Re:      Sellers of Wholesale Electricity and/or Ancillary Services to the
         California Independent System Operator and/or the California Power
         Exchange During the Years 2000-2001, Docket No. PA02-2-000
         ------------------------------------------------------------------


Dear Mr. Gelinas:

         Exelon Corporation, on behalf of its wholly-owned subsidiaries, PECO
Energy Company and Exelon Generation Company, LLC (collectively, "Exelon"),
pursuant to your May 8, 2002 letter directing all jurisdictional sellers and all
non-jurisdictional sellers to respond to certain enumerated interrogatories and
requests for the production of documents ("May 8 Letter"), hereby submits the
information requested in the May 8 Letter regarding Exelon's business strategies
and practices in the California Independent System Operator ("California ISO")
and California Power Exchange ("California PX") markets during the years 2000
and 2001.

         As indicated in the individual responses furnished herewith, Exelon
engaged in none of the practices associated with the trading strategies
identified with the Enron memoranda that are the focus of the May 8 Letter.
Exelon's responses are based on a thorough search of its records for the
relevant time period.

         Exelon notes that the May 8 Letter is addressed to entities including
Exelon Energy Company, but not Exelon Generation Company, LLC or PECO Energy
Company. However, Exelon Energy Company, a subsidiary of Exelon Corporation,
does not participate and has not participated in the wholesale electricity
markets in California. Exelon assumes that the request was intended to apply to
Exelon Generation Company, LLC and PECO Energy Company, the only members of the
Exelon corporate family that were involved in the wholesale electricity markets
in California during the time period covered by the requests. Thus, Exelon
provides this response on behalf of those entities.

                  Response of Exelon Corporation, on behalf of
             Exelon Generation Company, LLC and PECO Energy Company,
                     to May 8, 2002 FERC Staff Data Request


I.       Requests for Admissions

Request:

A.                1. Admit or Deny: The company engaged in activity referred to
                  in the Enron memoranda as "Export of California Power" during
                  the period 2000-2001, in which the company buys energy at the
                  Cal PX to export outside of California in order to take
                  advantage of the price spread between California markets
                  (which were capped) and uncapped markets outside California.

                  2. If you so admit, provide complete details as to all
                  transactions your company engaged in as part of this activity,
                  including the dates of all purchases and sales of energy
                  and/or ancillary services, counter-parties to the
                  transactions, prices and volumes, delivery points, and
                  corresponding Cal ISO schedules. Also, provide all documents
                  that refer or relate to the activity described immediately
                  above.

Response:

A.                1. Deny. Exelon did not engage in the activity described as
                  "Export of California Power" or any variant of that activity
                  during the relevant time period. Further, Exelon did not
                  schedule exports off the California ISO system during this
                  period.

                  2. Not applicable.

                  Response of Exelon Corporation, on behalf of
             Exelon Generation Company, LLC and PECO Energy Company,
                     to May 8, 2002 FERC Staff Data Request



I.       Requests for Admissions (continued)

Request:

B.                1. Admit or Deny: The company engaged in activity described in
                  the Enron memoranda as "Non-Firm Export" during the period
                  2000-2001, in which the company gets a counterflow (scheduling
                  energy in the opposite direction of a constraint) congestion
                  payment from the Cal ISO by scheduling non-firm energy from a
                  point in California to a control area outside of California,
                  and cutting the non-firm energy after it receives such
                  payment.

                  2. If you so admit, provide complete details as to all
                  transactions that your company engaged in as part of this
                  activity, including the dates of all transactions, congestion
                  payments received, corresponding Cal ISO schedules, counter
                  parties, and delivery points. Also, provide all documents that
                  refer or relate to the activity described immediately above.

Response:

B.                1. Deny. Exelon did not engage in the activity referred to as
                  "Non-Firm Export" or any variant of that activity during the
                  relevant time period. Further, as noted in Exelon's response
                  to Request No. I.A.1., Exelon did not schedule exports off the
                  California ISO system. In addition, Exelon did not participate
                  in the California ISO's congestion market, and therefore
                  Exelon did not receive any congestion payments from the
                  California ISO.

