Missouri’s Hot Weather Law will be in effect from June 1 through Sept. 30.
The law was created to protect residential customers of investor-owned utilities from having their electric or natural gas service disconnected due to non-payment when electricity or natural gas is used as the source of cooling or to operate the only cooling equipment at the residence.
A change to Missouri law enacted through Senate Bill 4, passed in 2025, expanded the forecast protection period under the Hot Weather Law from 24 hours to 72 hours.
