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. Provided here is data on utilisation (in MVARh) of this service per balancing mechanism unit and per month.
NOTE: We are pleased to inform you that a new version of the Reactive Utilisation Data will be released soon. Moving forward, this file will have a fixed number of columns, with the number of rows increasing with each update. This will enhance the look and feel of the data, aimed at providing an improved customer experience in terms of both data consumption and storage.
