Background
The EverPower Wind Holdings Cassadaga wind project is a 126 MW wind farm in Arkwright, Charlotte, and Cherry Creek in Chautauqua County, New York. The project was subject to the New York State Article 10 Siting Process. EPE assisted EverPower in providing all the information required in the 1001.8 Exhibit 8 of Article 10 as part of the Article 10 Application.
Challenge
EPE evaluated the effects of the proposed 126 MW Cassadaga wind generation facility, planned to interconnect at the National Grid 115 kV Moon switching station, on the energy dispatch of must-run resources within the New York ISO (NYISO) service territory for 2019. The must-run resources for this purpose are defined as existing wind, hydroelectric and nuclear facilities, as well as co-generation facilities to the extent that the latter are obligated to output their available energy because of their steam hosts.
Approach
EPE modeled and ran the NYISO 2019 system, with and without the proposed Cassadaga wind project and compared the generation dispatch of must-run resources in the NYISO service territory between the two cases in order to analyze the impact of the Cassadaga project on must-run units in NYISO.
EPE also evaluated the impact of the Cassadaga project on the emission levels. This analysis was performed using GE’s Multi-Area Production Simulation software which is heavily utilized for market studies within the NYISO service territory.
Outcome
While the EPE study identified that the Cassadaga wind project insignificantly impacted the dispatch of the must-run generation, it identified that the project, if built, would result in drastic reduction of CO2 emissions. EPE’s analysis assisted EverPower in filing the Article 10 Application for the Cassadaga wind project with the New York State Board on Electric Generation Siting and the Environment.
