Question: Can you explain the jump in migration in the Penelec Commercial Customer Class in January 2011 (migration went from 10% to 35% in that one month)? Was there a PUC mandate, or expiring contracts, or some other factor that induced customers to switch during that time period?

Answer: Generation Rate Caps ended on 12/31/2010, and rates associated with the Default Service that started 1/1/2011 reflected market-based pricing.  Commercial customer shopping increased during this time period.

Question: The historical load data are unadjusted for Unaccounted for Energy (UFE) and deration. Therefore, to determine the amount that a Default Service supplier must deliver and gets paid for (which are equal) in the historical data, you first add the load ratio portion of UFE to each class, and then scale that number by the deration factor. This represents a Default Service supplier's obligation and volume that will be paid on. Is this correct?

Answer: Effective June 1, 2015, in accordance with the PA PUC orders in P2013-2391368, P2013-2391372, P2013-2391375 and P2013-2391378, the PA utilities will be responsible for total UFE and no longer allocate UFE to LSE loads.  A Default Service supplier should no longer add the load ratio portion of UFE to each class’ historical load data to determine its amount of load delivered. Simply apply the deration factor to the historical hourly class loads (which include T&D losses and exclude UFE) to determine energy volumes for delivery and payment.

Question: We have adjusted the Peak Load Contribution (PLC) data provided for each Company on the Auction Information Website with the Daily Zonal Scaling Factors also provided. When we compare our adjusted PLCs to those published by PJM for each Company they do not reconcile. If 100% of the customers are on Default Service, these two numbers should be very close. Why does this occur and how can we reconcile these numbers?

Answer: The load data posted on the PJM Website include wholesale load, which is not included in the Default Service load used in this procurement.

Question: In the Shopping Statistics data file, the implied number of total (shopping plus non-shopping) customers for the Commercial customers and Industrial customers increases substantially, from ~95,563 and ~129 respectively as of April 1, 2012, to ~114,986 and ~624 respectively as of July 1, 2012, using the provided %'s and number of customers served by an AS. Is this in fact correct, and if so, could you perhaps explain why this is occurring?

Answer: The July 1, 2012 statistics for West Penn Power Commercial and Industrial customers reflect the integration of West Penn Power with its sister FirstEnergy PA utilities following the Allegheny Energy/FirstEnergy merger.  The statistics now are reported from the same FirstEnergy systems and on the same basis as Met-Ed, Penn Power, and Penelec.  The Commercial statistics represent the combination of Types 20 and 30 and now include street light counts, which are reflected in increased total counts.  The Industrial statistics include Type 40, including Schedule 30 Large (greater than 500 kW), which is reflected in the increased in customer counts.

Question: In the provided hourly load data files, the data are broken up between residential, small commercial, and large commercial. The descriptions do not directly correlate with the data definitions provided in the "Data_Description_Document.pdf". Can you provide what rate schedules make up the small commercial data as well as the large commercial data, or explicitly state what customer class the data series correlate with in the data description document?

Answer: The small commercial and large commercial nomenclature appears only in the Penn Power hourly load profile data file.  The small commercial data align with Penn Power Commercial in Section II B of the Data Description document, and large commercial data align with the Penn Power Industrial in the Data Description document.  This has been revised to alleviate any further confusion.

Question: It is my understanding that the PLCs that FirstEnergy submits to PJM have already been scaled by the Daily Zonal Scaling Factors provided in the Data Room (i.e., the "Load and Other Data" page under Documents on the FEPA Auction Information Website). Therefore, PJM’s Zonal Scaling Factors as posted in PJM’s eRPM eSuite are equal to one. However, when I take the 5/31/2013 PENELEC Commercial Capacity PLS value posted on the FEPA Auction Load and Other Data page ( of 275.093 MW and multiply that value by the 5/31/2013 PENELEC Daily Zonal Scaling Factor of 89.781%, I get a value of 247.708 MW. Using our share of the PENELEC commercial load on 5/31/2013, the computed PLC is not equal to the value posted in eRPM for 5/31/2013. Is there another daily factor that is applied to the PLC outside of the Daily Zonal Scaling Factor prior to uploading the values to PJM?

Answer: The PLCs submitted to PJM already have been scaled by the Daily Zonal Scaling Factors as provided on the "Load and Other Data" page. Please note that the raw PLC values when scaled may not match those posted to PJM eRPM because they are created on a monthly basis after the fact.  The data on the "Load and Other Data" page are not intended, nor should they be used, to verify or validate the values posted to PJM.

Question: The Met-Ed file containing Daily Zonal Scaling Factors for Network Transmission Service Peak Loads ("NSPLs") begins with data from 12/1/2012. Are there historical data available prior to this date? Also, can you explain the significant difference between the factor on 12/31/2012 and on 1/1/2013?

Answer: We added the NSPL daily zonal scaling factors to the load data postings starting December 2012.  We are unable to create these data historically.  The significant difference in NSPL Daily Zonal Scaling factors between December 31 and January 1 is due to newly assigned NSPL tickets , as well as a new PJM zonal NSPL target, that are effective each January 1.

