Flexibility Focus: Q2 2025
The UK’s journey to Clean Power 2030 depends on a huge increase in system flexibility – and demand-side response (DSR) is set to triple from under 4GW today to nearly 12GW by the end of the decade.
Our new Flexibility Focus report is a quarterly insight into the key market, policy and regulatory developments affecting consumer-led flexibility (CLF), otherwise known as DSR – and the revenue opportunities available to businesses.
In our latest report, reflecting on Q2 2025, and looking forward to Q3, we discuss:
- Wholesale dynamics: Negative and near-zero prices created strong within-day spreads, with flexibility worth up to £142.93/MWh in April.
- Delivered cost savings: Peak demand shaving offered even higher value, reaching £199/MWh on some days.
- Demand Flexibility Service (DFS): Since its restart in late 2024, DFS has delivered 7,865MWh of turn-down capacity, with industrial and commercial customers contributing 40%.
- Policy shifts ahead: Decisions on REMA and the Low Carbon Flexibility Roadmap could reshape electricity market design and support CLF growth.
- New opportunities: NESO’s Slow Reserve service, set to replace STOR in October, will create fresh revenue streams for fast-acting flexible assets.
