Building new pumped hydro storage (PHS) facilities faces several key challenges that can impact their development and implementation:
Main Challenges
-
Environmental and Social Risks:
- Ecological Impact: The construction of reservoirs and dams can alter local ecosystems, affecting water flow and wildlife habitats.
- Community Displacement: Large reservoirs can displace local communities and wildlife, disrupting existing habitats and leading to ecological imbalances.
-
High Initial Costs and Financial Risks:
- Substantial Initial Investment: Setting up a PHS system involves significant costs, including reservoirs, dams, turbines, and generators, which can be a barrier for new projects.
- Lack of Bankable Revenue Streams: PHS projects often lack clear, predictable revenue streams, making them less attractive to private investors.
-
Geographical and Technical Limitations:
- Site Suitability: Finding suitable locations with adequate elevation differences is crucial, limiting where PHS facilities can be built.
- Technological Scalability: Scaling up PHS systems to meet increasing energy demands requires significant infrastructure investments and can be complex due to technological limitations.
-
Regulatory and Licensing Challenges:
- Long Development Time: Projects take many years to develop due to lengthy regulatory processes and planning requirements.
- Need for Streamlined Licensing: Current licensing processes are often lengthy and cumbersome, necessitating reforms to facilitate project realization.
-
Energy Efficiency and Operational Challenges:
- Energy Loss: The process of pumping water uphill consumes more electricity than what is generated during the release, resulting in a net energy loss.
- Maintenance Requirements: Regular maintenance is needed to ensure efficient operation, adding to operational costs.
-
Market and Economic Factors:
- Cost Escalation: Projects face cost escalation during their multi-year development timeframes, impacting feasibility.
- Market Mechanisms: Current market mechanisms often fail to fully value the flexibility and grid stability benefits provided by PHS.
