__________ (a)Reflects a four-year cumulative multi-year rate plan for January 1, 2024 to December 31, 2027. On December 14, 2023, the ICC approved year-over-year distribution revenue requirement increases in 2024-2027, with an amendatory order on January 10, 2024, of approximately $451 million effective January 1, 2024, $14 million effective January 1, 2025, $6 million effective January 1, 2026, and $30 million effective January 1, 2027, based on an ROE of 8.905%, an equity ratio of 50%, and year end 2022 rate base. The ICC rejected ComEd’s Grid Plan, requiring ComEd to file a revised Grid Plan by March 13, 2024, 90 days after the issuance of the December final order. The ICC also directed that the revised Grid Plan would be reviewed through further formal proceedings in that docket. On January 10, 2024, the ICC granted one portion of ComEd’s application for rehearing of the December 14, 2023 final order, and directed that a rehearing process extending no more than 150 days reconsider certain components of the revenue requirements for the test years (2024-2027), absent an approved Grid Plan. On January 10, 2024, ComEd also filed with the Illinois appellate court an appeal of various aspects of the ICC’s final order on which rehearing was denied, including the 8.905% ROE and 50% equity ratio and denial of any return on ComEd’s pension asset. On March 13, 2024, ComEd filed its revised Grid Plan (Refiled Grid Plan) with supporting testimony and schedules with the ICC. On March 15, 2024, ComEd filed a petition to adjust its MRP to authorize increased rates consistent with the Refiled Grid Plan. (b)Reflects four-year cumulative increase to the revenue requirement approved on December 14, 2023 and amended on January 10, 2024 of $810 million for January 1, 2024 to December 31, 2027 resulting from the rehearing on certain components of the rate plan. On February 16, 2024, ComEd filed a revised revenue request for an $838 million increase in its 2024-2027 revenue requirements based on the ICC’s limited scope for rehearing which included the value of the 2023 forecasted year-end rate base. On April 18, 2024, the ICC issued an order on the rehearing filing which increased the revenue requirements previously approved by the ICC in its January 10, 2024, amendatory order by $150 million in 2024, $186 million in 2025, $221 million in 2026, and $253 million in 2027. ComEd anticipates that the revenue requirements determined during the rehearing process will be further adjusted upon approval of the Refiled Grid Plan and the pending petition to adjust rates. (c)On November 30, 2023, the Delivery Reconciliation Amount for 2022 defined in Rider Delivery Service Pricing Reconciliation (Rider DSPR) was approved. The delivery reconciliation amount allows for the reconciliation of the revenue requirement in effect in the final years in which formula rates are determined and until such time as new rates are established under ComEd’s approved MRP. The 2023 filing reconciled the delivery service rates in effect in 2022 with the actual delivery service costs incurred in 2022. The reconciliation revenue requirement provides for a weighted average debt and equity return on distribution rate base of 6.48%, inclusive of an allowed ROE of 8.91%, reflecting the monthly yields on 30-year treasury bonds plus 580 basis points. (d)Reflects a three-year cumulative multi-year plan for January 1, 2024 through December 31, 2026. The MDPSC awarded BGE electric revenue requirement increases of $41 million, $113 million, and $25 million in 2024, 2025, and 2026, respectively, and natural gas revenue requirement increases of $126 million, $62 million, and $41 million in 2024, 2025, and 2026, respectively. Requested revenue requirement increases will be used to recover capital investments designed to increase the resilience of the electric and gas distribution systems and support Maryland's climate and regulatory initiatives. The MDPSC also approved a portion of the requested 2021 and 2022 reconciliation amounts, which will be recovered through separate electric and gas riders between March 2024 through February 2025. As such, the reconciliation amounts are not included in the approved revenue requirement increases. The 2021 reconciliation amounts are $13 million and $7 million for electric and gas, respectively, and the 2022 reconciliation amounts are $39 million and $15 million for electric and gas, respectively. In April 2024, BGE filed with the MDPSC its request for recovery of the 2023 reconciliation amounts of $79 million and $73 million for electric and gas, respectively, with supporting testimony and schedules. (e)Reflects the amounts requested (before offsets) and awarded for a one-year multi-year plan for April 1, 2024 through March 31, 2025. The MDPSC awarded Pepco an electric incremental revenue requirement increase of $45 million for the 12-month period ending March 31, 2025. The MDPSC did not adopt the requested revenue requirement increases of $80 million (before offsets), $51 million, and $14 million as filed for 2025, 2026, and the 2027 nine-month extension period, respectively. The order allows for Pepco to perform an annual reconciliation after the 2024 rate year. The MDPSC also approved the requested reconciliation amounts for the 12-month periods ending March 31, 2022, and March 31, 2023, which will be recovered through a rider between August 2024 through March 2026. As such, the reconciliation amounts are not included in the approved revenue requirement increases. The reconciliation amounts are $1 million, and $7 million, for the 12-month periods ending March 31, 2022, and March 31, 2023, respectively. In July 2024, Pepco filed its request with the MDPSC for recovery of $31 million for the 12-month period ended March 31, 2024, with supporting testimony and schedules. (f)Reflects a three-year cumulative multi-year plan for January 1, 2023 through December 31, 2025. The MDPSC awarded DPL electric incremental revenue requirement increases of $17 million, $6 million, and $6 million for 2023, 2024, and 2025, respectively. (g)On April 18, 2024, the DEPSC approved the Significant Storm Expense Rate Rider (Rider SSER) which will allow DPL to recover expenses associated with qualified storms. A qualified storm will be an individual storm for which DPL incurs expenses between $5 million and $15 million. The Rider SSER allows DPL to recover significant storm damage expenses for the previous 12-month period over a future 24-month period. For individual storm events for which DPL incurs expenses of more than $15 million, the future recovery period will be evaluated on a case-by-case basis and the unamortized balance will earn a return at DPL's authorized long-term cost of debt. The Rider SSER will have an annual true-up filing, subject to DEPSC review and approval. (h)Requested and approved increases are before New Jersey sales and use tax. The NJBPU awarded ACE electric revenue requirement increases of $36 million and $9 million effective December 1, 2023 and February 1, 2024, respectively.

