PSEG Long Island recently invested $4.8 million in two infrastructure upgrade projects in Huntington and Elwood.
A $3.1 million project at the Elwood substation installed new power control equipment that officials said will support voltage levels in the Town of Huntington. The addition will ensure voltages stay within the limits, which officials said will better support customer demands on the system.
That project is to be completed by June 1, officials said.
A separate $1.7 million project at the downtown Huntington substation installed a new transmission capacitor bank a grouping of equipment that can store electrical charge. Without the additional machinery, PSEG officials said the area could experience unacceptable low voltages that could lead to blackouts if a transmission system failure occurred.
PSEG also replaced aging and unreliable protective equipment, which officials said will give customers more reliability. That project was completed in October.
In both areas, PSEG officials said they were operating within voltage limits, but the improvements will ensure that the two substations continue to meet standards.
"The improvements we are implementing will help us deliver consistent, resilient power to our customers to keep them comfortable during the summer heat," John O'Connell, PSEG Long Island vice president of transmission and distribution, said in a statement.
