What Ion Ventures does
Ion Ventures is an international energy transition developer founded in 2018 and headquartered in London with a regional office in Singapore. The company develops, builds, owns, and operates utility-scale battery energy storage systems (BESS), solar PV, and grid flexibility assets across the UK & Ireland, Continental Europe (notably Romania), South Asia (Bangladesh and India), and Southeast Asia (Indonesia, Malaysia, the Philippines, and Brunei). It manages the full project lifecycle in-house — from site identification, grid connection, and planning through EPC management, commissioning, and long-term asset optimisation — and partners with technology vendors on a technology-agnostic basis, including trials of solid-state sodium battery technology with LiNa Energy.
The company's business model combines long-term asset ownership with managed services delivered to the Flexion Energy joint venture (a £150m GLIL Infrastructure-backed UK storage vehicle co-founded by ion Ventures' co-founders) and grant-funded innovation projects (Innovate UK and BEIS). Revenue derives from energy arbitrage, ancillary services, and capacity market contracts on owned assets; development, operational, and asset management fees from Flexion Energy; EPC management revenue; and innovation grants. Customers span four segments: governments and state-owned utilities (PT PLN Nusantara Power, TNB Research), institutional infrastructure investors (GLIL Infrastructure via Flexion), landowners for site origination, and emerging-market energy access projects (Zembo Uganda, Zonke Energy South Africa).
Ion Ventures operates a B2B enterprise field-sales motion complemented by regional channel partnerships (PT Inovasi Indonesia, OSCO Brunei) and active industry-body participation (Global Solar Council Finance Task Force chair, Energy UK, World Energy Council). It was ranked 19th in the 2024 Deloitte UK Technology Fast 50 (4th in Cleantech) with 2,082% three-year revenue growth and holds a growing 1GW+ pipeline across all four operating regions.
