Sembcorp Energy UK secures 150mw battery storage in capacity market auction


Sembcorp Energy UK (SEUK) announced that it has secured a 15-year contract for 150MW of two-hour duration battery storage (equivalent to 300MWh) in the provisional results for the latest T-4 2025/26 Capacity Market auction. This 150MW tranche, expected to be operational by 2023, is part of a planned total 360MW battery energy storage system announced in December 2021.
Adding to its existing 120MWh battery pipeline, SEUK will have a total battery capacity of 420MWh in the UK.

Batteries can supply power and other services to the national grid within a few milliseconds, providing a secure and stable energy system that will aid the UK’s low-carbon transition.

Andy Koss, CEO, UK & Middle East, Sembcorp Industries, said, “Sembcorp is committed to supporting the energy transition. We recognise that energy storage is essential to the UK’s journey to Net Zero 2050, and we are glad to be able to lead the way in this field. SEUK’s battery portfolio expansion will help ensure the resilience of the electricity network that will enable the continued growth of renewables and help the UK decarbonise.”

This announcement is not expected to have a material impact on the earnings per share and net asset value per share of Sembcorp Industries for the financial year ending December 31, 2022.
