Section 7 — Regulation FD

Item 7.01. Regulation FD Disclosure.

On July 15, 2008, Exelon Corporation (Exelon) announced its comprehensive environmental plan that details an enterprise-wide approach and host of initiatives being pursued by Exelon to reduce Exelon’s greenhouse gas emissions and that of its customers, communities, suppliers and markets. A copy of Exelon’s 2020 Low Carbon Roadmap is available at Exelon’s website, <outbind://50/www.exeloncorp.com> www.exeloncorp.com. The press release announcing Exelon’s plan is attached as Exhibit 99.1.

Exelon currently estimates that the cost to implement the potential greenhouse gas abatement initiatives described in this plan would be in excess of $10 billion through 2020. Approximately 80-85% of the estimated cost is associated with various potential initiatives to offer more low-carbon electricity in the marketplace such as nuclear uprates, natural-gas plants, and renewable generation. The remaining 15-20% is associated with potential initiatives to reduce or offset Exelon’s Green House Gas (GHG) emissions and to help our customers reduce their GHG emissions. These estimates do not include the cost associated with a new nuclear plant if Exelon decides to build one. Actual expenditures will depend on economic and policy developments, and will be made on a project-by-project basis in accordance with Exelon’s normal project evaluation standards as the plan is implemented.
