Such repowering jobs make it possible to more develop existing sites in an efficient method: Modern turbines produce even more electrical energy, are quieter and much better satisfy environmental and spatial preparation requirements. Streamlined approval procedures are a further benefit.

“Expanding making use of renewable resources is essential to a secure, cost effective and climate-friendly energy supply in Dortmund. To achieve this, we need to utilize every ideal site in a smart and accountable way,” says Peter Flosbach, Technical Handling Director of DEW21. “Through repowering, we want to take wind energy at this tried-and-tested site in the instant area of TU Dortmund University’s campus to a brand-new level. The project signifies our dedication to implementing the energy transition in our area at eye level with our partners.”

Renewable energy for a sustainable campus

TU Dortmund University’s goal is to produce and use more of its own power and heat from regenerative energy in the future, and in this method minimize its reliance on non-renewable energy sources. To this end, the university is in the procedure of installing a wood pellet plant and setting up a ground-mounted photovoltaic system on North Campus. In addition, the university is advancing with the installation of additional photovoltaic panels on the roofings of its buildings, where suitable. The planned wind turbine can potentially utilize regenerative energy provided locally to change, at some point, all the electrical power that TU Dortmund University currently produces from gas in its own combined heat and power plant on campus.

Teacher Manfred Bayer, President of TU Dortmund University, states: “Our university supports the regional government’s climate policy objectives and is participating in the initiative ‘Climate-Neutral State Administration in NRW’. The planned wind turbine is a crucial enabler, enabling us to produce more climate-neutral electricity and in this method contribute to the energy transition. I am happy that we have found a regional partner in the shape of DEW21 who is eager to put this task into practice with us.”

Close liaison with all those included

Initial studies, carried out by the 2 partners and covering technical, economic and organizational aspects, among other things, are the first job predicted by the Letter of Intent (LOI). DEW21 and TU Dortmund University are also checking out the possibility of establishing a joint funding and running business sometime in the future. The State of North Rhine-Westphalia, represented by BLB NRW (its structure and real estate management company), which is likewise involved in the task, owns the websites in concern. Both partners highlight the project’s collective approach: The LOI is not legally binding, but it highlights their shared decision to speed up the task in close intermediary with all those included.

“AirWin” is among Dortmund’s very first wind power jobs. The plant has fed electrical power into the grid because 1997 and is a popular example of the city’s early introduction of wind energy. The planned repowering project must continue this success story and adapt it to the requirements of the existing energy transition. The existing plant generates 650 megawatt hours (MWh) of electrical power annually. As soon as the repowering project is finished, annual electrical power production of around 10,000 MWh is expected. Mathematically, this means supplying 3,000 households with electrical power rather than 200.
