Title 16 › CHAPTER 46 — PUBLIC UTILITY REGULATORY POLICIES › SUBCHAPTER II — STANDARDS FOR ELECTRIC UTILITIES › § 2625
States or utilities must figure out how much it costs to serve each type of customer using methods the state regulators (for regulated utilities) or the utility itself (for nonregulated utilities) set. Those methods must, as much as possible, show cost differences from daily and seasonal use and from customer demand versus energy used. When making the methods, the regulator or utility must consider how total costs change if extra capacity is added for peak demand versus base demand, and how costs change if more kilowatt-hours are delivered. A utility’s time-of-day rates are “cost-effective” for a customer group if the long‑run benefits to the utility and those customers likely exceed the metering, communications, and other costs needed. A load-management technique is cost-effective if it likely cuts peak kilowatt demand and the long‑run savings to the utility are likely larger than the long‑run costs to install it. New multiunit buildings should have separate meters if each unit controls some electricity use and the long‑run benefits to residents exceed the cost of separate meters. An automatic adjustment clause (a rate rule that raises or lowers rates without a prior hearing to match utility cost changes) must be reviewed by hearing at least every 4 years to check it encourages efficient resource use, and reviewed at least every 2 years to ensure purchasing and operations are economical; reviewers may audit practices and require reports, including disclosures of ownership links with sellers. Each utility must send each customer a clear, short explanation of their current rate plan and any proposed change: within 60 days after service starts or within 90 days after the consumer‑information standard is adopted (whichever is later), and within 30 days after a rate change is filed (60 days if the utility bills every two months). Once a year the utility must send a short summary of major rate schedules and note any classes not summarized. On request, the utility must give a customer their actual (or degree‑day adjusted) monthly use for the past year if the data can be found. No service may be shut off without reasonable prior notice, a chance to dispute the reason, and notice of rights; and service must not be cut during times when shutting off would be especially dangerous to health if the customer shows they cannot pay now or can only pay in installments. Advertising terms: “advertising” = commercial messages to many people; “political advertising” = messages to influence public opinion on government or public issues; “promotional advertising” = messages to encourage use of the utility or related equipment. These do not include items such as energy‑saving tips, legally required notices, outage/safety/emergency notices, job ads, promotions for energy‑efficient products, or explanations of rates or hearing notices. Each state regulator must investigate and decide whether utilities should provide time‑based meters and communications so customers can take part in time‑based pricing and demand‑response programs.
