Renewable energies

Lusatia has the potential to develop from a mining region into Germany's green powerhouse. Here and in other regions we are on the way to sustainably expanding renewable energies. The post-mining landscape offers particular opportunities - a vast, contiguous and low-conflict land treasure for the energy transition. Together with our partners, we are seizing the opportunity to realise Germany's largest project pipeline for solar and wind power. Learn more about our existing plants and current projects.

Our new projects

The construction of wind and solar parks is preceded by an intensive phase of project planning, participation and approval. We are currently planning around 1,000 MW of wind and solar power, including the 100 MW Forst-Briesnig II wind farm, Germany's largest floating PV plant, and the Bohrau energy park, one of the largest solar parks in the country with a capacity of 400 MW.

Germany strives for climate neutrality

The energy supply system in Germany is undergoing a fundamental transformation. Renewable energies are becoming the basis of our electricity supply. At the same time, green electricity is also in demand as a fuel for change in other areas of the economy and life - be it in e-cars, heat pumps or for the production of hydrogen. The so-called "sector coupling" of the electricity industry with the areas of heating, transport and industry is also increasing the demand for electricity here.

Through innovative technology combinations, we want to achieve that green electricity is available to us in sufficient quantities, regardless of the time of day and the weather. It is important for us to enable and help shape regional value chains with the expansion of renewable power generation.

Our current projects

Floating PV plants

The planned floating PV plant on the future Cottbuser Ostsee Lake is a project of superlatives. Germany's largest floating PV plant will be built on the largest mining lake to date. The solar modules with a combined capacity of 29 MWpeak will form a floating PV park of around 16 hectares. The total area of the Cottbuser Ostsee Lake will be 1,900 hectares after the end of flooding. The land take is less than one percent of the lake area. This means that the use of floating PV technology can be combined very well with other uses of the lake in the areas of local recreation, tourism and water sports. EP New Energies is responsible for the project planning of the floating PV system.

Size of the plant

up to 16 hectares

Nominal output

approx. 29 MWp planned

Annual generation

approx. 29,000 MWh planned
(corresponds to the annual electricity consumption of 8,250 households)

Planning status at Cottbuser Ostsee

As an innovative green power project, the floating PV system, in combination with other renewable energy systems, fits in well with the city's vision of implementing a holistic mobility and energy supply concept for a CO2-neutral harbour district at Cottbuser Ostsee Lake. At the same time, it can become a building block for CO2-neutral mobility in Cottbus and Lusatia. 

The construction of the plant required the preparation of a development plan by the city of Cottbus. The development plan procedure was conducted with the participation of the public and public interest groups and began with the decision to draw up the plan in June 2021. The successful conclusion was the resolution of the city council meeting in October 2022.

Due to the process of filling the lake with water (flooding), LEAG had made advance preparations in parallel and had begun with the preparation of the building ground. Between November 2021 and June 2022, the still-dry lake bed in the project area was compacted to a depth of 30 metres using vibro-pressure technology. In addition, an underground supporting structure was created and the access road was prepared for the subsequent delivery of the floating bodies and solar modules. 

The building permit for the construction of 34 dolphins (piles) as anchoring system for the future floating PV system was granted in May 2023 and construction work started.

Forst-Briesnig II Wind Farm

The Forst-Briesnig II wind farm is planned on a 320-hectare recultivation area of the Jänschwalde opencast mine. Here, 17 wind turbines with a total capacity of more than 100 MW are planned on future agricultural land.


The planning area

Project area:

  • Spree-Neiße district; town of Forst (Briesnig sub-district) and Peitz municipality (Horno and Heinersbrück sub-districts)
  • designated as an area suitable for wind energy in the former factual sub-regional plan (TRP) for wind energy use of the Lusatia-Spreewald region of 16.06.2016; sub-regional plan currently being redrafted (requirements for project area still met)

Current use:

  • post-mining area of the Jänschwalde open-cast mine being reclaimed for agricultural use
  • five existing turbines of the Forst-Briesnig I wind farm: Senvion, 3.2M122 NES; hub height 139 m; total height 200 m, commissioning: December 2018, owner: LHI Group, formerly ABO Wind

Visualisations of the planned Forst-Briesnig II Wind Farm

As part of the approval procedure for the Forst-Briesnig II wind farm, the impact on the landscape is analysed and assessed on a project-specific basis. Visualisations that make the planned project visible already today help in this process.

The landscape has always been subject to man-made changes. The extent of the impairment is also linked to the subjective perception of each individual. The basic question of what is perceived as beautiful or ugly is difficult to answer. The larger the facilities, the more they come into view. Therefore, a sensitive choice of location for wind turbines is important. Arbitrary planning is ruled out here, as decisions on the respective suitability areas are already made at the regional level. As part of the approval procedure, the change in the landscape is then analysed and assessed on a project-specific basis, including the recreational suitability of the affected area. If necessary, measures are planned to compensate for the encroachment.


Approval procedure

  • in accordance with the Federal Immission Control Act with public participation and environmental impact assessment
  • investigation of all relevant factors influencing the environment and the surrounding communities (including noise, shadow flicker, fire protection, stability, species protection)
  • expertise of external experts and consultants
  • submission of the application for approval to the Brandenburg State Office for the Environment in July 2021
  • approval notice received in June 2023

Added value for communities

  • Brandenburg Wind Power Euro (EUR 10,000 annually and pro rata to the area of neighbouring municipalities within a radius of 3,000 metres)
  • nationwide opportunities under the Renewable Energy Sources Act (EEG 2021)

Altes Kraftwerk Zschornewitz Solar Park

Zschornewitz was once home to one of the oldest power plants in Germany. It went into operation in 1915 and was shut down in 1992. Now electricity is once again being produced at the site on 5 hectares - this time CO2-free. The solarpark has a generation capacity of 4.5 MWp. This means that, in purely mathematical terms, it can supply around 1,150 four-person households with green electricity. The project was planned by EP New Energies. Approval was granted in cooperation with LEAG's specialist departments. Since commissioning in June 2021,  LEAG energy cubes has taken over the electricity marketing.

Roof systems Lübbenau and Cottbus

In 2020, two rooftop PV systems projected by EP New Energies went into operation: On the roof of the Spreewald Conference Centre in Lübbenau, 510 modules have been supplying around 70 megawatt hours of electricity since they went into operation in April. In Cottbus, 456 solar modules on an area of around 746 square metres generate around 125 megawatt hours of electricity per year. The building permit procedure, including static and fire protection inspections, was handled by LEAG's Permits Department. LEAG energy cubes has been responsible for the supervision of both plants since they were commissioned. The technology of the start-up Energiekoppler is also used in both buildings. With their intelligent Swarm Box, consumption and marketing can be optimised.

IAA Böhlen solar park

The 17-megawatt IAA Böhlen solar park was built on the site of a former and partially recultivated industrial tailings management facility near the Lippendorf power plant and went into operation in 2023. 

Boxberg solar park

The Boxberg power plant solar park with a total output of around 25 MWp went into operation at the end of April 2024 on a 23-hectare agricultural recultivation area of the Nochten opencast mine. It will contribute to the power supply by generating up to 26,000 MWh of electricity per year. In future, the Boxberg/Nochten/Reichwalde site will bundle the expansion of renewable energies, large-scale storage facilities and the utilisation of green hydrogen. To this end, we are preparing the largest future centre for the production and energy use of green hydrogen and the large-scale storage of green electricity in eastern Germany, the H2UB Boxberg, at the current Boxberg power plant.
