NGESO opens tender for reactive power services in Mersey region

National Grid ESO has opened a tender for suppliers of reactive power services in the Mersey region, seeking services from transmission and distribution-connected (33kV and above) providers and from aggregators.

Providers must be ready to supply the service – reactive power absorption – from 1 April 2022 and the contract will last until end March 2031. Providers must be available for the whole nine-year contract period, during which time NGESO expects the need for the service to be more frequent. The tender follows a one-year tender for reactive services in the region launched in October (see below).

The service is open to Balancing Market and non-Balancing Market providers, who do not need to be a CUSC or BSC party.

Providers must submit technical data to NGESO by 13 December because the service is location-specific. NGESO options in different locations, connected at different voltage levels or of different sizes have different impacts on the transmission system voltage. The choice of options at different points will affect the total volume of Reactive Power procured and NGESO will work with distribution network operator SPEN to calculate the effectiveness factors when all technical data is received.

Commercial tenders will be expected by 28 February.
