Commission hears technical briefing on demand charges, power factor and grid upgrades

City commissioners and staff received a technical explanation of how demand charges and power-factor penalties affect large commercial accounts and how grid upgrades could reduce losses.

A consultant who identified himself as John introduced his municipal practice and funding-capacity work and described the firm’s ability to scope projects from planning through construction. John said his team handles funding and technical planning for sewer, water and electrical infrastructure and that those services include analyzing meter data and long-term rate impacts.

Speakers explained that short 15-minute usage spikes — not total monthly consumption — often determine demand-charge assessments. Participants noted that improving the city’s power factor (target roughly 95–100) and reducing line losses are expected benefits of the proposed upgrade; the discussion included examples of current power-factor readings in the 40–70 range for some large commercial meters and the potential to reduce fines and monthly penalties once the upgraded system is in service.

Commissioners asked staff to provide the interval-meter data and clarified that residential and commercial rate schedules differ by season and meter-reading software; the commission asked for phased implementation options and clearer projections of near-term costs to users.
