Quick question on filing deadlines. I have a potential rate optimization claim for a client in Nevada served by NV Energy. We discovered they should have been on Schedule TOU-GS instead of GS-2 for the past two years. Savings would be about $3,200 per year. What's the typical statute of limitations for rate refund claims? Nevada PSC website isn't clear on this.
Filing Deadlines for Rate Refund Claims
Nevada generally allows 2-3 years for billing error claims, but rate schedule disputes can be trickier. Since the utility has discretion on rate assignments, they might argue the customer was properly classified at the time. I'd file the claim quickly and include documentation showing the customer met TOU-GS requirements during the entire period. The worst they can do is deny it.
Margaret's advice is good. I'd add that you should document when the customer first qualified for the lower rate schedule. If there was a change in operations or usage pattern that made them eligible, the refund period might start from that date rather than the full 2 years. NV Energy is usually reasonable on legitimate rate optimization claims in my experience.
