AC Transmission Upgrades:
Reducing Congestion & Supporting Renewables
The Project’s Article VII application was submitted on August 20, 2019 and assigned case number 19-T-0549. Here’s a link to the filed documents list: NYDPS-DMM: Matter Master 19-01931/19-T-0549
In 2012, the New York State Public Service Commission (PSC) initiated a proceeding and invited developers to submit initial project ideas to achieve objectives defined within the New York Highway Energy Blueprint.
The PSC paused the process in 2014 to conduct a needs assessment of congestion in the Mohawk Valley and Hudson Valley in response to requests to reexamine the issues and need for transmission upgrades. After confirming the upgrades were required, the New York Independent System Operators (NYISO) issued a request in 2016 for proposals to address the underlying need.
In April 2019, NYISO selected a joint proposal by LS Power Grid New York (LS Power) (formerly known as North America Transmission, LLC) and the New York Power Authority (NYPA) to upgrade the transmission system within existing utility rights-of-way. NYISO’s selection is the final step in a series of processes lasting more than five years, with substantial public and stakeholder involvement, to identify the most efficient and cost effective transmission upgrades to reduce congestion, improve reliability, and provide better access to renewable resources around New York State by strengthening the transmission system.
LS Power will continue engaging local communities and other stakeholders, conducting environmental reviews, and advancing design engineering in support of the PSC’s Article VII permitting process. Construction activities will not begin until after approval of detailed construction plans is granted by the PSC, anticipated in mid-2020. The target in-service date for the facilities is in December 2023.
