For suppliers, the Portal of computerized registers and telematic tenders is active.

Interested economic operators and suppliers must register on the Portal and proceed to apply for registration in the registers. The Portal identifies firms qualified to supply us with works, goods and services and is the channel of communication and information between us and accredited suppliers.
