1 PJM Interconnection 2750 Monroe Boulevard Norristown, PA Steven R. Pincus Associate General Counsel fax July 31, 2017 Honorable Kimberly D. Bose Secretary Federal Energy Regulatory Commission 888 First Street, N.E., Room 1A Washington, D.C Re: PJM Interconnection, L.L.C., Docket No. ER Solar Resources Meteorological Data and Forced Outage Reporting Revisions to PJM Tariff Pro Forma Service Agreements Dear Ms. Bose: Pursuant to Section 205 of the Federal Power Act ( FPA ) 1 and the Commission s Regulations, 2 PJM Interconnection, L.L.C. ( PJM ) submits for filing proposed revisions to pro forma service agreements in the PJM Open Access Transmission Tariff ( Tariff ) to require solar resource Interconnection Customers ( ICs ) to provide meteorological and forced outage data to PJM for purposes of power production forecasting. PJM proposes to revise the Form of Interconnection Service Agreement ( ISA ), Schedule H; and the Form of Interconnection Construction Services Agreement ( ICSA ), Schedule N, to incorporate requirements for solar resources to provide force outage data and sitespecific meteorological data including: temperature, atmospheric pressure and irradiance. PJM requests an effective date of September 29, 2017, for the attached revised Tariff sections U.S.C. 824d C.F.R. Part 35.

2 I. BACKGROUND On June 22, 2012, the Commission issued the Final Rule on the Integration of Variable Energy Resources. 3 Order No. 764 requires each public utility transmission provider to incorporate provisions into the pro forma Large Generator Interconnection Agreement (LGIA) requiring interconnection customers whose generating facilities are Variable Energy Resources ( VERs ) to provide meteorological and forced outage data to the public utility transmission provider for the purpose of power production forecasting. The Commission did not create an obligation to require VERs to provide meteorological and forced outage data in case where the transmission provider is not engaged in power production forecasting. 4 On November 12, 2013, PJM submitted proposed revisions to amend its pro forma ISA to add the meteorological data and forced outage requirements applicable to wind resources because, at that time, PJM s power production forecasting applied only the wind resources ( November 12 Compliance filing ). PJM acknowledged that if PJM should adopt additional forecasting tools in the future, PJM will develop and file with the Commission Tariff revisions to include in the pro forma service agreements data reporting requirements for solar resources. In the Order Accepting in Part and Rejecting in Part Proposed Tariff Revisions issued on April 17, 2014, 5 the Commission accepted in part and rejected in part PJM s proposed Tariff revisions submitted in the November 12 Compliance Filing. Regarding PJM s proposed meteorological and forced outage data reporting requirements, the Commission conditionally accepted PJM s proposed Tariff revisions. PJM s compliance 3 Integration of Variable Energy Resources, Order No. 764, 139 FERC 61,246 (2012), order on reh g, Order No. 764-A, 141 FERC (2012) (Order No. 764). 4 Order No. 764 P PJM Interconnection, L.L.C., 147 FERC 61,045 (2014) ( April 17 Order ). 2

3 filing submitted on May 19, 2017, addressing the Commission s directives in the April 17 Order was accepted by the Commission by letter order issued on June 30, PJM and its stakeholders recently adopted solar power production forecasting tools in addition to the existing wind power production forecasting tools. As a result, PJM now proposes to amend the PJM Tariff pro forma agreements consistent with the requirements of Order No In Order No. 764 the Commission stated when a transmission provider employs power production forecasting for solar resources, the IC must provide, at a minimum, site-specific meteorological data including: temperature, atmospheric pressure and irradiance; however, the exact specifications of data to be provided by the IC will remain subject to negotiation between the parties. 7 PJM s proposed Tariff revisions comport with these requirements. The proposed Tariff revisions include the stated minimum site-specific meteorological data and outage reporting requirements. In addition, the current pro forma service agreements language applicable to wind resources will also apply to solar resources as follows: The Transmission Provider and Interconnection Customer may mutually agree to any additional meteorological data that are required for the development and deployment of a power production forecast. All requirements for meteorological and forced outage data must be commensurate with the power production forecasting employed by the Transmission Provider. Such additional mutually agreed upon requirements for meteorological and forced outage data re set for below: II. PROPOSED TARIFF REVISION PJM proposes to revise the pro form ISA Schedule H as necessary to add solar resources to wind resources throughout Schedule H and provide the meteorological and forced outage data reporting requirements for solar resource. PJM also proposes parallel Tariff revisions to Attachment P, Form of Interconnection Construction Service 6 See Order No. 764 P Order No. 764 P

