Boitzenburger Land

The full-service package

With a capacity of 180.3 megawatts spread across some 170 hectares, this solar farm in the Uckermark region is one of the largest photovoltaic (PV) projects in Germany. It generates roughly 198 gigawatt-hours of zero-carbon electricity a year, enough to meet the annual needs of about 64,000 homes, meaning that the farm saves around 90,000 tonnes of CO2 a year.


GP JOULE built the system in just eleven months under an engineering, procurement and construction (EPC) contract and, in its capacity as general contractor, was responsible for the following:


  • Designing the system, including soil and structural surveys
  • Procuring all system components
  • Building the PV system without any hitches and on schedule
  • Constructing the transformer station
  • Setting up the substations
  • Laying the medium-voltage line to the grid connection point
  • Connecting up to the grid
  • Going on stream and feeding into the high-voltage grid


The system is owned and operated by SEBG Energiepark GmbH. Its principal shareholders are Solarenergie Boitzenburger Land GmbH, run by local farmer Dietrich Twietmeyer (project planner), and Mainova AG, which sells the electricity under a power purchase agreement (PPA).

Ove Petersen

CEO and Co-Founder of GP JOULE

“The project shows what can be done when everyone involved in the project is pulling together as equal partners. Although a farm of this size naturally poses some huge challenges, our EPC team were able to overcome them in a targeted way with the help of the client, the local authorities, our subcontractors and our suppliers. It is this approach, based 100% on the idea of partnership, that characterises us and our most impressive projects.”
