INSIDE INFORMATION ANNOUNCEMENT

DEMOLITION OF YUNTAI MOUNTAIN WIND FARM

This announcement is made pursuant to Rule 13.09 of the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited (the "Listing Rules") and the Inside Information Provisions (as defined under the Listing Rules) under Part XIVA of the Securities and Futures Ordinance (Chapter 571 of the Laws of Hong Kong).

Huaneng Renewables Corporation Limited (the "Company", together with its subsidiaries, the "Group") has a total installed capacity of 12,094.3 MW as of 30 June 2019, of which installed wind power capacity amounted to 11,162.8 MW. The Company's Yuntai mountain wind farm (the "Yuntai Mountain Wind Farm"), located in the eastern Yuntai Mountain Village, Nanhua County, Chuxiongyi Autonomous Perfecture, Yunnan Province, China, covering 28.89 hectares of the Sanfeng Mountain National Reserve* (the "National Reserve"), was completed and put into operation from 2014-2016, and has an installed capacity of 99 MW, representing approximately 0.89% of the total installed wind power capacity, and approximately 0.77% of the total installed capacity of the Company.

The Company recently received a notice issued by the Yunnan National Forestry and Grassland Administration of the PRC, disagreeing with the decision of the Chuxiong People's Government in 2012 adjusting the plot in the National Reserve for setting aside land for the construction of Yuntai Mountain Wind Farm. The Company immediately met and discussed with the Chuxiong People's Government and its subsidiary, the Nanhua County Government, on the handling of the Yuntai Mountain Wind Farm. After the meeting, the Company carried out a series of assessments on the demolition of the Yuntai Mountain Wind Farm and vegetation restoration, in order to devise a rectification plan (the "Rectification Plan"), and maintained continuous communication with the Chuxiong People's Government and the Nanhua County Government on the rectification work. Based on the above assessments and the latest developments in the continuous communication with the relevant government departments, as at the date of this announcement, the Company has obtained the approval and consent of the relevant government departments in relation to the Rectification Plan and related work details. According to the Rectification Plan, the Company shall complete the demolition

of the Yuntai Mountain Wind Farm on or before 20 December 2019, and complete the vegetation restoration on or before 30 December 2019, in accordance with the requirements of the Chuxiong People's Government and the Nanhua County Government.

The Company has proactively taken a number of initiatives, including considering plans to rebuild a wind farm at another location, formulating plans on the re-use of equipment, actively exploring with local governments to apply for specific subsidies related to environmental protection, and obtaining government support for the implementation of electricity prices, with a view to reducing the impact of the demolition of the Yuntai Mountain Wind Farm to the Company. The Company expects the demolition of the Yuntai Mountain Wind Farm and the related vegetation restoration might cause additional expenses to the Group.

Shareholders and potential investors of the Company are advised to exercise caution when dealing in the shares of the Company.

The Company will make further announcements in relation to major updates of the demolition of the Yuntai Mountain Wind Farm if necessary.

In the meantime, trading in the shares of the Company on The Stock Exchange of Hong Kong Limited shall remain halted pending the release of an announcement pursuant to the Hong Kong Code on Takeovers and Mergers.
