Finance
• Support Systems are driving development in Ireland and most of the EU– Feed in Tariff in Ireland provides a floor of €75/MWhr– ROC System in UK provides top up revenue of £50/MWhr
• Market Integration is a policy priority• Market Structures under pressure with new power
systems– More capital intensive cost base– Low marginal generation costs
• More risk sensitive finance providers

Stabilise Policy
• Difficult credit environment
• Clarity is essential
• Regulatory systems and market design should
promote market certainty
• Scope to improve BES scheme

Expiring Permissions
• Long lead time for Grid Connections
• Planning Consents typically expire after 5 years
• NI system requires Grid applicants to have a planning permission

Overview
• Ireland and New Zealand
• International Factors
• Ireland’s Energy System
• Achieving High Renewable Penetration
• Observations for the Future
![Page 30: Wind Energy in Ireland](https://reader036.fdocuments.us/reader036/viewer/2022062410/56815e60550346895dccda0f/html5/thumbnails/30.jpg)
Observations
1. A long term energy strategy is a necessary first step2. Markets need to value the full energy product
– Energy– Secure supply– Price stability– Strategic Energy Security– Carbon Costs and Benefits
3. System Operation with large wind is achievable
![Page 31: Wind Energy in Ireland](https://reader036.fdocuments.us/reader036/viewer/2022062410/56815e60550346895dccda0f/html5/thumbnails/31.jpg)
Observations
4. Consistent application of a strategy between agencies is a make or break factor
5. Other industries are impacted web farms, supply chain etc.
6. Copenhagen is not the end of the process on international agreement
7. Community and society involvement essential
