UK: 40 MWh battery storage site helps power South Wales

Field Newport is operational and offers dynamic frequency response to balance fluctuations in electricity demand, also enabling wholesale market arbitrage to reduce the price of energy during off-peak periods.

Clarke Energy was responsible for the full engineering, procurement and construction, delivered on time and within budget, while Trina Storage acted as supplier and integrator. The battery solution, provided by Trina Storage, includes tier-1 battery racks, power conversion systems (PCS), and an advanced software and control system, seamlessly integrated for optimal performance and lifetime.

This is the third UK project Trina Storage has finalised in partnership with Field and follows on from a 20 MWh battery storage site that opened this July in Gerrards Cross, on the outskirts of London. A fourth venture managed by the pair is expected to be commissioned soon. Once complete, the partnership will see a total of 180MWh of storage capabilities delivered for the UK grid.

Ambitious UK target of 24 GW energy storage by 2030

Large battery storage systems, especially grid storage systems (so-called utility-scale storage), are becoming increasingly dominant, according to the latest forecast of SolarPower Europe. Their share of newly installed capacity is expected to climb to 45% by 2028 (2023: 21%), while the share of commercial storage (commercial and industrial) is expected to rise to 25% (2023: 9%), and the share of private home storage is expected to fall to 29% (2023: 70%).

The UK is the second most important market after Italy in Europe for large-scale battery storage. There, the provision of grid storage by companies is also actively financed through a statutory capacity remuneration mechanism. In addition, there are ambitious national expansion targets for energy storage – 24 GW by 2030. For 2024, SolarPower Europe expects an increase of 3.7 GWh in grid storage (82% of the British battery storage market), and 4.7 GWh annually by 2028 (65% of the British battery storage market).
