Deliverability of resource adequacy capacity on interties

The ISO methodology for determining the intertie capacity needed to accommodate resource adequacy supplies currently uses only historical data. This methodology ignores planned capacity upgrades, which can result in interties having a very low or zero capacity value. The ISO is initiating a stakeholder process to explore alternative methodologies for determining the resource adequacy intertie capacity and to consider ways of reducing import barriers for resources developing outside the California ISO.
