ACCESS TARIFFS (ATR)
What is the meaning of the acronym ATR?
The acronym ATR stands for “Third-Party Access to the Network” in Spanish. It refers to the permit granted by the distributor to the owner of the supply point so that it can access the network on the free market.
The body responsible for guaranteeing this access is Red Eléctrica de España (REE). It calculates the system’s operating costs that are then covered by access tariffs, which are set by the Ministry of Industry, Trade and Tourism and reviewed periodically.
