Obligatory Reactive Power Service (ORPS)

The Obligatory Reactive Power Service is the provision of varying Reactive Power output.  At any given output the 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.  The full requirements for the Obligatory Reactive Power Service are referred to in Grid Code CC 6.3.2.

The Obligatory Reactive Power Service is procured via either Market Agreements or Default Payment Arrangements.  Generators can participate in a tender held every six months (for further information see Market Tender Section). National Grid assess the tenders in accordance with the evaluation criteria specified the CUSC. A successful tender then becomes contractually binding. A market agreement is entered into. If a tender is not successful or do not attend a tender, the Generator will be paid on Default Arrangements if they provide the service as instructed.
