The New York Power Authority provides transmission service in various parts of New York State over more than 1,400 circuit-miles of transmission facilities, which account for one-third of the state’s high-voltage lines. We operate and maintain our power lines with a strong commitment to safety and the environment and work closely with the New York Independent System Operator (NYISO), other transmission owners and the New York State Public Service Commission to help ensure a high level of power-system reliability.
On an annual basis, NYPA recovers the costs of its transmission system (the Annual Transmission Revenue Requirement or ATRR) through monthly billings made by the NYISO. The ATRR is calculated in accordance with the NYPA Formula Rate set forth in NYISO OATT Section 14.2.3.
By July 1st of each year, NYPA will calculate and publish the annual update of the ATRR and subsequently hold an open meeting and conference call to provide an opportunity for interested parties to obtain information about the annual update. The next open meeting date will be determined and posted on this webpage.

NYPA is engaged in a multiyear Life Extension and Modernization (LEM) of its transmission lines in Northern, Western and Central New York and of related facilities, such as switchyards and substations. Some of the transmission assets date back to the 1950s and 1960s when NYPA built its major hydroelectric plants on the St. Lawrence and Niagara rivers.
The $726-million transmission LEM program, begun in 2013 and extending to 2025, is one of the key elements of the New York Energy Highway Blueprint, a multifaceted initiative introduced by Gov. Andrew M. Cuomo to modernize the state’s electric power system. The NYPA transmission LEM includes capital investments in smart-grid technologies to enhance situational awareness of the conditions of power lines to help quickly address matters that could threaten equipment and power service reliability.
In March 2014, NYPA announced the completion of its modification to a transmission line in Northern New York, involving the separation of two high-voltage power lines that will contribute to integrating additional amounts of generation from North Country wind farms and improve power-grid reliability. The Moses-Willis Circuit Separation project fulfills a recommendation of the Energy Highway to help relieve transmission congestion and remove constraints on wind farms in Clinton and Franklin counties, in Northern New York.
Another Energy Highway initiative to be undertaken by NYPA includes the Marcy-South Series Compensation Project, which will help relieve transmission congestion from Central New York to the Catskills. The project will increase the amount of power that can be moved along existing transmission lines, without building new lines.
NYPA has been at the forefront of developments in transmission, including the installation at our Frederick R. Clark Energy Center in Marcy, near Utica, of a device known as the Convertible Static Compensator, the first in the world with the capability of instantaneously shifting power in the same substation from a heavily loaded transmission line to one with spare capacity.
NYPA line crews from St. Lawrence-FDR, Blenheim-Gilboa and the Clark Energy Center helped to repair storm-damaged high-voltage lines on Long Island following Superstorm Sandy, in 2012. They arrived with transmission line trucks and the necessary equipment to assist the Long Island Power Authority and National Grid in assessing the condition of their high-voltage transmission lines, and to provide support for the restoration to service of damaged lines across their service area.
NYPA’s transmission right-of-way maintenance program has received national recognition for its responsible environmental practices.
Customers can obtain service on the New York transmission system through the NYISO's OASIS (Open Access Same-Time Information System) node. All transmission service in the state is subject to the NYISO Open Access Transmission Tariff (OATT). Details of the tariff can be found on the NYISO web site.
The Power Authority belongs to the Northeast Power Coordinating Council, formed shortly after the 1965 Northeast Blackout to promote the reliability and efficiency of interconnected power systems throughout the northeastern United States and central and eastern Canada. Membership in this regional reliability council includes transmission providers, transmission customers, power pools and independent system operators in Northeastern North America.