                  2. Not applicable.

                              Docket No. PA02-2-000
                  Response of Exelon Corporation, on behalf of
             Exelon Generation Company, LLC and PECO Energy Company,
                     to May 8, 2002 FERC Staff Data Request


I.       Requests for Admissions (continued)

Request:

C.                1. Admit or Deny: The company engaged in activity described in
                  the Enron memoranda as "Death Star" during the period
                  2000-2001, in which the company schedules energy in the
                  opposite direction of congestion (counterflow), but no energy
                  is actually put onto the grid or taken off of the grid. This
                  allows the company to receive congestion payments from the Cal
                  ISO.

                  2. If you so admit, provide complete details as to all
                  transactions that your company engaged in as part of this
                  activity, including the dates of all transactions, all
                  transmission and energy schedules, the counter parties, all
                  congestion payments received. Also, provide all documents that
                  refer or relate to the activity described immediately above.

Response:

C.                1. Deny. Exelon did not engage in the activity referred to as
                  "Death Star" or any variant of that activity during the
                  relevant time period. Further, as noted in Exelon's Response
                  to Request No. I.B.1., Exelon did not participate in the
                  California ISO's congestion market, and therefore Exelon did
                  not receive any congestion payments from the California ISO.

                  2. Not applicable.

                              Docket No. PA02-2-000
                  Response of Exelon Corporation, on behalf of
             Exelon Generation Company, LLC and PECO Energy Company,
                     to May 8, 2002 FERC Staff Data Request


I.       Requests for Admissions (continued)

Request:

D.                1. Admit or Deny: The company engaged in activity described in
                  the Enron memoranda as "Load Shift" during the period
                  2000-2001. This variant of "relieving congestion" involves
                  submitting artificial schedules in order to receive
                  inter-zonal congestion payments . The appearance of congestion
                  is created by deliberately over-scheduling load in one zone
                  (e.g., NP-15), and under-scheduling load in another,
                  connecting zone (e.g., SP-15); and shifting load from a
                  congested zone to the less congested zone, thereby earning
                  congestion payments for reducing congestion.

                  2. If you so admit, provide complete details as to all
                  transactions that your company engaged in as part of this
                  activity, including the dates of all transactions, all
                  schedules of load by zone, and congestion payments received.
                  Also, provide all documents that refer or relate to the
                  activity described immediately above

Response:

D.                1. Deny. Exelon did not engage in the activity referred to as
                  "Load Shift" or any variant of that activity during the
                  relevant time period. Further, as noted in Exelon's response
                  to Request No. I.B.1., Exelon did not participate in the
                  California ISO's congestion market, and therefore Exelon did
                  not receive any congestion payments from the California ISO.
                  In addition, Exelon has no load in California and did not
                  participate in the balanced scheduling of generation and load
                  in California, nor did Exelon submit artificial schedules to
                  the ISO to create the appearance of congestion.

                  2. Not applicable.

I.       Requests for Admissions (continued)

Request:

E.                1. Admit or Deny: The company engaged in activity described in
                  the Enron memoranda as "Get Shorty" during the period
                  2000-2001, also known as "paper trading" of ancillary services
                  in which it: (i) sells ancillary services in the Day-ahead
                  market; and (ii) the next day, in the real-time market, the
                  company "zeros out" the ancillary services by cancelling the
                  commitment to sell and buying ancillary services in the
                  real-time market to cover its position. The phrase "paper
                  trading" is used because the seller does not actually have the
                  ancillary services to sell.

                  2. If you so admit, provide complete details as to all
                  transactions that your company engaged in as part of this
                  trading strategy, including the dates of all transactions;
                  prices and volumes for sales of ancillary services in the
                  Day-ahead market; the cancellation of such sales, prices and
                  volumes for the purchase of ancillary services in the
                  real-time market to cover the company's position; and
                  corresponding schedules. Also, provide all documents that
                  refer or relate to the activity described immediately above.

