What Lime Rock New Energy does
Lime Rock New Energy (LRNE) is a growth-focused private equity firm founded in 2019 and headquartered in Connecticut that invests in companies delivering products and services across the energy transition value chain, including renewable energy, grid modernization, energy efficiency, and transportation decarbonization. The firm manages Fund I and Fund II, with Fund II reaching a final close of $640 million in April 2026 — exceeding its $500 million target and doubling the size of its predecessor fund. Capital was sourced from a diversified global institutional base, with approximately one-third of commitments from European and Asian institutions and nearly 90% re-up from existing Fund I limited partners.
LRNE's portfolio currently includes Boulder Imaging, a Colorado-based provider of AI-powered ultra-high-speed machine vision for wind energy and manufacturing (including the IdentiFlight avian detection system deployed across six continents), and Hawk Line Construction, a Midwest utility contractor providing grid infrastructure services. The firm generates revenue through standard private equity fund economics — principally management fees on committed capital, with carried interest on investment returns — and distributes its investment offerings to qualified institutional investors through direct relationship management rather than a platform or product sales motion.
