Energy efficiency in power plants

The efficient use of primary energy in the power-generation process makes a decisive contribution toward lowering CO₂ emissions and is a key issue in our power-plant fleet. In CDM/JI projects designed to increase energy efficiency in power plants and reduce CO₂ emissions, we offer our extensive know-how in the construction and operation of power stations of every type.

Raising efficiency by one per cent not only improves a power plant's profitability by one per cent, but also avoids up to 15,000 tons of CO₂e per year at a 200-MW power station.

Examples of measures to improve energy efficiency inpower plants:

• detailed measurements to identify thermal losses;  
• mills and combustion (e.g. online coal-quality control);
• fixing leakages in flue-gas ducts;
• air heaters: overhaul/upgrade;
• turbine: new blading;  
• condenser: overhaul/upgrade;
• cooling tower: new packings;
• raising the steam temperature;
• lowering internal consumption by optimizing operations or exchanging electrical consumers.
