Enhancing Electric Grid Flexibility and Resilience through Strategic Regulation and Innovation
Joan Groizard emphasises that Spains renewable energy potential has become highly attractive for industries and data centres seeking cost-effective green power. He explains that the current electricity grid was built to accommodate demand peaks from prior decades, and despite recent investment, an overbooking of connection requests now strains system capacity.
Recent plans aim to modernise grid infrastructure with a historic investment of over 13 billion euros, focusing on flexible access, security, and demand balance. Regulating large demands through dynamic behavioural criteria helps prevent capacity drain caused by new electronic loads like data centres and electrolysers, which behave differently than traditional consumers.
Spain is also progressing on flexible network access proposed by the CNMC, which enables utilisation of underused capacity by allowing variable and off-peak usage. This approach, demonstrated in other countries such as the Netherlands, could unlock gigawatts of additional demand capacity, reducing congestion and fostering competition.
Measures to prevent speculative hoarding of connection permits include mandating expiry dates and activity-specific authorisations to minimise market distortion. These regulatory initiatives are complemented by ongoing public consultations and prioritised connection points for critical sectors like housing and industry.
Regarding future grid capacity, several tenders are underway for interconnection projects, green hydrogen hubs, and renewable projects, with expectations to announce new capacity auctions soon. Groizard highlights the importance of European-wide coordination, noting that projects like H2Med are integral parts of the interconnected European energy system, rather than solely national ventures.
He addresses concerns about nuclear energy, affirming that current nuclear plants do not meet the demands of dynamic voltage control associated with recent grid issues. Instead, investments are directed towards fast-reacting solutions like grid reinforcements and storage. Spains strategy is to phase out nuclear plants as scheduled, prioritising renewables, storage, and infrastructure upgrades to ensure reliable, clean power supply.
Groizard underscores the importance of reducing reliance on imported fossil fuels, especially from geopolitically uncertain sources such as Russia. The Spanish energy transition aims to slash external dependency from over 70 percent to 50 percent by 2030 through renewables, diversification, and strategic raw materials planning.
He promotes the utilisation of biogases and biofuels, tapping into the agricultural residues and waste streams generated domestically, to enhance renewable integration and waste management. Future plans include developing green hydrogen and renewable gas projects across the islands and mainland.
Concluding, Groizard emphasises the need for collaborative effort, innovation, and swift policy implementation to maximise the opportunities of the energy transition, turning challenges into strategic advantages for Spain and Europe.
