Commission reviews proposed demand charge for large electric customers; no vote taken
Summary
Staff outlined a proposal to add a demand charge for the city's largest commercial electric customers, explaining the charge would be revenue-neutral overall, target the top users and better align costs with those who drive system peaks; commissioners asked for further analysis and community outreach before any decision.
The Public Utilities Commission heard a detailed presentation on a staff proposal to introduce a demand charge for larger electricity customers and did not take a vote.
Shane Steel, a commission member who introduced the topic for the panel, said the demand rate would add a fee based on a customer's monthly peak demand in kilowatts on top of the existing monthly customer charge and per-kilowatt-hour usage charge. "The demand rate adds in a fee for their peak demand," he said, explaining that the meters capture the highest hourly demand in the billing month and that the fee is intended to allocate costs to customers who require larger capacity (transformers, lines) because of peak loads.
Staff walked commissioners through examples from the packet: the standard customer charge noted in the presentation was $52 per month with an energy charge of $0.11 per kWh; one illustrative demand-charge example showed a demand component of $8.40 per kilowatt. Staff emphasized the proposal is structured to be revenue-neutral across the customer class being considered so the utility would collect roughly the same total revenue while shifting the distribution of charges among large customers.
Key policy questions and next steps: Commissioners asked which customers would be included (staff suggested starting with the top ~20 by kilowatt sales or load), whether the city could or should phase the program in over two to three years, and how to communicate impacts to affected customers. Staff said they could show individual customer load curves offline but not share customer-specific data publicly. The presenters suggested an intention to refine inclusion thresholds, rate levels and a public outreach plan, and to report back to the commission late summer or early fall with recommendations.
Why it matters: Demand charges change how large customers are billed and can shift costs among commercial customers; staff said it is a common utility best practice to better align charges with the costs a customer imposes on system capacity. Commissioners emphasized the need for careful calibration and outreach if the PUC moves forward.
