About The Position

Lydian is an established energy development company specializing in the development and construction of utility-scale solar and battery energy storage system (BESS) projects in North America. Lydian owns 14 assets in development, construction or under operation, consisting of both solar and storage, which reached or are expected to reach FNTP from 2024-2028. Lydian is backed by Excelsior Energy Capital (“EEC”), a leading private equity fund manager with more than $1.5B in assets under management, that is exclusively focused on north American middle market renewables investing. Lydian’s relationship with EEC provides several critical advantages, including access to (i) a specialized team of value-add investor-operators with decades of renewables development, construction, and transaction experience and (ii) committed discretionary equity capital, strong relationships with debt and tax equity investors, and deep experience structuring tax equity and project financings. Lydian has built a team of seasoned, passionate energy infrastructure professionals with deep expertise in project development, construction, financing, and M&A.
