The new energy center of the Győr site is situated between the large area of new buildings and the engine factory. It covers a ground area of nearly 7,000 square meters and supplies the plant with electricity, heat and cooling, as well as compressed air and drinking, cooling and process water. In addition, the plant can receive remote heat from an external source.
The heart of the energy center is a gas power plant with three large boilers, each with a power output of 26 megawatts. An additional combined heat and power plant, which uses a low-emission gas engine to generate electricity, supplies up to 2.7 megawatts of both electrical and thermal energy. The generators have a high efficiency of over 90 percent and can supply more than 5,000 households with heating energy.
All components in the energy center are designed for maximum efficiency. The waste heat of the air compressors for example is recovered and stored in the heat network; this adds up to about 3,500 megawatt hours of thermal energy each year, avoiding 1,000 tons of carbon-dioxide emissions. In the cooling processes, in combination with a free-cooling system, approximately 880 megawatt hours of electricity are saved each year. All supply lines for electricity, gas, water, air and compressed air are optimized for short distances and minimal losses.
For the supply of water, the plant has its own well with a depth of 380 meters. Waste water flows into the municipal sewage treatment plant, but the waste water from the paint shop first undergoes chemical and physical cleaning at the plant. Energy-efficient LED lamps are used for the factory’s exterior and safety lighting; compared with conventional lamps, they achieve annual energy savings of about 300 megawatt hours.
