FAQ-76:
Is PECO's NYPA allocation for energy year 2025/26 available?
PECO will not have this information prior to the Bid Date for the March 2025 Solicitation. PECO’s NYPA allocation for the 2024/25 energy year is 5.848 MW and this is the latest information available. For more information about PECO’s arrangement with the New York Power Authority, please refer to slide 30 of the Bidder Information Webcast available on the Supplier Information – Documents page of the RFP website. Specifically, please note that the allocation is dependent upon the number of residential customers PECO serves.

FAQ-75:
The UFE data on the RFP Website is on average positive for 2024 and was on average negative in prior years. Does PECO know the reason for this change? Is the data correct? Is PECO using updated profiles?
The Unaccounted for Energy (“UFE”) data posted on the RFP Website is correct. PECO is not using updated load profiles for 2024. The UFE data report on the RFP website is the hourly MW difference between PECO’s total retail hourly energy (system load) and the estimated hourly customer loads (both interval metered and profiled). If UFE is positive than PECO’s total retail hourly energy (system load) is greater than the estimated hourly customer loads (both interval metered and profiled). There are various causes of UFE, which are not limited to but may include the following:- Electrical losses: Energy lost in the transmission system
- Metering errors: Inaccurate readings from meters
- Unmetered connections: Unmeasured electricity use from items like streetlights and traffic signals
- Energy theft: Electricity that is stolen or used without being registered
Please note that the hourly load data in the Data Room has already been adjusted to include UFE. PECO allocates UFE to all Load Serving Entities in the PECO zone (i.e., to EGS and default service Load Serving Entities) each month based on load-ratio share. Prior to March 2015 UFE is allocated to monthly-metered customers and not to hourly/interval metered customers. Starting in March 2015 UFE is allocated to all customers, including hourly/interval metered customers.

FAQ-48:
The hourly load data file posted in the data room for the small commercial group is missing data from 2/1/2024 through 5/31/2024 for the AL rate class. Can PECO post this missing data?
Hourly load data for the AL rate class is not currently available due to an internal system issue that is specific to this rate class. PECO is investigating this issue. There is currently one customer on the AL rate class, and that customer is not a default service customer.

FAQ-47:
In the hourly load data file, for the CCI-GS rate schedule, the Default Energy (MWh) is negative for hours 10-13 on 10/27/2017. Also, for those same hours, in the Unaccounted For Energy (UFE) file, the Total Zone UFE (MW) is positive. Please confirm that the data is correct.
The values provided for the Default Energy (MWh) for the CCI-GS rate schedule and the Total Zone UFE in hours 10-13 on 10/27/2017 should be disregarded due to metering error.

FAQ-46:
In the hourly load data file, for the CCI-HT rate schedule, the Default Energy (MWh) values from 3/1/2024 to 3/5/2024 are negative. Can you please confirm whether the data is correct?
The values from 3/1/2024 to 3/5/2024 in the file “PECO_CCI_Hourly_Load.xlsx” on tabs ‘CCI Total Hourly Load’ and ‘CCI-HT Hourly Load’ should be disregarded due to an error in the data.

FAQ-43:
What is PECO’s two-step process to settle the hourly load obligations with each LSE and PJM?
PECO settles hourly load obligations with each LSE and PJM via a two-step process:- Settlement A – PECO determines the estimated “day after” (delivery day) hourly load responsibility by recreating the load characteristics of the delivery day in question using a combination of available known, preliminary, and historically-based information. PECO then submits the load responsibility for all LSEs serving load on the settled day(s) to PJM in accordance with PJM procedural requirements and energy market schedules.
- Settlement B – PECO determines the final hourly load responsibility approximately 60 days after an energy delivery month by reconciling actual individual customer meter readings and applicable load profile data with the Settlement A data for that month. PECO then calculates and submits the energy variances from Settlement A hourly scheduling for all LSEs to PJM in accordance with PJM procedural requirements and energy market schedules.
PECO provides an overview of the determination of hourly load obligations on their website here: https://electricandgaschoice.force.com/s/article/Determination-of-Hourly-Load-Obligations-Overview

FAQ-42:
What data is available related to the NYPA agreement?
PECO receives an annual allocation of capacity and associated energy from the New York Power Authority and uses this allocation to offset the amount of supply needed for the Residential Class. As confirmed in FAQ-15, “Default Load for the Residential Class is reduced by a fractional percentage of committed energy and capacity obtained under contract with Allegheny Electric Cooperative, Inc. for supply from the New York Power Authority (“NYPA”). Default Suppliers are not responsible for providing any of the services or products included in full requirements service for NYPA supply.”The annual allocation from NYPA is dependent on the number of residential customers PECO serves. PECO’s allocation for energy year 2024/25 is 5.848 MW. There is no other historical data available for the NYPA agreement on the RFP website.
Please see FAQ-37 for how data in the Data Room is handled in regard to NYPA.
