Coordination with utility distribution company

Before beginning the ISO New Resource Implementation process, a distributed energy resource provider must obtain concurrence from the applicable utility distribution company (UDC) or metered sub system (MSS) that there are no concerns about the distributed energy resources comprising a distributed energy resource aggregation. This concurrence review process takes 30 business days. We recommend that prospective distributed energy resource providers begin working with the applicable UDC/MSS prior to commencing the 30-day review process. Contact James Bishara at (916) 608-1226 or jbishara@caiso.com for information on the designated UDC/MSS contacts.
