Question: Can Duke Energy Ohio, Inc. provide guidance on how it calculated the Peak Load Share (PLC) reflected in the November 8, 2011 Bidder Information Session presentation?

Answer: Duke Energy Ohio, Inc. calculates PLCs for all customers on its system using the 5 CP method. Suppliers can determine PJM's 5 peaks from data available at: http://www.pjm.com/markets-and-operations/energy/real-time/loadhryr.aspx.  From this information, suppliers can use the 5 PJM peak hour date/times and get each customer class peak coincident with the PJM peaks from data available at: http://www.duke-energyohiocbp.com/Documents/LoadandOtherData.aspx, by accessing the Historical Hourly Loads by Class file. Suppliers can then use scaling factors and other required values currently in effect to estimate the PLC for each customer class.  For more information on how all the PLC calculations work, please see PJM Manual 18, available at: http://pjm.com/~/media/documents/manuals/m18.ashx.

Published On: 12/05/2011

Question: The November 28, 2011, News item states: “based on historical data, the energy obligation is approximately 16.47 MW per tranche”. This is based on the 5 CP method. However, the SSO load obligation continually changes as a result of migration to CRES suppliers. So does the 16.47 MW represent the SSO obligation (and migration level) as of November 28th or some other date?

Answer: The information was based upon the 2010 5 CP data and enrollments as they existed on August 1, 2011.

DAT 00026
Published On: 12/06/2011

Question: How does Duke Energy Ohio, Inc. calculate PLCs for interval metered and non-interval metered customers?

Answer: The following methodology is used to calculate PLCs for interval metered and non-interval metered customers:

  • Duke Energy Ohio, Inc. calculates individual PLCs for all customers on the system.
  • A customer may be an individual retail customer, or a large discreetly metered municipality.
  • In all, there are approximately 700,000 customers for whom PLCs are calculated.
  • Duke Energy Ohio, Inc. utilizes customer load at the time of the 5 CPs provided by PJM as the basis for the PLC calculation.
  • Demand Response provided by customers is added back to their hourly load values prior to making the PLC calculation, if that customer is claiming that demand response as capacity (this includes behind the meter generation).
  • Duke Energy Ohio, Inc. utilizes the weather normalized peak value provided by PJM, as the basis for its weather normalization factor (the average of the 5 system peaks is scaled to be equal to the W / N peak provided by PJM).
  • Duke Energy Ohio, Inc. uses a bottom up methodology to calculate loads on the system. Interval metered customer load is directly measured. Non-interval customer loads are calculated by using load profiles produced from load research meters, and usage factors developed by comparing each customer’s usage to average of their rate class (RS, DS, DM, etc.).
  • Duke Energy Ohio, Inc. applies Transmission and Distribution losses to the customer loads.
  • Duke Energy Ohio, Inc. calculates unaccounted for energy on the system by comparing the bottom up load, plus losses, to the system load (generation minus metered ties). UFE is allocated to all non-interval metered customers on a load ratio share basis.
  • The proceeding methodology calculated a customer load for each hour. Loads for the 5 CPs are averaged, and subsequently adjusted by the weather normalization factor to produce a PLC.

Published On: 12/08/2011

Question: In the “Customer Counts” file as provided on the Information Website, the data description states that the customer counts are based on data for the 12 months ended [DATE]. Does this mean that customer counts are averaged over the most recent 12 months? Also, do the counts include all customers within the Duke Energy Ohio, Inc. service territory or only those currently being served by the default service?

Answer: The TOTAL NUMBER OF ACCOUNTS rows are the counts as of [DATE]. The size breakdowns (e.g., NO ACCOUNTS GREATER THAN 500 KW) are based on the period October 2010 through 2011. These rows represent the number of accounts with at least one billed monthly demand greater than or less than 500 kW.

The counts include all customers within the Duke Energy Ohio, Inc. service territory, i.e., shopper and non-shopper.

Published On: 12/08/2011

Question: In response to DAT 00003, Duke Energy Ohio, Inc. states that suppliers can use historical customer class data during the 5 PJM peak hours in order to estimate the PLCs. However, in response to PJM 00005, Duke Energy Ohio, Inc. states that it will be calculating weather normalized peaks. Can you please help reconcile the difference between these two responses?

Answer: There is no discrepancy in the responses. Suppliers can use historical data during the 5 PJM peak hours to estimate PLCs. Insofar as it concerns Duke Energy Ohio, Inc.'s methodology, Duke Energy Ohio, Inc. also uses a weather normalized factor. Further reference is made to DAT 00026, which describes the methodology used by Duke Energy Ohio, Inc. to calculate PLCs for interval metered and non-metered customers.

Published On: 05/21/2012

Question: In regards to the answer provided for the question DAT 00039, why will Duke not provide available PLC information? Auctions held in other states, as well as in Ohio, provide both current and historical PLC data for eligible and SOS load as well as current and historical NSPL data for eligible and SSO load. Other auctions also provide the next planning year's PLC and NSPL as soon as the data is available. This data is very helpful to suppliers and estimating the PLC only from hourly data will impact the price paid by ratepayers.

Answer: Duke Energy Ohio, Inc. only calculates PLC data historically. Duke Energy Ohio does not calculate the PLC until the end of each calendar year. Suppliers can perform the calculation with the data provided if they wish to do so.  See answers to questions previously provided in DAT 00003 and DAT 00039.

DAT 00042
Published On: 05/21/2012

Question: Is the increase in Standard Offer RS customers between January 1, 2012 and February 28, 2012 driven by government aggregation contracts expiring and customers from the affected communities returning to Standard Offer Service?

Answer:  Yes.

DAT 00044
Published On: 09/14/2012

Question: What are government aggregation contracts and is there a timeline for when these contracts expire?

Answer: Ohio law allows governmental entities to aggregate qualifying load within their jurisdictional boundaries. The requirements applicable to such aggregations may be found in the Ohio Revised Code and the Ohio Administrative Code. A governmental entity that proceeds, through aggregation, to arrange for supply with a competitive supplier would likely enter into a contract for that supply. Duke Energy Ohio is not a party to such contracts and thus cannot comment on the terms and conditions of same. Duke Energy Ohio further observes that such contracts should be a matter of public record.
