Net Metering

Last updated: 9 December 2014

Since 1 Jan. 2009, AEEG (Decision ARG/elt 74/08, as subsequently amended and supplemented by Decision ARG/elt 186/09) has assigned to GSE the management of the net metering service (scambio sul posto). This service is activated at the request of interested parties. Under the service, the electricity generated by a consumer/producer in an eligible on-site plant and injected into the grid can be used to offset the electricity withdrawn from the grid. GSE pays a contribution to the customer based on injections and withdrawals of electricity in a given calendar year and on their respective market values.

Under AEEG’s Decision ARG/elt 74/08, GSE has the role of managing net metering and paying the related contribution, which covers part of the charges incurred by the customer for withdrawing electricity from the grid. GSE determines the contribution taking into account: the characteristics of the plant, the contractual conditions between the customer and his/her supplier and  the data that grid operators and suppliers are required to periodically report to GSE. To know more about the calculation of the net metering contribution, refer to AEEG’s Decision ARG/elt 74/08.

 

Eligible plants:

Owners of one or more of the following plants may apply for the net metering support:

  • RES-E plants with a capacity of up to 20 kW;
  • RES-E plants with a capacity of up to 200 kW (commissioned after 31 Dec. 2007);
  • high-efficiency CHP plants  with a capacity of up to 200 kW.
