The Mellach gas and steam power plant (GDK Mellach) is a combined cycle gas and steam power plant in the Austrian municipality of Fernitz-Mellach , in Styria near Graz . For economic reasons, it is currently (as of February 2017) only used to support the national grid.
location
The power plant is located in the southeast of the combined power plant location , which extends over both banks of the Mur between the villages of Neudorf ob Wildon (west of the Mur) and Dillach (east of the Mur, southern district of Mellachs). In the immediate vicinity are the district heating power plant Mellach (also east of the Mur), the district heating power plant Neudorf-Werndorf (west of the Mur) and in between the run-of-river power plant Mellach an der Mur .
The Mellach gas and steam power plant is the most powerful power plant in Austria. The owner and operator of the power plant is the Austrian Verbund AG . The total electrical output is 838 MW with an efficiency of 59.2%. The CO 2 emissions are approx. 350 g / kWh. A thermal district heating extraction of 400 MW is also possible. Planning started in 2003, construction started in February 2009 and opened in 2011.
With the changed situation on the European electricity market and, in particular, the sharp fall in electricity exchange prices in 2007, the power plant became increasingly unprofitable due to its position in the merit order . In 2014, it was decided to temporarily shut down the facility for an expected 4 to 5 years. The main reason for the falling stock exchange prices was the collapse in prices for emission rights in EU emissions trading , while the expansion of renewable energies , which is considered the main cause of this decline in the public debate, had only a minor effect. The effect of the lower fuel prices and the lower demand for electricity were also rather minor.
The power plant currently serves (as of February 2017) to ensure security of supply on the electricity market.
Technical specifications
The GDK Mellach consists of two jointly constructed and technically practically identical blocks , each with its own chimney . Both blocks contain both a gas turbine and a steam turbine as well as an electricity generator . The nominal output of the power plant blocks is 700 MW thermal and 419 MW electrical, whereby a thermal district heating extraction of 200 MW each via a common district heating pipe is planned to supply the city of Graz . In total, this GDK can deliver up to 838 MW electrically and at the same time up to 400 MW thermally.
