Utility Rate Stabilization Act Sets October Rollout for Mitcham Households
Mitcham residents will see the first adjustments to their combined utility statements under the new state legislation beginning with October billing cycles.
How we reported this
The Utility Rate Stabilization Act passed the state legislature last month and directs the public utilities commission to apply new rate calculation formulas to residential accounts. The changes affect water, electricity and natural gas charges for all households served by the regional provider that covers Mitcham. Implementation begins with the October 2026 billing statements mailed to customers.
Why the changes arrive this year
State fiscal office reports show the legislation responds to volatility in wholesale energy contracts signed in 2024. The act requires the commission to recalculate the fixed customer charge and the variable usage tiers every six months using a formula tied to the prior quarter's average procurement cost. Policy analysts note the first recalculation uses data from April through June 2026, which will appear on statements residents receive in early October.
Local advocates note that Mitcham households have faced three successive increases in the fixed charge since 2023. Under the new statute the fixed charge is capped at its June 2026 level for 18 months while the usage tiers are adjusted downward for the first 500 kilowatt-hours and the first 10,000 gallons of water.
When residents will notice differences
The legislation states that the new tiered rates apply automatically to usage recorded after 1 September 2026. A household that used 450 kilowatt-hours in September will see the lower first-tier rate on its October statement. The state fiscal office projects an average monthly reduction of $11.40 for a typical Mitcham single-family home under the initial calculation, based on 2025 consumption patterns reported by the regional utility.
Business accounts and multi-unit buildings follow a separate schedule that begins in January 2027. The act requires the commission to publish the exact tier boundaries for each six-month period on its website at least 30 days before they take effect. Residents who receive paper statements will find a one-page insert explaining the new structure in their October envelope.
The commission must complete its first formal review of the formula by March 2027 and submit findings to the legislature. Any further adjustments after that date will be announced at least 60 days in advance, according to the statute.
