Obligatory reactive power service (ORPS)

The obligatory reactive power service (ORPS) is the 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 close to its point of connection. All generators covered by the requirements of the Grid Code are required to have the capability to provide reactive power.


Payment for the service will start from the date that the reactive capability has been tested and the final mandatory services agreement (MSA) is signed.

ORPS is paid via the default payment mechanism.

Under the default payment mechanism we pay all service providers for utilisation in £/MVArh. The utilisation payment is updated monthly in line with market indicators as set out in Schedule 3 of the Connection and Use of System Code (CUSC).
