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.

Tenders

ERPS is procured via tenders. Generators can participate in these tenders, which are held every six months. You can find details of the latest tender round on the Market Information tab.

Tender outcome

  • If the generator is successful following tender assessment in accordance with the evaluation criteria specified in the Connection and Use of System Code (CUSC), then a market agreement is entered into.
  • If a tender is not successful and the generator is required to provide ORPS then they will continue on default arrangements for the ORPS requirements.
  • If a tender is not successful and the generator is not required to provide ORPS, then no payments will be made
