Section 3 of 5The Storage Imperative
Energy storage is the key technology enabling high renewable energy penetration. Without storage, grids must perfectly match renewable generation with demand in real-time, leading to significant curtailment of clean energy. Storage provides flexibility by storing excess generation for use when renewables aren't producing.
Different storage technologies offer various combinations of energy density, power capacity, response time, cycle life, and cost. The optimal solution depends on the specific application - from milliseconds of frequency regulation to days of seasonal storage. Modern grids increasingly use hybrid storage systems combining multiple technologies.
Storage Value Proposition
Storage doesn't just store energy - it provides grid services like frequency regulation, voltage support, peak shaving, and renewable firming. These services create multiple revenue streams that improve storage economics.
