46 MW biomass plant in Spain begins final testing phase

By Erin Voegele | June 21, 2019

A 46-megawatt (MW) biomass power plant under development by Ence Energía y Celulosa S.A. in Huelva, Spain, has begun the final testing phase of its equipment. Commercial startup is expected later this year.

The company noted the project recently hit an important milestone when the line and the main transformer that joins the new installation to the high voltage park were energized in order to connect the plant to the region’s electrical network.

According to information released by Ence, provisional commissioning is underway to test all the facility’s new equipment, including the biomass boiler and steam turbine. This final testing stage will also address auxiliary facilities, such as compressed air systems, cooling towers and electrical and instrumentation systems.

Startup of the 46 MW facility is expected to occur near the end of 2019 will increase the installed capacity of the Ence Huelva energy complex from 91 MW to 137 MW.

The Huelva complex is already home to two biomass power facilities, one with a capacity of 50 MW and the other with a capacity of 41 MW. The existing 50 MW facility began operations in 2012, consumes more than 500,000 tons of biomass annually, and was built according to the best available techniques as recommended by the EU. The new 46 MW plant has also been built with the best available techniques recommended by the EU for the production of energy with biomass.
