Ence Energía y Celulosa, S.A. simply known as Ence, is a Spanish multinational company that develops and supplies technologies, automation systems and services for the pulp, paper and energy industries. The production of paper pulp at its factories in Pontevedra and Navia makes it the European leader in the manufacture of eucalyptus cellulose. Ence is also the leading Spanish company in the production of renewable energy with biomass agroforestry. It generates energy from its plants in Huelva, Mérida, Ciudad Real, Jaén and Lucena. In addition, until November 2020 it also produced solar thermal energy through its 50 megawatt Termollano plant, located in the town of Puertollano, which was subsequently sold. Ence is also the main private forest manager in Spain. Between 1950 and its listing on the Madrid Stock Exchange in 1990, it was a publicly-owned company linked to the former Instituto Nacional de Industria. It was formerly called the "Compañía Nacional de Celulosa". It changed its name to Grupo Ence after its initial public offering in 1990. Firstly, 49% was privatized, and in 2001 the remaining 51%.
