transaction, the Company will also consider other factors, including the corporate background of the counterparty; its reputation and reliability; its ability to conduct the transaction in accordance with the terms of the contract; and its understanding of the Company's needs, in order to maximise the Company's interest in the transaction and at the same time reduce the Company's time and costs of transaction;

- 19 -

for transactions in relation to the purchase of fuel and coal transportation services, the Company has established a dedicated mechanism for information exchange and weekly and monthly information analysis, which mainly consists of: (i) collection of price information, such as pithead prices, listed prices at major coal production localities, inland coal transaction price indices, port price indices, domestic futures indices, global coal prices, and price indices of imported coal; and in addition, information relating to the storage at harbours, the production, transportation and sale of coal, and price indices of freights is also collected as an aid in analysing the trend of the market price. The major information collection channels of the Company include: China Coal Market website 中國煤炭市場網 (http://www.cctd.com.cn), China Coal Resources website 中國煤炭資源網(http://www.sxcoal.com) and Qinhuangdao Coal website 秦皇島煤炭網 (http://www.cqcoal.com), etc.; (ii) the Company has also established the Qinhuangdao distribution centre, which is charged with the monitoring of the daily, weekly and monthly prices of coal based on port and water transportation and related developments; (iii) the Company's branch companies and power plants are charged with collecting information on the market and pithead prices of their own location. In terms of pricing, the Company will issue weekly the guidance procurement price of coal for coastal power plants (based on the market information collected and generally lower than the then prevailing market price), the Company will invite at least three suppliers (including Huaneng Group and its subsidiaries and associates) to provide coal quotations within the range of the guidance procurement price as well as the price for transportation services. The Company shall assess the quotations based on factors such as quality, locality and market conditions, in order to determine the appropriate price for the purchase of fuel and the price for coal transportation. If two or more of the quotations obtained fall within the price for the purchase of fuel and coal transportation, factors such as the long-term relationship between the Company and the local large-scale coal enterprise and the ability of such enterprise to provide a stable supply of coal will be considered before the Company makes a final decision to purchase the fuel and coal transportation services. The Company will independently choose and purchase from the best offer according to the market conditions relied upon in developing the Company's procurement strategies. The Company will independently choose and purchase from the best offer according to the market conditions relied upon in developing the Company's procurement strategies.
