What Limon does

Limón GmbH is a German energy efficiency and climate management consultancy founded in 2007 in Kassel, operating as a subsidiary of EWE AG. The firm serves industrial and commercial enterprises across energy-intensive sectors including automotive manufacturing, steel and metal production, plastics processing, food processing, metalworking/foundries, and energy utilities. Its service portfolio is organized into four pillars: Management Solutions (energy management per DIN EN ISO 50001, energy audits per DIN EN 16247, product and corporate carbon footprinting, CSRD/ESRS sustainability reporting, ESG advisory), Technical Solutions (efficiency analyses, waste heat recovery, PV planning, combined heat and power attestation, mobile measurements), Data Science Services (energy monitoring and machine-learning-based load profile analysis), and Business Consulting (subsidies, energy tax refunds, carbon leakage regulation). The company complements these services with two proprietary software products: é.VISOR Cloud, a cloud-based energy data management platform participating in the BMWi 'Einsparzähler' pilot program, and EnPI-Check, a digital tool for DIN ISO 50006 compliance.

The company monetizes primarily through professional services engagements priced on either a lump-sum/fixed-fee basis or a success-based/performance-fee model tied to client savings, alongside recurring software subscriptions for é.VISOR Cloud. With approximately 90 employees across 8 German offices and a cumulative track record of 5,000+ completed projects serving roughly 1,000-2,000 industrial and commercial clients — including named references such as AUDI, Buderus Edelstahl, Faurecia, Ferrero, Aurubis, voestalpine, PERGAN, and Arburg — Limón has positioned itself as a specialized mid-sized consultancy focused on the German Mittelstand and energy-intensive industry. Recognition as a Top 10 Energy Technology Solution Company in Europe (2019, Energy CIO Insights) and BAFA-listed auditor status reinforce its regulatory credibility in the domestic market.
