Why Investors Backed Belenus Power Group
Belenus Power Group sells maintenance, testing and repair services for high and medium voltage power equipment. Its customers own and run solar plants, battery storage sites and other power generation assets. The company has serviced more than 3 gigawatts of assets since it began. In February 2026 it named Jack Bennett chief executive officer to lead its next stage of growth.
The problem it targets
Belenus's view is that the shift to sustainable energy works only if near-term returns justify the pace of new installations. It treats keeping power assets reliable and performing as the core challenge. Its focus is high and medium voltage equipment that needs expert talent, in-house knowledge and advanced technology. Its pitch is to close the gap between spotting a fault and fixing it, from panel to substation.
What the product does
Belenus offers four service lines. Condition-based responsiveness covers scheduled inspections and emergency callouts. High and medium voltage services cover transformer maintenance, NETA-compliant testing and substation troubleshooting. PV and DC field work covers IV curve tracing, ground fault repair, tracker inspections and inverter troubleshooting. Battery storage support covers preventive maintenance, thermal diagnostics and testing to NERC and NETA standards.
Progress so far
Belenus's case studies include a substation cable replacement for a major utility-scale solar owner, done under active production conditions. Others cover medium-voltage transformer oil reconditioning at a California solar facility and annual substation maintenance across a multi-site portfolio totaling 480 MWdc. One covers due diligence and performance auditing for a power producer weighing the purchase of a distressed solar asset. On February 3, 2026, Belenus announced Bennett as chief executive officer. Co-founder Stephen Lynch said the change puts the right leadership structure in place ahead of scale.
