We own and manage the grids that connect people to the energy they need. In Britain, we run systems that deliver electricity to millions of people, businesses, and communities. We play a vital role in delivering electricity efficiently, reliably, and safely.
Have questions about overhead lines or other assets?
All gas in the UK passes through our transmission network, which supplies gas to power stations and large industrial users. We own and operate the gas transmission network in the UK by working with other companies to make gas available when and where it’s needed.

In this section, you can find information about the role we play in the UK energy industry, how we are regulated, and how our work affects you.
Innovation is at the heart of our business. We continually invest in our networks, making possible the energy systems of tomorrow.
Our wide range of publications provide energy insight and analysis, as well as information about how we are shaping the future of energy in the UK.
Here you will find a complete (a-z) of all balancing services and related areas.

Recover the cost of day-to-day operation of the transmission system. Generators and suppliers are liable for these charges, which are calculated daily as a flat tariff.
Find out about providing a black start service to us. Black start is the procedure to recover from a total or partial shutdown of the transmission system.
On-the-day access to additional generation Balancing Mechanism units (BMUs) that would not otherwise have run.
Demand side response (DSR) is all about intelligent energy use. Find out how DSR can help business and consumers save on total energy costs and reduce their carbon footprint.
Developed to allow demand side providers to increase demand as an economic solution to managing excess renewable generation when demand is low.
Power exchange trades, forward trades, and balancing contract enactment to meet forecast requirements at minimum cost in advance of the balancing mechanism.
EFR is a service, open to both BM and non-BM providers to provide frequency response in one second or less.
Provision of voltage support that exceeds the minimum technical requirement of the obligatory reactive power service (ORPS).
Fast reserve provides rapid and reliable delivery of active power through increasing output from generation or reducing consumption from demand sources.
Firm Frequency Response (FFR) is the firm provision of dynamic or non-dynamic response to changes in frequency. Find out about tendering with us.
To improve and develop our balancing services products and markets, we are investigating what a new, faster-acting frequency response product suite may look like.
A smart, flexible system that makes the best use of all the energy resources available will enable us to meet our customers’ needs in a balanced, efficient and economical way.
Providing clarity around the procurement and assessment of balancing services, in response to provider feedback.
Intertrip services are required as an automatic control arrangement, where generation may be reduced or disconnected following a system fault event.
Mandatory Frequency Response is an automatic change in active power output in response to a frequency change and is a Grid Code requirement.
Provision of varying reactive power output. At any given output generators may be requested to produce or absorb reactive power to help manage system voltages.
Find the forms you need to set up or change bank details with us, to change a reactive meter, change a contact or want to find out about statements, estimates and invoicing.
Short term operating reserve (STOR) is a service that provides additional active power from generation or demand reduction.
The ability for synchronous generation to reduce their minimum generation level (SEL) in times of low demand on the system.
SO to SO services are provided mutually with other transmission system operators connected to Britain's transmission system via interconnectors.
Required where the electricity transmission system is unable to transmit power to the location of demand due to congestion at one or more parts of the transmission network.
