                             Federal Regulatory and
                             Legislative Activities

- -  Update on Congressional action on Yucca Mountain Waste Repository
- -  Update on energy policy legislation
- -  FERC's policy initiatives




                                                               [Logo for Exelon]

                                 Yucca Mountain

- -  Congress is nearing final action on Yucca Mountain waste repository
   -- President Bush recommended approval Feb.15
   -- Governor Guinn exercised Nevada's "veto" authority under the statute
   -- House of Representatives overwhelmingly approved a resolution to override
      the veto on May 8 (306-117)
   -- Senate Committee approved the resolution 13-10
   -- Senate will consider by July 25; simple majority required
   -- If approved, DOE will seek license from NRC; lengthy regulatory
      proceedings




                                                               [Logo for Exelon]

                            Energy Policy Legislation

- -  House of Representatives passed major energy policy bill last year
- -  Senate passed a bill after 6 weeks of debate
- -  Conferees have finally been appointed
- -  Huge job ahead resolving differences (1,000+ pages!)
- -  Senate electricity provisions have bipartisan support; generally positive
   impact
   -- PUHCA repeal
   -- PURPA repeal
   -- Clear FERC authority over munis & coops to require open access
   -- Negatives: Renewal Portfolio Standard; more FERC review of asset transfers
      (including generation)
- -  Prospects for enactment are uncertain



                                                               [Logo for Exelon]

                      FERC: Focus on Wholesale Competition

- -  Developing "Standard Market Design"
- -  Reconsidering how to measure if a utility has market power
- -  Reconsidering standards governing market-based rate authority
- -  Redefining rules for Regional Transmission Organizations (RTOs)
   -- Original focus on transmission operations
   -- New focus on running markets
   -- No longer friendly to transcos
   -- Result for Exelon? Plan to put ComEd transmission into PJM
- -  Rewriting Order No. 888 "Open Access Transmission Tariff" requirements
- -  Codifying interconnection requirements and pricing
- -  Rewriting Standards of Conduct




                                                               [Logo for Exelon]

                   Example: Standard Market Design Initiative

- -  New, controversial FERC initiative for SMD; plan to issue a final rule 12/02
- -  Establishes requirements for energy and transmission markets throughout the
   country
- -  Same trading rules would apply everywhere
- -  Real-time and day-ahead bid-based market for energy using Locational Marginal
   Pricing (LMP) like PJM
- -  LMP-based congestion management
- -  Financial Transmission Rights
- -  Capacity or reserve requirement (maybe!)





                                                               [Logo for Exelon]

                   SMD: Significant $$ and Operational Impact

- -  Exelon "second to none" in supporting SMD
- -  Power Team could save estimated $30 million annually by reducing its
   obligation to provide ancillary services
- -  If SMD includes a capacity or reserve requirement, it could mean Exelon
   Generation would receive significant revenue in capacity payments (depending
   on specifics)
- -  With a spot energy market and an RTO requirement, Exelon would be able to
   serve POLR load in the ComEd area without building/purchasing new capacity if
   the RES load comes back
- -  Reduces our exposure to complaints of market power; provides mitigation
   required to maintain market-based rates
- -  Major plus for "national" players like Exelon

                       Power Team: Who We Are, What We Do

- -  Real transactions that add real value
- -  Dynamic hedging to reduce earnings volatility and add incremental margin
- -  Maximize value of generating assets
- -  Team-oriented incentives focused on cash earnings (vs. volumes or
   mark-to-model)

                             ComEd Supply Vs. Demand

[This slide illustrates the portfolio management challenge faced by Power Team.
The slide shows Power Team's 2001 supply for ComEd from coal, nuclear, oil,
peaking generation, PPAs and spot market purchases stack in thousands of MWs by
month and ComEd demand by day. The need for 100% reliability combined with the
fact that ComEd summer load can vary by over 10,000 MW within a day requires a
pro-active approach to managing Exelon's Midwest portfolio.]

                            ComEd 2002 Summer Supply

- -  Resource planning assumes "high expected load" and requires 23,100 MWs
   -- Based on 20% load demand probability scenario
   -- Exceeds 15% reserve margin as required by MAIN
- -  Exelon Generation has approximately 23,200 MWs available for ComEd needs
   -- 10,000 MWs owned
   -- 13,200 MWs contracted
   -- About 4,000 additional MWs available in region
   -- About 1,000 MWs interruptible

                            ComEd 2002 Summer Supply

- -  What is different from last year?
   -- Earnings guidance assumes substantially lower summer prices
   -- Significantly more supply in region
      - Managing to a 20% probability vs. a 10% probability weather case
   -- EME labor dispute resolved
   -- Full year's experience of managing combined portfolio
   -- Hedging program fully implemented
