Energy Capital Partners
MediumFirm Overview
Energy Capital Partners (ECP) is an American investment firm that specializes in the energy sector, including power generation, renewables, and infrastructure.
Energy Capital Partners (ECP) was founded in 2005 by former Goldman Sachs executives Doug Kimmelman, Thomas Lane, and Scott Helm. Based in Summit, New Jersey, the firm established itself early on by raising one of the largest debut funds at the time. ECP focuses on large-scale investments in power generation, renewable energy, energy storage, and midstream infrastructure.
In August 2024, ECP merged with Bridgepoint Group to form a major private assets investment platform, a move designed to expand its footprint in Europe. The firm has also recently pivoted toward supporting the technological sector, forming multi-billion dollar partnerships with KKR and ADQ to develop data centers and power generation capacity required for artificial intelligence.
The firm operates across multiple investment products, including private equity, private credit, and mezzanine capital. ECP has been involved in some of the largest transactions in the energy space, including the historical leveraged buyout of Energy Future Holdings and the record-breaking exit of Calpine to Constellation Energy in 2025.
