Results of Operations — ComEd

Three Months Ended June 30, 2024 Compared to Three Months Ended June 30, 2023. Net income increased by $21 million as compared to the same period in 2023, primarily due to timing of distribution earnings, higher transmission peak loads, and higher rate base. These were partially offset by a lower allowed ROE and the absence of a return on the pension asset.

Six Months Ended June 30, 2024 Compared to Six Months Ended June 30, 2023. Net income decreased by $26 million as compared to the same period in 2023, primarily due to a lower allowed ROE and the absence of a return on the pension asset. These were partially offset by higher transmission peak loads and higher rate base.

Revenue Decoupling. The demand for electricity is affected by weather and customer usage. Operating revenues are not impacted by abnormal weather, usage per customer, or number of customers as a result of revenue decoupling mechanisms.

Distribution Revenue. Distribution revenues were under a performance-based formula rate through 2023. Starting in 2024, distribution revenues are under a MRP. Both the performance-based formula rate and the MRP require annual reconciliations of the revenue requirement in effect to the actual costs the ICC determines are prudently and reasonably incurred with certain limitations for the MRP reconciliations.

revenue varies from year to year based upon fluctuations in the underlying costs, (e.g., severe weather and storm restoration), investments being recovered, and allowed ROE. Electric distribution revenues increased for the three months ended June 30, 2024 as compared to the same period in 2023, primarily due to differences in the timing of distribution earnings and higher rate base, partially offset by lower allowed ROE and the absence of a return on the pension asset. Electric distribution revenues increased for the six months ended June 30, 2024 as compared to the same period in 2023, primarily due to higher fully recoverable costs and higher rate base, partially offset by lower allowed ROE and the absence of a return on the pension asset.

Transmission Revenue. Under a FERC-approved formula, transmission revenue varies from year to year based upon fluctuations in the underlying costs, capital investments being recovered, and the highest daily peak load, which is updated annually in January based on the prior calendar year. Transmission revenues increased for the three months ended June 30, 2024 as compared to the same period in 2023, primarily due to the reclassification of the FERC audit liability, higher peak load, and and increases in underlying costs and capital investments. The favorable impacts due to the reclassification of the FERC audit liability are fully offset within Operating and maintenance expenses of the Consolidated Statements of Operations and Comprehensive Income. See Note 2 — Regulatory Matters for additional information regarding the FERC audit liability. Transmission revenues increased for the six months ended June 30, 2024 as compared to the same period in 2023, primarily due to higher peak load and increases in underlying costs and capital investments.

Energy Efficiency Revenue. Energy efficiency revenues are under a performance-based formula rate, which requires an annual reconciliation of the revenue requirement in effect to the actual costs the ICC determines are prudently and reasonably incurred in a given year. Energy efficiency revenue varies from year to year based upon fluctuations in the underlying costs, investments being recovered, and allowed ROE. Energy efficiency revenues increased for the three and six months ended June 30, 2024 as compared to the same periods in 2023, primarily due to increased regulatory asset amortization, which is fully recoverable.

Other Revenue primarily includes assistance provided to other utilities through mutual assistance programs. Other revenues increased for the three months ended June 30, 2024 and decreased for the six months ended June 30, 2024 as compared to the same periods in 2023, which primarily reflects increased and decreased mutual assistance revenues, respectively, associated with storm restoration efforts.

Regulatory Required Programs represents revenues collected under approved riders to recover costs incurred for regulatory programs such as recoveries under the credit loss expense tariff, environmental costs associated with MGP sites, ETAC, and costs related to electricity, ZEC, CMC, and REC procurement. ETAC is a retail customer surcharge collected and remitted to an Illinois state agency for programs to support clean energy jobs and training. The riders are designed to provide full and current cost recovery. The costs of these programs are included in Purchased power expense, Operating and maintenance expense, Depreciation and amortization expense, and Taxes other than income. Customers have the choice to purchase electricity from competitive electric generation suppliers. Customer choice programs do not impact the volume of deliveries as ComEd remains the distribution service provider for all customers and charges a regulated rate for distribution service, which is recorded in Operating revenues. For customers that choose to purchase electric generation from competitive suppliers, ComEd either acts as the billing agent or the competitive supplier separately bills its own customers, and therefore does not record Operating revenues or Purchased power expense related to the electricity. For customers that choose to purchase electric generation from ComEd, ComEd is permitted to recover the electricity, ZEC, CMC, and REC procurement costs without mark-up and therefore records equal and offsetting amounts in Operating revenues and Purchased power expense related to the electricity, ZECs, CMCs, and RECs.

See Note 4 — Segment Information of the Combined Notes to Consolidated Financial Statements for the presentation of ComEd's revenue disaggregation.

The increase in Purchased power expense of $78 million and $498 million for the three and six months ended June 30, 2024 compared to the same periods in 2023 is offset in Operating revenues as part of regulatory required programs.

Results of Operations — PECO

Three Months Ended June 30, 2024 Compared to Three Months Ended June 30, 2023. Net income decreased by $7 million, due to an increase in interest expense, depreciation expense, and credit loss expense, partially offset by an increase in revenue as a result of favorable weather.

Six Months Ended June 30, 2024 Compared to Six Months Ended June 30, 2023. Net income decreased by $24 million, due to an increase in storm costs, interest expense, depreciation expense, and credit loss expense, partially offset by an increase in revenue as a result of less unfavorable weather impact relative to the same period last year.

Weather. The demand for electricity and natural gas is affected by weather conditions. With respect to the electric business, very warm weather in summer months and, with respect to the electric and natural gas businesses, very cold weather in winter months are referred to as “favorable weather conditions” because these weather conditions result in increased deliveries of electricity and natural gas. Conversely, mild weather reduces demand. During the three months ended June 30, 2024 compared to the same period in 2023, Operating revenues related to weather increased due to favorable weather conditions in PECO's service territory. During the six months ended June 30, 2024 compared to the same period in 2023, Operating revenues related to weather increased due to less unfavorable weather conditions in PECO's service territory.
