Back in operation

On 26 June 2012 unit C was officially opened. For economic reasons it was mothballed on 1 July 2014. Due to increasing demand for controllable capacity and the positive trends on the wholesale market, RWE decided on 10 October 2018 to put Claus C back into operation. This means that the power plant will be available again for the electricity grid from the end of 2020 onwards.

RWE is planning to build a similar plant adjacent to unit C. The company was granted the relevant approvals in 2016. However, as a result of the difficult economic outlook for natural-gas-fired power plants, there are currently no concrete plans to build the unit. 

Claus was named after Prince Claus of the Netherlands, who officially opened the plant in 1978.

Claus C power plant unit 

Claus power plant's unit C is a "STEG" unit with one steam and several gas turbines. At the power plant there are three gas turbine generators and the steam turbine generator from the old unit B, which is being re-used. The process of generating electricity starts with combusting natural gas in the gas turbines. The combustion gases expand in the turbine, which then drives a generator that produces electricity. The hot flue gases from the three gas turbines heat water in three flue gas boilers, which then turns into steam. This steam sets the steam turbine in motion and this in turn ensures that the connected generator starts to produce electricity. The steam that can no longer be used for generating power at the end of this process is cooled down and turned into water again, which can be re-used.

Linne hydroelectric power plant

The Linne hydroelectric power plant with a capacity of 11 MW is located just a few kilometres away from Claus power plant. The power plant has four Kaplan water turbines and produces enough green electricity for approximately 9,000 households. A fish ladder and a fish bypass have been installed for migratory fish species.
