Distribution rates and
riders
11
Rider RC (Retail Capacity)
 Based on PJM market capacity price for the delivery period.
 Converted into retail rates.
 Rider RC will be adjusted before each of the three delivery periods in the ESP.
 Rider RC is fully avoidable by shoppers.
12
Rider RE (Retail Energy)
 At the wholesale level, calculated by subtracting the capacity price for the delivery period from
the blended auction price.
 Converted into retail rates by adjusting for losses, taxes, and seasonality / blocks (for some
rates).
 Rider RE will be adjusted before each of the three delivery periods in the ESP.
 Rider RE is fully avoidable by shoppers.
13
Rider ESSC (Electric Security Stabilization Charge)
 Collects $110 million per year for three years.
 Expires after 12/31/14.
 Will be trued up each year.
 Rider ESSC is non-bypassable.
14
Rider SCR (Supplier Cost Reconciliation)
 Reconciles the Rider RE and Rider RC revenues received from retail customers with the
payments owed to auction providers.
 Recovers costs associated with auctions (e.g., consultants, setting up CBP website, etc.)
 Adjusted quarterly.
 Normally bypassable for shopping customers, but Rider SCR contains a non-bypassable
provision.
15
Rider SCR (Supplier Cost Reconciliation) – “Circuit Breaker”
 Subject to Commission approval, Rider SCR becomes applicable to all retail jurisdictional
customers in the Company’s electric service territory including those customers taking
generation service from a CRES provider under the following circumstance:
 The revenue balance within the SCR account becomes equal to or greater than ten percent of the
Company’s total actual SSO revenues collected for the most recent twelve month period under Riders
RE, RC, RECON, RTO, and AER-R. The total actual SSO revenue will be determined from data
covering the most recent quarter for which it is available.
 Duke Energy Ohio shall apply to the Commission for confirmation that the Company should modify
the Rider such that it becomes non-bypassable regardless as to whether or not the balance in the
Rider results from over- or under-recovery.
 For customers of CRES providers, Rider SCR will become bypassable again when, at the
time of the quarterly filing, the Rider balance of over- or under-recovery falls below the ten
percent threshold.
16
Rider AERR (Alternative Energy Recovery Rider)
 Recovers the cost of Renewable Energy Certificates (RECs) associated with SSO (i.e., nonswitched) load.
 Adjusted quarterly.
 Rider AERR is fully avoidable by shoppers.
17
Rider UE-GEN (Uncollectible Expense - Generation)
 Recovers uncollectible accounts expense related to generation service, including Percentage
of Income Payment (PIPP) customer installments not collected through the Universal Service
Fund Rider.
 Non-bypassable, except it is bypassable for accounts that are not designated for Duke Energy
Ohio’s Purchase of Accounts Receivables program.
 Adjusted annually.
18
Rider LFA (Load Factor Adjustment Rider)
 Revenue neutral to Duke Energy Ohio.
 Adjusted quarterly.
 Rider LFA is non-bypassable.
 Rider LFA applies to customers taking service under Rates DS, DP, and TS.
 Demand charge and kWh credit.

20
Alternative Energy, Energy Efficiency, Peak Demand Reduction
 ESP does not impact commitment to meeting alternative energy, energy efficiency, or peak
demand reduction requirements.
 Duke Energy Ohio will continue energy efficiency and peak demand reduction programs (Rider EEPDR).
 Duke Energy Ohio continues to purchase RECs and also enter contracts to comply with alternative
energy requirements.
