  • The country covers an area of approx.

6.5 km²

  • Gibraltar is an overseas territory of the

United Kingdom with self-government

  • Around 35,000 habitants
  • Roughly 1 million tourists during the peak

season

Today’s power generation Gibraltar

  • Total Gibraltar generating

capacity ~60 MW(e)

  • ~40 engines and turbines

between 0,6 and ~5 MW(e), based on diesel fuel

  • Waterport Power Station

site: 15.6 MW(e) (3 x 5.2MW(e))

Future power generation Gibraltar

  • Today’s Expected energy demand between 16

minimum and 42 MW(e) maximum

  • Energy demand is forecast to increase

to approx. 51 MW(e) by 2027

  • Natural gas as main fuel to reduce CO2 emission and

improve CO2 footprint

  • New technology with higher efficiency
  • Move from several small power plants to a new central

power plant

Project framework conditions

On Focus Security of supply

  • 100% independent energy supply leads to high energy

security

  • High equipment dependability with Dual Fuel engines
  • Better economic efficiency due to use of new gas engines

technology

  • To guarantee continuous 41 MW: 3 gas engines, 14.4 MW(e)

each, and 3 dual fuel engines, 13.7 MW(e)

  • Major invest for the new power plant of Gibraltar
  • By the year 2020, 15% of the energy requirement in Gibraltar

must be generated by renewable energy

  • Smaller solar panels and micro-wind turbines are under
  • construction. Further studies on wave and tidal generators or

negotiations are planned

Highlight DF engine

Fuel change over form gas to diesel

  • Quick change over

(QCO) in case of  emergency or  gas supply interruption

  • QCO from gas to

diesel (and vice versa) immediately at any load

  • Even QCO at

100% load has no implication on power output

High equipment dependability in change over at any load
