ESWE BioEnergie

What ESWE BioEnergie does

ESWE BioEnergie GmbH is a Wiesbaden, Germany-based municipal energy project company that operates a single biomass combined heat and power plant (Biomasse-Heizkraftwerk, BMHKW) in the Wiesbaden-Biebrich district. Founded in 2013, the facility commenced commercial operations on December 13, 2013, and is structured as a 90% subsidiary of municipal utility ESWE Versorgungs AG, with the remaining 10% held equally by waste-management firm MBA Wiesbaden GmbH and fuel-processor Knettenbrech + Gurdulic Service GmbH & Co. KG. The company's sole purpose is the energetic recovery of approximately 90,000 tonnes per year of reclaimed wood (Altholz) sourced regionally from the Rhein-Main area.

The BMHKW uses an air-cooled push-grate (Vorschubrost) combustion system operating at 950–1050 °C, with a multi-stage dry flue gas cleaning train (recirculated flue gas + urea injection for primary NOx reduction, Skimmer pre-dedusting, evaporation cooler, conditioned dry sorption for dust/HCl/SO2/heavy metals, and final particulate filtration). Steam from the boiler drives a turbine-generator set that produces an average of 8.6 MW (max 10.5 MW) of electricity, while turbine exhaust feeds a district heating loop delivering an average of 20.2 MW (max 23 MW) of thermal output. The plant runs as a base-load facility with 7,600 full-load hours/year.

The company's revenue model is wholesale-only: approximately 65 million kWh/a of renewable electricity is fed directly into the grid of Stadtwerke Wiesbaden Netz GmbH via a dedicated 2 km 20 kV cable, and approximately 154 million kWh/a of district heating is delivered through heat exchangers to the district heating network of its parent ESWE Versorgungs AG. Combined output covers roughly 4% of Wiesbaden's total heat and electricity demand and approximately 50% of its district heating demand. The operation holds a permit under the Federal Immission Control Act (BImSchG, granted April 13, 2012), complies with the 17th BImSchV ordinance on waste wood combustion, operates 24/7 continuous emissions monitoring, and is ISO 50001-aligned for energy management. The facility employs 15 permanent staff and avoids approximately 94.7 million kg of CO2 emissions annually.

Core offering

ESWE BioEnergie operates a single Biomass Combined Heat and Power Plant (Biomasse-Heizkraftwerk, BMHKW) in Wiesbaden-Biebrich that uses reclaimed wood (Altholz) as fuel. The plant generates approximately 65 million kWh per year of renewable electricity and approximately 154 million kWh per year of district heating through combined heat and power generation, supplying about 4% of Wiesbaden's heat and electricity demand and roughly 50% of its district heating demand.

Product overview

ESWE BioEnergie operates a single unified biomass combined heat and power plant (Biomasse-Heizkraftwerk/BMHKW) as its core product. This facility generates renewable electricity and district heating simultaneously through Kraft-Wärme-Kopplung (CHP), processing approximately 90,000 tonnes of recycled wood annually. The electricity generation module produces up to 10.5 MW (average 8.6 MW) fed into the public grid, while the district heating module delivers up to 23 MW (average 20.2 MW) of thermal energy. The plant operates as a baseload facility with 7,600 full-load hours per year. The company also provides annual emissions reporting services in compliance with German Federal Immission Control regulations.

Products and services

• Biomasse-Heizkraftwerk (BMHKW) — Biomass Combined Heat and Power Plant Combined heat and power plant that burns approximately 90,000 tonnes of reclaimed wood per year using an air-cooled push-grate combustion system, generating renewable electricity and district heating simultaneously for the Wiesbaden municipal grid and ESWE Versorgungs AG district heating network. The plant operates as a baseload facility at 7,600 full-load hours per year with continuous 24/7 emissions monitoring under BImSchG and 17th BImSchV compliance.
• Renewable Electricity Generation (Strom) Renewable electricity generation with average 8.6 MW and maximum 10.5 MW electrical capacity, producing approximately 65 million kWh per year, fed into the municipal 20 kV grid via a 2 km cable under a bilateral offtake arrangement with Stadtwerke Wiesbaden Netz GmbH.
• District Heating (Fernwärme) Supply District heating supply with average 20.2 MW and maximum 23 MW thermal capacity, delivering approximately 154 million kWh per year at 70–100 °C flow temperatures and 10–15 bar pressure through heat exchangers to the ESWE Versorgungs AG district heating network, sufficient to heat around 12,000 single-family homes.

