With solar adoption accelerating across Portugal, the challenge of intermittency has come into sharp focus. High volumes of solar production can lead to grid volatility, negative pricing, and wasted energy. This is where battery energy storage systems (BESS) step in — shifting energy from midday oversupply to evening demand peaks.Portugal is still in the early phases of its energy storage cycle, creating a unique opportunity for first movers. Recent policy changes allow for co-located solar and storage projects under a single regulatory framework. Developers now benefit from shared grid access and faster permitting for hybrid solar-plus-storage facilities.For investors, this shift represents a chance to diversify within the clean energy space while capturing premium valuations on exit. At Solar45, we are advancing a pipeline of BESS-enabled projects that integrate seamlessly into our solar development strategy.Energy storage is no longer a ‘nice to have’ — it’s the backbone of a resilient, profitable energy future.
Santa Marta: Solar Scale and Storage Potential in Southern Portugal
Portugal’s renewable energy transition is increasingly shaped by two connected opportunities: large-scale solar generation and grid-scale battery storage.Santa Marta brings both together. Located in Southern
