Unformatted text preview: s. When several turbines are installed, it is often called
a wind farm. In practice, a wind turbine can utilise up to 40% of the kinetic
energy of the wind that passes across the blades. The maximum
theoretical energy utilisation rate is about 60%.
By the end of 2005, approximately 280 MWh of wind power was
installed in Norway, distributed across 138 turbines. This represents a
production capacity of around 0.85 TWh, which is equivalent to the
electricity consumption of around 40,000 households. Some 507 GWh of
wind power was generated in Norway during 2005. This was nearly double
the previous year’s generation. Report No. 29 to Parliament on energy
policy (1998-99) set a target of building wind power stations with a
generating capacity of 3 TWh by 2010.
Gas-fired power is often used as a general designation for all
facilities that use natural gas to generate electricity and possibly heat.
Several types of gas-fired power plants exist. One in which gas turbines
generate all the electricity is known as a simple-cycle gas turbine station.
Such facilities can be started up and shut down at short notice, and are
therefore suitable for providing pea...
