Reflecting on RESTORE 1 Achievements
The first phase of the RESTORE program concluded in April 2025 with remarkable results:
82 standalone energy storage projects selected
Total investment: approximately 115 million BGN (€59 million)
Total available storage capacity: 9,712.89 MWh, significantly exceeding the original 3GWh target
These projects, operating primarily as independent facilities, are designed to provide grid peak shaving and system flexibility, creating a stronger foundation for large-scale renewable energy integration.