4 Agreement ( pro form ICSA ) Schedule N. 8 These changes are necessary to align the addition of solar resource power forecasting and generator outage reporting requirements in the ISA with all the pro form service agreements which address the interconnection requirements for wind and solar generation facilities. PJM also proposes two ministerial changes to pro form ISA, Schedule H (the version applicable for New Service Requests received before May 1, 2015). Two references to special protection system are changed to remedial action scheme. These changes are necessary to align the Tariff terminology with the terminology used by the North American Electric Reliability Corporation ( NERC ). In 2014, NERC retired from its glossary of terms special protection system or SPS and retained remedial action scheme or RAS as the industry-recognized term. III. STAKEHOLDER PROCESS PJM received unanimous stakeholder support for the proposed PJM Tariff revisions described herein. The proposed Tariff revisions were endorsed by PJM s Markets and Reliability Committee ( MRC ) on May 25, 2017, and PJM s Members Committee ( MC ) on June 22, 2017, with no objections or abstentions. IV. EFFECTIVE DATE PJM requests an effective date of September 29, 2017, for the attached PJM Tariff sections, which is more than 60 days after the filing date. V. DOCUMENTS ENCLOSED PJM encloses with this transmittal letter electronic copies of the clean and redline PJM Tariff sections. 8 The revisions proposed herein apply to the pro forma ISA version of Schedule H and the pro forma ICSA version Schedule N applicable to New Service Requests received before May 1, 2015, and the versions applicable for New Service Requests received on or after May 1,

7 {Include the following Schedule H, as applicable, for New Service Requests received before May 1, 2015} SCHEDULE H INTERCONNECTION REQUIREMENTS FOR A WIND GENERATION OR A SOLAR GENERATION FACILITY {Include the appropriate language from the alternatives below} {Include the following language if the Customer Facility is not a wind generation or a solar generation facility} Not Required [OR] {Include the following language when the Customer Facility is a wind generation or a solar generation facility} Schedule H sets forth requirements and provisions specific to the interconnection of a wind generation or a solar generation facility that is greater than 20 MW. All other requirements pertaining to the interconnection of generation facilities above 20 MW set forth in Appendix 2 of this ISA and Part IV of the Tariff continue to apply to wind generation or solar generation facility interconnections. A. Technical Standards Applicable to a Wind Generation or a Solar Generation Facility i. Low Voltage Ride-Through (LVRT) Capability A wind generation or a solar generation facility shall be able to remain online during voltage disturbances up to the time periods and associated voltage levels set forth in the standard below. The Schedule H LVRT standard provides for a transition period standard and a post-transition period standard. Transition Period LVRT Standard The transition period standard applies to wind generation or solar generation facilities subject to Commission Order No. 661 that have either: (i) Interconnection Service Agreements signed and filed with the Commission, filed with the Commission in unexecuted form, or filed with the Commission as non-conforming agreements between January 1, 2006 and December 31, 2006, with a scheduled in-service date no later than December 31, 2007, or (ii) wind generation Page 1

