List of all balancing services
Here you will find a complete (a-z) of all balancing services and related areas.
List all of balancing services
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.
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.
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.
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.
