What e-werk Sachsenwald does

e-werk Sachsenwald GmbH is a privately held municipal energy utility (kommunaler Stadtwerke) headquartered in Reinbek, Schleswig-Holstein, founded in 1899. The company serves more than 80,000 residents across six Schleswig-Holstein communes — Reinbek, Wentorf bei Hamburg, Glinde, Wohltorf, Oststeinbek, Barsbüttel — plus Aumühle for gas from 2017, acting simultaneously as the regulated electricity and gas distribution-grid operator, the default supplier (Grundversorger in Reinbek, Wentorf and Wohltorf), and a retail energy supplier under the SachsenwaldStrom and SachsenwaldGas product families (including green "natur" tariffs, heat-pump "wärme" electricity, dynamic "dyn" tariffs, and Mieterstrom/rooftop-PV offerings).

Revenue is generated from five streams: retail electricity subscriptions, retail natural-gas subscriptions, regulated network access fees (Netzentgelte) on its electricity and gas grids, e-mobility (31+ public EV charging stations, proprietary charging card, THG-Bonus service, wallbox hardware), and energy services / house-connection works. Distribution combines an on-site customer center in Reinbek, a mobile "Infomobil" advisory unit, an in-home "Zuhause Service" consultation, 24/7 online customer and installer portals, and the "mein e-werk" mobile app launched in 2025.

Technology is centred on the in-house Netzleitstelle (grid control center) in Reinbek and an in-house Tiefbaumannschaft civil-engineering team (since September 2019) supporting house connections, reducing reliance on the tight external construction market. The company holds DVGW TSM and VDE TSM technical-safety certifications, the 2025 Top-Lokalversorger seal for both Strom and Gas, and the Ökostrom renewable-electricity label. Ownership is hybrid and municipal: City of Reinbek, Municipality of Wentorf, Thüga Aktiengesellschaft (Munich) since 1952, and Schleswag Aktiengesellschaft (Rendsburg). Since 1 January 2022, Freizeitbad Reinbek (public leisure pool) has been a wholly owned subsidiary, extending the group beyond pure energy supply. Managing Director since February 2024 is Moritz Manthey, succeeding long-serving Thomas Kanitz.

Scale indicators10 records

Recent moves10 records

Expansion highlights7 records

Others

• Gasag AG: Berlin-based municipal gas and heat utility owned by the State of Berlin; useful structural peer for a municipal-owned multi-utility with gas-network focus navigating the energy transition and decarbonization of heating demand.

Broad incumbents

• Vattenfall Wärme Hamburg GmbH: Large incumbent utility supplying electricity, heat, and gas across the Hamburg metropolitan region; competes with e-werk Sachsenwald for retail customers at the Hamburg-city-limit boundary and operates district-heating/grid assets at substantially greater scale.
• HanseWerk AG: Major northern-German energy network operator (subsidiary of E.ON) operating electricity and gas distribution grids across Schleswig-Holstein and Hamburg; the most likely competitor in any future municipal concession tender and a benchmark for network-operator scale.
• EWE AG: Large regional energy utility headquartered in Oldenburg serving northern Germany (including adjacent Schleswig-Holstein areas) with electricity, gas, telecommunications, and increasingly e-mobility; representative large-scale benchmark and potential concession tender competitor.

Direct peers

• Stadtwerke Norderstedt: Larger but structurally similar municipal utility in Norderstedt (Schleswig-Holstein, just north of Hamburg); operates combined electricity, gas, heat, and water plus e-mobility — a useful scale comparison for e-werk Sachsenwald's multi-utility model.
• Stadtwerke Geesthacht GmbH: Small municipal utility in Geesthacht, Schleswig-Holstein — directly comparable in size, structure, and service area: combined electricity + gas supply for a similar mid-sized town east of Hamburg with own grid operations and retail tariffs.
• Stadtwerke Wedel GmbH: Small municipal utility serving Wedel on the Hamburg western edge with combined electricity, gas, heat, water and grid operations — directly comparable in size, customer mix, and value-added service model.
• Stadtwerke Ahrensburg GmbH: Neighboring municipal utility in Ahrensburg (Stormarn district, Schleswig-Holstein) with very similar profile — electricity and gas retail plus grid operation for a comparable suburban Hamburg-metro community.

Emerging players

• Lichtblick SE: Hamburg-based green-energy and dynamic-tariff specialist; competes with e-werk Sachsenwald for retail customers in the Hamburg metro area via app-based Strom und Wärme products, and is a model for the digital/dynamic-tariff offering (SachsenwaldStrom dyn) that e-werk has just begun to roll out.

Regional players

• Stadtwerke Lübeck GmbH: Regional municipal utility in Lübeck (Schleswig-Holstein) operating combined electricity, gas, heat, water and e-mobility; serves as a useful Schleswig-Holstein regional benchmark for the multi-utility + e-mobility + grid portfolio model that e-werk Sachsenwald is building.
