What G2 Energy does

G2 Energy (g2 Energy Limited) is a privately-held UK High Voltage Electrical and Civil engineering firm specialising in the design and construction of 'Balance of Plant' infrastructure for power grid connections. Founded in 2011 and headquartered in Olney, Buckinghamshire, the company is registered as g2 Energy Limited (company number 05840192) and operates as a Lloyds NERS-accredited Independent Connection Provider (ICP) with full Contestable Works approval up to 132kV across all UK DNO areas. In July 2016, the group secured an IDNO license from OFGEM, enabling wholly-owned subsidiaries g2 Energy IDNO Ltd and g2 Energy Private Networks to own and operate electricity distribution networks. The company is led by founder and Managing Director Kelvin Ruck.

The firm's core technical capabilities sit in in-house specialist engineering: earthing design using CDEGS, power system studies using DigSilent Power Factory and ERACS, protection and cable design using AMTEC and IPSA, and 3D civil design with BIM-compliant software. A 14,500 sq ft warehouse facility in Milton Keynes, equipped with three operating roof cranes, supports build and testing of bespoke 'gPod' containerised substations, with standard units assembled in under two weeks and capable of grid connection within one week of site delivery. To date the company reports over 340 projects completed and more than 2.1GW of embedded generation connected to the National Grid, spanning solar, wind, battery storage, gas peaking, EV charging, residential and industrial & commercial segments. Beyond the UK, a US-market solar services offering covering engineering, permitting, procurement, installation, monitoring and long-term service agreements (with PPA, capital lease and operating lease structures) is referenced in the revenue model.

Revenue is generated through a mix of project-based professional services for grid connections and contestable works, hardware sales and installation of containerised substations (supply-only or full installation), managed services from IDNO network adoption and operation, and turnkey embedded generation development including lifetime operational management. Pricing is bespoke and quote-based, with contract values typically multi-year. The company sells directly to enterprise clients — including renewable and battery storage developers, commercial real estate developers (e.g., Wood Wharf / Canary Wharf extension) and government clients (e.g., Royal Air Force) — through competitive tenders, repeat client relationships and industry exhibitions. The firm has held three consecutive Sunday Times Virgin Fast Track 100 Top 10 rankings (2013-2015 editions) and ISO 45001 certification.
