Alternative Solutions Project
• Joint project by TSOs
• Communication with industry via DS3 Advisory Council and website
Phase 1 (5 months)
• Range of theoretical options assessed at a high level via weighted
scoring matrix approach
• Subset of viable options (2 to 3) selected for Phase 2 analysis
Phase 2 (13 months)
• More detailed review of the viable options from Phase 1
• Analysis focused on technical and financial aspects of each option

System Services
• DS3 System Services Procurement Design
– Competitive Multi Bid Auction and Regulated Tariff
• Decision paper by end of 2014
Demand Side Management
DSU
150 MW
• DSU Grid Code Working Group
– 4 modification approved by the Ireland GCRP
– Further consultation on frequency requirements and
performance monitoring
– SONI consultation on Grid Code modifications
• ESBN and NIE expressed concerns about
impact of DSUs on their system security
• Work on identifying and removing barriers to
service provision close to completion
