What is the expected project timeline?
The development of a TES facility typically includes:
- 12–18 months for permitting and approvals
- 36–48 months for construction
The exact timeline depends on local regulations, geological conditions, and project-specific requirements.
What is the expected return on investment?
Historical business case analyses indicated a payback period of approximately 11–12 years under the energy market conditions and energy prices available at the time of evaluation. Actual project economics will depend on local energy prices, regulatory conditions, and system utilization.
Are there similar solutions on the market?
There are other thermal energy storage technologies worldwide, including borehole storage systems and underground thermal storage facilities. However, large-scale underground seasonal storage integrated with district heating infrastructure remains relatively uncommon and represents a significant opportunity for future energy systems.
