EMILIO ENCINAS

Chairman and founder

Emilio Encinas Román is a businessman with strategic, leadership and creative skills who, back in the 1980s, envisioned a promising future for the then incipient telecommunications sector in Spain.

In 1985, Emilio Encinas founded ZENER based on his entrepreneurial spirit and training in the field of electronics. The company began to install and maintain satellite telecommunications equipment, as well as deploying repeaters and radio links for the implementation of the television signal distribution network.

Over the years at the helm of the organisation, he has turned ZENER into one of the leading telecommunications infrastructure service contractors in Spain, with a diversified portfolio of highly renowned multinational clients and business lines that have expanded into the sector of renewable energies and other areas.

Its constant drive to excel has turned ZENER into a multinational company, carrying out projects in more than 12 different international locations and with permanent offices in 5 countries in Europe and Latin America.

His leadership drives ZENER to constantly identify new business opportunities and to bring changes in the organisation with the aim of adapting the company to the challenges that arise, managing them with an approach that guarantees the long-term sustainability of the company.
