(c) Special rules. If data for actual annual sales (for purposes other than resale)
are not available in the records of the public utility, the utility may use estimates
based on actual data available to it. If one purchaser maintains several billing
accounts with the public utility, the kilowatt hours purchased in each account of that
purchaser shall be aggregated to arrive at the total for that purchaser.
(d) Revision of the list. Each public utility relying upon any estimates for its
January 31st filing, shall revise the list compiled under paragraph (b) of this section
no later than March 1 of the year in which the list was originally filed to reflect actual
data not available to the utility prior to that time. Any revised list shall be filed with
the Commission and made publicly available through the utility's principal business
office no later than March 1. A utility filing a revised list shall indicate thereon the
changes made to the list previously filed under paragraph (b) of this section. On or
before the filing and publication of the revised list, the public utility shall notify the
newly-listed purchasers and any purchasers whose names were removed from the
list.
