What EWR does

EWR AG is a regional energy and infrastructure company headquartered in Worms, Germany, founded in 1911. The company supplies electricity, gas, water, and internet/telecommunications services to residential, commercial, industrial, and municipal customers across the Rheinhessen region and adjacent areas in southern Hesse, with grid operations conducted through its wholly-owned subsidiary EWR Netz GmbH. EWR has transitioned from a traditional utility to an integrated energy transition company, evidenced by the acquisition of a 90% stake in SILITHIUM smart energy GmbH in December 2022 (a leading solar installer with ~120 employees) and the acquisition of Elektro Knies GmbH for e-mobility installation services.

The product portfolio combines core utility services (Herzstrom certified green electricity, gas, Wasser water, Herznet DSL/internet) with the EWR One ecosystem of integrated home energy solutions covering photovoltaics, heat pumps, battery storage, wallboxes, air conditioning, and energy management. The platform is supported by digital tools including the EWR Connect customer app and the EWR One Manager app (launched May 2025), which provides AI-based PV forecasting and dynamic tariff optimization, plus the EWR Plus bonus program. The company also operates the EWR-Crowd crowdfunding platform, which has funded 113 community projects with over €508,000 raised. Operational assets include 1,771 kWp of installed large-scale PV, wind parks capable of supplying ~21,210 households, and a 10 MW / 22.8 MWh battery storage project (Speicherpark Holzhof, under construction) — the largest in the Rheinhessen region.

Revenue is generated through a hybrid model: recurring subscription billing for electricity, gas, water, and internet; one-time hardware sales and installation for EWR One products; multi-year Herzwärme+ heat contracting (10-15 year terms); THG-Quota premiums for EV owners; and a growing share of grid services. Go-to-market combines 7 physical customer centers (Worms, Alzey, Kirchheimbolanden, Nieder-Olm, Lampertheim, Bensheim) plus the EWR One showroom, direct field sales for commercial and municipal accounts, online self-service through kundenportal.ewr.de, and certified partner channels (SILITHIUM for PV, Elektro Knies for wallboxes, clever-PV for the energy management app). The EWR-Kommunalforum association encompasses ~80 member municipalities, and EWR's operations are credited with circulating ~€113 million annually into the regional economy, directly and indirectly supporting more than 1,500 people.
