Elia is a Belgian transmission system operator for high-voltage electricity (30,000–380,000 volts), located in Brussels, Belgium. It operates in Belgium and Germany. The company transmits electricity from generators to distribution system operators, which then supply SMEs and homes. Elia also has contracts with major industrial users that directly connect to its high-voltage grid.
Elia's main activities include managing grid infrastructure (maintaining and developing high-voltage installations), managing the electrical system (monitoring flows, maintaining the balance between electricity consumption and generation 24/7, importing and exporting to and from neighbouring countries) and facilitating the market (developing services and mechanisms with a view to developing the electricity market at national and European level). Elia Group also offers consulting and engineering services through a subsidiary Elia Grid International (EGI), founded in 2014.