8 turbines subject to a wind turbine or solar generation procurement contract executed prior to December 31, 2005, for delivery through Wind generation or solar generation facilities are required to remain in-service during three-phase faults with normal clearing (which is a time period of approximately 4 9 cycles) and single line to ground faults with delayed clearing, and subsequent post-fault voltage recovery to prefault voltage unless clearing the fault effectively disconnects the generator from the system. The clearing time requirement for a three-phase fault will be specific to the wind generation or solar generation facility substation location, as determined by and documented by the transmission provider. The maximum clearing time the wind generation facility shall be required to withstand for a three-phase fault shall be 9 cycles at a voltage as low as 0.15 p.u., as measured at the high side of the wind generation or solar generation facility step-up transformer (i.e. the transformer that steps the voltage up to the transmission interconnection voltage or GSU ), after which, if the fault remains following the location-specific normal clearing time for three-phase faults, the wind generation or solar generation facility may disconnect from the transmission system. 2. This requirement does not apply to faults that would occur between the wind generator or solar generator terminals and the high side of the GSU or to faults that would result in a voltage lower than 0.15 per unit on the high side of the GSU serving the facility. 3. Wind generation or solar generation facilities may be tripped after the fault period if this action is intended as part of a special protection systemremedial action scheme. 4. Wind generation or solar generation facilities may meet the LVRT requirements of this standard by the performance of the generators or by installing additional equipment (e.g., Static VAr Compensator, etc.) within the wind generation or solar generation facility or by a combination of generator performance and additional equipment. 5. Existing individual generator units that are, or have been, interconnected to the network at the same location at the initial effective date of the Schedule H LVRT standard are exempt from meeting the Schedule H LVRT standard for the remaining life of the existing generation equipment. Existing individual generator units that are replaced are required to meet the Schedule H LVRT standard. Post-transition Period LVRT Standard All wind generation or solar generation facilities subject to Commission Order No. 661 and not covered by the transition period described above must meet the following requirements: 1. Wind generation or solar generation facilities are required to remain in-service during three-phase faults with normal clearing (which is a time period of approximately 4 9 cycles) and single line to ground faults with delayed clearing, and subsequent post-fault voltage recovery to prefault voltage unless clearing the fault effectively disconnects the generator from the system. The clearing time requirement for a three-phase fault will be specific to the wind generation or solar generation facility substation location, as determined by and documented by the Page 2

The maximum clearing time the wind generation or solar generation facility shall be required to withstand for a three-phase fault shall be 9 cycles after which, if the fault remains following the location-specific normal clearing time for three-phase faults, the wind generation or solar generation facility may disconnect from the transmission system. A wind generation or solar generation facility shall remain interconnected during such a fault on the transmission system for a voltage level as low as zero volts, as measured at the high voltage side of the wind or solar GSU. 2. This requirement does not apply to faults that would occur between the wind generator or solar generator terminals and the high side of the GSU. 3. Wind generation or solar generation facilities may be tripped after the fault period if this action is intended as part of a special protection systemremedial action scheme. 4. Wind generation or solar generation facilities may meet the LVRT requirements of this standard by the performance of the generators or by installing additional equipment (e.g., Static VAr Compensator) within the wind generation or solar generation facility or by a combination of generator performance and additional equipment. 5. Existing individual wind generator or solar generator units that are, or have been, interconnected to the network at the same location at the initial effective date of the Schedule H LVRT standard are exempt from meeting the Schedule H LVRT Standard for the remaining life of the existing wind generation or solar generation equipment. Existing individual generator units that are replaced are required to meet the Schedule H LVRT Standard. ii. Power Factor Design Criteria (Reactive Power) The power factor requirements for wind generation or solar generation facilities set forth in section 4.7 of Appendix 2 to Attachment O of the Tariff can be met by using, for example, power electronic devices designed to supply this level of reactive capability (taking into account any limitations due to voltage level, real power output, etc.) or fixed and switched capacitors, if agreed to by the Transmission Provider, or a combination of the two. The Interconnection Customer shall not disable power factor equipment while the wind generation or solar generation facility is in operation. Wind generation or solar generation facilities shall also be able to provide sufficient dynamic voltage support in lieu of the power system stabilizer and automatic voltage regulation at the generator excitation system if the System Impact Study shows this to be required for system safety or reliability. iii. Supervisory Control and Data Acquisition (SCADA) Capability The wind generation or solar generation facility shall provide SCADA capability to transmit data and receive instructions from the Transmission Provider to protect system reliability. The Transmission Provider and the wind generation or solar generation facility Interconnection Customer shall determine what SCADA information is essential for the proposed wind generation or solar generation facility, taking into account the size of the facility and its Page 3

