Altbach power station

From Global Energy Monitor
Part of the Global Gas Plant Tracker, a Global Energy Monitor and Center for Media and Democracy project.

Altbach power station, in the state of Baden-Württemberg, Germany, has 1,036 megawatts (MW) of generating capacity (783 MW coal-fired and 253 MW gas-fired).

The Altbach/Deizisau, Stuttgart-Münster, and Stuttgart-Gaisburg plants together form the Mittlerer Neckar district heating network.

Background

The first power plant in Altbach was built in 1899. In the late 1940s, the forerunner of today's power plant was built. In 1950, Block 1 went into operation. Block 2 and 3 followed in 1960, block 4 in 1971. Block 1 was shut down in 1982 and demolished in 1985. Blocks 2 and 3 were demolished in 1993.[1][2]

Existing power plant

CHP plant 1

HKW 1 was added to the grid in mid-1985. Originally, this facility was called Block 5. The power plant initially had a gross electrical output of 420 MW. By retrofitting the high and low pressure turbine in 2006, the electric power was increased to 433 MW. The district heating output of 280 MW th remained unchanged.[2]

On February 27, 2017, the Executive Board [1] announced that EnBW intended to shut down the block. Since July 5, 2017, the power plant has been in reserve and must be kept operational until 31 March 2020.[2]

CHP plant 2 with gas turbine E

HKW 2 started operation in 1997. It initially had a gross capacity of 336 MW. With a modernization in 2012, the capacity was increased to 350 MW. Hard coal or natural gas is used as fuel for the main boiler.[2]

In addition, HKW 2 has a gas turbine (gas turbine E) with a capacity of 68 MW and a waste heat boiler. The combined electrical power is 428 MW. Like in HKW 1, there is also the option of district heating extraction of 280 MW th in the main boiler operation, which can be increased by a further 87 MW th in co-operation with the waste heat boiler.[2]

Combination block 4 with gas turbine A

Block 4 went into operation in 1972. It has a pilot gas turbine (gas turbine A) type Siemens V93.0 with a capacity of 53 MW and a main oil fired turbine with oil / natural gas boiler with steam turbine. In addition, there is the possibility of directing the exhaust gases of the gas turbine in the main boiler, which allows a combined cycle operation. The electric power is then 238 MW, and in a combined heat and power mode a maximum of 175 MW el and 180 MW th are possible.[2]

The combination block 4 is in cold reserve.[2]

Gas turbines B and C

The two gas turbines went into operation in 1974 and 1976 and have an electrical output of 60 and 85 MW and can be operated either with natural gas or fuel oil.[2]

New gas plant

According to EnBW, given the infrastructure connection of Altbach, building a new gas-fired power plant at the location "is not unlikely."[3]