Response:

E.                1. Deny. Exelon did not engage in the activity referred to as
                  "Get Shorty" or any variant of that activity during the
                  relevant time period.

                  2. Not applicable.

Request:

F.                1. Admit or Deny: The company engaged in activity described in
                  the Enron memoranda as "Wheel Out" during the period
                  2000-2001. Knowing that an intertie is completely constrained
                  (i.e., its capacity is set at zero), or that a line is out of
                  service, the company schedules a transmission flow over the
                  facility. The company also knows that the schedule will be cut
                  and it will receive a congestion payment without actually
                  having to send energy over the facility.

                  2. If you so admit, provide complete details as to all
                  transactions that your company engaged in as part of this
                  activity, including the dates of all transactions,
                  corresponding schedules, counter parties, and congestion
                  payments received. Also, provide all documents that refer or
                  relate to the activity described immediately above.

Response:

F.                1. Deny. Exelon did not engage in the activity referred to as
                  "Wheel Out" or any variant of that activity during the
                  relevant time period. Further, Exelon did not schedule
                  transmission on the California ISO transmission system and, as
                  noted in Exelon's response to Request No. I.B.1., Exelon did
                  not participate in the California ISO's congestion market, and
                  therefore Exelon did not receive congestion payments from the
                  California ISO.

                  2. Not applicable.

                  Response of Exelon Corporation, on behalf of

                     to May 8, 2002 FERC Staff Data Request


I.       Requests for Admissions (continued)

Request:

G.                1. Admit or Deny: The company engaged in activity described in
                  the Enron memoranda as "Fat Boy" during the period 2000-2001
                  in which the company artificially increases load on the
                  schedule it submits to the Cal ISO with a corresponding amount
                  of generation. The company then dispatches the generation its
                  schedules, which is in excess of its actual load. This results
                  in the Cal ISO paying the company for the excess generation.
                  Scheduling coordinators that serve load in California may be
                  able to use this activity to includes the generation of other
                  sellers.

                  2. If you so admit, provide complete details as to all
                  transactions that your company engaged in as part of this
                  activity, including the dates of all transactions,
                  corresponding schedules, and payments from the Cal ISO for
                  excess generation (including both price and volumes). Also,
                  provide all documents that refer or relate to the activity
                  described immediately above.

Response:

G.                1. Deny. Exelon did not engage in the activity referred to as
                  "Fat Boy" or any variant of that activity during the relevant
                  time period. As noted in Exelon's response to Request No.
                  I.D.1., Exelon did not have any load or generation in
                  California and did not participate in the balanced scheduling
                  of generation and load.

                  2. Not applicable.

                  Response of Exelon Corporation, on behalf of

Request:

H.                1. Admit or Deny: The company engaged in activity described in
                  the Enron memoranda as "Ricochet," also known as "megawatt
                  laundering," during the period 2000-2001, in which the
                  company: (i) buys energy from the Cal PX and exports to
                  another entity, which charges a small fee; and (ii) the first
                  company resells the energy back to the Cal ISO in the
                  real-time market.

                  2. If you so admit, provide complete details as to all
                  transactions that your company engaged in as part of this
                  activity, including the dates for all transactions, names of
                  counter parties and whether they were affiliates, the fees
                  charged, prices and volumes for energy that was bought and
                  then re-sold. Also, provide all documents that refer or relate
                  to the activity described immediately above.

                  "Ricochet" or any variant of that activity during the relevant
                  time period. Further, as noted in Exelon's response to Request
                  No. I.A.1., Exelon did not export power from the California
                  ISO system during the relevant time period.

