NYISO updated the Operating Committee on Thursday that 89 MW of nameplate behind-the-meter solar was added onto the grid in June. The month’s peak load was 22,867 MW and the minimum was 11,999 MW.

Mark Younger, president of Hudson Energy Economics, referred to the growing megawatts of energy storage resources in New York and asked what percentage of them can sell capacity resource interconnection service. (See “May Operations Report,” NYISO Operating Committee Briefs: June 22, 2023.) CRIS rights are needed to take part in NYISO’s capacity market and can be obtained either through a transfer from a facility with existing rights or from ISO deliverability studies.

Aaron Markham, NYISO vice president of operations, responded, “I believe only half is available to sell capacity.”

Matt Cinadr, a power systems operations specialist with The E Cubed Co., asked whether NYISO has observed any issues with intermittent production and the amount of reserve fuel available.

Markham said, “we’ve definitely seen the levels of intermittent production increasing the volatility on the system, but at this point, it hasn’t been a driver of any reserve shortages.”

“As the amount of intermittents increases, however, I think we’re definitely going to see greater magnitudes of error and need to procure some market products to help manage that going forward,” he added.

DER Manuals

The OC also approved six revised manuals presented by NYISO that will support the implementation of distributed energy resources in New York’s markets.

These DER manuals include revisions to market procedures like ancillary services, control center requirements and emergency operations, and have been reviewed by all other applicable working or stakeholder groups. (See “DER Manual Updates,” NYISO Discovers Market Problem, Opens Confidential Investigation.)

NYISO still anticipates these approved manuals will become effective in parallel with other related DER tariff and market models.
