Interconnection Specialists ensure all projects are treated in accordance with the current applicable tariff provisions

After the study process, main contact becomes your ISO contract negotiator Reports will be issued using Resource Interconnection Management System database (RIMS). It is imperative that project owners apply for access at the earliest opportunity following submission of an Interconnection Request. Interconnection Specialists ensure all projects are treated in accordance with the current applicable tariff provisions

Interconnection Specialists also ensure all projects are treated in accordance with the current applicable tariff provisions

Examples may include administration, operations, planning, and accounting requirements and the market that are consistent with the ISO tariff.

Cluster is the most common study type; a group of Interconnection Requests studied together to determine system impacts Delineation within the interconnection process due to size

See Appendix DD Section 1.3 There is no study or analysis performed as part of the pre-application process. Pre-Application Request Form is similar to a scaled version of an Interconnection Request (IR)

Deliverability is the difference between a project that is Energy Only and Full Capacity. Resource Adequacy requirements: the incentive is that the resource can receive NQC payments in addition to what it receives for supplying energy.

Tariff Appendix DD Section 9.2 Payment of study fee does not guarantee of deliverability Previously studied for EO: Option A not allocated TP Deliverability that converted to EO Option B which chose Partial Capacity deliverability, now wants additional deliverability Both Option A and B must have GIAs in good standing. * Cluster or ISP projects (plus PTO WDAT projects) that didn t originally request FC or PC deliverability on the original IR, or * FT projects that would now like to try and obtain deliverability, or *projects that didn t receive all of the deliverability you wanted or needed through the TPD allocation process (which I will cover in a moment) *For projects that lost deliverability by not maintaining the requirements.

Tariff Section 40.4.6.3 This process is not part of GIDAP (Tariff Appendix DD); the process is outlined in California ISO Tariff Section 40.4.6.3 UDC manages the application process and assignment of deliverability subject to the California ISO Tariff. California ISO reviews the applications and validates assignments. Only applies to distribution level projects ONLY. Qualifying Facilities (QF) conversions have grandfathered deliverability. DG must complete New Resource Implementation Checklist to utilize the assigned deliverability

Allocation criteria (captured in affidavit) (Tariff Appendix DD 8.9.2): All deliverability projects must meet minimum permitting and financing criteria to be eligible for an allocation of deliverability. Minimum requirement for permitting is IC has applied for the necessary governmental permit or authorization for the construction. Minimum requirement for financing involves balance sheet financing, commitment of project financing for full MW amount, regulator approved PPA meeting specific criteria, or included on an active short list... Only Option A projects may park the first time through.
