What Greencells Group does

Greencells Group is a German renewable energy company founded in 2007 and headquartered in Saarbrücken that develops, builds, operates, and finances utility-scale solar projects. The company specializes in engineering, procurement, and construction (EPC) services for utility-scale solar photovoltaic (PV) installations and, more recently, battery energy storage systems (BESS). Its core product surface consists of full-scope Solar PV EPC Services — covering development, engineering, equipment procurement, construction, and commissioning of solar parks — and Turnkey Utility-Scale Battery Energy Storage Systems delivered through a strategic alliance with Desay ESS that combines the partner's battery technology with Greencells' EPC and project delivery capabilities.

Greencells earns revenue primarily through project-based, one-time EPC contracts secured via competitive bidding processes targeting state-owned utilities and large energy providers. Its most material disclosed engagement is the Drombeg Solar Park in County Kerry, Ireland, where it holds an EPC contract with ESB (Electricity Supply Board) for a combined 99MW installation (50MW Phase 1 plus a 44MW Phase 2 extension), won through Ireland's RESS 4 auction. Distribution is direct-to-enterprise, with no intermediary channel, and the company operates primarily in Germany and Ireland with stated ambition to deliver BESS projects "across Europe."

The business is supported by institutional capital, notably a EUR 65 million development bridge financing facility from Kommunalkredit Austria AG (2024) to fund an international green energy portfolio, and is led by CEO Andreas Hoffmann alongside co-founders Marius Kisauer (CFO) and Patrick Clemens (CTO). With 101-250 employees and a project-driven revenue model, Greencells' economics depend on a steady cadence of utility-scale contract wins; concentration risk is elevated given reliance on a small number of state-utility counterparties and auction processes.
