Tim from Denver. Just completed my first demand charge dispute. Client had a 15-minute demand spike caused by simultaneous start of three large pumps after an emergency shutdown. The spike registered at 680 kW when their normal peak is around 290 kW. Dispute was based on the anomalous non-recurring nature of the event. Sharing the experience for others who have not done this yet.
My first demand dispute — how I prepared and what happened
Dave from Charlotte. Great to hear about first-hand experience. What did you submit and how long did it take?
Tim again. I submitted a two-page letter with three attachments: the interval data showing the spike in context of 12 months of normal demand, the client's incident report from the day of the emergency shutdown, and a simple chart showing how far outside the normal range the spike was. The letter explained the cause and argued the spike was non-recurring and non-representative.
Dave again. How did the utility respond?
Tim here. Initial response was a form letter saying the meter read correctly. I escalated by requesting a formal review citing the tariff's provisions for unusual operating conditions. Second response was from the commercial accounts supervisor. They accepted the dispute and rebilled the month using the 90th percentile demand from the prior 12 months.
Karen from Boise. The escalation path is key. Most frontline reps do not have authority to adjust demand readings. The commercial accounts supervisor level is usually where these disputes actually get reviewed on their merits.
Karen, one thing I would add — do not be discouraged by the form letter first response. It is almost automatic. The real conversation begins with the second escalation.
Nancy from St. Louis. Tim, what was the dollar value of the recovery?
Tim last time. About $3,200 for that single month plus the ratchet tail extending through several subsequent months. Total recovery around $9,400 over six months.
