Optimization of Pumped Storage Plant (PSP) with Wind-Solar Hybrids – SgurrEnergy

Renewable energy sources like solar power and wind power are crucial for sustainability, but their variable nature often leads to wasted energy and curtailment. Curtailment, which restricts power off-take, remains a persistent challenge for renewable developers.

The intra-hour variability of solar and wind generation strains grid stability, making advanced forecasting, grid management, and energy storage solutions essential. For example, solar generation fluctuates due to shading or cloud cover, while wind depends on speed and direction changes—causing intermittency.

Accurate prediction of intra-hour variability enables better grid balancing, reducing the need for backup generation and improving integration of renewable sources. Similarly, inter-annual variation (year-to-year fluctuations due to seasonal and climate patterns) requires careful planning and tools like energy advisory services and diversified renewable portfolios.

To overcome these challenges, Pumped Hydro Energy Storage (PHES) has emerged as a proven solution. By storing excess renewable energy and releasing it during demand peaks, pumped storage minimizes curtailment and improves renewable penetration.

This method uses surplus power to pump water uphill, creating potential energy. When demand rises, the water is released to generate electricity—offering high efficiency, long lifespan, and large-scale capacity. Moreover, it enhances grid resilience by balancing fluctuations in renewable energy generation.