Partnerships

Four partnerships are on record, tiered core and minor.

• ESWE Versorgungs AGcoreStrategic or Co-development PartnerESWE BioEnergie GmbH is a 90% subsidiary of ESWE Versorgungs AG. ESWE Versorgungs AG is the parent company and primary offtake customer, receiving all produced district heating from the BMHKW through its district heating network. ESWE Versorgungs AG is also the parent company providing strategic direction and shareholder governance.
• Knettenbrech + Gurdulic Service GmbH & Co. KGcoreStrategic or Co-development PartnerKnettenbrech + Gurdulic is a 5% shareholder of ESWE BioEnergie GmbH and the neighboring fuel preparation facility. It processes and prepares the majority of the reclaimed wood fuel (sorting, shredding, removal of contaminants) on its adjacent property before delivery to the BMHKW. This proximity minimizes logistics costs and transport distances.
• MBA Wiesbaden GmbHminorStrategic or Co-development PartnerMBA Wiesbaden GmbH (a 5% shareholder of ESWE BioEnergie GmbH) manages waste disposal at the adjacent landfill (ELW/Deponie). Residues from the BMHKW combustion process are disposed of at this facility, benefiting from short transport routes and reducing traffic-related emissions.
• Stadtwerke Wiesbaden Netz GmbHcoreStrategic or Co-development PartnerThe renewable electricity generated by the BMHKW is fed into the general electricity grid of Stadtwerke Wiesbaden Netz GmbH via a dedicated 2 km medium-voltage (20 kV) cable connection. This is the primary offtake channel for the plant's electrical output (approximately 65 million kWh/a).

Scale indicators8 records

Direct peers

• N-ERGIE AG: N-ERGIE operates biomass-fired combined heat and power plants in the Nuremberg/Fürth area, supplying renewable electricity and district heating under municipal-utility ownership — directly comparable in business model, fuel base, and CHP configuration.
• MVV Energie AG: MVV operates the Biomasse-Heizkraftwerk Mannheim, a biomass-fired CHP plant of comparable scale burning recovered wood and organic residues to supply renewable electricity and district heat to the Mannheim grid — closely aligned technology, fuel mix, and offtake model.
• Stadtwerke Augsburg Holding GmbH: Stadtwerke Augsburg operates the Biomassekraftwerk Augsburg, a biomass CHP plant that uses recovered wood to supply renewable electricity to the Augsburg grid and heat to the municipal district heating network — same technology stack, same municipal-utility ownership structure, same output profile.
• SWK Stadtwerke Krefeld AG: SWK operates a biomass-fired CHP plant supplying Krefeld's local district heating network under municipal-utility ownership — closely aligned in scale, fuel base (recovered wood), CHP configuration, and B2B municipal offtake structure.

Regional players

• Wien Energie GmbH: Wien Energie operates biomass and waste-fired CHP plants supplying Vienna's large-scale district heating network (Fernwärme Wien) — closely comparable technology and municipal utility model, but operating primarily in Austria rather than direct German-market competition.
• Mainova AG: Mainova is the Frankfurt municipal energy utility operating waste-to-energy CHP (Müllheizkraftwerk Frankfurt) feeding the Frankfurt grid and district heating network — comparable in primary activity (CHP generation fed into a municipal utility grid) and in its home Rhein-Main geography, even if its fuel base is mixed municipal waste rather than Altholz.

Broad incumbents

• Vattenfall Wärme Berlin GmbH: Vattenfall Wärme Berlin operates the largest urban CHP portfolio in Germany, including biomass and waste-fired facilities feeding Berlin's district heating — overlapping capability and offtake structure but part of a much larger diversified utility portfolio.
• EnBW Energie Baden-Württemberg AG: EnBW operates multiple large biomass and waste-fired CHP facilities including the Heizkraftwerk Stuttgart and Heilbronn, supplying renewable electricity and district heat into municipal grids — overlapping capability set, but as part of a much larger integrated utility portfolio rather than a single-asset specialist.
