The Neudorf-Werndorf district heating power station near the town of Werndorf is a two-block thermal power station . Block 1 was commissioned in 1968 with an output of 110 MW , and Block 2 followed in 1975 with an output of 164 MW. Unit 1 has been out of service since 2003. Heavy fuel oil is predominantly used as fuel , but natural gas can be used as an alternative . The Neudorf-Werndorf power plant uses a guyed chimney 175 m high.
The power plant was owned by STEWEAG (today STEWEAG-STEG, subsidiary of Energie Steiermark ) until 2002 and became the property of Verbund VTP as part of the South Pole Agreement .
In May 2014, the association decided to close the Neudorf-Werndorf district heating power station together with the Dürnrohr power station and to temporarily shut down the Mellach gas and steam power station . [obsolete] The demolition began in July 2017.
Location
The power plant is located in the greater Graz area and was built by what was then STEWEAG (Steirische Wasserkraft und Elektrizitäts AG) as a potential power supply for the region, mainly to cover the load in the winter months due to the lower yield of the hydropower plants. Until then, a large amount of energy had to be purchased from the Verbund group at great cost in winter. In addition, since the nuclear phase-out decided in 2011, the old block has served as a cold reserve power plant for the German power grid, which means that high-priced, exchange-traded peak electricity can be produced.
In view of the planned refinery in Lannach in the 1960s and the resulting short transport routes, costs and storage capacity, the decision was made to use heavy fuel oil. Due to the long delays in the construction of the refinery, which ultimately did not materialize, a large tank farm with a capacity of 100,000 tons had to be built, which corresponded to the consumption of a period (October to April). The fuel is mainly supplied by rail (90%), the rest is delivered by truck.
Block 1
Block 1 was built in the years 1966-68 with an electrical output ( bottleneck output ) of 110 MW. In 1992 the system was expanded to include district heating extraction with an output of 176 MW.
Fuel use
- 1968–1978: Operation with heavy fuel oil
- 1978–1989: After connection to the natural gas network, combined oil / gas operation
- 1989–2003: By converting the burner and boiler system, pure gas operation and emergency fuel heating oil extra light
- 2003 to today: Preserved
Environmental measures
This block did not have any flue gas cleaning systems until the end of its use . In order to reduce emissions nonetheless, more and more natural gas was used as a fuel (primary measure), from 1989 onwards, Schwer heating oil was completely dispensed with.
Block 2
Due to the rapidly increasing demand for electrical energy, planning for a second unit began shortly after Unit 1 was commissioned. Here, too, the decision to use heating oil as a fuel was difficult and, in the course of the expansion, the tank farm was expanded by a further 100,000 tons. The burners were chosen accordingly with regard to the supply of natural gas. The plant went into operation in autumn 1975 with an electrical output of 164 MW.
Fuel use
- 1975–1976: Heavy fuel oil
- 1976–1988: After connection to the natural gas network, combined oil / gas operation
- 1988-1995: Conserved
- 1995–1997: Conversion: Installation of flue gas cleaning systems to reduce emissions
- 1997 until today: combined oil / gas operation
Environmental measures
In the years 1995 to 1997 a remediation process for better environmental compatibility was carried out. There were denitrification , wet electrostatic precipitators and flue gas desulphurisation plant built at a cost of about 80 million euros. The resulting waste such as gypsum and ARA (exhaust gas cleaning system) cake can be completely recycled as valuable materials in the building materials industry. Furthermore, district heating was also extracted .
