The retail rates to SOS customers will consist of the sum of the following components:
When the winning wholesale bidder(s) are selected for the Wholesale Full Requirements Service supply of SOS, the SOS Administrator shall submit to the Commission:
There shall be a period of seven (7) and twelve (12) calendar days for comments and reply comments after the SOS Administrator's submission to the Commission of the retail rates and administrative charge for the Wholesale Full Requirements Service supply of SOS, pursuant to Subsection 4103.2. The Commission shall thereafter issue an Order approving or rejecting the retail rates and/or administrative charge. The SOS Administrator shall file a revised tariff setting forth the new retail rates and/or administrative charges within seven (7) calendar days of the Commission's Order approving the rates and charges.
The administrative charge is designed to recover the SOS Administrator's incremental costs for procuring and providing the service. Actual incremental costs shall include, but not be limited to, a proportionate share of SOS customer uncollectibles for each SOS Customer Group, Commission Consultant expenses (as described in Subsection 4110.1), SOS bidding expenses for both the Wholesale Full Requirements Service supply of SOS and Long-Term Renewable Energy PPA or PPAs (including all incremental expenses associated with the development and execution of Long-Term Renewable Energy PPAs), working capital expenses related to SOS for each SOS Customer Group, wholesale supply transaction costs related to Wholesale SOS Provider administration and transmission service administration, wholesale payment and invoice processing, incremental billing process expenses, customer education costs, incremental system costs, costs related to the purchases of electric supply from CREFs, and legal and regulatory filing expenses related to SOS requirements.
Prior to the submission of bids for the Wholesale Full Requirements Service supply of SOS, the SOS Administrator shall file a request with the Commission (with notice to all the Parties) for determination of the appropriate amount of its administrative charge to be included in the retail rates to SOS customers. In calculating the Administrative Charge, the return component on the administrative charge, for the Wholesale Full Requirements Service supply of SOSas prescribed in Order No. 18829 issued July 7, 2017, and for the supply of SOS provided by the Long-Term Renewable Energy PPA or multiple PPAs as prescribed in Order No. 20327 issued April 9, 2020, as modified by any subsequent Commission Order or Orders, shall not be reflected for rate-making purposes in the establishment of the Electric Company's distribution rates, including the determination of the Electric Company's return for providing distribution service.
All customers eligible for SOS will be informed of the applicable SOS retail rates, to the extent practical, for the service at least two (2) months prior to the beginning of each service year. If it is not practicable to provide such notice, the SOS Administrator shall file with the Commission and serve upon the Parties notice of that fact, the reasons for the delay, and the expected date for the provision of such information.
Retail prices to customers shall be adjusted at least twice a year to reflect seasonal pricing and other appropriate price changes. Prior to each year of SOS, the SOS Administrator shall file with the Commission, estimates of actual incremental costs for the upcoming year. Such costs will be collected from customers, on a load weighted average, subject to an annual adjustment to reflect actual costs.
All investment, revenue and expenses associated with the provision of SOS by the Electric Company when serving as the SOS Administrator shall be separate from investment, revenues and expenses associated with the Electric Company's distribution service so that there will be no subsidization of the Electric Company's distribution rates.
All SOS Customer Groups, as defined in Subsection 4102.3 of these rules, are responsible for the costs associated with any and all Long-Term Renewable Energy PPAs.
