Key terms

Glossary →
Capacity Market
A scheme that pays power stations, batteries, interconnectors and flexible demand to be available when Great Britain's electricity system is under stress.
Carbon border adjustment mechanism (CBAM)
A charge on the carbon emitted in making certain imported goods, so they face a carbon cost similar to products made under the UK's own carbon market.
Carbon budget
A legally binding cap on the UK's total greenhouse gas emissions over a five-year period, set under the Climate Change Act 2008.
Clean Power 2030
The UK government's mission for Great Britain's electricity to come overwhelmingly from clean sources by 2030, set out in an action plan published in December 2024.
Climate Change Levy (CCL)
A UK tax on the electricity, gas and other fuels that businesses and the public sector use, added to their energy bills by the supplier.
Contracts for Difference (CfD)
The UK government's main scheme for new low-carbon power: generators get a fixed strike price per MWh, topped up or paid back against the market price.
Energy price cap
The maximum unit rates and daily standing charges that suppliers in Great Britain can charge households on default tariffs, set by Ofgem every three months.
Energy security
Having reliable access to the energy a country needs, at prices households and businesses can afford, and being able to withstand supply shocks.
Feed-in Tariff (FIT)
A former Great Britain scheme that paid small-scale generators for electricity they produced and exported. It closed to new applicants in 2019, but existing payments continue.
Great British Energy
A publicly owned, operationally independent clean energy company set up by the UK government and headquartered in Aberdeen.
Levelised cost of electricity (LCOE)
The average cost of each megawatt-hour a power plant produces over its whole life, including building, running, fuel and decommissioning.
Levelised cost of heat (LCOH)
The average lifetime cost of producing one unit of heat from a heating system, usually given in pounds per megawatt-hour of heat.
Net zero
The point at which a country's greenhouse gas emissions are balanced by the amount removed from the atmosphere. UK law requires net zero by 2050.
Ofgem
The independent regulator for the gas and electricity markets in Great Britain, responsible for protecting consumers, setting the price cap and regulating network companies.
Power purchase agreement (PPA)
A long-term contract in which a buyer, often a large business, agrees to buy electricity from a specific generator at an agreed price.
Renewable Energy Guarantees of Origin (REGO)
A certificate issued by Ofgem for each megawatt-hour of renewable electricity generated in the UK, used by suppliers to show how much of their power is renewable.
Renewables Obligation (RO)
The UK's main support scheme for large-scale renewable electricity from 2002 until it closed to new capacity in April 2017. Payments continue until 2037.
Standing charge
A fixed daily amount on a gas or electricity bill that you pay regardless of how much energy you use, even on days when you use none.
Strategic Spatial Energy Plan (SSEP)
A plan being prepared by NESO for the UK, Scottish and Welsh governments that maps where new electricity and hydrogen generation and storage should go in Great Britain.
UK Emissions Trading Scheme (UK ETS)
The UK's carbon market: power stations, heavy industry, aviation and shipping must hold one allowance for every tonne of CO2e they emit, under a shrinking cap.
Wholesale electricity price
The price at which generators sell electricity to suppliers before it reaches homes. In Great Britain it is often set by gas power stations.
Zonal pricing
A wholesale electricity market split into regional zones, each with its own price. The UK government decided in July 2025 to keep a single national price instead.
