Industry Value Chain
Generation Distribution Suppliers/
Customers
Evolution of Value Chain:
1. Competition in generation and supply
2. Introduction of Independent Regulatory Authority
3. Network Businesses remain as „natural monopolies‟, but regulated
4. Independence of Transmission System Operators
5. Evolution of Wholesale Power Markets
6. Strategic push towards regional markets (EU)
Transmission

TSO Renewable Facilitation Studies
Objectives:
• Increase our understanding of the behaviour of the power system with large amounts of renewable generation
• Identify any potential technical issues
• Develop mitigation measures
• Wrap it all up in a comprehensive strategy for the operation of the power system with large amounts of renewables
Studies:
• 4000 Frequency response studies 5000 Transient Stability studies
• 1000 Short Circuit Level studies Analysis of Wind patterns
First comprehensive study of its kind in the World

Case for further interconnection
• This confirms the very strong economic case for the
East-West Interconnector.
• Further interconnection between AI and GB is
economically attractive.
• Interconnection from Ireland to France also appears
beneficial, but further detailed work is required to verify
this and evaluate this against Ireland – Great Britain
interconnectors.
• Interconnection assists in integration of more wind on
the system, particularly for export.

EirGrid Off-Shore Grid Study
Study Objectives:
•Develop optimised off-shore grid
development strategies
•Utilise that strategy to inform the TSO
offshore functional designs and policies
Scenarios:
•3/5/7GW off-shore.
•Study Period out to 2030
•Part A: off-shore Ireland only
•Part B: incorporating links to rest of
Europe
Will feed into other broader-based
studies (ENTSO-E, SEI etc.)

Context
• Moneypoint, peat and oil plants set to close: fuel diversity issue.
• Debate should now progress to longer term policy
• Goal will be a transition to a low carbon electricity system.
• Wide range of options have development potential in this timeframe.

Summary
• Significant emissions reductions can be achieved in all portfolios
• All portfolios have higher capital costs and lower running costs relative to today.
• Under current policies the gas portfolio is the most likely outcome and could be viewed as a transitional step towards carbon neutrality by 2050.
• Coal CCS, nuclear, high renewables, storage and interconnection are all able to further reduce emission levels, however a number of technical, environmental and cost issues would need to be overcome

Conclusion
• The purpose of this report is to contribute to a debate on energy policy.
• It builds on, and is complementary to, the Joint Committee’s previous consultation and report on Electricity Needs post 2020.
• There are no simple or easy choices in this complex area.
