LIPA to upgrade transmission line

The line is about 10.6 miles long and uses about 170 structural poles. The width of the right-of-way is about 100 feet

New York City, July 19, 2012 — The New York State Public Service Commission has granted a certificate of environmental compatibility and public need to the Long Island Power Authority (LIPA) that will allow the utility to increase the design capacity of the existing 10.6 mile Wildwood to Riverhead electric transmission line from 69 kV to 138 kV.

The line is about 10.6 miles long and uses about 170 structural poles. The width of the right-of-way is about 100 feet. LIPA proposed to upgrade the transmission line from 69 kV by installing insulators capable of supporting 138 kV transmission using existing conductors and poles.

About 300 feet of underground 138 kV cable will be installed near the Wildwood Substation to transition the overhead line into the Wildwood Substation. LIPA states that no additional property rights will need to be acquired for the project.

Based on forecasted load growth, LIPA says the project will be needed prior to summer 2013. Demand on Long Island's East End has increased over the six-year period between 2000 and 2006 by an annual average of 5.2 percent. LIPA forecasts demand to increase on the South Fork at an annual average rate of about 3.3 percent through 2025. The project is a significant component of LIPA's plans to reinforce the existing transmission capacity of the South and North Forks of Long Island.
