Outages Sweep Upper Midwest and Northeast During Historic Heat
Severe thunderstorms on July 3-4 2026 knocked down power lines and trees from Iowa to New York and into southern Ontario. Authorities reported roughly 820,000 customers without electricity Saturday morning, with earlier estimates near one million on Friday. By noon the Northeast had about 750,000 outages, affecting Wisconsin, Michigan, Illinois, Pennsylvania, Ohio, New York and New Jersey.
Background, Grid Strain, and Key Numbers
Temperatures hit 98 °F in Central Park and 105 °F in Atlantic City, driving air-conditioning demand. The PJM Interconnection, serving 67 million people in the Mid-Atlantic, South and D.C., faced overloaded transmission lines and generator outages. PJM issued an emergency alert and asked demand-response participants to cut usage. Spot wholesale electricity prices in northern Virginia rose above $2,000 /MWh (later $2,500 /MWh) compared with $40 /MWh normally. PJM’s instantaneous load peaked at about 163 GW, near the 165.6 GW record.
Official Statements & Responses
Mayor Zohran Mamdani of New York City urged residents to use overnight cooling centers and dispatched crews to clear fallen trees. PJM’s emergency alert ordered demand-response customers to curtail usage and warned neighboring grids of export curtailments. D.C. Homeland Security and Emergency Management issued shelter instructions for the National Mall. Lake Geneva Mayor Todd Krause declared a local emergency after a storm-related boat capsizing.
Criticism & Opposition
Safety officials warned nighttime outages raise health risks for residents without cooling. Energy analysts said PJM’s strain from data-center and EV growth leaves capacity upgrades lagging demand. Community groups called for stronger emergency-power planning and additional cooling shelters.
On-the-Ground Reports
Thousands were evacuated from Washington’s National Mall as thunderstorms approached. New York City opened cooling centers in five boroughs. On Geneva Lake, a sudden storm capsized a motorboat, killing three children under 13; six adults and one child were rescued, children wore life jackets. Officials reported an injury from a falling tree and blocked streets due to downed power lines.
Conflicting Reports & Gaps
Sources differ on outage totals—NYT cites 820,000, CBS reports 750,000, and estimates neared one million. The number of heat-related medical calls is unclear; D.C. officials logged 45 patient contacts but did not specify how many were heat-induced.
