We are becoming a separate company

In April 2019, the Electricity System Operator is becoming a separate company within the National Grid Group. Find out more about what this change will mean.

Enhanced reactive power service (ERPS)

The enhanced reactive power service (ERPS) is suitable for generators who can provide reactive power over and above the Grid Code and obligatory reactive power service (ORPS) requirements. On this page, you can find out about the route to market.

Where reactive power services are provided by a generator as a condition of their connection to the transmission system, the reactive capability must exceed the minimum technical requirement of ORPS. The ORPS requirements are set out in the Grid Code section CC 6.3.2.

The service provision will need to be in line with the commercial services agreement awarded in the tender.

Generators are generally instructed to provide a target megavar (MVAr) level which must be reached within two minutes.

Instructions for reactive power are normally sent by us to the generator via an electronic dispatch logging (EDL) system.
