National Grid Electricity Transmission plc Annual Report and Accounts 2020/21 1

Overview

About National Grid Electricity Transmission plc

National Grid Electricity Transmission plc (National Grid Electricity Transmission, NGET) is a subsidiary of National Grid plc (National Grid), based in the United Kingdom (UK). We own and operate the regulated electricity transmission network in England and Wales. We do not own the Scottish networks. Our networks comprise approximately 7,236 kilometres of overhead line, 2,806 kilometres of underground cable and 350 substations. We play a vital role in connecting millions of people safely, reliably and efficiently to the energy they use. See pages 6 and 7 for further details.

The governance of National Grid Electricity Transmission is the responsibility of its Board of Directors. Strategic direction is determined by our ultimate parent company, National Grid plc. Our Directors are listed on page 38.

More information on the management structure of National Grid can be found in the National Grid plc Annual Report and Accounts 2020/21 and on National Grid's website at www.nationalgrid.com.

The International Financial Reporting Standard (IFRS) technical requirements make reporting some of the performance measures that we use as a regulated business more complex due to differences in standards used in their generation. We provide additional information, about both our significant assets and liabilities that do not form part of our audited accounts, to help our investors gain a fair, balanced and understandable view of our business.

National Grid Electricity Transmission plc Annual Report and Accounts 2020/21

What we do - Electricity

The electricity industry connects generation sources to homes and businesses through transmission and distribution networks. Companies that pay to use transmission networks buy electricity from generators and sell it to consumers.

The UK electricity industry has five main sectors.

1. Generation

Generation is the production of electricity from fossil fuel and nuclear power stations, as well as renewable sources such as wind and solar. We do not own or operate any electricity generation facilities.

The UK is moving away from a historical reliance on large thermal power generation and there is now a greater diversity of supply and flexible demand than ever before. Therefore, the electricity transmission network has a pivotal role to play in the future energy mix, with evolving roles enabling a range of possible energy futures for the long-term benefit of consumers.

2. Interconnectors

Transmission grids are often interconnected so that energy can flow from one country or region to another. This helps to provide a safe, secure, reliable and affordable energy supply for citizens and society across the region. Interconnectors also allow power suppliers to sell their energy to customers in other countries.

Great Britain (GB) is linked via interconnectors with Ireland, Northern Ireland, France, Belgium and Netherlands. National Grid plc is continuing to work on developing additional interconnector projects, which we believe will deliver significant benefits to consumers. These include two interconnectors currently in construction to Norway and Denmark. The second interconnector with France opened in January 2021.

National Grid, through separate companies held outside of National Grid Electricity Transmission, sells capacity on its UK interconnectors (with France, Belgium and the Netherlands) through auctions.

3. Transmission

Transmission systems generally include overhead lines, underground cables and substations. They connect generation and interconnectors to the distribution system.

We own and operate the transmission network in England and Wales. We no longer operate the electricity operating system. This role is performed by the electricity system operator, National Grid Electricity System Operator Limited, following the separation and sale of this business in April 2019; this business is now owned by National Grid though a separate company held outside of National Grid Electricity Transmission. National Grid Electricity Transmission worked in a joint venture with Scottish Power Transmission to construct a connection to reinforce the GB transmission system between Scotland and England and Wales, The Western Link HVDC was successfully commissioned during 2019/20.

4. Distribution

Distribution systems carry lower voltages than transmission systems over networks of overhead lines, underground cables and substations. They take over the role of transporting electricity from the transmission network, and deliver it to consumers at a voltage they can use.

National Grid, through separate companies held outside of National Grid Electricity Transmission, owns and operates electricity distribution networks in England, having acquired them on 14 June 2021.

5. Supply

The supply of electricity involves the buying of electricity and selling it on to customers. It also involves customer services, billing and the collection of customer accounts.

We do not sell electricity to consumers.

