Prince Edward Island’s electricity regulator has approved a four-year phase-out of Maritime Electric’s residential high-use discount and directed the utility to equalize rural and urban residential service charges, while leaving the treatment of large farms for further review.
The Island Regulatory and Appeals Commission’s April 29, 2026 ruling, Order UE26-02, Docket UE22503, did not itself change electricity bills. The residential energy-rate reform was approved in principle for implementation through the utility’s next general rate application, with updated revenue requirements and cost information.
The separate direction to use one residential monthly service charge was to be implemented with commission approval through that application or by April 1, 2027, whichever came first. The order did not fix the dollar amount of the common charge.
Who pays for the electricity system?
Rate design determines how an approved revenue requirement is divided among customer groups. Maritime Electric’s proposal sought to reduce cross-subsidies: its evidence showed general-service customers paying more than their allocated cost of service while residential customers, including farms, paid less.
The company filed its application in May 2021. The process included public questions, independent expert analysis and participation by the P.E.I. Federation of Agriculture and the P.E.I. Energy Corporation. A public hearing took place on October 1, 2025.
The commission assessed fairness, costs caused by each customer group, non-discrimination and revenue sufficiency. Its target was generally to bring each class’s revenue within 95 to 105 per cent of its allocated costs. A revenue-neutral redesign can still increase one group’s bills while reducing another’s; it does not mean every customer pays the same amount.
Volume discount to be phased out
Under the declining-block structure examined in the case, residential customers paid a lower price per kilowatt-hour for consumption above 2,000 kilowatt-hours in a billing period. The commission found this inconsistent with cost responsibility and modern rate design, because high-use customers benefited from lower marginal prices while lower-use customers could shoulder a disproportionate share of fixed costs.
It accepted that gradually eliminating the second block would improve fairness and reduce the shock of changing bills. Maritime Electric must provide proposed schedules and bill-impact analyses for the four-year transition in its next general rate application.
The commission also approved proposed adjustments to the large-industrial, street-lighting and general-service classes for implementation with that application. The changes were designed to rebalance cost responsibility rather than increase the utility’s overall revenue through rate design alone.
Farm rates require more evidence
Maritime Electric proposed allowing large farms to move to the small-industrial class if advantageous. The Federation of Agriculture instead supported a separate farm class and retaining a lower second-block rate for those customers. The utility opposed creating another class, while the commission’s expert questioned whether rates designed for small industry reflected farm demand patterns.
The parties also disagreed over whether costs should be allocated using the single highest system peak or an average of three monthly peaks. That choice could materially affect which customers subsidize others.
The commission found insufficient quantitative evidence of the system-wide effects. It required a comparison of both approaches and a draft farm class, including eligibility rules and supporting costs. The order kept large farms in the residential class pending that review rather than approving a new farm tariff.
One residential service charge
The commission rejected maintaining different monthly service charges solely because a residential customer lived in a rural or urban location. The evidence described changes in meter-reading technology and customer density that reduced the historical cost distinction.
Maritime Electric agreed a single charge was preferable but wanted to defer the change because of revenue-rebalancing and technology-investment concerns. The commission nevertheless directed uniform charges, subject to the implementation timetable and approval process.
The ruling separates agreement on the direction of reform from approval of the actual schedules customers will pay. It leaves the farm-class issue for a further evidentiary review and does not authorize every element of the company’s longer-term, second-stage plan.
