What gasag solution plus does

GASAG Solution Plus GmbH is a Berlin-headquartered energy solutions provider and a wholly-owned subsidiary of GASAG AG, Berlin's established municipal gas and energy utility. The company plans, finances, implements, and operates customized green energy supply systems for both new-build and existing buildings, delivered under long-term contracting arrangements (typically 20 years) where it owns and operates the energy infrastructure on the customer's behalf. Its core technology stack spans geothermal deep drilling and probe fields, air-source and reversible heat pumps, combined heat and power (BHKW/CHP) units, photovoltaic and PVT systems, district heating networks (Nahwärmenetze), and — most distinctively — data center waste heat recovery operationalized through the DATA2HEAT joint venture with Investa Real Estate, as well as sewage heat recovery. Notable reference projects include the 64 GWh/year Uber Platz complex in Berlin, the 34 GWh/year Quartier Maselake serving roughly 6,000 residential units, and the planned 29 GWh/year Marienpark data center waste heat scheme.

The company sells exclusively through B2B direct field sales and recurring developer partnerships to four customer segments: property developers and real estate companies (new construction), housing companies and property managers (retrofit/decarbonization under the German Building Energy Act/GEG), municipalities and public institutions, and commercial/industrial property owners. Beyond thermal energy supply, it operates an EV charging infrastructure line (Ladelösungen) and an energy consulting practice covering contracting and energetic retrofit advisory. The pricing model is contract-based with index-linked adjustments (EEX, EGIX, heat price indices); per-unit consumer pricing is not publicly disclosed. The company is operationally based at the EUREF-Campus in Berlin-Schöneberg with a secondary office in Essen (North Rhine-Westphalia), holds ISO 50001:2018 energy management certification, and was awarded the 2025 ZfK NachhaltigkeitsAWARD. Revenue magnitude is not publicly disclosed, but operational energy output across the visible contracted project base is in the tens of GWh per year range, supporting an estimated annual revenue band of approximately $50M-$100M with low confidence given the absence of disclosed financials.