What we do - Regulation

Our business operates as a regulated monopoly. We have one economic regulator for our business, Office of Gas and Electricity Markets (Ofgem). The regulator puts in place an incentive regime that ensures our interests are aligned with those of customers and society

The purpose of the regulatory regime

Ofgem's regulatory regime for the energy industry is titled RIIO, which stands for Revenue = Incentives + Innovation + Outputs. This title reflects the policy purpose of the regime. It is designed to encourage companies to invest in efficiency and innovation, creating value that is shared, through the regulatory mechanisms, between the company (and hence creating the incentive) and the customer. It ensures that companies drive to deliver the outputs their customers want and also creates the opportunity for funding schemes with wider societal benefits.

How we manage our regulated assets

Our licence, established under the Electricity Act 1989, as amended (the Act) requires us to develop, maintain and operate economic and efficient networks . It also gives us statutory powers. These include the right to bury our wires or cables under public highways and the ability to use compulsory powers to purchase land so we can conduct our business.

Our network is regulated by Ofgem, which has a statutory duty under the Act to protect the interests of consumers. Ofgem also has responsibility to enable competition and innovation to drive down prices and introduce new products and services; and deliver a net zero economy at lowest cost to consumers. To protect consumers from the ability of companies to set unduly high prices, Ofgem has established price controls that limit the amount of revenue our regulated business can earn. In setting price controls, Ofgem must also have regard to the need to secure that licence holders are able to finance their obligations under the Act. Licensees and other affected parties can appeal licence modifications which have errors, including in respect of financeability.

The price control includes a number of mechanisms designed to help achieve its objectives. These include financial incentives that encourage us to:

  • efficiently deliver by investment and maintenance the network outputs that customers and stakeholders require, including reliable supplies, new connections and infrastructure capacity; and
  • innovate in order to continuously improve the services we give our customers, stakeholders and communities.

Since 1 April 2019, the electricity system operator licence has been held by National Grid Electricity System Operator Limited (NGESO). NGESO is a separate legal entity from National Grid Electricity Transmission plc, but is a National Grid Group company. To further ensure appropriate ring-fencing between itself and the rest of the National Grid Group, NGESO is governed by its own Board of Directors including three independent directors.

National Grid Electricity Transmission plc retains the electricity transmission licence.

RIIO Price Controls

The building blocks of the RIIO price control are broadly similar to the historical price controls used in the UK. However, there are some significant differences in the mechanics of the calculations.

How is revenue calculated?

Under RIIO, the outputs we deliver are clearly articulated and are integrally linked to the calculation of our allowed revenue, although some outputs and deliverables have only a reputational impact or are linked to legislation. We do not earn allowances if we do not deliver the associated agreed output. These outputs have been determined through an extensive consultation process, which has given stakeholders a greater opportunity to influence the decisions.

There are five output categories for transmission under the current RIIO price controls:

  • Safety - ensuring the provision of a safe energy network.
  • Reliability (and availability) - promoting networks capable of delivering long-term reliability, as well as minimising the number and duration of interruptions experienced over the price control period, and ensuring adaptation to climate change.
  • Environmental impact - encouraging companies to play their role in achieving broader environmental objectives, specifically facilitating the reduction of carbon emissions, as well as minimising their own carbon footprint.
  • Customer and stakeholder satisfaction - maintaining high levels of customer satisfaction and stakeholder engagement, and improving customer satisfaction.
  • Customer connections - encouraging networks to connect customers quickly and efficiently.

Within each of these output categories are a number of primary and secondary deliverables, reflecting what our stakeholders want us to deliver over the remaining price control period. The nature and number of these deliverables varies according to the output category, with some being linked directly to our allowed revenue, some linked to legislation, and others having only a reputational impact.

Totex

Ofgem, using information we have submitted, along with independent assessments, determines the efficient level of expected costs necessary for these deliverables to be achieved. Under RIIO this is known as 'totex', which is a component of total allowable expenditure and is broadly the sum of what was defined in previous price controls as operating expenditure (opex) and capital expenditure (capex).

A number of assumptions are necessary in setting the outputs, such as certain prices or the volumes of work that will be needed. Consequently, there are a number of uncertainty mechanisms within the RIIO framework that can result in adjustments to totex allowances if actual volumes differ from the assumptions. These mechanisms protect us and our customers from windfall gains and losses.
