6 projects totalling 307 MW / 514 MWh
Energy storage accelerates a clean electric future in the UK

Towards a net zero target

Storage fuels renewable transport investment in the UK

The UK has an ambitious goal to reduce greenhouse gas emissions to be net-zero by 2050. Together with EDF Renewables UK and Ireland (formerly Pivot Power), Wärtsilä teamed up to help the country reach this decarbonisation target. Wärtsilä’s innovative energy storage technology supports Europe’s most powerful electric vehicle charging hub and the UK’s first transmission-connected energy storage and electric vehicle (EV) charging hub. The partnership EDF Renewables accelerates the uptake of low-carbon transport and integrates more renewable power into the National Grid.

Wärtsilä’s total portfolio with EDF Renewables now include six energy storage projects with sites in Kemsley, Cowley, Coventry, Bustleholme, Sundon and Bramford. The storage systems are deploying cutting-edge storage technology including the GEMS Digital Energy Platform and will:

  • Integrate renewable generation cost-effectively
  • Help enhance the reliability of the UK’s electricity system
  • Support EDF Renewables in their roll-out of the innovative Energy Superhub model to enable a rapid electric vehicle (EV) charging network across the country

Cowley

The 50 MW / 50 MWh energy storage system in Cowley is the UK’s first grid-scale energy storage system directly connected to the transmission-network. The project is the first part of what will be the world’s largest hybrid energy storage system.

  • Integrates energy storage, electric vehicle (EV) charging, low carbon heating and smart energy management technologies to decarbonise Oxford by 2040, creating a blueprint for other towns and cities to achieve net zero
  • First portion of the £41 million government-backed Energy Superhub Oxford project led by EDF Renewables
  • This is the first project to go live as part of EDF Renewables’ planned deployment of up to 40 similar sites throughout the UK

The system consists of Wärtsilä Gridsolv Max systems and the GEMS Digital Energy Platform, which dynamically optimises energy systems and provides critical feedback to stakeholders across asset owner, operation and trading value chains.

Kemsley

In Kemsley, Kent, we are building a 50 MW / 50 MWh energy storage facility connected to the high voltage transmission network. The Wärtsilä storage system will respond in milliseconds to fluctuations in electricity supply and demand, charging or discharging to keep the system stable.

  • Essential flexibility to future-proof UK’s electricity system
  • Support more intermittent renewable generation
  • Help the country achieve net zero

Coventry

The Coventry 50 MW / 100 MWh energy storage system will help to ensure clean, affordable and secure electricity supply when more renewables are integrated to the grid.

It will also provide additional power capacity to support the installation of an electric vehicle (EV) charging network designed to accelerate the transition to electric transport. The network will enable ultra-rapid public charging hubs.

The system consists of Wärtsilä’s Gridsolv Quantum modules and the GEMS Digital Energy Platform that optimises the energy system.

Bustleholme

The Bustleholme 50 MW / 100 MWh energy storage system helps to ensure clean, affordable and secure electricity supply when more renewables are integrated to the grid.

Just like the Coventry system, it also provides additional power capacity to support the installation of the electric vehicle (EV) charging network that will accelerate the transition to electric transport and enable ultra-rapid public charging hubs.

The system consists of our Wärtsilä Gridsolv Quantum energy storage system, and our advanced GEMS Digital Energy Platform.

Sundon

We will deliver a new grid-scale energy storage facility in Sundon, Bedfordshire, UK. The 50 MW / 100 MWh project, which will form part of a new Energy Superhub in the region, will help to support the transition to a decarbonised electricity system and accelerate the UK’s net zero future.

Bramford

We will deliver a grid-scale energy storage system in Bramford, UK. The 57 MW / 114 MWh project will support the transition to a decarbonised electricity system and help achieve the UK’s net zero goals. The new storage facility will be connected to the transmission network, enabling the integration of renewable energy into the grid. The facility will also strengthen the resilience of the electricity system.

Delivering clean, smart and flexible power

The integration of grid-scale batteries with the charging stations provides grid balancing services, plus the sophisticated GEMS software focuses on performance optimisation. These systems provide several services—such as frequency regulation—and for each service, they generate a different value stream. GEMS’ data-based intelligence optimises the suite of ancillary services to support the grid. In doing so, GEMS helps generate revenue, enabling EDF Renewables to benefit from multiple revenue streams—while also supplying balancing services for the UK National Grid.

The deployment of these systems showcases Wärtsilä’s competencies in optimising energy systems and combining multiple power generation assets into a flexible and reliable solution that can dynamically adjust according to the market demands. Energy storage will continue to provide the needed flexibility and reliability to support renewables and their integration in the UK.
