170 IAC 4-4.1-4 Filing of rate data

Sec. 4. (a) Each generating electric utility shall file with the commission each year all supporting data for the rates and rate filings required by this rule. (b) Each nongenerating electric utility shall file with the commission the revised rate schedule, tariff, or contract pursuant to which it purchases electricity from its supplier or each of its suppliers within sixty (60) days of the effective date of the revised rate schedule, tariff, or contract. At the same time, the nongenerating electric utility shall also file a report indicating its demand upon and the amount of energy received from each of its electricity suppliers during the most recent twelve (12) month period. If the electricity supplier's effective rate schedule, tariff, or contract contains multiple components in demand and energy rates, the demand and energy data submitted to the commission by the nongenerating electric utility for that electricity supplier should be set forth by rate component. When such rate components are based on system peaks, the date and hour of those peaks should also be supplied. (c) The commission may require the electric utility to provide additional data and justification for the rates and rate filings required by this rule.
