Clearing Price Volatility
The NYISO Installed Capacity Market clearing price determines the compensation for Power Generation Owners. The Winter 2023/24 price forecast reveals significant changes compared to Winter 2022/23, with volatility in clearing prices predicted across all zones.
- Zone J (NYC): Changes in the UCAP requirement and potential retirements resulting from NYC’s DEC peaker NOx rule may impact clearing prices.
- NYCA: The New York Control Area (NYCA) will be impacted by potential retirements and a fluctuation in the level of imports expected from PJM.
- G-J Locality and Zone K: These zones are also impacted by changes in both retirements and fluctuations in imports from PJM.
Contributing Factors to Volatility
The main factors contributing to the volatility in clearing prices are:
- Expected retirements of power generation units
- New Renewable Capacity additions
- Uncertainties in Imports
The NYISO Installed Capacity Market for Winter 2023/24 promises to be dynamic and shaped by various factors, including retirements, updated reliability requirements, and import changes. As New York prepares for another winter, stakeholders in the energy market must closely monitor these developments to help inform their Capacity auction bid strategies throughout the winter period.
