The System contribution surcharge is the customer´s share in investments in the transmission grid due to new connections or the reinforcement of the transmission or distribution system.
On July 1st 2018 a new grid code regarding the system contribution surcharge for producers and power intensive users connected to the grid was released. The ESA requires the publication of the methodology and calculations on the system contribution surcharge to ensure transparency and equality. The grid code formalizes the methodology that has been used to determine the surcharge.
The grid code was published on July 1st 2018 following confirmation from the Ministry.
