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

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
