“EEQ2” new heating & power station connected to building and district network View
EEQ2 System
The “EEQ2” project is an initiative from the energy provider of the city of Görlitz, SWG. A similar project had already been achieved in 2011, with the construction of an efficient energy district, “EEQ1”. This successful experience led SWG to develop a new project. It was triggered by the need to replace the heating plant in the detention center. Also the heating plants of many of the neighbor buildings had to be replaced. The project then concentrated on winning new customers, the technical conception of the plant, and the adaptation of the project’s characteristics to site. In fact, little place was available, and the safety measures surrounding the detention center were strict. All in all, the construction time only took four months, and the heat delivery to the detention center was assured throughout the works. The power station is composed of three parts. The CHP unit, powered by natural gas, produces yearly 1,431 MWh of electricity and 945 MWh of heat, which represents 53% of the total heat. The remaining heat demand is covered by two condensing gas boilers adding 1,280 MWh per year to the heat injected onto the grid. The last element is the hot water storage unit, which enables to balance supply and demand. Finally the system avoids the emission of 314 tons of CO2 and helps to expend the use of cogeneration. The project also succeeded in adapting itself to the restrictions imposed by the site, and could meet the deadlines and respect the initial budget.
