Continues the current auction process for procuring supply for non-shopping load;

Addresses rate design issues for Riders RC and RE;

Includes provisions for improving reliability through a more aggressive capital expenditure program;

ESP effective June 1, 2015 through May 31, 2018.

SSO Supply

Auction follows same format as in previous ESP (i.e., descending clock). Delivery periods and auctions staggered. At least two auctions for each delivery period. Charles River & Associates to manage auction process. Excludes procurement of RECs to comply with renewable energy standards.

Full-requirements, load following for 100% of SSO or non-shopping load.

First set of auctions were held on May 14, 2015.

Continuation of Supplier Cost Reconciliation Rider (Rider SCR) to true-up SSO revenue with SSO supply costs.

SSO Pricing

Modified rate design on revenue neutral basis.

Simplified SSO rates and modify to more closely resemble market rates.

Eliminate demand charges for generation under all rate schedules so that all SSO generation rates are “energy-based,” mirroring what competitive retail electric suppliers typically offer shopping customers.

7

SSO Pricing Example - Eliminate Rider RC Demand Charges (Rate DS)

These are example rates. Actual Rider RC rates based on May 2015 auctions appear in the Company’s tariff.

8

Distribution Service

Distribution Capital Investment Rider (Rider DCI) Rider DCI provides for Duke Energy to implement a reliability improvement program

through more aggressive investment in our distribution system. Recovery of incremental capital spend over amounts currently in rates. Quarterly update filings and subject to annual audit by PUCO Staff. Modeled after similar riders approved for the FirstEnergy operating companies and for

AEP Ohio. Rider DCI will not recover any costs associated with Grid Modernization as long as

such costs are being recovered in a separate rider.

Distribution Storm Recovery Rider (Rider DSR) Tracks storm costs above/below baseline amount from rate case. Cost recovery begins if accumulated “above baseline” exceeds $5 million; otherwise,

factor “above/below baseline” into next rate case.

9

Other Provisions

Load Factor Adjustment Rider LFA will continue, but it will be reduced by 33 percent in the first year, 33

percent in the second year, and 34 percent in the third year. Effective June 2015, the credit is $0.013072 per kWh (periodically trued-up).

Large Customer Interruptible Load Program Will continue through the term of the ESP. Costs will continue to be recovered through Rider DR-ECF.

Use twelve months of demand and energy to develop an “average annual price to compare” for the best price comparison

Compare competing offers using the same usage data
