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

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
