Combined cycle

More and more energy is being consumed all the time by new domestic appliances, computers, microwaves, air-conditioning, etc. Our changing lifestyle means that every year the demand for electricity increases and we want to see those energy needs met.

Combined-cycle offers a real solution, since it allows sustainable development for our society by producing that essential electricity at a lower ecological cost, considerably reducing emissions of the gases that cause the greenhouse effect as compared with the fuels used up till now, such as coal or diesel.

Reduction in emissions:

• 50% of CO² emissions
• 100% of SO² emissions
• 80of NOx emissions

A combined-cycle power station using natural gas needs less space than a conventional thermal power station, and therefore the visual impact is reduced.

• Power station housing the gas and steam turbines used to produce electricity.
• Electricity substation for grid connection.
• The power station requires water for cooling. A water inlet takes in as much as is necessary and after use it is returned intact to the sea at a different point. For more information on this subject, go to: www.bahiasdebizkaia.com

Inside the plant, the combined-cycle produces electricity twice over: first by burning natural gas in the gas turbine and then using steam, in the steam turbine. This is the reason why this sort of plant has such high efficiency rates.