26 {Include the following Schedule N, as applicable, for New Service Requests recived before May 1, 2015} SCHEDULE N INTERCONNECTION REQUIREMENTS FOR A WIND GENERATION OR A SOLAR GENERATION FACILITY {Include the appropriate language from the alternatives below} {Include the following language if the Customer Facility is not a wind generation or a solar generation facility} Not Required [OR] {Include the following language when the Customer Facility is a wind generation facility} Schedule N sets forth requirements and provisions specific to the interconnection of a wind generation or a solar generation facility that is greater than 20 MW. All other requirements pertaining to the interconnection of generation facilities above 20 MW set forth in Part IV of the Tariff continue to apply to wind generation or solar generation facility interconnections. A. Technical Standards Applicable to a Wind Generation or a Solar Generation Facility i. Low Voltage Ride-Through (LVRT) Capability A wind generation or a solar generation facility shall be able to remain online during voltage disturbances up to the time periods and associated voltage levels set forth in the standard below. The Schedule N LVRT standard provides for a transition period standard and a post-transition period standard. Transition Period LVRT Standard The transition period standard applies to wind generation or solar generation facilities subject to Commission Order No. 661 that have either: (i) Interconnection Service Agreements signed and filed with the Commission, filed with the Commission in unexecuted form, or filed with the Commission as non-conforming agreements between January 1, 2006 and December 31, 2006, with a scheduled in-service date no later than December 31, 2007, or (ii) wind generation turbines or solar generation subject to a wind turbine or solar generation procurement contract executed prior to December 31, 2005, for delivery through Page 7

27 1. Wind generation or solar generation facilities are required to remain in-service during three-phase faults with normal clearing (which is a time period of approximately 4 9 cycles) and single line to ground faults with delayed clearing, and subsequent post-fault voltage recovery to prefault voltage unless clearing the fault effectively disconnects the generator from the system. The clearing time requirement for a three-phase fault will be specific to the wind generation or solar generation facility substation location, as determined by and documented by the transmission provider. The maximum clearing time the wind generation or solar generation facility shall be required to withstand for a three-phase fault shall be 9 cycles at a voltage as low as 0.15 p.u., as measured at the high side of the wind generation or solar generation facility stepup transformer (i.e. the transformer that steps the voltage up to the transmission interconnection voltage or GSU ), after which, if the fault remains following the location-specific normal clearing time for three-phase faults, the wind generation or solar generation facility may disconnect from the transmission system. 2. This requirement does not apply to faults that would occur between the wind generator or solar generator terminals and the high side of the GSU or to faults that would result in a voltage lower than 0.15 per unit on the high side of the GSU serving the facility. 3. Wind generation or solar generation facilities may be tripped after the fault period if this action is intended as part of a special protection system. 4. Wind generation or solar generation facilities may meet the LVRT requirements of this standard by the performance of the generators or by installing additional equipment (e.g., Static VAr Compensator, etc.) within the wind generation or solar generation facility or by a combination of generator performance and additional equipment. 5. Existing individual generator units that are, or have been, interconnected to the network at the same location at the initial effective date of the Schedule N LVRT standard are exempt from meeting the Schedule N LVRT standard for the remaining life of the existing generation equipment. Existing individual generator units that are replaced are required to meet the Schedule N LVRT standard. Post-transition Period LVRT Standard All wind generation or solar generation facilities subject to Commission Order No. 661 and not covered by the transition period described above must meet the following requirements: 1. Wind generation or solar generation facilities are required to remain in-service during three-phase faults with normal clearing (which is a time period of approximately 4 9 cycles) and single line to ground faults with delayed clearing, and subsequent post-fault voltage recovery to prefault voltage unless clearing the fault effectively disconnects the generator from the system. The clearing time requirement for a three-phase fault will be specific to the wind generation or solar generation facility substation location, as determined by and documented by the transmission provider. The maximum clearing time the wind generation or solar generation facility shall be required to withstand for a three-phase fault shall be 9 cycles after which, if the fault remains following the location-specific normal clearing time for three-phase faults, the Page 8
