Aug 2025Undisclosed stageEquitix (lead); Aware Super; National Wealth Fund$675MEelpower Energy is a newly established UK battery energy storage system (BESS) developer spun out from grid-scale storage developer Eelpower Limited, aimed at building, owning, and operating grid-scale BESS assets to deliver over 1 GW of new capacity to the UK grid. The platform launches with an experienced management team led by CEO Mark Simon, which has been transferred from Eelpower Limited, and Eelpower Limited retains a small minority stake. It plans to immediately begin construction on three BESS projects totaling 300 MWh capacity and target final investment decisions on up to 1 GWh by the end of 2025. On August 27-29, 2025, Equitix-led consortium including Aware Super and the UK's National Wealth Fund invested £500 million (approximately $675 million) to establish and fund Eelpower Energy, with NWF committing up to £200 million specifically for UK projects. Equitix spearheaded the group, partnering with the Australian pension fund Aware Super (managing around A$200 billion in assets) and NWF as a cornerstone investor to support the UK's clean energy transition and attract private capital. The investment reflects confidence in the battery storage sector's role in enhancing grid resilience and achieving net zero goals. The consortium emphasizes the platform's proven track record in delivering grid-scale battery storage, with seed assets ready for construction and a pipeline of high-quality projects for growth. Investors highlight deep expertise in infrastructure, ability to deliver complex energy projects, and attractive risk-weighted returns, while contributing to local impact through cleaner energy infrastructure. This marks ongoing collaborations, such as between NWF and Equitix, and expands Aware Super's UK energy transition portfolio including assets like Forth Ports and EuNetworks. No financial metrics such as post-money valuation, revenue, ARR, or EBITDA for Eelpower or Eelpower Energy are disclosed in the announcements.
Apr 2018Undisclosed stageGCP Infr Investments (lead)$28MEelpower Limited is a UK-based battery storage constructor, owner, and operator focused on building and operating grid-connected battery systems. In April 2018, it secured a £20 million ($28.5 million) debt financing facility from Gravis Capital Management through the GCP Asset Backed Income Fund to construct its pipeline of permitted storage sites and pursue new opportunities in the UK battery storage market. This followed the November 2017 commissioning of its first 10MW Leverton battery storage facility near Lincoln, which secured a Firm Frequency Response contract from National Grid and a fifteen-year T-4 Capacity Market contract starting in 2020. Eelpower also announced co-located battery units at two low-head river hydro schemes in Yorkshire owned by sister company Barn Energy, marking the first such deployment in the UK. The financing supported Eelpower's expansion plans amid growing demand for flexibility in the UK's transitioning energy system. By July 2018, Eelpower outlined ambitions to deploy 1GW of storage by 2022 with £500 million investment, funded by Gravis and other private investors. It had collaborated with Anesco on 33MW of projects over the prior 10 months, with 10MW near Winchester and 8MW in Cumbria slated for later that year, followed by 80MW in the next six to eight months and 100MW every three to six months thereafter. Revenue streams were expected from Firm Frequency Response contracts, wholesale trading, and other services. Gravis highlighted Eelpower as an early-mover in the UK battery storage sector, aligning with its strategy of financing asset-backed infrastructure with long-term cash flows. The deal underscored market confidence in Eelpower's portfolio scale and growth potential, building on operational milestones like Leverton.
