The supply, generation, or energy supplier line changed even though household kWh stayed similar.
A third-party supplier or retail electric plan can change the supply price separately from delivery charges. A teaser rate, variable rate, contract renewal, or cancellation fee may affect the bill.
Check first
Find supplier name, supply rate, contract dates, and variable-rate language.
Compare supply cents per kWh with the previous bill and utility default option.
Check whether the plan renewed, expired, or changed mid-cycle.
Separate supply changes from delivery, taxes, and fixed charges.
Practical savings moves
Use all-in rate math before changing appliances or habits.
Review cancellation rules and renewal dates before switching plans.
Track kWh separately from supply price so usage savings stay visible.
Keep a copy of the supplier terms used for the bill.
Avoid these mistakes
Do not judge a supplier plan from advertised supply rate alone.
Do not ignore delivery charges that remain with any supplier.
Do not miss cancellation or renewal terms when chasing a lower rate.
