Advanced Energy Storage Solutions: Power Electronics and the PCSM Inverter within the ERDF Framework

Spain’s energy transition roadmap has entered an execution phase that demands not only generation capacity but also grid resilience and stability. In this context, the European Union has mobilized European Regional Development Funds (ERDF) as a strategic instrument, with a goal that goes beyond the mere installation of renewables: strengthening a robust European value chain. 

This dual focus on funding tied to local sourcing and advanced technology positions European manufacturers like Power Electronics as the preferred choice, offering project developers a double advantage: compliance with regulations and leading technological performance. 

ERDF Funds: Boosting the European Value Chain 

ERDF funds, managed in Spain by the Spanish Institute for Energy Diversification and Saving (IDAE), aim to incentivize investment in storage technologies that reinforce Europe’s economy and industrial capacity. As a result, the origin of components and technology are key evaluation criteria. In parallel with the growing demand to hybridize operational solar plants, the high flexibility offered by Power Electronics' products makes them the optimal solution for DC coupling through DC/DC converters. 

Power Electronics meets all the requirements necessary for its clients to qualify for the maximum applicable score in the ERDF assessment criteria, simply by choosing proven European technology. This scoring is critical and is broken down into contributions to the battery value chain (PCS power electronics, electrical system and protection, and O&M). 

Grid Forming: The Technology That Maximizes Scoring 

Within the IDAE's innovation and demonstrative character criteria, Grid Forming capability is awarded up to 1 point. This advanced technology allows energy storage inverters not only to follow the grid but also to actively form it and simulate traditional synchronous generators’ behavior. It provides inertia, frequency control, and Black Start Capability following an outage. These features have become a technically necessary and act as essential financing lever in the energy system in Spain. 

For Power Electronics, the PCSM battery inverter is the pivotal equipment in this ecosystem. The PCSM solution is distinguished by its modular design and high power density, which simplify installation and maintenance. Furthermore, its advanced technology is specifically engineered to deliver the most cutting-edge Grid Forming functionalities, ensuring grid stability and resilience under any operating condition. 

From Australia to the Balearic and Canary Islands: Proven Technology 

While many industry players remain in the simulation phase for Grid Forming functionalities, Power Electronics operates with proven technology. The Spanish multinational has been actively engaged for years in mature markets like Australia, where Grid Forming technology is a requirement. 

This international experience translates into large-scale projects on Spanish soil. In the Balearic Islands, Power Electronics has equipped the country's largest battery storage plants located in Mercadal (Menorca) and San Antonio (Ibiza). In collaboration with Red Eléctrica de España, Spain's TSO, these facilities total 200 MW using Grid Forming technology, setting a benchmark in grid resilience and stability. 

Additionally, Power Electronics’ PCSK inverter is part of the ViSync project in the Canary Islands. The storage solution will connect to the high-voltage transmission network of the Lanzarote-Fuerteventura electrical system, operating as an integrated grid asset. Its mission will be to offer a wide range of services to ensure the safe operation of the grid and facilitate greater penetration of renewable energy. The system will feature 16 MW of power (18.8 MVA apparent maximum power) and 3.45 MWh of storage capacity. 

Genera: The Meeting Point for Energy Storage 

Energy storage is consolidating its role as a key element in the energy transition, and projects that integrate Grid Forming technology and solutions aligned with ERDF criteria have a significant competitive advantage. 

Genera, the International Energy and Environment Trade Fair, will take place at IFEMA Madrid from November 18 to 20, 2025. It is the ideal setting to explore the growth of storage, the hybridization of renewable plants, and European funding opportunities. 

Power Electronics will be exhibit at Booth 10D21 – Hall 10, showcasing its solutions for energy storage and electric mobility. In addition to the PCSM battery inverter, the DC/DC converter will be on display, and the E-Mobility division team will present the Standalone NB 400 charger, the NB Station, and the Megawatt Charging System (MCS), designed for high-power applications.
