Reactive Power is an essential service used by NGESO to control the system voltage level within the limits that are defined in the Grid Code and NETS SQSS. 

Conventional transmission connected sources of reactive power are being replaced by renewable and decentralised units. This change to the generation base, along with a changing demand profile, makes controlling voltage on the NETS more challenging.

The project is to explore if a reactive power market could be developed to help ESO access more reactive power in the right location, create market access for more providers, incentivise more efficient new technologies and lower the overall spend on reactive power control. This will facilitate ESO’s goals to deliver Competition Everywhere, Zero-Carbon System Operation, and Whole Systems Outcomes by 2025.
