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.

If the generator is successful following the tender assessment, then a market agreement is entered into.

The tender allows the generator to request:

  • an available capability price (£/MVar/hr) and/or a synchronised capability price (£/MVar/hr) and/or a utilisation price (£/MVarh); and
  • the choice of term with a minimum period of 12 months or greater,  in six-month increments (12, 18, 24, 30, 36 months, etc).
