Entso-E's final root cause report on the April 28, 2025 blackout in Spain and Portugal identified systemic failures in voltage control, reactive power management, and regulatory frameworks, with manual disconnections and lack of real-time monitoring contributing to the blackout. The investigation was hindered by incomplete data, particularly from generators below 1 MW. Entso-E issued 22 recommendations to strengthen European grid resilience, focusing on voltage control, oscillatory stability, disconnection behavior, and defense and restoration, including improving reactive power resources, real-time visibility, and harmonizing operating voltage ranges. The article also discusses recommendations for improving small-scale generation, defense, and restoration in the context of climate-related incidents, suggesting adaptive load shedding schemes, better coordination among operators, and standardized data collection frameworks for future investigations.

Portugal’s EDP, Rondo sign PPA for solar-powered industrial heat project
Portugal's EDP and Rondo Energy have partnered to provide zero-emission steam for industrial use through a heat-as-a-service agreement using a 7 MW solar plant and a 100 MWh thermal battery. The project with Central de Cervejas e Bebidas aims to store renewable electricity as high-temperature heat to supply continuous, carbon-free steam, replacing fossil-fuel boilers. This innovative approach of combining renewable energy generation with on-site heat storage could serve as a model for other energy-intensive industries like food and beverage, paper, chemicals, and pharmaceuticals.
