Diemen 34 power plant
Nuon is developing a new gas-fired combined heat and power plant at its existing site in Diemen: Diemen 34. This power plant can produce both heating and electricity. By investing in new environmentally friendly production capacity Nuon can continue to supply electricity and heating sustainably to its customers.
Nuon has chosen to build the new gas-fired plant at its existing site in Diemen because of its location. Diemen is the ideal location because of its proximity to customers with a demand for heating and because of the existence of a heating network. In addition, the site already has the infrastructure needed for a power plant: connections, cooling water capacity, official designation for 'energy production' and room to construct new buildings.
The gas-fired power plant will be a CCGT plant (Combined Cycle Gas Turbine). This technology offers high output (at least 59%) so it is very environmentally friendly. The new power plant will have a maximum capacity of 435 megawatts. This is enough to provide power to 750,000 households.
Additionally, the new power plant will be capable of producing up to 260 megawatts of heating. This raises the output to a maximum of 85%; around 25,000 households can be supplied with heating.
Needless to say, the new combined heat and power plant meets all the statutory conditions, including the emission and noise insulation standards. Nuon has used a tender procedure to select Siemens as contractor to construct the power plant.
The investment decision was taken in August 2010. Since the end of 2012 the plant is operational.
