HVDC (High voltage direct current) power systems use D.C. to transmit bulk power over long distances. For long-distance power transmission, HVDC lines are less expensive, and losses are less as compared to AC transmission. It interconnects networks with different frequencies and characteristics, typically when the direct-current voltage exceeds 100 kV.

Persistent Congestion on NYISO’s Central East Interface: The End is in Sight | Congestion Watch Blog

The Central East Interface is one of New York’s most congested corridors, enabling Upstate generation to serve the robust load levels Downstate. Congestion on the interface and the Zone F/Zone E basis spread has increased significantly in the past 1.5 years as a result of construction on the Central East Energy Connect, one of the two projects under the AC Transmission Upgrades PPTN. In addition to construction-associated outages, higher delivered gas prices in eastern New York have contributed to increased congestion.

Transmission Watch™ Report Published for Q1 2021

In today’s Transmission WatchTM report, ESAI Power analysts assess the NYDPS report on the power grid mandated by the Accelerated Renewable Energy Growth and Benefit Act. Our analysis looks at the need for coordination between renewables and energy storage deployment. This will have implications on the competitive market structure in the NYISO.

Need Coordination Between Renewables and Energy Storage Deployment in NYISO | Transmission Watch Blog

In our latest Transmission Watch report, we identify the need for coordination between renewables and energy storage development in NYISO.  ESAI’s analysts take an in-depth perspective on the New York Department of Public Services (NYDPS) initial report on the Power Grid to the New York Public Service Commission (NYPSC) in January. This Power Grid Study was mandated by the April 2020 Accelerated Renewable Energy Growth and Community Benefit Act. This study seeks to identify transmission investments that are necessary to achieve climate goals under New York’s July 2019 Climate Leadership and Community Protection Act (CPCLA).
