District Energy and CHP to meet the energy needs of Munich’s new Werksviertel

Date: 1 June 2016

The new Werksviertel district in Munich (“Factory Area München”) will replace the Kultfabrik (“Cult Factory”) theme park, located behind the Ostbahnhof train station in the east of Munich. Kultfabrik had been built on the former Pfanni food factory grounds, and was home to many events in its 13 years of existence.

“But there’s no reason to mourn it,” writes Vilijam Zufic in TOTALMunich. “On the grounds and the surrounding area a whole new city district will be developed, and culture and clubbing will remain the focus of the area.”

The former Pfanni food factory site will host attractive space for offices, art, commerce and entertainment. For example, at the heart of the Werksviertel is the 22,000 square meter WERK3 (“PLANT 3″), where potatoes were once processed into dumplings. WERK3 is the first of the former industrial buildings that are being put to new use. It has been completely renovated into lofts, offices, artist studios, galleries and flagship stores of renowned fashion brands, as well as a roof garden and plenty of restaurants and cafes, clubs, an area for open air events. Munich’s new concert hall will also be built here.

But the real highlight of the new district will be its energy system.

In a news release, E.ON reports that Bayernwerk Natur, an E.ON subsidiary based in the greater Munich area, will be the energy supplier to the Werksviertel district. With support from E.ON, the area around the former Pfanni factory site will become largely energy self-sufficient.

The project includes an innovative and sustainable design for the supply of heating, cooling and power to the approximately 90,000 square meter development. The new Munich concert hall, that is to be built in the factory district, will also be integrated into this energy supply concept. It will include a large hall with 1,800 seats and a small hall for up to 800 seats.

According to E.ON, for the final stage of the development, an annual heat demand of around 10,000 megawatt hours (MWh), a power requirement of around 12,000 MWh and a cooling requirement of around 2,000 MWh are currently expected. The future energy demand of the concert hall is not included in these calculations.

Since January 1st, 2016, Werk Kraft GmbH has been supplying power to the site. To meet future energy needs, two natural gas-fired combined heat and power plants rated 850 kWe and 1,050 kWth each, three groundwater heat pumps and one absorption refrigeration unit will be installed at the site. In addition to this, one heating grid, one cooling grid and one power grid are to be set up along with some 20 new transformers. These installations will be used to generate up to 80 percent of the power needed onsite and to supply it directly to the residents of the factory district.

In addition the site will also have a central connection to the high-voltage grid operated by Stadtwerke München (SWM). SWM reached a first major energy transition milestone in electricity in 2015. It is producing more green electricity at its own plants than all households and the underground and tram systems in Munich require. Development is also continuing with the SWM Renewable Energies expansion campaign.

According to SWM, “The energy transition will only succeed if power and heat can be generated from renewable sources. Whenever the energy transition is discussed today, the emphasis is nevertheless usually placed on electricity. Heating has been neglected thus far but unjustly so as most energy is consumed in this sector. SWM is adopting an integral approach to the energy transition. It is pursuing ambitious objectives for both power and heating and thus playing a pioneering role.”

“In the new energy world, which is the focus of E.ON’s strategic alignment, the on-site generation and distribution of energy plays an essential role. With our solution for this location in the heart of Munich, we can demonstrate our expertise in providing energy advice and meeting precisely these sorts of customer requirements,” emphasized Ingo Luge, Chairman of the Board of Management at E.ON Deutschland.

For the execution of the project and the day-to-day management of energy supplies, Bayernwerk Natur and OTEC have established the joint company Werk Kraft GmbH. OTEC owns the property of the former Pfanni site, which is at the center of the Werksviertel district. In terms of operation, Werk Kraft GmbH will also be in charge of all energy-related processes such as supply management, market communication, generation, residual energy procurement and billing.
