The City of Miami joins Coffeyville as Grand River Dam Authority customers who have to raise electric utility rates.
The rate increase is due to a rise in the costs of producing electric power passed down by GRDA, who implemented an 11% increase for 2025 and will add another four point one percent increase in 2026. Miami Special Utility Authority electric utility rates have not been increased since 2021. MSUA customers will see an increase of 12% starting this month and a five percent increase starting in July 2026 and 2027.
The three-year rate plan means an MSUA residential customer using 1,000 kWh would see an increase this month of $9.96 and pay $136.75 for 1,000 kWh, and another increase of $10.06 in total on July 2026 and pay $146.81 per 1,000 kWh. The average MSUA residential customer uses 865 kWh and for that usage, the bill would go from the current amount of $111.46 to $120.37 in 2025, to $129.62 in 2026, and $136.10 in 2027.
The City of Coffeyville recently approved an increase of two percent starting next month, then five percent in January of 2026 and finally a seven percent increase in 2027 and 2028. A graph comparing utility rates in the area can be seen below. With the upcoming increase, Coffeyville ranks as the lowest price per 1,000 kWh.
