The UK has an ambitious goal to reduce greenhouse gas emissions to be net-zero by 2050. Wärtsilä and EDF Renewables UK & Ireland, teamed up to help the country reach this target.
Wärtsilä’s total portfolio with EDF Renewables includes eight energy storage projects with sites in Kemsley, Cowley, Coventry, Bustleholme, Sundon, Bramford, Cornwall, and Greater Manchester. The storage systems are:
| Who | EDF Renewables UK & Ireland |
| What | 8 projects totalling 404.5 MW / 709 MWh |
| Where | United Kingdom |
of energy storage capacity across 8 projects
of energy storage capacity across 8 projects
| Customer | EDF Renewables UK & Ireland |
| Site size | 8 projects totalling 404.5 MW / 709 MWh |
| Site locations | Cowley & Kemsley – each 50 MW / 50 MWh Coventry & Bustleholme – each 50 MW / 100 MWh Sundon – 50 MW / 100 MWh Bramford – 57 MW / 114 MWh Indian Queens – 47.5 MW / 100 MWh Bredbury – 50 MW / 100 MWh |
| Application(s) | Balancing services for the UK National Grid, including: Frequency response, electricity market trading, reactive power, and EV charging services |
| Scope of services | Engineered equipment delivery (EEQ), Service+ GAP |
| Delivery | 2020-2026 |
To date, six out of eight facilities are operational. Indian Queens in Cornwall and Bredbury in Greater Manchester—are currently under construction. Bredbury (50 MW / 100 MWh) is scheduled for completion by late 2025 and Indian Queens (47.5 MW / 95 MWh) is expected to come online in the first half of 2026.
As more facilities become operational, ensuring optimal system performance becomes critical to business success. All eight projects are covered by Wärtsilä’s long-term service agreements, providing EDF Renewables with increased operational efficiency and cost predictability.
