REN - Redes Energéticas Nacionais operates in two major business areas:
• The transmission in very high voltage electricity and overall technical management of the National Electricity System;
• The transport of high-pressure natural gas and overall technical management of the National Natural Gas System, guaranteeing the reception, storage and regasification of LNG and underground storage of natural gas.
REN also operates in the telecommunications business via RENTELECOM, which includes a range of services, such as infrastructure, managed services and consultancy.
The internationalisation of REN's operations is a business that is taking its first steps, and received a new impulse with the entry of strategic international partners (State Grid and Oman Oil) in to the company capital.
