Lecture Notes: Challenges and Opportunities in the UK's Renewable Energy Sector

Introduction

• The lecture discusses challenges facing the UK's renewable energy sector, focusing on grid connections and contracts for difference (CFD) auctions.
• Key speakers: Ed Porter and Ed Burkett from Low Carbon.

Overview of the Current System

• CFD auctions occur annually, taking six months from start to finish.
• There is potential for a continuous auction process to balance volume and consumer prices.

Cost and Investment

• Massive infrastructure investments needed, potentially trillions globally.
• Breakdown of costs:
  • Grid connection application fees: tens of thousands
  • Securing land: hundreds of thousands
  • Planning application: millions
  • Building a project: hundreds of millions

Government and Policy Challenges

• The policy on strategic spatial energy planning is underdeveloped.
• Connection queue status: 700 gigawatts as of June, with a need for only 200.
• Need for rules requiring developers to progress or leave the queue.

Low Carbon's Role and Achievements

• Low Carbon has consented to 1.6 gigawatts of solar projects in the UK.
• Recently received planning consent for a 500 MW solar farm in Lincolnshire.

Challenges with Grid Connections

• Projects face long lead times due to equipment and grid connection delays.
• Importance of CFD auctions for renewable project viability.

Proposed Solutions and Reforms

• Suggested running CFD auctions twice a year.
• Continuous CFD auctions could help maintain low prices for consumers.
• Grid queue rules need reform to prioritize viable projects.

Implications for Solar and Storage

• Potential for co-location of storage with solar projects.
• Storage can mitigate curtailment but faces barriers in current grid rules.

Future Market Considerations

• Important markets for renewable energy projects include the UK and Ireland.
• Ireland's approach to grid connections could offer lessons.

Connection Queue and Reforms

• Grid connection queue issues are prevalent across many markets.
• New proposals aim to introduce milestones for projects to progress.
• Emphasis on securing land rights as a key milestone for project development.

ESO and Energy Market Design

• The ESO (Electricity System Operator) is proposing reforms to prioritize certain projects.
• Concerns about market uncertainty and investment delays due to lack of clear prioritization rules.

Strategic Spatial Energy Planning

• There's a need for more strategic planning in the energy sector.
• Government's Clean Power Mission needs to inform policy and planning.

Conclusion

• Emphasis on using existing network infrastructure more efficiently.
• Encouragement for strategic spatial energy planning to support government goals.

Additional Insights

• Market design insights from US deregulated energy markets can provide valuable lessons.
• Strategic energy planning must balance market-driven approaches with necessary government intervention.
