Section 2 – Financial Information
Item 2.05 Costs Associated with Exit or Disposal Activities

On August 27, 2020, Exelon Generation Company, LLC (Generation) announced that it intends to permanently cease generation operations at Byron Generating Station (Byron) in September 2021 and at Dresden Generating Station (Dresden) in November 2021. The current Nuclear Regulatory Commission (NRC) licenses for Byron Units 1 and 2 expire in 2044 and 2046, respectively, and the licenses for Dresden Units 2 and 3 expire in 2029 and 2031, respectively. A copy of the press release is attached hereto as Exhibit 99.1.

The primary factors contributing to the deteriorating economic value of Byron and Dresden include significant declines in plant revenues due to prolonged periods of low wholesale power prices, market rules that allow fossil fuel plants to underbid clean resources in the PJM capacity auction, and the absence of federal or state policies that place a value on nuclear energy for its ability to produce electricity without carbon or air pollution while contributing to grid reliability and resiliency. All of these factors contribute to deteriorating economic value and losses for the foreseeable future.

As a result of the decision to early retire Byron and Dresden, Exelon Corporation (Exelon) and Generation will recognize certain one-time charges in 2020 ranging from an estimated $200 million to $300 million related to materials and supplies inventory reserve adjustments, employee-related costs, and construction work-in-progress impairments, among other items. Exelon and Generation also could recognize additional one-time charges in 2021 not expected to exceed $50 million. These one-time charges will be excluded from Exelon’s and Generation’s Adjusted (non-GAAP) Operating Earnings. Estimated total cash expenditures related to the one-time charges primarily for employee-related costs are expected to range from less than $25 million in 2020, $25 million to $50 million in 2021, and $50 million to $100 million thereafter.

In addition to these one-time charges, there will be ongoing annual financial impacts stemming from shortening the expected economic useful lives of Byron and Dresden primarily related to accelerated depreciation of plant assets (including any asset retirement costs (ARC)), accelerated amortization of nuclear fuel, and changes in asset retirement obligation (ARO) accretion expense associated with the changes in decommissioning timing and cost assumptions to reflect an earlier retirement date. The following table summarizes the estimated annual amount and timing of expected incremental non-cash expense items expected to be incurred as a result of the intended early retirement, which will also be excluded from Exelon’s and Generation’s Adjusted (non-GAAP) Operating Earnings.

(a)Includes the accelerated depreciation of plant assets including any ARC.
(b)Based on the regulatory agreement with the Illinois Commerce Commission for the former Commonwealth Edison Company (ComEd) units, decommissioning-related activities are offset within Exelon’s and Generation’s Consolidated Statements of Operations and Comprehensive Income and the offset results in an equal adjustment to the noncurrent affiliate payable/receivable between Generation and ComEd and the regulatory liabilities recognized at ComEd. Should the expected value of the NDT fund for any former ComEd unit fall below the amount of the expected decommissioning obligation for that unit, the accounting to offset decommissioning-related activities at Generation for that unit would be discontinued and the decommissioning-related activities would be recognized in Exelon’s and Generation’s Consolidated Statements of Operations and Comprehensive Income, the adverse impact of which could be material.

Upon retirement, Dresden will have adequate funding assurance, however, due to the earlier commencement of decommissioning activities and a shorter time period over which the nuclear decommissioning trust fund (NDTF) investments could appreciate in value, Byron may no longer meet the NRC minimum funding requirements and, as a result, the NRC may require additional financial assurance including possibly a parental guarantee from Exelon. However, the amount of any required financial assurance would ultimately be dependent on the decommissioning approach adopted at Byron, the associated level of costs, and the decommissioning trust fund investment performance going forward. Within no later than two years after shutting down a plant, Generation must submit a

post-shutdown decommissioning activities report to the NRC that includes the planned option for decommissioning the site. Considering the different approaches to decommissioning available to Generation, the most likely estimates currently anticipated could require financial assurance for radiological decommissioning at Byron of up to $325 million.

Upon issuance of any required financial guarantees, each site would be able to utilize the respective NDTFs for radiological decommissioning costs, which represent the majority of the total expected decommissioning costs. However, under the regulations, the NRC must approve an exemption in order for Generation to utilize the NDTFs to pay for non-radiological decommissioning costs (i.e. spent fuel management and site restoration costs, if applicable). If a unit does not receive this exemption, those costs would be borne by Generation without reimbursement from or access to the NDT funds. Accordingly, based on current projections of the most likely decommissioning approach, it is expected that Dresden would not require supplemental cash from Generation, but some portion of the Byron spent fuel management costs would need to be funded through supplemental cash from Generation. While the ultimate amounts may vary and could be offset by reimbursement of certain spent fuel management costs under the United States Department of Energy settlement agreement, decommissioning for Byron may require supplemental cash from Generation of up to $175 million, net of taxes, over a period of 10 years after permanent shutdown.
