History

A further waterwheel powers four Hollander beaters. The first boiler with a factory chimney is built. Steam is needed for the drying cylinder.

All waterwheels are gradually replaced by turbines. An approx. 40-meter-high drop in the river Rench is used.

A coal-fired power plant – which operates on the circulating fluidized bed principle and, thanks its CHP technology, reaches efficiency levels of up to 89 % – is built in Oberkirch.

The biomass cogeneration plant achieves a saving of approx. 82,000 metric tons of CO₂ per annum.

The commissioning of biomass cogeneration plant II leads to a further annual saving of approx. 32,000 metric tons of CO₂.

Based on its own in-house energy supply, the Koehler Group has developed a business model for others. Within a short space of time, Koehler Renewable Energy grows the production of power and process steam, etc. into a significant line of business.

• Acquisition of the remaining shares in B E B Bio Energie Baden GmbH in Kehl (sole shareholder).
  
• Operator of, and majority shareholder in, GBE – Gocher Bioenergie GmbH, which saves approx. 35,000 metric tons of CO₂ per annum.
• Shareholder in BEBC – Bioenergie Brunsbüttel Contracting GmbH & Co KG. This biomass cogeneration plant leads to an annual saving of approx. 35,000 metric tons of CO₂.
• Sealing of a partnership with vento ludens for the development of joint wind, hydroelectric, and photovoltaic projects in the UK and Ireland.
  

• DIN EN ISO 50001:2011 certification achieved for the first time at the biomass cogeneration plants of B E B and GBE.
• Takeover of the biomass cogeneration plant WBE – Wiesmoorer Bioenergie GmbH, which achieves an annual CO₂ saving of approx. 17,000 metric tons.
• A further biomass cogeneration plant goes into operation in Elsfleth. KRE is the operator of, and majority shareholder in, EBE - Elsflether Bioenergie GmbH, which results in an annual saving of approx. 35,000 metric tons of CO₂.
• Investment in vento ludens Ltd. for the joint development of projects in the UK.
  

Six wind turbines are erected under the banner of Edintore Windfarm Ltd.

The biomass cogeneration plant in Dollbergen, which was planned on the basis of the German Renewable Energy Sources Act (EEG 2017), costs €40 million and generates approx. 67,860 megawatt-hours of power.

On July 11, 2020, Dollbergen Bioenergie GmbH was able to feed the first electricity produced into the public grid. Natural wood is burned, which simultaneously generates electricity and process steam using cogeneration technology.

Completion and commissioning of four more hydropower plants in Scotland in cooperation with Vento Ludens. Koehler Renewable Energy UK takes over asset management for the total of six hydropower plants in Scotland. The four run-of-river power plants generate enough electricity to supply more than 2,800 average British households.

Koehler Renewable Energy has been represented by its own company in Dundee (Scotland) since September 2021, for project development and asset management. With this move, Koehler Renewable Energy is expanding its activities in other European countries and focusing on onshore wind and hydropower projects in the UK.
