The Emsland natural gas power plant is a power plant complex of RWE Power (formerly VEW ) at the Lingen (Ems) location . The plant consists of several blocks that use various technologies to generate electricity from natural gas , primarily for the medium and peak load range. The plant also supplies remote steam, especially for the Lingen fiber works .
The plant is located in the immediate vicinity between the decommissioned Lingen nuclear power plant and the Emsland nuclear power plant , which is still in operation , but is not connected to them in terms of plant technology. In 2016, the operating times of the power plant increased significantly compared to previous years. In addition to the technical improvements made, this is due in particular to the fall in natural gas prices.

Block A: gas turbine power plant
Block A is closed. It was a gas turbine power plant , formerly with a Siemens V93.0 gas turbine with an output of 50 MW el .
Blocks B and C: Combined natural gas blocks
The natural gas combination blocks B and C formed the actual Lingen natural gas power plant and each provided a gross output of 427 MW (net output 410 MW) to cover medium and peak loads. In addition, an output of 74 MW th in the form of process steam could be extracted from both blocks . A special feature is the combination process, in which a gas turbine is connected upstream of the steam generator : The approx. 430 ° C hot exhaust gases from the gas turbine with a volume fraction of approx. 17% residual oxygen flow into a downstream natural gas-fired tower boiler (1 pressure with ZÜ , live steam 535 ° C / 185 bar / 1150 t / h, make Steinmüller ). Each boiler feeds a steam turbine (365 MW el make BBC ). The heat from the combustion air supplied to the boiler by the gas turbine is also used as useful heat in the steam generator and an efficiency of 42% is achieved. This technology was promoted by Klaus Knizia ( CEO of VEW from 1975 to 1992) and implemented from 1972 to 1974 in the Emsland and Gersteinwerk natural gas power plants .
One of the blocks is a natural train - wet cooling tower , which is connected to the Dortmund-Ems Canal . The plant was built by Kraftwerk Union as general contractor and went into operation in 1974/1975.
In 2011 the existing 55 MW gas turbines (Siemens V93.0) were replaced by two new Rolls-Royce Power Systems Trent 60 gas turbines , which increased the output to 475 MW and the efficiency to 46%. In the event of a power failure , the turbines can also be started by diesel generators . In this way they guarantee black start capability .
Block D: Combined cycle power plant with natural gas storage
On September 7, 2010, the new Unit D, a gas and steam combined cycle power plant with a total output of 887 MW, went into commercial operation. The block consists of two gas turbines (make Alstom GT26 , 288 MW) whose exhaust gases are each fed to a waste heat steam generator. The steam generated in this way is fed to a common steam turbine (326 MW); this circuit enables an efficiency of 59.2%. Thanks to the cogeneration of heat and power, up to 100 tons of process steam can be extracted from this block every hour. That means: Part of the steam is diverted from the steam turbine and made available to an industrial customer.
A 123 m high cooling tower was built to remove the physically caused waste heat, which can no longer be used technically. Also to the power plant includes a gas - pipe storage .
Due to the strong turbulence on the energy market, the quick start capability of Unit D had to be improved by converting the system and adapting the control system in order to optimize the economy. The gas turbines can now provide their full output of 540 MW within just 45 minutes, thus guaranteeing supply and network security.
Mains connection
The Vorschaltturbinen of the blocks B and C dine on the 110 kV high voltage level in the distribution of the West Network a. In the transmission system of Amprion the steam turbines of the blocks B and C on the 220 kV feed high voltage level and the block D on the 380 kV high voltage level a. The grid connection is made on all three voltage levels via the switchgear in Hanekenfähr .

B1 | 116 MW | 110 kV | Western network |
B2 | 359 MW | 220 kV | Amprion |
C1 | 116 MW | 110 kV | Western network |
C2 | 359 MW | 220 kV | Amprion |
D. | 887 MW | 380 kV | Amprion |
