,
Northern Ireland’s Strangford Lough is home to the
world’s first commercial tidal current power plant.
Since November , two turbines have been produc-
ing a combined output of . megawatts – enough
electricity to meet the needs of , households.
To date, the installation has fed more than five giga-
watt-hours of electrical energy into the grid, making
it the world’s largest tidal turbine project. Further tidal
farms are now in the planning phase: the eight-mega-
watt Kyle Rhea project in Scotland and the ten-mega-
watt Anglesey Skerries project in Wales.
Making renewables
competitive
,
We’re building a record-breaking combined cycle power
plant in Düsseldorf, Germany. Boasting an electrical out-
put of megawatts, the facility will set a new world
record for a single power plant in combined cycle opera-
tion. With a net efficiency of more than %, it will also
surpass the previous world record of .%. And the
plant will set a third record as well: never before has
it been possible to extract megawatts of thermal
energy from a single combined cycle plant for use in
a district heating system.
