AC Transmission Upgrades: Reducing Congestion & Supporting Renewables
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 suspended 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 LS Power Grid New York, LLC (formerly known as North America Transmission, LLC) as the developer of the AC Transmission Upgrades. The New York Power Authority (NYPA) is a minority project partner and will be responsible for aspects such as operations and maintenance. 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 and conducting environmental reviews to develop a permitting-level project plan that will feed into the New York Public Service Commission’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 required in-service date for the facilities is in December 2023.
