The New York Independent Service Operator (ISO) issued the following warning on Friday, July 3, “An Energy Watch for July 2 has been issued due to a decline in operating reserves. The grid is operating normally at this time and there are adequate resources to meet forecasted demand. Visit nyiso.com/system-conditi to learn more.”
New York City Mayor Zohran Mamdani shared the warning, adding, “New York ISO just issued an early warning that we must alleviate the strain on our energy grid statewide. Please do your part in keeping our power on by: •Setting your AC to 78 degrees. •Turning off lights and unplugging electronics you’re not using. •Waiting until early morning or late at night to run appliances like dishwashers or laundry machines. During a historic heatwave, AC will save lives — but only if we keep the grid stable enough for it to stay on.”
As reported, Con Ed issued a warning July 2 to residents of the Northwest Bronx and Upper Manhattan to conserve energy amid ongoing repairs in the area. The latest warning from the ISO appears to be for the entire city. For an extensive list of tips on how to Beat the Heat, click here and / or refer to the below fliers.

Spray caps are available at local fire houses and can be affixed to fire hydrants to cool off, while simultaneously conserving water needed for fire fighting. Per NYC Department of Environmental Protection (DEP), opening fire hydrants without a spray cap can cause a sharp drop in water pressure, reducing water for firefighters and leaving your water supply with low pressure, outages, or brown water.
Upper floors are often affected first, DEP officials said. “Only open a hydrant with a spray cap, free for anyone 18 or older at local firehouses. A capped hydrant uses far less water and keeps pressure up for everyone. Report uncapped open hydrants to 311,” they added.
