Turning Lisbon’s waste into energy

An ABB variable speed drive solution has reduced the power consumption of the Valorsul waste-to-energy plant in Portugal by 9 megawatt-hours a day, equivalent to a saving of $320,000 a year at current energy prices. Valorsul processes the waste of Lisbon and much of western Portugal into valuable electrical energy, producing enough electricity to power a city of 150,000 inhabitants.

One-fifth of Portugal’s waste is processed and converted into electricity at the Valorsul waste-to-energy plant. Located on the outskirts of Lisbon, the plant recovers the solid waste of 19 municipalities in the capital and western Portugal, and turns it into 50 megawatts of electricity – enough to meet the needs of a large city.

Looking for ways to reduce the energy consumption and CO2 emissions of the plant, Valorsul identified six fans with a high energy saving potential: three induced draft (ID) fans and three secondary air fans.
