Powering the Future: How to Unlock the Grid for Clean Energy Growth with Rob Gramlich

Green Giants: Titans of Renewable Energy Podcast

In this episode of Green Giants, host Wes Ashworth welcomes Rob Gramlich, founder and president of Grid Strategies LLC. With decades of experience in renewable energy and grid policy, Rob dives deep into the challenges and opportunities shaping the future of the U.S. power grid.

Key Discussion Points:

1. The Grid’s Role in Renewable Energy Expansion:
   • Rob highlights how the grid is both a facilitator and a bottleneck for clean energy. As the energy landscape shifts towards higher renewable penetration, the need for smarter grid planning becomes more urgent.
2. Barriers to Grid Modernization: The Three P’s – Planning, Permitting, and Paying:
   • Planning: Coordinating transmission lines across multiple regions is complex and often lacks foresight.
   • Permitting: Linear infrastructure faces stiff resistance, both from local communities and bureaucratic hurdles.
   • Paying: With costs distributed across states, disagreements arise about who should bear the financial burden.
3. Grid Constraints and Interconnection Challenges:
   • Rob discusses the 2.6 terawatts of renewable energy waiting in interconnection queues, double the U.S.’s current capacity. He explains how outdated infrastructure limits clean energy integration and increases curtailments.
4. Grid Enhancing Technologies (GETs):
   • Technologies like dynamic line ratings, topology optimization, and power flow control could unlock significant grid capacity by improving efficiency and reducing curtailments.
5. Utilities and Innovation Challenges:
   • The utility business model, which rewards large capital investments, sometimes discourages low-cost solutions like GETs. Rob underscores the need for regulatory incentives to push utilities toward adopting advanced technologies.
6. Legislative Updates and Policy Shifts:
   • With FERC initiatives like Order 1920 and potential permitting reforms in Congress, Rob remains hopeful for progress in grid expansion and modernization. He stresses the importance of bipartisan cooperation to achieve long-term energy goals.
7. Decentralized Energy Systems:
   • While microgrids provide resilience, Rob is skeptical about their potential for large-scale clean energy solutions, emphasizing the importance of macro-grid planning to handle high renewable penetration.
8. Outlook on Future Innovations:
   • High-voltage DC lines, advanced conductors, and clean firm power options like enhanced geothermal or long-duration storage are poised to shape the next phase of grid evolution.

Closing Thoughts:

Rob shares his optimism that national security concerns and economic development will drive bipartisan support for grid infrastructure. He encourages industry stakeholders to adopt innovative solutions and work collaboratively across sectors to overcome challenges.
