Such repowering jobs make it possible to further establish existing websites in an effective way: Modern turbines produce far more electrical power, are quieter and much better satisfy environmental and spatial planning requirements. Streamlined approval treatments are a further benefit.

“Broadening the use of renewable resources is essential to a safe, budget friendly and climate-friendly energy supply in Dortmund. To attain this, we should utilize every suitable site in a smart and accountable way,” says Peter Flosbach, Technical Managing Director of DEW21. “Through repowering, we wish to take wind energy at this tried-and-tested site in the immediate area of TU Dortmund University’s school to a brand-new level. The task signifies our commitment to carrying out the energy transition in our region at eye level with our partners.”

Renewable resource for a sustainable campus

TU Dortmund University’s goal is to produce and utilize more of its own power and heat from regenerative energy in the future, and in this way decrease its reliance on non-renewable energy sources. To this end, the university is in the procedure of installing a wood pellet plant and putting up a ground-mounted photovoltaic system on North School. In addition, the university is forging ahead with the setup of more photovoltaic panels on the roofings of its structures, where appropriate. The planned wind turbine can potentially utilize regenerative energy supplied in your area to change, at some point, all the electrical energy that TU Dortmund University presently produces from natural gas in its own combined heat and power plant on campus.

Teacher Manfred Bayer, President of TU Dortmund University, says: “Our university supports the regional government’s climate policy goals and is participating in the effort ‘Climate-Neutral State Administration in NRW’. The planned wind turbine is a key enabler, allowing us to produce more climate-neutral electrical power and in this way add to the energy shift. I am pleased that we have actually found a regional partner in the shape of DEW21 who is eager to put this task into practice with us.”

Close intermediary with all those involved

Preliminary studies, carried out by the two partners and covering technical, economic and organizational aspects, to name a few things, are the first task predicted by the Letter of Intent (LOI). DEW21 and TU Dortmund University are also exploring the possibility of setting up a joint funding and operating company sometime in the future. The State of North Rhine-Westphalia, represented by BLB NRW (its structure and property management agency), which is likewise associated with the task, owns the sites in concern. Both partners highlight the task’s collaborative method: The LOI is not legally binding, however it highlights their shared determination to accelerate the project in close liaison with all those included.

“AirWin” is among Dortmund’s first wind power tasks. The plant has fed electrical power into the grid considering that 1997 and is a prominent example of the city’s early intro of wind energy. The planned repowering task should continue this success story and adjust it to the requirements of the current energy shift. The existing plant creates 650 megawatt hours (MWh) of electrical energy annually. Once the repowering project is finished, yearly electrical power production of around 10,000 MWh is anticipated. Mathematically, this indicates supplying 3,000 homes with electrical energy rather than 200.
