Grid-Scale Energy Storage Solutions Grid-scale storage enables development of double-digit levels of wind penetration Europe integrates variable energy with big transmission, conventional hydro, and carbon-free pumped storage Changing US market for system reserves and grid reliability services
Ancillary Services: Demonstrating Hydro’s Flexible Generation Flexible Hydropower Is a Proven and Widespread Technology!
Denmark & Grid Reliability 30% wind penetration in the generation mix No native load balancing Balancing services provided via interconnects: - Strong interconnections with Norway, Sweden, and Germany - Utilizes energy storage and flexible energy options in neighboring balancing areas - Excess wind is exported and stored in Norwegian hydropower reservoirs
