Public Service Enterprise Group’s (PSEG) PSEG Long Island on Jan. 7 said that it energized on Dec. 7, 2020, the new 7.3-mile, underground Western Nassau Transmission Project, which is designed to increase the reliability and resiliency of the electric system in western Nassau County, N.Y.
“Western Nassau County had two major transmission lines connecting the substations in the area, which were sufficient when initially installed. However, populations have grown, electronic devices are essential to modern life, and energy grid redundancy standards have been adjusted accordingly,” Peggy Keane, vice president of Construction and Operations Services for PSEG Long Island, said in the statement.
Keane added, in part, “The completion of the Western Nassau Transmission Project adds a third transmission line that provides additional delivery capacity to ensure customers in the area have safe, reliable power and offers additional protection if there is an electrical system impact.”
The company noted that it began construction in December 2019, installing conduits, manholes, and cable beneath surface streets before repaving the roads and restoring curbs along the project route.
As noted in the Long Island Power Authority’s (LIPA) 2021 proposed budget, the project has a total cost of about $106.3m, with project to date expenditures through Dec. 31, 2020, being $100.3m.
Other major projects — with a total cost greater than $25m — listed in the budget include the “Syosset to Shore Road” project, which involves installing new 138-kV transmission circuit at a total project cost of $239.4m; the “Utility 2.0 Smart Meters” project, which involves replacing existing meters with smart meters at a total project cost of $194.1m; and the “Southampton” project, which involves installing new 138-kV cable to Deerfield at a total project cost of $115.8m.
Separately on Jan. 7, PSEG’s Public Service Electric & Gas (PSE&G) said that it has received approval from the New Jersey Board of Public Utilities to invest about $700m during the next four years to provide its 2.3 million electric customers with smart meters, which, as the company noted, are the foundation of PSE&G’s Energy Cloud — Advanced Metering Infrastructure effort that will create an integrated, two-way communications network between electric customers and the utility.
