Question: When will you post the PLC for Residential & Street Lighting and Small C&I?

Question: For the Historical PLC_NSPL_MW-Day spreadsheets. Is that the PLC/NSPL for the 1st of the month? For example, column A, has the dates listed as 1/1/2018 to 2/1/2017. Are the PLCs an average of the month or only for that specific day listed?

Answer: The Historical PLC_NSPL_MW Day values in the spreadsheets are actual values from the last day of the month of the date shown in column A .

Question: In the "Historical Load HPS 2015-2016" load data file, unlike other load data, it doesn't split default and egs load data. Are they all default load, egs load or total load?

Answer: The load data provided is Historical Load for HPS customers that have been on default service during the period of time shown.  This load represents a small percentage (2-3%) of the total load that is not being serviced by EGSs (Retail Suppliers).  For this customer class, the amount of customers and load has been, historically, consistent and lacks the switching aspect of the other default service customer classes.  We did not provide the EGS served load at this time but are considering ways to provide this data in the future.

Question: Are the PLC and NSPL in the dataroom scaled by daily zonal scaling factor. Do we need to apply PJM RPM daily zonal scaling factor to get the PJM daily PLC?


Our daily uploaded PLC always matches the Base Zonal Weather Normalized Summer Peak. PJM does not need to apply a scaling factor.


Our daily uploaded NSPL always matches the expected target value.


The PLC and NSPL provided for the auction represent the portion of the uploaded PLC and NSPL for the rate class.

Question: Can you please provide the LC&I historical PLC data for the same time frame as the other rate classes? Other rate classes have PLC data back to 2008 but the LC&I data is only Feb 2017.

Answer: Duquesne Light Company was able to provide the data from 2015 and 2016 for the large C&I customers.  While this is a different time period of data than was provided for the other market segments, we're hopeful that 2 years of data information will be sufficient.

Question: Could you post the most current PLC tags for the Medium C&I customers for the 2017/2018 Planning Year? Without that data being publicly posted to all bidders, then any bidder who is also a current supplier has an unfair informational advantage by knowing how tags were reset for the new Planning Year.

Answer: Additional data for the Medium C&I customers has been posted.  The most recent data includes the June PLC value for the Medium C&I load.

Question: Looking at the customer count data for RES & SL (“Historical Loads 2011-2017 Residential and Lighting” file, “Customer Counts” tab), there is a steep reduction on customers count on both POLR LT and EGS LT. Total Customer count for both categories was 8,249 in May 2014 reducing to 985 by Dec 2014. Any insight on what drove the decrease on customer count?

Answer: During the period in question, May 2014 through December 2014, Duquesne Light Company was putting into production a new billing platform.  The integration of that new billing platform lead to the consolidation of accounts, as we shifted to a different account number/SA ID format, and the retirement of accounts that were found to be unnecessary to integrate into the new system.  The billing system was fully implemented in Q4 2014.  The numbers provided for 2017 are deemed to be accurate and should be used.
