Developing new pumped hydro storage (PHS) projects faces several significant challenges:
Main Challenges
-
Regulatory Complexity and Delays:
- The regulatory process for new PHS projects can be lengthy and complex, involving various permitting requirements and environmental assessments.
- Delays in regulatory timelines can hinder project development and increase costs.
-
Environmental and Social Risks:
- PHS projects can have ecological impacts due to land acquisition, construction, and water usage, which may lead to community resistance.
- These risks require comprehensive environmental assessments and community engagement to secure social acceptance.
-
Financial Uncertainties:
- The financial viability of PHS projects often relies on market conditions and the ability to secure stable revenue streams.
- The lack of consistent market mechanisms to fully value PHS services, such as grid stability and long-duration energy storage, creates significant financial risks for developers.
-
Market Structures Undervaluing PSH:
- Current electricity market structures often fail to fully recognize the value of flexibility and non-energy services that PHS provides.
- This makes it difficult for developers to predict and secure revenue, hampering project feasibility.
-
Cost Escalation Over Time:
- PHS projects can take many years to complete, exposing them to cost escalation risks due to inflation and changes in materials and labor costs.
-
Technological and Operational Challenges:
- While PHS is a mature technology, integrating it with variable renewable energy sources requires advanced management systems to maximize efficiency and grid stability.
Addressing these challenges requires comprehensive upfront planning, regulatory support, and market reforms to ensure the financial viability and sustainability of PHS projects.
