Power generation
Striking features of the new SGT-
include its efficiency and ecofriendliness,
combined with high availability and
reli ability. The turbine has an electrical
efficiency of . % and achieves an
efficiency of . % when used as a
mecha nical drive. When exhaust heat
is used in a combined heat and power
system, fuel efficiency can be as high
as  %.

Experts are predicting that the demand for electricity
will grow twice as fast as the global population, surging
around 60% by the year 2030. Since resources are scarce,
power generation will increasingly require highly effi-
cient, customized solutions – just like the ones offered
by our flexible and small gas turbines. These gas tur-
bines help secure a stable energy supply since they’re
well suited for decentralized applications. Thanks to
decades of experience in the manufacture of gas tur-
bines, we’re ideally positioned in this dynamic growth
market, drawing upon extensive expertise to support
customers worldwide.
Decentralized energy supply made reliable
Gas-fired power plants are considered an ideal supplement to renewable energy
sources because they’re available at short notice when the wind isn’t blowing or
the sun isn’t shining.
Decentralized energy supplies play a key role in an intelligent power mix. An
increasing number of companies maintain their own power plants that, using a
combined heat and power system, supply valuable process heat that can be used
in manufacturing or for building services – all at competitive electricity prices.
Our portfolio of gas turbines is already ideally tailored to meet the needs of this
market environment. Models with a capacity of 5 to 400 megawatts cover a broad
spectrum of applications and ensure efficiency, reliability, flexibility and environ-
mental compatibility. Low lifecycle costs and high profitability round off this
positive picture.
Our acquisition of Rolls-Royce’s aero-derivative gas turbines business will close
an important gap in our portfolio. Originally developed for use in aviation, the
gas turbines from Rolls-Royce feature an efficient, compact and weight-optimized
design. This makes them particularly attractive for energy supplies in the oil and
gas industry. They’re also used in decentralized power supplies because they can
start up very quickly when needed and rapidly generate power. These advantages
are particularly useful for managing energy peaks or power reserves for industry
or for stabilizing power grids. As a result, we’re expanding our access to the
attractive market of flexible and small gas turbines. We expect high growth poten-
tial in this market in the years to come.
