Eclipse Power Networks

What Eclipse Power Networks does

Eclipse Power Networks is an OFGEM-licensed Independent Distribution Network Operator (IDNO) that designs, owns, operates and maintains electricity distribution networks across Great Britain, offering large energy infrastructure developers an alternative to the incumbent regional Distribution Network Operators (DNOs). The company operates across voltage levels from LV up to 132kV EHV, including 132kV, 66kV, 33kV, 11kV and LV connections, and serves primary end-markets in EV charging hubs, battery storage and generation, hyperscale and colocation data centres, residential and mixed-use property developments, industrial and commercial estates, and port electrification. Its core commercial mechanism is the Asset Value (AV) contribution model — Eclipse pays developers an AV sum to adopt newly built contestable networks and then operates those assets for their full lifetime under its IDNO licence, earning regulated Distribution Use of System (DUoS) income alongside contestable works adoption fees, grid consultancy fees and microgrid/private network development revenue.

The group is structured across three operating subsidiaries: Eclipse Power Networks (licensed IDNO), Eclipse Power Solutions (grid consultancy, spanning feasibility, application and pre-construction support), and Eclipse Power Optimise (microgrids and private networks). Eclipse Power is a wholly owned subsidiary of the Octopus Sky Fund (Octopus Renewables Infrastructure SCSp), an open-ended evergreen fund managed by Octopus Renewables Limited that has raised over £2bn from institutional investors, providing unusually deep long-duration capital for network adoption and AV payments. The company is headquartered in Milton Keynes with a London office, and in November 2025 announced the acquisition of Vattenfall Networks Ltd, which on close will position the combined group as one of the UK's leading IDNOs. Notable contracted projects include the 150MW Minety battery storage site, the 60MW HH4 data centre connection for NTT, the Winchester EV Superhub for InstaVolt (UK's largest ultra-rapid charging hub at signing), the UK's largest zero-bill microgrid in Essex with Octopus Energy, and adoption of major London developments including South Quay Plaza Valiant Tower, Consort Place, Whiteleys of Bayswater and Olympia London. Leadership transitioned from Spencer Thompson to Emma Ford as CEO in January 2026.

Revenue model

1. Network Adoption and Asset Value (AV) Contributions: Eclipse Power pays developers an Asset Value (AV) contribution to adopt their electricity network assets. Once adopted, Eclipse operates and maintains the network under its OFGEM licence for the lifetime of the assets, generating long-term regulated income through DUoS (Distribution Use of System) charges.
2. Contestable Works Adoption Fees: Revenue generated from adopting contestable electricity network works constructed by ICPs (Independent Connection Providers) on behalf of developers. Eclipse oversees, verifies and approves all aspects of connection infrastructure work.
3. Grid Consultancy Professional Services: Fees charged for expert grid consultancy services including pre-application feasibility studies, grid application preparation, offer appraisal, and pre-construction support. Services are provided across distribution and transmission voltage levels.
4. Private Network and Microgrid Development: Eclipse Power Optimise designs, builds and operates private networks and microgrids for developers and property owners, generating revenue through development fees, operational contracts, and joint venture arrangements.
