2 projects totalling 500 MW / 1 GWh

Powering a future of renewable energy

Optimising storage-plus-wind

With the UK targeting 100% greenhouse gas emission reductions by 2050, integrating energy storage technologies with the grid for more efficient and flexible energy dispatchability has become a major priority.

The 200 MW / 400 MWh and 300 MW / 600 MWh energy storage systems (ESS) will deliver stability services using transmission-connected batteries, which will support the UK’s transition to a zero-carbon energy network by preparing the grid for an increased supply of renewables. The systems will provide important stabilisation for the grid, which has traditionally been supplied by fossil fuel-powered generators.

Reliability coupled with innovation

Improving long-term grid stability

The energy storage systems will be be delivered under National Grid’s NOA Stability Pathfinder Programme to improve the long-term stability of the electricity system. Owned by Zenobē, the systems will assist grid operators in the management of challenges related to balancing supply and demand, power stability and constraints.

The systems will provide stability services to the National Grid Electricity System Operator, including short-circuit level and true synthetic inertia, which are essential for the grid to function efficiently as fossil fuel plants phase out.

The first project comprises Wärtsilä’s GridSolv Quantum energy system and the second project will be the first facility built with Wärtsilä’s Quantum High Energy system. Both projects are robustly supported by Wärtsilä’s GEMS Digital Energy Platform. GEMS will manage the complete system to optimise operations and ease network constraints by importing electricity at times of peak renewable generation.
