”New Electricity Age”
Electricity will be the energy source:
most flexible and efficient energy medium
Renewable energy sources,
(solar, wind, hydro, biomass),
“clean” coal, gas, nuclear
Central + decentralized generation
Smart grid as an enabler
Sustainable energy system, environmental awareness

Wind Power – Innovation Highlight:
Hywind – floating offshore wind turbine
ƒ In partnership with StatoilHydro, Siemens erected
he world’s first floating turbine
ƒ Alternative foundations for sites with water depths
greater than 120–700 meters
ƒ Visually less intrusive and having a higher energy
yield due to the strong and constant wind conditions at sea.
Direct drive
ƒ With “Direct Drive,” Siemens is researching whether
gearless turbines can compete with geared turbines.
ƒ Linking the rotor directly to the generator reduces
maintenance effort and increases availability significantly

Smart generation
Coal-fired power plant with a 50 percent efficiency rating
ƒ A steam temperature of about 700 °C
ƒ An efficiency rating of at least 50 percent
ƒ 40 percent less CO2 compared with
today’s global average
ƒ Consumes 40 percent less coal for
the same amount of electricity.
ƒ In 2014 E.ON intends to put a power plant
of this type into operation in Wilhelmshaven.

Smart transmission
HVDC: Long distances – high efficiency and flexibility
ƒ Large amounts of electricity to be transported
efficiently and in an environmentally friendly
manner across long distances.
ƒ The world's most powerful HVDC installation
in China with a transmission capacity
of 5,000 MW and a transmission voltage
of +/– 800 kV.
ƒ Environmentally friendly hydro-power
from generation facilities in Yunnan to
the industrial center of Guangdong,
which is 1,400 kilometers away.
ƒ The first pole of the system went into
operation in December 2009.
