What Enni does

ENNI Stadt & Service Niederrhein AöR is a German municipal multi-utility (Stadtwerke) headquartered in Moers, North Rhine-Westphalia, organised as a public-law institution (Anstalt des öffentlichen Rechts) under municipal ownership. The group supplies electricity, natural gas, drinking water, district heating, wastewater/drainage services, and household waste management to roughly 140,000 residents and a broad base of commercial and industrial customers across the Niederrhein region, including Moers, Neukirchen-Vluyn, Rheinberg, Uedem, Rheurdt, and parts of Duisburg. It also operates municipal services (cemeteries, green spaces, street lighting, winter gritting), four swimming and leisure facilities, an indoor ice rink, and event venues through its subsidiaries ENNI Energie & Umwelt Niederrhein GmbH, ENNI Sport & Bäder Niederrhein GmbH, and ENNI Solar GmbH.

The business is anchored on regulated and quasi-regulated physical infrastructure: a 698.1 km water distribution network, a 480 km canal/drainage network, district heating grids fed by waste heat from the Asdonkshof waste disposal centre and a gas-fired heating plant, and four groundwater extraction and treatment facilities with a softening plant operating since 2006. ENNI generates its own renewable power through solar parks (Mühlenfeld, Vinn, Hoschenhof at 6.6 MWp), wind parks (Repelen, Kohlenhuck, plus a stake in offshore Trianel Windpark Borkum II), and biomass/biomethane CHP assets including the Biokraftgesellschaft Moers/Dinslaken mbH joint venture. The digital layer — the enni.kundenportal and the Meine Enni mobile app — supports smart-meter-enabled dynamic tariffs such as enni.flexstrom öko (linked to EPEX SPOT SE hourly prices), while emerging product lines include enni.wärmepumpe heat pumps, enni.sonnenstrom PV systems, wallbox and public EV charging (70+ stations), and a THG-Quote monetisation partnership with carbonify.

Revenue is predominantly recurring and subscription-based, drawn from tariffed energy and water sales, regulated grid fees (enni.netz), waste collection fees scaled to container size and emptying frequency, and hardware/installation revenue from heat pumps, PV systems, and wallboxes, alongside transaction-based revenue from leisure facilities. ENNI is profitable (around €40M on >€430.5M revenue) and employs approximately 600 people across the group. Distribution is omnichannel: direct sales teams for business customers, physical Kundenzentrum locations, the 24/7 customer portal, and the mobile app, supplemented by community events and sponsorships to reinforce regional brand presence.

Core offering

Enni (ENNI Stadt & Service Niederrhein AöR) is a municipal utility company serving the Moers and Niederrhein region of Germany. It supplies electricity and natural gas under multiple tariff products (including dynamic and green tariffs), provides drinking water, operates district heating networks sourced partly from waste heat, and offers waste collection and recycling services. It also sells and installs heat pumps, photovoltaic systems, and EV charging infrastructure, and operates leisure facilities such as swimming baths and an ice skating arena.

Product overview

ENNI is a multi-service energy and municipal infrastructure company operating at the Niederrhein (Moers, Neukirchen-Vluyn, and wider region). Its product portfolio operates as a platform of interconnected utility and civic services rather than a single unified software product. The core platform encompasses energy supply — electricity (enni.basisstrom, enni.flexstrom Öko, enni.heizstrom, enni.baustrom) and natural gas (enni.basisgas) — alongside water supply (enni.trinkwasser) and wastewater management (Entwässerung). This is extended by renewable energy generation (regenerative Projekte including solar parks, wind parks, biomass and biomethane CHP), heating solutions (enni.fernwärme district heating and enni.wärmepumpe heat pump), and electric mobility (E-Mobilität with public charging infrastructure, wallbox installation, and THG-Quote management). The enni.kundenportal and Meine Enni app serve as the digital self-service layer across all products. Complementing the energy and water business are municipal services — waste collection and recycling (Abfallentsorgung, Kreislaufwirtschaftshof, Mülltrennung), cemetery management (Friedhofswesen), green space maintenance (Grünanlagen), street services (Straßendienst, Winterdienst, Beleuchtung), telecommunications for business customers, and leisure facilities (four swimming baths including enni.solimare, enni.eiswelt, and event venues). Grid operations (enni.netz) are operated as a regulated distribution network operator providing non-discriminatory access to all energy suppliers.

Recent moves5 records

Expansion highlights6 records

Regional players

• Mainova: Frankfurt-based municipal utility supplying energy, water, and district heating. Operates in a different geography but exemplifies the German Stadtwerk model with a comparable mix of regulated networks, supply, and municipal services.
• Lechwerke: Regional energy supplier and grid operator in Bavaria with growing renewable generation. Comparable to ENNI as a mid-sized German regional utility combining regulated network operations, energy retail, and renewable investments.

Broad incumbents

• E.ON: One of Europe's largest energy network operators and suppliers; competes with ENNI in retail electricity/gas supply and operates overlapping distribution network assets in Germany. Relevant as the dominant broad incumbent across ENNI's competitive set.
• Stadtwerke Essen: Major Ruhr-area municipal utility offering energy, water, and a broad portfolio of municipal and leisure services. Larger and more diversified than ENNI but built on the same Stadtwerk model, making it a relevant incumbent benchmark.
• RWE: Headquartered in Essen with significant generation and supply operations in the Niederrhein/Ruhr region. Not a direct Stadtwerk, but its large-scale generation portfolio and retail supply business overlap materially with ENNI's renewable generation and supply offerings.

Direct peers

• SWK Stadtwerke Krefeld: Stadtwerke Krefeld AG supplies electricity, gas, water and district heating in the adjacent Krefeld area, with a similar mix of regulated network operations, energy retail, and municipal services — making it a strong structural analog to ENNI.
• Stadtwerke Dinslaken: Neighboring municipal utility already partnered with ENNI via the joint Biokraftgesellschaft Moers/Dinslaken biomass CHP. Directly comparable multi-utility operator in the same Niederrhein service area.
• NEW Niederrhein Energie und Wasser: Municipal utility serving the Niederrhein region with electricity, gas, water and related services. Highly comparable to ENNI in geography, customer base (residential + commercial in Niederrhein), and integrated utility offering, making it the closest direct peer.
• Stadtwerke Düsseldorf: Larger municipal utility operating electricity, gas, water, district heating, and telecom across Düsseldorf. Same regulatory and ownership structure (AöR-equivalent) and very similar multi-utility profile at greater scale.
• Stadtwerke Duisburg: Municipal utility for the neighboring city of Duisburg, where ENNI already serves Rumeln-Kaldenhausen. Comparable scale and integrated portfolio (energy, water, public transport, bathing facilities) make it a directly comparable regional peer.
