This article provides a comprehensive analysis of the Spanish grid codes and connectionprocedures, specifically focusing on Royal Decree 1183/2020 and Royal Decree 647/2020. Itexamines how these regulations facilitate the integration of energy storage systems and Vehicle-to-Grid (V2G) technology into the Spanish electricity grid, crucial for achieving the nation'sambitious renewable energy targets. The article details the administrative streamlining for gridaccess introduced by RD 1183/2020, which treats energy storage facilities akin to generationassets, and elaborates on the technical requirements for Power-Generating Modules (PGMs)outlined in RD 647/2020, transposing European network codes. It discusses the current state ofenergy storage deployment, highlighting challenges in Battery Energy Storage System (BESS)adoption despite strategic targets, and explores the potential, regulatory hurdles, and ongoingpilot projects for V2G integration. The conclusion emphasizes the need for continued regulatoryrefinement, market adaptation, and technological maturation to fully unlock the flexibility andresilience offered by these technologies in Spain's decarbonized energy future.
