The project DER-IREC 22@ MICROGRID seeks to implement a microgrid at the facilities of the Catalonia Institute for Energy Research (IREC) in Barcelona. This microgrid is interconnected to Endesa’s distribution network and incorporates electric vehicles as main consumptions.

This report presents the studies and results of activity A431: Analysis of the microgrid regulatory environment, as a part of the work package PT430.

The main objective of the activity has been to analyze the current regulatory framework of the Spanish electricity sector in order to identify those aspects that could be a barrier to the implementation of microgrids and smart grids in general. The results of this paper have been taken into account for the development of the Document 43.2 of the project, were a set of recommendations to the Spanish regulation framework have been introduced.

Also for the realization of this paper the results of work package 410 on the impact on the distribution network and the results of Document 42.1 on the management of the distribution network in a multi-microgrid environment have been considered.

In the first part of the document the description of the current situation regarding the promotion of renewable energies in Spain has been introduced, including the main issues addressed in the PANER 2011-2020. In the second section, linking to the previous chapter, a description of the future of the regulatory framework for the promotion of distributed generation has been included. For this particular issue the draft Royal Decree regulating connection to the network of production facilities of small power has been described. For the analysis of the draft Royal Decree, the changes have been classified as follows: interconnection of distributed energy resources; electricity production and associated economic regime; and the activity of electricity distribution. These regulatory domains are the ones which are used in the third section for analyzing the legal and regulatory framework in relation to the microgrid concept.

In conclusion, it appears that current regulations are intended to advance the deployment of distributed generation, and start in some ways the introduction of the microgrid concept. However for the deployment of microgrid concept, as it is conceived in this project, there would still be other aspects of the regulation that would require revision.
