Removing Barriers To Efficient Transmission Investment
Problem:– Renewable Generation is Different – Current Interconnection Policies Create Barrier
ISO Proposal
– Financing Mechanism Allows Appropriate Sizing
– Risk of Stranded Costs Systematically Mitigated

Intermittent Resource Integration
Challenge
– Mismatch between output and load curve
– On-peak capacity highly variable depending on the day
Increasing ISO attention to integration issues – Challenge can be overcome – Improving technology– Mitigation strategies– Better forecasts and operating systems
ISO Role to Facilitate State Policy Objectives
ISO Success Tied to State Success
