New Approach To Managing Electricity Grid Capacity

Portugal introduces new mechanisms to enhance flexibility in renewable energy grid capacity allocation, allowing technology changes, capacity splits, and regulated assignments. The decree-law creates pathways for optimizing injection capacity through hybridization, aggregation, and exchange mechanisms, though implementation faces technical assessment challenges and interpretative uncertainties.

The diploma aims to increase flexibility and optimize the use of allocated injection capacity in the RESP.

This diploma aims to create and regulate a set of mechanisms for the amendment of reserve capacity titles ("TRCs"), complementing Decree-Law No. 15/2022, of 14 January, as amended ("DL 15/2022").

Rationale and objectives

As stated in the preamble, the diploma arises to overcome the limitations of DL 15/2022 regarding flexibility, optimisation, and reconfiguration of allocated capacity for injection into the public electricity service grid ("RESP").

The objective of the diploma is to expand the range of options available to interested parties to ensure that they effectively use the grid capacity allocated to them, successfully developing their projects, while promoting a more dynamic and efficient management of the grid injection capacity.
