Take a NY Minute – Our KEDNY-KEDLI rate case agreements

Modernizing our gas system

This article is one of a series that will help create awareness on the major components of our KEDNY/KEDLI rate case agreements.

National Grid has served customers in the Brooklyn, Staten Island and Queens in New York City, and Long Island and the Rockaway Peninsula on Long Island for over 100 years and operates gas distribution systems that are among the oldest in the United States.  

Over the last several years, increased customer demand for natural gas, an industry-wide focus on gas safety, and severe weather events have highlighted the need to modernize our energy infrastructure. 

As a result of that focus, we strive for continuous improvement in safety performance by identifying, assessing and managing risks on the gas system – and making the necessary investments to modernize and reinforce our gas infrastructure.

“The $3 billion capital investment program outlined in our rate case agreements addresses this by focusing on maintaining safe and reliable delivery service, including improving system resiliency through extreme weather events, accelerating the removal of leak prone pipe and reinforcing our systems to maintain reliability and enable growth,” says Ross Turrini, Chief Gas Engineer, National Grid.

One of the cornerstones of this program is an aggressive schedule to accelerate the replacement of aging pipeline in our system.

Below are the targets for the KEDNY – KEDLI CY 2017-19 pipeline replacement program. Note the increase in acceleration when compared to the average targets during the previous 3-year period. We also have the ability to earn an incentive for each mile replaced above the incentive targets below. 

Our capital program also includes major investments to reinforcement our system to maintain reliability and enable growth.

  • Metropolitan Reliability Infrastructure (MRI) Project – will reinforce the backbone of the Brooklyn gas system with the installation of ~ 36,000 feet of 30-inch transmission main. This $252 million project will add 850,000 dekatherms of daily capacity and increase system reliability and operational flexibility.
  • Northwest Nassau Transmission Project – will improve safety and reliability, resolve low pressure issues and position the gas transmission system to accommodate a future supply point in Nassau County. This $284 million project involves the installation of over ten miles of 24-inch transmission main and the construction of two new regulator stations and reduce operating pressures in segments of existing gas mains.
  • Liquefied Natural Gas (LNG) Upgrade – our Greenpoint (NYC) and Holtsville (LI) LNG plants were put in service during the 1970s and are vital in ensuring our system is able to meet peak demand during the coldest days of winter. Major upgrades are planned to update the existing tanks at these plants.
