The New York Independent System Operator (NYISO) released its Comprehensive Reliability Plan (CRP), which concludes that the New York State bulk supply system will meet system requirements and reliability criteria from 2021 to 2030 under normal weather conditions.

However, the report points out that the margin for maintaining reliability over the next 10 years will narrow or could be eliminated depending on changes in expected system conditions. It also highlights some of the reliability risks, such as delayed implementation of planned generation and transmission projects, additional generator shutdowns beyond planned or unplanned outages, and the impacts of extreme weather conditions.

“The latest study shows that our reliability margins are declining to worrying levels starting in 2023,” said Zach Smith, vice president of systems and resources planning. “We need to be careful with the grid in transition in order to maintain reliability and avoid the kinds of issues we’ve seen in other parts of the United States.”

The report adds that the potential reliability risks identified in the analyzes can be addressed through the commissioning of new capacity resources, the construction of additional transmission facilities and / or increased energy efficiency, the integration of energy resources. distributed and growth in demand response participation.

Further, the report states that while battery storage resources help fill the voids in renewable resource production, extended periods quickly deplete storage capacity. This will translate into the need for longer-term distributable emission-free resources. Although significant amounts of distributable and emission-free resources are required to balance the renewable intermittency on the system, they are not commercially available at present. However, they will be essential for the future reliability of the network. The report suggests that the necessary distributable emission-free resources could exceed 32,000 MW, about 6,000 MW more than the total of fossil-fueled power plants on the New York grid in 2021.

While New York State’s bulk supply system will meet all currently applicable reliability criteria from 2021 to 2030 for expected system demand during normal weather, the CRP has made several risk-based recommendations for the reliability of the bulk feed system.

Specifically, NYISO will continue to monitor the completion of identified projects and the progress of local transportation projects with respect to reliability needs initially identified in the reliability needs assessment. It will also administer its short-term reliability process to deal with generator deactivation notices and other system changes on a quarterly basis. In addition, NYISO will continue to address identified reliability issues for the ten year planning horizon. In addition, the report demonstrates that system margins are expected to shrink to a level that warrants a review of current reliability rules, procedures and practices. Finally, NYISO will continue to monitor and participate in other planning activities, including PSC procedures taking into account CLCPA requirements and the implementation of the Renewable Energy Accelerated Growth Act and community benefits.
