Descriptiontext

Exagen Group Ltd is a UK-based renewable energy project developer headquartered in London, specializing in hybrid solar and battery storage infrastructure across England. Founded in 2019 by Jeremy Littman, the company develops utility-scale solar farms alongside grid-scale battery energy storage systems, with a development pipeline exceeding 2.4 GW and a flagship 500MW mega-battery storage site planned for the Midlands that is expected to be operational in 2027. The portfolio targets UK energy security and grid stability by combining renewable generation with storage to reduce dependence on gas imports and support the clean energy transition.

The company's business model centers on developing capital-intensive renewable projects, monetizing them through long-term power purchase agreements, grid balancing services, and ultimately asset sales or operational revenue. Exagen secured up to £35 million from the Octopus Energy Development Partnership fund in August 2022 for a 24% stake, and in September 2024 Octopus Energy Generation completed a full acquisition of the company, inheriting the 2.4 GW+ hybrid solar and battery storage portfolio. As a B2B renewables developer, Exagen's customer base is concentrated in the energy sector and utilities segment, including grid operators and energy suppliers seeking renewable generation and storage capacity.

Post-acquisition, Exagen operates as a subsidiary of Octopus Energy Generation, retaining its exagen.co.uk presence. Its competitive positioning rests on access to dedicated renewables capital via Octopus, a hybrid solar-plus-storage pipeline that few UK developers can match at scale, and secured or advancing planning and grid connections for utility-scale assets. No pricing, revenue figures, or AI/ML capabilities are disclosed in the available source material.

openPR.comLeading Companies Fueling Growth and Innovation in the Hybrid Energy Storage MarketThe global hybrid energy storage market is projected to reach $25.27 billion by 2030 with a compound annual growth rate of 8.2%, driven by rising electric vehicle adoption, smart grid development, and declining storage technology costs. In September 2024, UK-based Octopus Energy Generation acquired Exagen Group Ltd, gaining a 2.4 GW+ portfolio of hybrid solar and battery storage projects across England, strengthening its position in the UK's clean energy transition. Additionally, Caterpillar Inc. launched its Cat Hybrid Energy Storage Solution in February 2024, combining bidirectional power inverters, modular battery storage, and microgrid controllers for industrial applications.BitlyLondon’s Octopus Energy launches new €220M fund, makes first investment in ExagenLondon-based Octopus Energy Group announced on August 24 a €220M renewables fund, the Octopus Energy Development Partnership, run by Octopus Energy Generation, targeting solar, onshore wind and storage projects across the UK and Europe.
