Deliverability for distributed generation (completed)

Outcome: Effective Mar 05, 2014 the ISO implemented a new study in the transmission planning process to identify available transmission capacity that supports distributed energy resource deliverability status and does not require delivery network upgrades to the ISO grid or adversely affect the deliverability of existing or proposed new generation in the interconnection queue. — Implemented: Mar 05, 2014; FERC approval: Mar 05, 2014; Tariff amendment filing: Sep 18, 2012 (ER12-2643); Board of Governors approval: May 16, 2012

The ISO is proposing a new annual assessment methodology for determining and allocating resource adequacy deliverability for distributed generation resources. Currently, the ISO determines distributed generation deliverability through assessments in the ISO generator interconnection cluster study process. Load serving entities use the deliverability results for their procurement of distribution-connected generation to meet resource adequacy requirements. The new assessment would run parallel to the generation interconnection procedures and be coordinated with the interconnection procedures and the transmission planning process. This initiative is in support of the Governor of California’s goal of 12,000 megawatts of distributed generation by 2020.
