Project Overview

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.

Reactive Utilisation-Sep-2021

Reactive power utilisation figures per Balancing Mechanism Unit per month. Lag and lead are separated out to show the volume of reactive absorption and generation per unit per month. This file is updated during the middle of each month, and holds data up until 2 months ago, e.g. in December 2019 there is data up until October 2019. Default/Market - D means this reactive power provision was obtained via ORPS, while M would mean it was obtained through Enhanced Reactive Power Service (ERPS). Location - A letter to denote where the unit is located (S = South, N = North, SC = Scotland, M = Midlands)
