Electricity is produced in a generator which can be powered in various ways.

Modern power plants use turbines driven by steam, gas, water or wind.

The choice of technology and motive power is determined partly by the available source of energy, including renewable energy, and partly by economic considerations.

ETP Consult works with control and regulation of the power plants, for example in connection with its work in Nuuk in Greenland, where a hydroelectric plant in the fjord Buksefjorden is used as the primary source of electricity.
