Project Solar Technology

What Project Solar Technology does

Project Solar Technology (Projekt Solartechnik sp. z o.o., "PST") is a Poland-based utility-scale renewable energy developer operating as one of four pillars of the Grenevia Group (formerly FAMUR Group, listed on the Warsaw Stock Exchange). Founded in 2012 and headquartered in Katowice, PST develops, finances, constructs, and sells large-scale photovoltaic farms, with growing exposure to onshore wind and battery energy storage (BESS). As of end Q3 2024 the company reported approximately 5 GW of renewable energy projects at various stages of development across Poland and international markets (Germany, Romania, France, Spain), including 1.5 GW in Poland, 134 MW under construction, 500 MW in pipeline, and 1.3 GW of grid connection conditions.

The company's core offering is end-to-end PV project development — from land acquisition (3,872 hectares secured in Poland for PV and 471 hectares for wind) and grid connection through EPC construction to ready-to-build (RtB) or operational status — sold to investors and corporate energy consumers. Recurring revenue is generated through cPPA/PPA contracts managed via the dedicated trading subsidiary PST Trade S.A., which also handles wholesale energy trading, balancing services, and guarantees of origin. Named enterprise customers include KGHM Polska Miedź, Budimex, Famur (Grenevia sister entity), Amiblu Poland, .KTW Buildings, and Respect Energy. The company also provides O&M and farm-repair services for operational PV installations.

PST is funded predominantly through project finance debt rather than equity, having secured a PLN 428 million syndicated loan (ING/Pekao/BNP Paribas), PLN 128 million and PLN 82.5 million loans from the Polish Development Fund (PFR), a PLN 71 million Pekao facility, and bridge financing from Eiffel Investment Group. The company is currently in an active corporate simplification phase, having completed the merger of PST S.A. with PST Development in January 2025, transformed from S.A. to sp. z o.o. in August 2025, and announced further intra-group mergers consolidating ~35+ project SPVs through late 2025. International expansion is led by PST Germany (Dresden), PST Romania, PST France, and PST Spain, supported by dedicated international development leadership.

Core offering

Project Solar Technology develops, constructs, and operates large-scale photovoltaic solar farms, wind farms, and battery energy storage systems (BESS) primarily in Poland and select European markets. The company sells ready-to-build (RtB) and operational PV projects to investors and corporate buyers, and supplies green electricity through corporate Power Purchase Agreements (cPPA/PPA) via its dedicated trading subsidiary PST Trade SA. Supporting services include operations and maintenance (O&M), EPC turnkey construction, and land lease for PV installations.

Product overview

Project Solar Technology (Projekt Solartechnik) operates as a renewable energy project developer within the Grenevia Group, offering an integrated suite of services for photovoltaic and wind energy development. The core product portfolio consists of large-scale PV farms developed from greenfield through construction to operational status, complemented by wind farm development and battery energy storage (BESS) projects. These primary offerings are supported by a range of services including PPA/cPPA energy sales managed through the company's trading entity PST Trade, operations and maintenance (O&M) services, turnkey farm construction, and land lease arrangements for PV installations. The company also sells completed PV projects and project portfolios to investors and industrial customers. The integrated approach allows Project Solar Technology to serve as both a project developer and independent power producer (IPP) with its own generation portfolio.
