What Energy Capital Partners does
Energy Capital Partners (ECP) is a private equity and infrastructure investment firm founded in 2005 by Doug Kimmelman (previously head of Goldman Sachs Power Investing), specializing in energy transition assets including electricity generation, transmission, distribution, and sustainability infrastructure. The firm invests through two primary platforms: equity funds executing value-add, predominantly control investments across electricity and sustainability infrastructure, and a credit platform that has issued over $73 billion in debt capital to energy infrastructure borrowers over the last two decades. Since inception, ECP has raised over $37 billion in capital commitments from 600+ institutional limited partners globally across six flagship equity funds, two energy transition continuation funds, and approximately $9 billion in co-investment vehicles, deploying capital across 78 portfolio companies spanning natural gas and geothermal generation, nuclear services, renewables, LNG infrastructure, waste management, recycling, and emerging digital infrastructure.
ECP's product surface spans electricity infrastructure investments (power generation assets such as the former Calpine portfolio at 26,000 MW across 77 plants, PROENERGY's 2.4 GW gas turbine fleet, and Terra-Gen's 9 GW of wind, solar, storage, and geothermal assets) and sustainability infrastructure investments (Biffa, Liberty Tire Recycling, Pivot Energy, Restaurant Technologies, Atlantica, and Grain LNG). The firm operates with a value-added, operationally focused investment approach, partnering with management teams to drive operational and strategic improvements rather than relying on financial engineering. Revenue mechanics follow standard private equity economics: management fees on committed capital and carried interest on investment gains above a hurdle rate, sourced from institutional investors including pension funds, sovereign wealth funds, insurance companies, and family offices.
In August 2024, ECP combined with London-listed Bridgepoint Group Plc to form a combined alternative asset manager with approximately $87 billion in assets under management spanning private equity, credit, and infrastructure across North America and Europe. The combination extended ECP's geographic reach into the UK middle market and broadened its strategy beyond pure energy infrastructure. Most recently, ECP has positioned itself at the intersection of the AI buildout and power demand through a $50 billion strategic partnership with KKR to develop hyperscale data center infrastructure, a $25 billion US power generation partnership with Abu Dhabi's ADQ, and active deployment across nuclear services (EnergySolutions re-acquisition), LNG (Grain LNG JV with Centrica), and digital infrastructure.
