Flagship UK battery storage project

Swindon moves towards energisation

  • Battery energy storage supports the growth of renewables, reducing carbon emissionsand energy costs for consumers, by providing grid stability and reliability
  • SWGT has acquired project from PPS and construction will be getting underway shortly

  • 18th November 2020 Public Power Solutions (PPS), a wholly-owned company of Swindon Borough Council, and Still Waters Green Technology (SWGT), a leading independent battery energy storage system (BESS) asset manager in the UK, are pleased to announce the next phase of their flagship 30MW utility-scale, subsidy-free energy storage project.

    In March 2018 PPS received planning consent for the project, which is on land leased from Swindon Borough Council. The battery facility is designed to have a 30-year lifespan and will offer a substantial land income for Swindon Borough Council. This project will provide up to 65GWh of annual import and export energy capacity to the national grid, with a 25-container all-in-one Lithium Ion BESS integrated solution. Connecting large batteries to the National Grid helps to smooth out the peaks and troughs which occur in power demand, and match them better with variable supply. The batteries can be used to store energy when it is abundant, and therefore cheaper, and discharge it when demand is greater and the cost is higher. It therefore supports the growth of renewable energy sources critical to meeting the UK’s carbon emission reduction targets. The technology also helps reduce the need for expensive investment in upgrading the grid, also helping reduce energy costs for consumers in the long run.

    Bernie Brannan, Managing Director, PPS, said: “We’re very pleased to be moving forward with this exciting technology thanks to our agreement with SWGT. Battery storage is playing an increasingly important role in the UK’s energy infrastructure as more and more renewable energy projects are coming online. This project will help the Borough in its efforts to ‘build back greener’ boosting the local economic recovery, provide an income for Swindon Borough Council, and contribute to the decarbonisation of the UK’s energy sector.”

    Cllr Keith Williams, Swindon Borough Council’s Cabinet Member for Climate Change, said: “The Mannington Battery storage scheme is a big step towards Swindon’s goal of being Carbon Neutral and eliminating the reliance on fossil fuels to supply electricity during peak periods. This privately-funded partnership demonstrates the commercial viability of schemes like this and I am proud that Swindon is at the forefront of such innovations in the U.K.”

    Olivia He, Chief Investment Officer at SWGT said: “This project is testimony to the resilience of the energy transition fuelled by innovation and a strong appetite for renewable energy from investors. It establishes a solid foundation for SWGT’s growth ambition and vision to become the preeminent UK renewable energy sponsor, supporting the integration of low-carbon power generation locally and worldwide. We would like to thank all the stakeholders’ support in PPS and SBC who contributed to the success of the inaugural phase of the project, especially during this difficult time with COVID-19.”

    The battery storage scheme will be built on a brownfield site at the former Mannington municipal depot owned by the Council, enclosed between the A3102, railway line and Mannington Retail Park.
