If we missed you at the informational forums and public statement hearings on March 3-5, our information boards are available here.  If you’d like to provide a statement to be incorporated into the project’s Article VII permitting record, please follow the instructions provided in the Other Ways to Comment section here.  Comments should refer to “Case 19-T-0549 – LS Power Grid NY”.  Although comments submitted will be accepted throughout the pendency of the proceeding, they are requested by April 3, 2020.

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 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 fall 2020.

New York Energy Highway Blueprint

New York State is fortunate to have significant power generation capabilities. However, the state’s transmission lines don’t have the capacity to convey enough energy from where it is produced to where it is most needed.

These bottlenecks cause inconsistent service and present barriers to potential development projects – stunting local economic growth. Transmission bottlenecks on the electric grid currently cost ratepayers hundreds of millions of dollars annually in higher electricity bills.

New York State’s public policy objective is to reduce these bottlenecks through transmission upgrades that increase the amount of power that can flow across the state, and improve the overall efficiency of the electric grid.

Investments in the transmission system can:

  • Lower electricity costs for ratepayers

  • Help retain jobs in upstate power plants

  • Encourage renewable energy projects

  • Create construction jobs

  • Improve grid reliability by replacing aging infrastructure
