What BLS Energieplan does

BLS Energieplan GmbH is a Berlin-based engineering and consulting firm founded in 1984, operating as a wholly owned subsidiary of Dorsch Gruppe. The company delivers integrated planning and consulting services for the energy transition, with a portfolio spanning geothermal energy, heat pump systems (river water, geothermal, air-source), district heating and cooling networks, combined heat and power (CHP), solar thermal, biomass, power-to-heat, waste heat recovery, and technical building equipment. Its core client base consists of municipal utilities (Stadtwerke), city governments, public institutions (universities, hospitals), and industrial companies across Germany, with documented projects spanning 8 German states and a cross-border engagement with Poland. The company organizes its services around six competence areas (energy economics, project management, transformation, sustainability, network infrastructure technology, technical building equipment) and offers end-to-end project delivery from feasibility study through permitting, construction supervision, and commissioning.

The company's revenue model is professional services fee-based, billed per project or hourly, with services typically acquired through public tendering, direct commissions, or competitive bidding. BLS operates 8 German offices (Berlin, Düsseldorf, Frankfurt, Flensburg, München, Gießen, Eisenhüttenstadt, Greifswald) and has completed more than 6,000 projects over its 41-year history. Key mandates include the €194M UNITED HEAT Görlitz/Zgorzelec cross-border district heating project, the 60 MW Elbe river water heat pump for Hamburger Energiewerke (part of Hamburg's coal phase-out), the Stralsund iKWK plant (BHKW des Jahres 2023), the EUREF Campus Berlin Energiewerkstatt (primary energy factor 0), and the Berlin-Tegel Energiezentrale Ost (52 MW heat, 22 MW cooling). In June 2026 the firm launched a dedicated Geothermie business unit, and it has expanded into adjacent advisory lines including ESG/CSRD consulting, PPA structuring (20+ contracts), and CO2-Differenzverträge bid support (4 successful bids in the first German bidding round). The firm has 170+ employees and holds ISO 9001 certification.