                  2. Not applicable.

                              Docket No. PA02-2-000
                  Response of Exelon Corporation, on behalf of
             Exelon Generation Company, LLC and PECO Energy Company,
                     to May 8, 2002 FERC Staff Data Request


I.       Requests for Admissions (continued)

Request:

I.                1. Admit or Deny: The company engaged in activity described in
                  the Enron memoranda as "Selling Non-firm Energy as Firm
                  Energy" during the period 2000-2001, in which the company
                  sells or resells what is actually non-firm energy to the Cal
                  PX, but claims that it is "firm" energy. This allows the
                  company to receive payment from the Cal ISO for ancillary
                  services that it claims to be providing, but does not in fact
                  provide.

                  2. If you so admit, provide complete details as to all
                  transactions that your company engaged in as part of this
                  activity, including the dates for all transactions, prices and
                  volumes, and corresponding schedules. Also, provide all
                  documents that refer or relate to the activity described
                  immediately above.

Response:

I.                1. Deny. Exelon did not engage in the activity referred to as
                  "Selling Non-Firm Energy as Firm Energy" or any variant of
                  that activity during the relevant time period. All of Exelon's
                  sales of firm energy in the California markets during the
                  relevant time period represented Exelon's purchase and
                  subsequent resale of firm energy in those markets.

                  2. Not applicable.

                              Docket No. PA02-2-000
                  Response of Exelon Corporation, on behalf of

I.       Requests for Admissions (continued)

Request:

J.                1. Admit or Deny: The company engaged in activity described in
                  the Enron memoranda as "Scheduling Energy to Collect
                  Congestion Charge II" during the period 2000-2001, in which
                  the company: (i) schedules a counterflow even though it does
                  not have any available generation; (ii) in real time, the Cal
                  ISO charges the company for each MW that it was short; and
                  (iii) the company collects a congestion payment associated
                  with the counterflow scheduled. This activity is profitable
                  whenever the congestion payment is greater than the charge
                  associated with the energy that was not delivered.

                  2. If you so admit, provide complete details as to all
                  transactions that your company engaged in as part of this
                  activity, including the dates for all transactions,
                  corresponding schedules, prices and volumes, and congestion
                  payments received. Also, provide all documents that refer or
                  relate to the activity described immediately above.

Response:

J.                1. Deny. Exelon did not engage in the activity referred to as
                  "Scheduling Energy to Collect Congestion Charge II" or any
                  variant of that activity during the relevant time period.
                  Further, as noted in Exelon's response to Request No. I.B.1.,
                  Exelon did not participate in the California ISO's congestion
                  market, and therefore Exelon did not receive any congestion
                  payments from the California ISO.

                  2.       Not applicable.

K.                1. Admit or Deny: The company engaged in any activity during
                  the period 2000-2001 that is a variant of any of the
                  above-described activities or that is a variant of, or uses
                  the activities known as, "inc-ing load" or "relieving
                  congestion," as described above.

                  2. If you so admit, provide a narrative description of each
                  specific time in which the company engaged in such activity
                  and provide complete details of those transactions, including
                  the dates of the transactions, counter parties, prices and
                  volumes bought or sold, corresponding schedules, and any
                  congestion payments received. Also, provide all documents that
                  refer to or relate to such activities.

Response:

K.                1. Deny. Exelon did not engage in the activities referred to
                  as "inc-ing load" and "relieving congestion" or any variant of
                  those activities during the relevant time period. Further, as
                  noted in Exelon's response to Request No. I.B.1., Exelon did
                  not participate in the California ISO's congestion market, and
                  therefore Exelon did not receive any congestion payments from
                  the California ISO and, as noted in Exelon's response to
                  Request No. I.D.1., Exelon has no load in California and did
                  not participate in the balanced scheduling of generation and
                  load in California during the relevant time period.

                  2. Not applicable.

Response:

participant in any ricochet or megawatt laundering transactions and is unaware
of any transactions that it may have conducted with Enron or any of its
affiliates that resulted in a ricochet or megawatt laundering transaction.
