J-POWER cleared by the New York ISO to shut two Shoreham units in August 2017

The New York ISO on Nov. 16 issued a report that clears J-POWER USA Generation LP to retire Shoreham gas turbines (GT) 3 & 4 in August of next year.

On Aug. 13, J-POWER submitted a Generator Deactivation Notice for the proposed retirement of the Shoreham GT3&4. J-POWER reported that it intends to deactivate the two 51-MW generators on Aug. 13, 2017. The NYISO determined J-POWER’s Generator Deactivation Notice to be complete on Aug. 26, which is the Generator Deactivation Assessment Start Date.

The NYISO performed, in coordination with the Long Island Power Authority (LIPA), resource adequacy and transmission security analyses of the New York Control Area (NYCA) system to determine whether there was a reliability need for the units. If the NYISO were to find a need, then it would follow a process for soliciting and selecting a solution.

Said the Nov. 16 report: “As further detailed below, this analysis does not identify a Need for the 2017-2022 study period.”

The NYISO evaluated the period five years from the conclusion of the 365-day notice period (Aug. 26, 2017-Aug. 26, 2022) (the “Study Period”) using the most recent reliability planning process base case, with the load forecast consistent with the 2016 Load and Capacity Data Report (“Gold Book”).

Additionally, the NYISO performed a transmission security assessment for the Bulk Power Transmission Facilities (BPTFs) and LIPA performed a transmission security assessment of their non-BPTFs. The NYISO reviewed and verified the analysis performed by LIPA. No transmission security-related need was identified in the Study Period.

The study said that J-POWER may deactivate the generators on Aug. 26, 2017, or on an earlier date, after it completes all required NYISO administrative processes and procedures. The NYISO’s determination in this Generator Deactivation Process does not relieve J-POWER of any obligations it has with respect to its participation in the NYISO’s markets. If J-POWER rescinds its Generator Deactivation Notice or does not deactivate the generators by Aug. 26, 2018, then it will be required to submit a new Generator Deactivation Notice in order to deactivate the generators. This report concludes the Generator Deactivation Process.

The J-Power website says about this two-unit plant: “The Shoreham Facility is a 90.0 MW electric generating peaking facility, consisting of JET-A fuel-fired, simple cycle General Electric LM6000 PC SPRINT, located in Long Island, New York.”
