What Pulse Clean Energy does
Pulse Clean Energy Limited is a UK-based developer, owner and operator of utility-scale battery energy storage systems (BESS) headquartered in London. Founded in 2009 as Green Frog Power and wholly acquired by the Investment Management Corporation of Ontario (IMCO) in October 2021, the company was rebranded as Pulse Clean Energy in February 2022 and targets more than 2GWh of installed capacity by 2030. Its core product is grid-scale lithium iron phosphate BESS assets that store electricity during surplus renewable generation and dispatch it during high-demand periods, providing frequency response, grid balancing and ancillary services to NESO and the UK's Distribution Network Operators. Pulse differentiates through a diesel-to-battery conversion programme that has repurposed nine former diesel sites and through Pathfinder synchronous condenser projects that address falling grid inertia.
The company generates revenue primarily through long-dated grid services contracts with NESO and DNOs for frequency response, balancing and arbitrage, with assets optimised across wholesale and ancillary markets by Habitat Energy using its machine-learning forecasting tools. A secondary stream comes from development fees on diesel-to-battery conversions executed with EPC partners (Canadian Solar, Metka). Pulse has raised over £460M in cumulative green debt facilities (May 2023, August 2025, April 2026) and benefits from IMCO's up to USD $500 million equity commitment.
By September 2025 Pulse had energised seven BESS projects across Greater Manchester, South Wales, Staffordshire, Hampshire, Lancashire and Scotland, with a portfolio including Hyde (42MW/104MWh), Coal Pit (30MW/67MWh), Town Lane (30MW/60MWh), Overhill, Hirwaun, Willoughby, Briton Ferry, Flatworth and Tir John. The customer base is concentrated on UK national and regional grid operators, with ENW and Network Rail named as partners on the Hyde project. Pulse also publishes the UK Storage Asset Emissions Impact Calculator, an industry-first open-source tool for standardised carbon-impact reporting across BESS assets.

Revenue model
- Grid Balancing and Ancillary Services: BESS assets provide grid-balancing services to the UK's National Energy System Operator (NESO) and Distribution Network Operators (DNOs). Revenue is earned through frequency response services, arbitrage (storing electricity during surplus periods and releasing during high demand), and other ancillary services. Habitat Energy optimises assets across wholesale and ancillary service markets using machine learning forecasting and algorithmic dispatch tools.
- Diesel-to-Battery Site Conversion Services: Pulse converts decommissioned diesel generation sites into BESS assets for third parties or its own portfolio, generating development and construction revenue. Partnerships with EPC contractors like Canadian Solar and Metka deliver turnkey BESS facilities.
- Green Debt Financing and Capital Deployment: Pulse raises green debt from international banking consortia (e.g., £220M green finance deal in 2025) and deploys capital into BESS construction and acquisition. The company benefits from Green Loan Principles-aligned financing structured by Santander CIB, with returns generated through asset ownership and operational cash flows over project lifecycles.

- Grid Stability Services (Synchronous Condenser Projects) Synchronous condenser projects developed under National Grid's Pathfinder programme that provide inertia and reactive power to facilitate renewable energy integration into the UK power system, addressing grid stability challenges as coal and gas plants are phased out.
- Hyde Battery Energy Storage Project Utility-scale BESS project at Hyde, West of Manchester developed in collaboration with Electricity North West as DNO and Network Rail. Provides grid balancing and ancillary services for the North West region.
- Coal Pit Battery Energy Storage Project Utility-scale BESS project built on a former coal mining brownfield site in Atherton, Greater Manchester. Delivers approximately 34,000 tonnes of CO2 emissions prevention over the first decade and provides route-to-market balancing services via Flexitricity.
- Town Lane Battery Energy Storage Project Utility-scale BESS project built on a repurposed former scrapyard brownfield site in Lancashire, providing grid-balancing services for the North West region.
Quantifiable outcome
- Each BESS project prevents thousands of tonnes of CO2 emissions annually. Hyde: ~3,500 tCO2/year; Town Lane: ~2,500 tCO2/year; Coal Pit: ~34,000 tCO2 over first decade.

Pulse Clean Energy competitors and assessment
Company assessmentDirect peers
- Harmony Energy: UK-based developer, owner, and operator of utility-scale battery energy storage projects. Directly comparable to Pulse in target customer (NESO, DNOs), project scale (tens to hundreds of MW), and revenue model (ancillary services, frequency response, arbitrage).
- Gore Street Energy Storage Fund: London-listed fund focused on UK grid-scale battery storage assets. Directly comparable as a UK BESS owner-operator with revenue from ancillary services and capacity markets, with similar end customers (NESO, DNOs) and asset sizes.
- Statera Energy: UK developer of large-scale battery storage and flexible generation assets. Directly comparable to Pulse in BESS project development, grid-balancing services revenue, and engagement with NESO and DNOs across UK regions.
- Penso Power: UK BESS developer and operator focused on behind-the-meter and front-of-meter battery storage. Directly comparable in business model (BESS development + revenue stacking) and customer base (UK grid operators).
- Zenobe Energy: UK-headquartered owner and operator of grid-scale battery storage and electric vehicle infrastructure. Directly comparable as a BESS platform competing for the same NESO/DNO contracts and prime UK BESS sites, with a larger operating portfolio.
- Field (formerly Low Carbon): UK-based renewable energy developer with utility-scale solar and battery storage projects. Directly comparable as a BESS developer serving NESO and UK off-takers, with a portfolio approach that overlaps Pulse's grid services focus.
- Arlington Energy: UK developer of battery storage and flexible generation assets. Directly comparable in BESS project development, ancillary services revenue, and engagement with NESO and UK distribution networks.
Emerging players
- BW Energy Storage (BW ESS): BW group's standalone BESS platform, with UK project development and operations as a major focus area. Comparable as a BESS-only owner-operator competing for the same UK projects and ancillary service revenues, though still building out its UK pipeline.
Broad incumbents
- RWE (UK BESS portfolio): Global utility with a large UK battery storage development pipeline alongside wind, solar, and conventional generation. Comparable as a competitor for UK BESS sites and NESO ancillary service contracts, but BESS is one of many businesses in its portfolio.
- Drax Group: UK-listed power generator and renewable energy developer with growing BESS ambitions. Comparable as a UK-based grid services and storage competitor, though BESS is a smaller part of a much larger conventional and renewable generation portfolio.
