Short-term (D-1) stability market

In 2021 we launched the Stability Market Design innovation project to explore the design for the enduring stability market.  

This project has recently concluded and AFRY summarised their recommendations in an end of project webinar on 17 July 2023 (slides and recording available on the stability market design webpages).

As a result of this work, in our 2023 Markets Roadmap we set out the aim to procure stability services across several timescales: 

• Long-term (Y-4)
• Mid-term (Y-1) 
• Short-term (D-1) 

We have published a webinar on the short-term stability market in March 2026, to provide industry with an update on our assessment of the potential for a short-term market.

Our Cost Benefit Analysis and Market assessments have demonstrated that there aren’t consumer benefits to the implementation of a full short-term stability power market under current market conditions.
