At the end of 2018, Ence acquired from Iberdrola 90% of Puertollano’s 50 MW thermo-solar plant, Termollano, as the first step in its diversification strategy towards other renewable powers. The plant, which can reach an annual net production of 68 GWh, is the only one of the company that uses this technology to produce energy.

The solar thermal power takes advantage of the sun’s energy, abundant in the La Mancha plateau, to generate electricity. Through a system of plates that capture heat, and with the help of several highly sensitive substances to react with it, the plant manages to generate renewable and sustainable energy.


Biollano 50 MW, hybridization of solar thermal power and generation with biomass

The Termollano plant is located in the vicinity of the new 50 MW biomass generation plant that Ence is building in the town, Biollano, and which will be operational by the end of 2019.

This new generation plant with biomass, which will start operating at the same time as the 46 MW that Ence is building in Huelva, will be able to produce 325 GWh of electricity per year, and like its twin, it will use the most advanced technologies and systems to guarantee a permanent respect for the environment.

The proximity of the solar thermal plant to Biollano will allow Ence to convert a non-manageable renewable asset -which only generates energy during the hours with Sun- into manageable, thanks to the capacity of the biomass to produce energy in a programmable, firm and stable way , and in times of high demand.

A solar thermal plant without salt accumulation generates energy for 1,500 hours a year. With the installation of a biomass boiler, the solar thermal plant can work uninterruptedly at least from 6 in the morning until 12 at night, which are the hours of maximum consumption of electricity. Thus, with the hybridization of thermosolar with generation with biomass, the Ence energy complex in Puertollano will be able to increase the generation of renewable electricity in about 3,800 hours / year of maximum demand.