__________ (a)On March 13, 2024, ComEd filed its Refiled Grid Plan with the ICC and on March 15, 2024, ComEd filed a petition to adjust its multi-year rate plan to be aligned with ComEd’s Refiled Grid Plan. The adjusted rate plan incorporates changes in the Refiled Grid Plan, which was updated in ComEd's July 31, 2024 surrebuttal testimony and updated again on August 13, 2024, to request a $667 million increase in revenue requirements over four years above those granted in the ICC’s January 10, 2024 amendatory order. The requested year-over-year increases are $309 million in 2024, $95 million in 2025, $128 million in 2026, and $135 million in 2027. A final order on both the Refiled Grid Plan and the adjusted rate plan petition is expected by December 2024 with new rates effective on or before January 1, 2025. (b)On April 26, 2024, ComEd filed its proposed Delivery Reconciliation Amount, which was updated in ComEd's surrebuttal testimony on September 11, 2024, of $624 million under Rider DSPR which allows for the reconciliation of the revenue requirement in effect. The 2024 filing reconciles those rates with the actual delivery service costs incurred in 2023. The final order is expected in the fourth quarter of 2024 and the reconciliation amount will adjust customer rates in 2025. (c)PECO requested an annual electric revenue requirement increase of $464 million, which is partially offset by a one-time credit of $64 million in 2025. (d)On August 30, 2024, PECO and the settling parties filed with the PAPUC two petitions for non-unanimous joint settlements, which included among other things, an increase of $354 million and $78 million in annual distribution service revenue for electric and gas, respectively. No overall ROE was specified in either settlement. On October 15, 2024, the Administrative Law Judges (ALJs) issued Recommended Decisions approving the requested revenue increases of $354 million for electric and $78 million for gas. On October 22, 2024, PECO filed an exception to the ALJs ruling against the Gas Weather Normalization Adjustment. The Commission’s final order, addressing the exception, is expected by December 2024. If approved, the new electric and gas rates take effect January 1, 2025. (e)Reflects a three-year cumulative multi-year plan for January 1, 2024 through December 31, 2026 submitted to the DCPSC. Pepco requested total electric revenue requirement increases of $116 million, $35 million, and $35 million in 2024, 2025, and 2026, respectively. Requested revenue requirement increases will be used to recover capital investments designed to advance system-readiness and support the District of Columbia’s climate and clean energy goals. (f)DPL can implement interim rates on April 20, 2025, subject to refund.

__________ (a)All rates are effective June 1, 2024 - May 31, 2025, subject to review by interested parties pursuant to review protocols of each Utility Registrants' tariffs. (b)Represents the weighted average debt and equity return on transmission rate bases. For PECO, the common equity component of the ratio used to calculate the weighted average debt and equity return on the transmission formula rate base is currently capped at 55.75%. (c)The rate of return on common equity for each Utility Registrant includes a 50-basis-point incentive adder for being a member of an RTO. (d)The increase in BGE's transmission revenue requirement includes a $2 million reduction related to a FERC-approved dedicated facilities charge to recover the costs of providing transmission service to specifically designated load by BGE.
Public Utilities Energy Efficiency Revenue [Table Text Block] | ComEd filed its annual energy efficiency formula rate update with the ICC on May 30, 2024. The filing establishes the revenue requirement used to set the rates that will take effect in January 2025 after the ICC's review and approval. The requested revenue requirement update is based on a reconciliation of the 2023 actual costs plus projected 2025 expenditures. The ICC's final order is expected in the fourth quarter of 2024.
Initial Revenue Requirement Increase |  | Annual Reconciliation Decrease |  | Total Revenue Requirement Increase |  | Requested Return on Rate Base(a) |  | Requested ROE
$ | 66 |  |  | $ | (8) |  |  | $ | 58 |  |  | 7.02 | % |  | 9.89 | %
__________ (a)The requested revenue requirement increase provides for a weighted average debt and equity return on the energy efficiency regulatory asset and rate base of 7.02% inclusive of an allowed ROE of 9.89%, reflecting the monthly average yields for 30-year treasury bonds plus 580 basis points. For the 2023 reconciliation year, the requested revenue requirement provides for a weighted average debt and equity return on the energy efficiency regulatory asset and rate base of 7.25% inclusive of an allowed ROE of 10.34%, which includes an upward performance adjustment that increased the ROE. The performance adjustment can either increase or decrease the ROE based upon the achievement of energy efficiency savings goals.
