3 Determining the Applicable Interconnection Process for ERIS One of three interconnection processes apply to proposed interconnection in New York The applicable interconnection process depends on: the proposed size and location of the interconnecting project and the market in which it intends to participate (wholesale or retail). The applicability of these different processes are summarized on the following slides 3

4 Determining the Applicable Interconnection Process for ERIS NYISO s interconnection procedures govern the interconnection of resources when: the developer intends to make wholesale sales and the developer proposes to interconnect to (i) transmission or (ii) distribution facilities on which there is already a generator making wholesale sales (i.e., FERCjurisdictional distribution ) New York State Standardized Interconnection Requirements (SIR) govern the interconnection of resources when: the developer is interconnecting to portions of the distribution system other than FERC-jurisdictional distribution and the resource is less than or equal to 5 MW Utility interconnection procedures govern the interconnection of resources not subject to the NYISO or SIR processes 4

5 Determining the Applicable Interconnection Process for ERIS A developer may request a determination from the NYISO regarding whether its proposed interconnection is subject to the NYISO s SGIP This may be requested under Section of Attachment Z to the OATT This may also be requested as part of a pre-application request (a $1000 request for information regarding a proposed interconnection prior to submitting an Interconnection Request) See Section of Attachment Z to the OATT 5

8 NYISO s SGIP NYISO SGIP (OATT Attachment Z) is the NYISO s interconnection process for the following Small Generating Facilities 20 MW or less: New facilities 20 MW or less that meet both of the following criteria: Facility proposes to interconnect to FERC-jurisdictional facilities (i.e., transmission facilities or distribution facilities on which there is already a generator making wholesale sales); and Facility intends to make wholesale sales (via injection) Existing facilities 20 MW or less that make material modifications or material increases to their facilities If an increase to the facility results in the facility exceeding 20 MW, the modification/increase is subject to the Large Facility Interconnection Procedure Qualifying Facilities that seek the right to participate in the wholesale market will be studied in the NYISO s interconnection process under certain circumstances (depending upon the proposed point of interconnection, whether the facility is new, whether, if existing, the facility increasing its output, etc.) 8

9 NYISO s Interconnection Queue Administration Projects assigned Queue position based on date Interconnection Request (IR) received Demonstration of Site Control is required with a Small Generator IR NYISO Queue is not a Hard Queue in which IRs are evaluated in sequential order Projects can advance on different schedules Small generators may be studied in clusters if interconnecting in close proximity (See Att. Z, Section ) Status of Queue Projects is updated monthly on NYISO public website As of August 31, 2018, there are 74 Small Generators in the Interconnection Queue for total of 1304 MW 9

10 Alternative Paths under the SGIP Fast Track Process $500 application fee For eligible projects, provides an expedited process Eligibility based upon the generator type, size, voltage of the line and the location of and type of line at the Point of Interconnection (see following slide) Normal Study Process with up to 3 studies, all of which can be waived First study Feasibility Study is optional, at the option of the Developer System Impact Study and Facilities Study may be waived upon mutual agreement of NYISO, Developer and Connecting TO Even under the normal study process (i.e., if a project is not eligible for Fast Track or fails the Fast Track screens), the SGIP is flexible enough to allow all 3 studies to be waived, allowing a project to go directly to an Interconnection Agreement 10

11 SGIP Fast Track Process Eligibility 11

12 SGIP Fast Track Process Validation of Fast Track Request (10 Business Days) If submission is invalid or lacks information, customer has 10 Business Days to provide the missing information/cure the deficiency NYISO notifies customer that its Interconnection Request is valid/complete and whether it is eligible for Fast Track Process If eligible for the Fast Track process, the NYISO and CTO must make Reasonable Efforts to complete the Fast Track screens in Section within 15 Business Days If project passes the Fast Track Screens, it proceeds directly to an Interconnection Agreement. If project fails the Fast Track screens, the NYISO and CTO determines if the facility may nevertheless interconnect reliably If yes, project proceeds directly to an Interconnection Agreement. If no, project may proceed to a Customer Options meeting 12

13 SGIP Fast Track Process Customer Options Meeting Purpose is to review possible facility modifications or the screen analysis and related results, and to determine what further steps are needed to permit the facility to be connected safely and reliably One of the following must occur at the Customer Options meeting: CTO offers to perform facility modifications or Minor Modifications to its system and provide a non-binding good faith estimate (if the customer agrees to pay such costs), the project proceeds directly to an Interconnection Agreement; or NYISO offers to perform a supplemental review under Section and provide a non-binding good faith estimate of the costs of such review; or Customer may proceed to the normal study process under the SGIP 13

14 SGIP Fast Track Process If project moves forward to the Supplemental Review process, such review must be completed within 30 Business Days of receiving study cost deposit Customer is responsible for actual costs of the review NYISO to provide estimate of study costs upfront Requires deposit for the estimated study costs within 15 days of the offer to perform such review Supplemental Review will consist of three additional screens (Minimum load screen, Power quality and voltage screen, & Reliability and safety screen) NYISO, in consultation with the CTO, must perform the screens within 30 Business Days of receiving the study cost deposit. 14

15 SGIP Normal Study Process Optional Feasibility Study (FES) Customer may opt to waive the FES unless it proposes multiple POIs FES is a high level study that evaluates proposed Point of Interconnection (and alternative POIs as requested) and the proposed configuration The focus of the FES is on the local system FES study report includes preliminary nonbinding cost estimate for SUFs System Impact Study (SIS) May be waived upon mutual agreement of customer, NYISO and CTO Intermediate level study that evaluates project impact on system reliability Includes updated nonbinding cost estimate for SUFs Not subject to review by stakeholders and does not require Operating Committee approval Facilities Study (FS) May be waived upon mutual agreement of customer, NYISO and CTO Facilities Study determines binding cost estimates and cost allocation for Local SUFs Not subject to a Class Year study unless non-local SUFs are identified (or the project is larger than 2 MW and requesting CRIS) 15

16 Process for Evaluation of CRIS Requests Resources larger than 2 MW requesting CRIS CRIS request must be evaluated in a Class Year Study Required for any resource larger than 2 MW that requests CRIS even if the resource is not subject to the NYISO s interconnection procedures Class Year deliverability study evaluates a group of CRIS requests together and determines deliverability and if not deliverable, the respective cost allocation for System Deliverability Upgrades 16

17 The Mission of the New York Independent System Operator, in collaboration with its stakeholders, is to serve the public interest and provide benefits to consumers by: Maintaining and enhancing regional reliability Operating open, fair and competitive wholesale electricity markets Planning the power system for the future Providing factual information to policy makers, stakeholders and investors in the power system 17