Question: We looked at the historical load data on the "Load and Other Data" page under documents on the Information Website. For Penelec and Met-Ed, sometimes hourly load is significantly higher than for the previous hour and following hour. For example, in the Penelec hourly load data file, on 12/22/2013, hour 10, both shopped and non-shopped residential load is almost 3 times higher than the load in hour 9. The same load jump also is found for 9/5/2014-Hr12 and for some days in Sept 2010. The issue also exists in the Met-Ed load data (9/11/2013-Hr10). Is this a data error?

Answer: Residential loads, more so than commercial and industrial loads, are weather-sensitive and respond to temperature fluctuations.  9/5/2014 was one of PJM's five critical peak days in both Penelec and Met-Ed as energy demands were at their highest.  Temperatures were above normal this day, especially compared to other days during the summer, and residential loads responded in kind.  The data have been reviewed and are accurate.  Additionally, extreme weather conditions on 12/22/13 also would explain the residential load jump at hour 10.  When weather conditions are extreme, the customer class load diversity decreases significantly as many residential customers turn on their A/C or heat simultaneously, depending on the season.

Question: The loss factors are provided by schedules, and without class information that gives us the make-up of each class, we cannot develop a properly weighted loss factor. Can you provide us with either the load data applicable by schedule or the applicable weighted loss factors for the different classes?

Answer: The load data posted on the Information Website are by class type with losses.  The purpose of the data specifically is to provide potential Default Service Suppliers with the information needed to competitively bid to serve non-shopped load available for Met-Ed, Penelec, Penn Power, and West Penn.  These are the data posted to PJM used for billing Default Service Providers and also used to create the EDC invoice to pay Suppliers for purchased power.  While we agree the class type load data do not provide the granularity needed to determine a weighted loss factor, we do not agree that there is a need to determine a weighted loss factor for each class type in order for Default Service Suppliers to competitively price this product since the aggregated load by class with losses is provided.

Question: For West Penn Power load data, I noticed an increase in both shopping and non-shopping commercial load starting around 6/1/2015 (what looks like around 30 MW for non-shopping and 50 MW for shopping). Is there a reason for this, or is this an error in the data?

Answer: We verified the accuracy of the data.  When compared to June 2014 average loads, there was very little change in the commercial class year-over-year; less than a 1% decrease in commercial non-shopping load and about a 2% increase in commercial shopping load.  Seasonal changes may influence increased load patterns from month to month; May is generally considered a shoulder month with moderate swings in temperature and load usage versus June which is a warmer weather month with higher consumption.

Question: For Penn Power small commercial/industrial (SCI) Default Service, PLC dropped about 10MW (~10%) in June 2015. What is the reason behind the drop in PLC during June 2015?

Answer: The posted peak load contribution (PLC) values are unscaled values.  Penn Power's actual load contribution to the 2014/2015 five coincident peak periods (5 CPs) was above target and the zone's actual load contributions to the 2015/2016 5 CPs were below target due to mild summer weather.  If the daily zonal scaling factor is applied to the posted PLC values for May 31 and June 1 (0.98 and 1.02, respectively), you will find that the scaled PLC values are in line.

Question: In order for a Default Service Supplier to estimate their capacity obligation, do they need to scale the hourly load data found on the "Load and Other Data" page under Documents on the Information Website by the reconciliation factors for the applicable delivery year? Or have the hourly load data on the "Load and Other Data" page already been scaled by these factors?

Answer: The reconciliation factors referred to are applied to a customer's metered load with losses to determine a customer's peak load contribution (PLC) value.  Applying these factors to the hourly data posted on the "Load and Other Data" page would estimate a PLC value not capacity obligation.  To determine capacity obligation, apply PJM's UCAP conversion factor and the daily zonal scaling factor to the class type PLC values.  Both the daily zonal scaling factor and the class type PLC values can be found on the "Load and Other Data" page at  The PJM's UCAP conversion factor is the ratio of the respective zone's Final Zonal UCAP to the Base Zone WN Summer Peak.  These values can be found in PJM"s eRPM.  The UCAP conversion factor typically is around 15%.

Question: Can you please explain why in the Capacity and Transmission PLC by Rate (PP_Cap_Trans_PLS) file, PennPwr Non-Shopped NSPL increased 6 times from 12/31/2016 to 1/1/2017?

Answer: The large increase in the Penn Power Industrial customer class NSPL is due to a 15 MW Industrial customer that became active last year and was assigned a default Transmission PLC value less than 1 MW at that time.  The 2017 Transmission PLC calculation used this customer's actual load data, increasing its Transmission PLC from less than 1 MW in 2016 to 14.6 MW effective Jan 1, 2017.  A similar change occurred with the Capacity PLC value assigned to this customer effective June 1, 2017.

Using West Penn Power as an example, FAQ GEN 00060 gives the transmission loss component as 0.02184. When I look at the West Penn Power Supplier Tariff, I can see 2.184% as the on-peak line losses for Transmission Voltage under the Company Line Loss Factor Rider. The off-peak line losses are 1.938%. Rider H in the West Penn Power Electric Tariff states that the Loss Factor for the Commercial Customer Class is 1.0899 and for the Residential Customer Class is 1.0910. Can you please provide me with the correct calculation I need to do in order to get the correct load at the retail meter? It is my understanding that all residential load should be at a Secondary voltage, and there are different percentages for this. For example the West Penn Power Supplier Tariff states 9.434% and 8.537% for on-peak and and off-peak. What should I do about this?
