As Summer’s Start Brings Extreme Heat, PSEG Long Island Reminds Customers to Prepare and be Safe

(UNIONDALE, N.Y. – June 20, 2025) Just in time for the beginning of summer, extreme heat is in the forecast for the next several days. PSEG Long Island has sufficient electric capacity to meet projected peak demand and is here for customers and the community.

According to the National Weather Service, hot and humid conditions will produce maximum heat index values above 90 degrees beginning Sunday and continuing through the middle of next week. Parts of the region are expected to see heat index levels around 100 degrees on Monday and Tuesday. The heat index is a measure of how hot it really feels when relative humidity is factored in with the actual air temperature.

“PSEG Long Island prepares all year round to provide customers with safe, reliable electric service. To handle summer’s extreme weather, we have been upgrading equipment, carefully planning to provide sufficient electric capacity to meet peak demand, and positioning our personnel to respond effectively if needed. We would also like to remind customers of the importance of personal safety in times of high heat.”

-  Michael Sullivan, Vice president of Electric Operations, PSEG Long Island

During extreme heat conditions, customers should:

• Seek out air-conditioned spaces, if possible, if their homes become too warm.
• Stay hydrated by drinking plenty of water. Avoid drinks with caffeine or alcohol.
• Avoid wearing dark colors because they absorb the sun’s rays.
• Never leave children or pets alone in enclosed vehicles.
• Avoid strenuous exercise during the hottest part of the day, which is between 10 AM and 2 PM.

High temperatures can also lead to higher energy use, resulting in higher electric bills. To help save energy and money this summer, PSEG Long Island recommends the following tips for customers:

• Do not cool an empty house. Set your thermostat higher when you are away or use a smart thermostat to control the temperature in your home. Customers can receive an incentive on qualifying thermostats for enrolling in PSEG Long Island’s Smart Savers Thermostat program, which can be used to control usage during peak summer days. Visit psegliny.com/efficiency for more details.
• Customers on Time-of-Day rates who have a programmable or smart thermostat can automate the following steps.
  • At noon (three hours before peak hours), set the thermostat temperature 3 degrees lower than your usual setting so your home is cool and comfortable as peak period begins. Peak hours are from 3 -7 PM weekdays.
  • At 3 PM, when peak hours begin, set the thermostat temperature 3 degrees higher than your usual setting so that the air conditioner runs less often, while not letting your home get too warm.
  • At 7 PM, when peak hours end, set the thermostat to return to your usual setting. 
• Seal holes and cracks around doors and windows with caulk or weather-stripping.
• Replace air filters monthly. Dirty filters make your air conditioner work harder.
• Operate appliances in the morning or evening when it is cooler outside. 
• Set refrigerators and freezers to the most efficient temperatures.
• Replace old appliances with new, energy efficient ENERGY STAR® appliances. 
• Close blinds and draperies on sun-facing windows to keep out the sun’s heat.
• Ceiling fans cool fast and cost less than air conditioning. (In hot weather, set your ceiling fan to spin quickly, counterclockwise to push air downward toward the floor.)
• Run the dishwasher, clothes dryer and other high-energy-use appliances in early morning or at night.
• Charge electric vehicles overnight.
