1.  Public hearing.  A consumer-owned transmission and distribution utility that elects to set rates under this section may not increase or decrease any rate, toll or charge without first holding a public hearing at which the Public Advocate and any customer of the consumer-owned transmission and distribution utility may present testimony and may question the officials present regarding the proposed rate change.  

2.  Notification.  The consumer-owned transmission and distribution utility shall, at least 30 days prior to the hearing, publish a notice of the amount of the proposed rate change, the percent of change for each customer class and the hearing, including the date, time, place and purpose of the hearing, in a newspaper of general circulation in the area encompassed by the consumer-owned transmission and distribution utility. In addition, 60 days prior to the hearing, the consumer-owned transmission and distribution utility shall notify the commission and the Public Advocate of its intent to change rates, tolls or charges.  

3.  Ratepayer notification.  Each consumer-owned transmission and distribution utility shall give, at least 30 days prior to the public hearing, one notice to each of its ratepayers of:  

4.  Customer rights.  At the commencement of each hearing held pursuant to this section, the consumer-owned transmission and distribution utility shall inform those present of customer rights as specified in subsection 3, that the rate change may be investigated by the commission in accordance with subsection 8 and that petitions filed pursuant to subsection 8 must bear the signature, printed name and address of the signer. Upon request, the utility shall provide customers with petition forms that include a place for signatures and the printed names and addresses of the signers.  

5.  Supporting materials.  The consumer-owned transmission and distribution utility shall file a copy of all materials supporting the proposed rate change with the commission and the Public Advocate, at least 30 days prior to the hearing. A copy of all material supporting the proposed rate change must be made available to customers for examination at the offices of the consumer-owned transmission and distribution utility for at least 30 days prior to the hearing. The consumer-owned transmission and distribution utility shall promptly provide any relevant additional material or information requested by a customer or by the commission or by the Public Advocate.  

6.  Filing changed rates.  The consumer-owned transmission and distribution utility shall file its changed rates with the commission within 30 days of the public hearing, but not sooner than 10 days following the public hearing. The commission may order the consumer-owned transmission and distribution utility to correct any mathematical or clerical errors.  

7.  Effective date of rate change.  Subject to the notice and waiver requirements of section 307, consumer-owned transmission and distribution utilities electing to set rates under this section may establish an effective date for any rate change of at least one month, but not more than 9 months, from the date the rates are filed with the commission.  

8.  Authority to investigate rate changes.  If, within 30 days of the public hearing, 10% of the customers of the consumer-owned transmission and distribution utility or 750 customers, whichever is less, file with the utility and with the commission petitions requesting a review of the rate change by the commission, the rate change may be suspended, investigated, reviewed and changed by the commission in accordance with section 310, except that no suspension ordered issued by the commission pursuant to section 310 may be effective for a period greater than 9 months from the date the rate changes were filed.  

9.  Procedures for suspension of rate change.  If the number of signatures on the petition is at least 750 or if the number of signatures on the petition equals or exceeds 10% of the customers indicated on the consumer-owned transmission and distribution utility's most recent annual report on file with the commission, the commission may suspend the rate change pursuant to section 310. The commission shall notify the utility of the suspension.  

10.  Transmission and distribution utility may challenge petitions.  A consumer-owned transmission and distribution utility has 10 days from the receipt of notice to notify the commission and the lead petitioner whether it intends to contest any aspect of the validity of the petitions, after which it loses that right. If the utility intends to challenge the validity of individual signatures on the petitions, it shall identify, in its notice to the commission and lead petitioner, the specific signatures it is challenging and state the grounds for challenging each signature it believes is invalid. When the utility files its notice of intent to challenge the validity of the petitions, the utility shall provide the commission and the lead petitioner with a list of its customers. If the utility notifies the commission in a timely fashion that it wishes to contest the validity of the petitions, the commission shall set the matter for hearing. It shall hold the hearing and issue its decision on the validity of the petitions within 30 days of notification by the utility that it intends to contest the validity of the petitions. If the commission finds the petitions to be invalid, it shall lift its order of suspension. For the purposes of this section, "customer" means, in the case of residential accounts, any one adult residing in a household where the utility's transmission and distribution service is provided and, in the case of all other accounts where the utility's transmission and distribution service is provided, a corporate officer, a partner or a proprietor. No more than one person may sign on behalf of an account. A person may not sign on behalf of more than one account unless the person is a customer at each account.  

11.  Review of rates under section 310.  Nothing in this section prohibits a consumer-owned transmission and distribution utility from petitioning the commission for review pursuant to section 310 in the first instance.  

12.  Frequency of rate increases.  A consumer-owned transmission and distribution utility may not institute a general increase in its rates under this section within one year of its most recent general increase in rates pursuant to this section. For the purposes of this section, a "general increase in rates" means any change in the rates, tolls and charges of a consumer-owned transmission and distribution utility, the effect of which is to increase the annual operating revenues of a consumer-owned transmission and distribution utility by more than 1%.  

13.  Penalty.  If, upon the filing of a rate change pursuant to this section, the commission finds that the utility has failed to comply with this section, the commission may suspend the rates for investigation pursuant to section 310. If there is a substantial procedural violation of this section, the commission may prohibit the utility from filing rates pursuant to this section in its next rate case.
