PSEG Bringing More Backup Generators East

May 29, 2018 6:52 PM

Even though backup generators that PSEG Long Island staged at local substations last summer were only used briefly on two occasions, the utility has increased the amount of backup power it has on hand for this summer.

The Long Island Power Authority earlier this month signed off on PSEG putting four additional portable backup generators at the East Hampton Village substation, in addition to the 12 generators that were parked on the site last year. The 16 generators, which run on natural gas, are capable of producing about 17 megawatts of power, compared to 12 last summer.

Six generators are also being staged in Montauk, the same number as last year, capable of producing 6 megawatts of power.

Officials from PSEG said that last summer’s relatively cool weather on weekends helped avoid the need for supplementing the power supply at times of peak load, which is typically late in the afternoon and evening on hot summer weekends. But peak demand growth forecasts continue to grow on the South Fork, and the additional generators match what PSEG had planned for 2018 after last summer.

The Montauk generators were the only backups that were fired up last summer, on two occasions: once when an equipment failure at the Montauk substation caused a drop in supply, and the second time as a precaution when demand was climbing.
