Long-term (Y-4)

Since 2020, the Voltage Pathfinders have procured for long-term voltage requirements. The development of a reactive power market provides a route to access voltage services through an open, transparent, and competitive market specific to reactive power.  

The long-term market will now form part of Network Services Procurement and the market will continue to drive locational investment and enable greater competition in the delivery of reactive power service provision. 

NESO have completed system studies and identified needs for locational voltage and stability services across Great Britain from 2029 onwards. We continue to develop our approach for how best to meet these requirements, specifically considering how the long-term markets for both voltage and stability could be utilised. Once we have progressed our thinking, further information will be provided on any future long-term (Y-4)* tender. 

*Y-4 means the tenders will be for delivery four years later.
