ALSTOM to build the world's biggest lignite power plant in Germany

ALSTOM has won a 450 million euro contract to build the
worlds biggest lignite fired plant in Neurath, Germany,
for utility RWE Power.

The new Neurath lignite fired power plant, with a net
capacity of 2,100 MW, will include some of the most advanced
steam turbine and generator technology in the world.

Under the contract, ALSTOM will carry out the overall
power plant engineering. ALSTOM will also supply, erection
and commission two steam turbine islands including condensers
and, in consortium with another company, deliver two steam
generators. The work at the building site for the
construction of the double-unit plant started last month.

The Neurath power plant will use advanced technology
resulting in high efficiency and considerably reduced carbon
dioxide emission per kWh, as compared with existing
lignite-fired power plants. The investment is the largest one
decided by the RWE Power Group in power generation and is the
continuation of a successful co-operation between RWE Power
and ALSTOM over many decades.

Philippe Joubert, President of ALSTOMs Power
Turbo-Systems/Power Environment Sector, said:
Reducing CO2 emissions is both an environmental
imperative and a commercial concern for our customers. This
power plant will be one of the benchmarks in Europe for
efficient, clean coal-based power production and we are very
pleased to be chosen by RWE Power to lead this challenging
and important project. 

The ALSTOM-made steam turbines will be the largest in
fossil power plant construction with a gross capacity of
1,100 MW each. They use the most modern generation of blading
with flow-optimised three-dimensional blades and the longest
last-stage blades that have been offered on the world market
up to now. ALSTOM has designed an extremely compact
four-cylinder turbine in this capacity class, which makes a
decisive contribution to the reduction of the construction
costs and thus to the overall efficiency of the power plant.
The associated generator will be the worldwide largest
two-pole generator.

ALSTOM, in consortium with another company, will deliver
two once-through steam generators also with a gross
capacity of 1,100 MW each. They will be the largest
lignite-fired steam generators worldwide with the highest
steam mass flow, with supercritical steam pressure and the
highest steam temperatures ever realised for lignite. Along
with the steam generator size, these supercritical steam
parameters are a particular challenge for the engineering of
the individual components and due to the overall
height for the erection concept of the two
plants.
