Cubico Sustainable Investments (Cubico), one of the world’s leading privately-owned renewable energy companies, has announced the execution of procurement and construction contracts for its first ready to build Battery Energy Storage System (BESS) project in the United Kingdom.
The Mannington BESS scheme, located in Dorset, will have a capacity of 47.5 megawatts (MW) and 95 megawatt hours (MWh), with a battery duration of 2 hours. On-site construction of the facility, which will be connected to the nearby Mannington 400kV substation, is scheduled to commence in early 2025, with commissioning planned for 2026. Tesla, a global leader in energy storage technology, has been selected as the supplier of the batteries under a Battery Supply Agreement (BSA) and Long-Term Service Agreement (LTSA).
This project, along with other BESS projects being developed by Cubico, will support the UK’s clean energy transition by storing surplus renewable energy, delivering it during peak demand to reduce price volatility, ease grid constraints, and enhance energy reliability.
Mannington is the first in Cubico’s extensive global battery storage pipeline to reach the construction phase. Across the company’s global development portfolio, there are 1.3 GW of battery projects at an advanced stage, with an additional 2.3 GW of greenfield BESS projects in early stages of development.
James Pinney, Head of Northern Europe at Cubico Sustainable Investments commented: “We’re delighted to have executed procurement and construction contracts for our first ready to build battery project in the United Kingdom, a key milestone as we continue to grow our global portfolio in the BESS sector. This achievement is testament to the hard work of our team and highlights our ability to identify market opportunities and deliver a large-scale project with high-quality partners.
“Integrating renewables into power grids requires substantial investment into storage solutions, and we have a growing pipeline of greenfield projects both in the UK and globally that we are now bringing to fruition.”
