Baglan Bay CCGT Power Plant, United Kingdom
A combined-cycle gas turbine (CCGT) power plant in the Baglan
Bay Energy Park isnow generating 525MW. Claimed at the time to be
the most advanced CCGT facility ofits kind, Baglan Bay is a
showcase for General Electric (GE) gas turbines.
The plant cost 300 million. It was built and is being operated
by GE Power Systems.The new power plant was a replacement for a BP
Chemicals facility, which came out ofproduction early in 2004. The
efficiency of the power plant is enhanced through theuse of
district heating to the surrounding area. The Energy Park is
sponsored by BP,the Welsh Development Agency and the Neath Port
Talbot County Borough Council.
H SYSTEM GASTURBINES
GE has installed its H system turbines at the facility. The
world's largest gas turbine(the 9H) is 12m long, 5m in diameter,
weighs 370t and is rated to produce 480MW ofelectricity in combined
cycle operation. The H System provides high efficiencyelectricity
production with low levels of emissions. According to General
Electric, the
efficiency of the turbines is close to 60%, giving savings as
high as 30% on fuel bills.The possible savings in energy are
accentuated by the UK's imposition of a climatechange levy designed
to discourage heavy energy use.
The new power plant has one 9H gas turbine, one steam turbine
and one electricalgenerator (with a nominal capacity of 480MW). The
plant has combined heat andpower (CHP) capability, a heat recovery
steam generator (HRSG), steam supplysystems with additional heat
recovery, black start capability and associated auxiliariessuch as
cooling towers, water treatment plant and back-up steam supplies.
The sitealso includes a GE LM2500 aeroderivative power generation
system capable of blackstarting (i.e. starting with no electrical
input). This is effectively a small, extra powerplant.
POWER PLANT CONSTRUCTION TIMETABLE
The first application to build a power plant at the site was
made in 1996. This wasmade by BP Amoco, and was originally intended
for a 1,100MW CCGT power plant. Thenew facility was approved by the
UK's central government in early 1999. The H Systemwas shipped to
Baglan Bay in December 2000 and was constructed in the
GeneralElectric facility at Greenville, South Carolina. It started
up in 2002, followed bycharacterisation testing through the summer
of 2002 and field testing in November2002. It went commercial
shortly afterwards.
The Baglan Bay project was welcomed by the local authorities for
the amount ofregeneration and employment it brought to the area. It
supplied hundreds of
