The Federal Energy Regulatory Commission on Jan. 23 accepted some proposed changes from the New York ISO in the power plant interconnection procedures related to plant uprates.
On Dec. 16, 2013, NYISO filed tariff revisions to its interconnection procedures set forth in Attachment X and Attachment Z to the NYISO Open Access Transmission Tariff (OATT) to modify the procedures pertaining to the evaluation of increases in the energy capability of existing generating facilities. NYISO proposed to use a de minimus criteria for determining when any increase in the capability of existing generating facilities is required to undergo the NYISO interconnection study procedures.
NYISO proposed that an increase in an existing large generating facility’s Energy Resource Interconnection Service (ERIS) capability that is associated with non-material equipment changes will not require a new interconnection study in any case where the increase is no more than 10 MW or 5% of a facility’s existing ERIS capability, whichever is greater. Similarly, an increase in a small generating facility’s ERIS capability associated with non-material equipment changes will not require a new interconnection study in circumstances where the increase is no more than 2 MW and which provides for a total ERIS capability of no more than 20 MW.
