Power comes from PSEG Long Island
PSEG Long Island (Long Island Power Authority), a state utility, serves all of Southampton. Its homes paid an average of 26.2¢ per kWh in 2025, about $195 a month (its average across New York, for customers on its standard service). New York lets you buy power from another supplier; 0% of PSEG Long Island’s home customers do, and PSEG Long Island still delivers it.
Service territory: HIFLD Electric Retail Service Territories (map dated Aug 2023). Prices and customers: EIA-861, 2025.
Water comes from Suffolk County Water Authority
Suffolk County Water Authority supplies Southampton: about 70% of residents live in its service area. Hampton Bays Water District serves another 21%. About 5% of homes are outside any mapped community water system, most likely on private wells, which EPA doesn’t regulate. It draws ground water and serves 1,100,000 people in all.
No health-based violations reported to EPA in the five years to October 2026, like 82% of the 27 systems serving more than 1,000,000 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2025–Dec 2027, was 1.2 ppb, below the 15 ppb action level that applied. The highest in five years was 2.3 ppb. That’s lower than 60% of similar systems’ latest results.
