1 DG Interconnection Procedures Collaborative January 20,

2 Interconnection Procedures Collaborative State Ombudsman kick-off October 2016 Goal: develop improvements to Con Edison s internal process for managing interconnections. In accordance with the New York State Public Service Commission Standard Interconnection Requirements (SIR) CE agrees to implement changes as appropriate following the discussions. Informational report filing 6 months from the initial meeting Topics discussed, recommendations developed, and actions taken. 2

3 Agenda Topics for today s meeting Future topics and Con Edison work plan Discussion: Three line diagram checklists Verification test checklist and FAQs Regular business meetings for projects SIR workflow 3

4 Future Topics and Timeline February 2017: Completion of topics from January meeting Coordination with DOB for discussion Standardizing communications to present consistent options Additional Topics for 2017 Con Edison Work plan Guides for DG technology March Company moving forward with PV and fuel cell guides as was presented New service vs DG cases coordination April Draft Informational Report on Collaborative Filing of Informational Report on Collaborative due April 24. 4

5 Draft Content for Three Line Diagram Checklists, Verification Checklists, FAQs Refer to documents 5

6 Process for regular business meetings Any DG >5MW normally have regular meetings DG Ombudsman Office and Energy Services available for meetings on request Pre-application discussions can help set realistic expectations on unusual schedule constraints Special billing considerations (RNM, CDG, Offset Tariff, etc) will meetings scheduled near commissioning for rates Developer feedback? How to find balance between transparent communications and efficient management of 111 cases under the new SIR >50kw. 6

7 SIR workflow discussion Refer to flow chart 7

9 Preliminary Screening Analysis If any of the following screens fail, applicant must request supplemental screen or CESIR to progress. Screens performed Screen A: Is the PCC on a Networked Secondary System? Screen B: Is Certified Equipment Used? Screen C: Is the Electric Power System (EPS) Rating Exceeded? Screen D: Line Configuration Compatible w/ Interconnection Type? Screen E: Simplified Penetration Test Screen F: Simplified Voltage Fluctuation Test Deliverable: Pass: Design Approval Letter and Executed Contract Fail: Preliminary Review Letter Template (w/ Options) 9

10 Supplemental Screening Analysis If any of the following screens fail, applicant must request CESIR to progress. Screen G: Supplemental Penetration Test Where 12 months of line section minimum load da ta is available, can be calculated, can be estimated from existing data, or determined from a power flow model, is the aggregate Generating Facility capacity on the Line Section less than 100% of the minimum load for all line sections bounded by automatic sectionalizing devices upstream of the Generating Facility? Screen H: Power Quality and Voltage Tests In aggregate with existing generation on the Line Section, a. Can it be determined within the Supplemental Review that the voltage regulation on the line section can be maintained in compliance with current voltage regulation requirements under all system conditions? b. Can it be determined within the Supplemental Review that the voltage fluctuation is within acceptable limits as defined by IEEE 1453 or utility practice similar to IEEE1453? c. Can it be determined within the Supplemental Review that the harmonic levels meet IEEE519 limits at the Point of Common Coupling (PCC)? Screen I: Safety and Reliability Tests Does the location of the proposed Generating Facility or the aggregate generation capacity on the Line Section create specific impacts to safety or reliability that cannot be adequately addressed without a detailed study? Deliverables: Pass: Design Approval Letter and Executed Contract Fail: Supplemental Review Letter Template (w/ Options) 10
