The Twinerg power plant (also: Esch-sur-Alzette CCGT Power Plant Luxembourg) was a thermal power plant in the municipality of Esch-sur-Alzette in Luxembourg with an installed capacity of 375 MW . It has been out of service since 2016 and is currently being demolished.
history
In the mid-1980s, a first feasibility study for the construction and operation of a gas and steam turbine power plant (CCGT plant) was carried out. In December 1995 concrete steps were taken by the government.
The power plant was built from 1998 by Cegedel , Sotel and Electrabel SA. It was the first thermal power plant to be built in Luxembourg. The European Investment Bank financed the construction of the power plant for the operating company Twinerg SA with 80 million euros. The total cost was assumed to be around 150,000,000 euros (6 billion Luxembourg francs ).
In 2001 Greenpeace protested against the power plant and symbolically installed lines for the non-existent district heating network from the gas and steam turbine (GUD) Twinerg. The activists from Greenpeace were of the view - in historical retrospect, correct - that the Twinerg plant was oversized and inefficient. The same energy output with lower carbon dioxide emissions can be achieved with smaller power plants and there is still no district heating network for utilizing the waste heat.
During the winter months 2015–2016, the power plant was part of the strategic reserve of the Belgian electricity supply system. After that, it was no longer necessary to use it as a reserve power station for the Belgian electricity supply system.
On July 7, 2016, the operator of the Twinerg facility decided to cease commercial operations. and in October 2016 the plant was shut down.
Holdings
The operating company Twinerg SA was 65 percent owned by the Belgian energy group Engie Electrabel, and 17.5 percent each by Enovos Luxembourg and ArcelorMittal Luxembourg.
Technical specifications
The gas power plant was a thermal power plant in Luxembourg. The total installed output was 385 and 375 MW, respectively. The plant has a block of gas turbines. The facility was built from 1998 and completed in 2002. Until 2016, the electrical energy was fed into Sotel's industrial network and thus indirectly into the Belgian transmission network via one of the two 220 kV circuits of the Aubange-NP coupling line.
The originally planned term was 20 years, which was extended to 25 and then to 30 years due to the reduced number of production hours. In fact, the runtime up to the termination from 2017 was only around 14 years.
General
The CO 2 emissions of the power plant amounted to 749,260 tons in 2008.
Electric power plant
- Year of construction 1998
- Commissioning: May 7, 2002
- Opening: November 15, 2002
- Supplier: Alstom
- Type: gas power plant (Combined Cycle Gas Turbine - CCGT) with 9001FA gas turbine cogeneration
- Primary energy carrier: natural gas
- Thermal output: 1 × 385 MW
- Electric power: 375 MW
Combined heat and power
The district heating from the power plant was supplied to the city of Esch-sur-Alzette . The heat was put into operation in 2008 with a total output of 28 MW th that could be extracted , and by 2015 it had reached a maximum total load of 12 MW th for the district heating supply .
The heat output made available was less than 5% of the total heat output that can be extracted from the Twinerg power plant. Due to the shutdown of the industrial CHP plants (CEDUCO, CEGYCO) and the Twinerg, the thermal CHP output in Luxembourg has been greatly reduced.
The district heating network is now supplied with the gas and heating oil fired boilers from the Sudcal district heating network.
environment
On September 8, 2014, when the power plant was started up after a period of standstill for months, a yellowish-brown cloud was emitted, which rained down on the surrounding houses and gardens. A few weeks later, on October 2nd, there was further environmental pollution from the power plant through a cloud of dust. A few months later, on February 3, 2015, another yellowish dust cloud was emitted (probably again nitrogen oxide).
Reasons for shutdown and demolition
The power plant would have the Luxembourg and Belgian electricity systems
- Meeting the demand for electricity (especially at peak times ) and
- Provision of system services
should serve. Since there is currently no demand according to the Luxembourg transmission system operator Creos or the Belgian transmission system operator Elia, the power plant is not relevant to the system. Due to market expectations and the long-term price situation on the electrical energy market, the operation of large power plants, especially on the basis of natural gas, as well as the construction of new power plants in general, is not economical in the current market environment.
This is a tendency in many European countries for gas-fired power plants, which are currently under economic pressure because energy prices are low and there are overcapacities in the market, which means that many gas-fired power plants are barely utilized and only run a few hundred hours per year. The residual value of the Twinerg power plant in the amount of 71.3 million euros was written off in full.

The reserve capacity was necessary because some nuclear power plants in Belgium had to be disconnected from the grid in order to repair microcracks in the concrete shell. The transmission system operator Elia had paid Twinerg 5.7 million euros to keep the Twinerg power plant ready for a year so that it can step in within six and a half hours in an emergency (Michèle Sinner: Verheizt , d'Lëtzebuerger Land, July 15, 2016).
