All references to “the Exelon Trusts” mean Exelon Capital Trust I, Exelon Capital Trust II and Exelon Capital Trust III. All references to “the PECO Trusts” means PECO Energy Capital Trust V and PECO Energy Capital Trust VI.

EXELON GENERATION COMPANY, LLC

Generation was formed in 2000 as a Pennsylvania limited liability company.

Generation has a presence in well-developed wholesale energy markets, uses an integrated hedging strategy that is intended to mitigate the adverse impact of short-term market volatility, and operates a low-cost nuclear generating fleet that has performed consistently at high capacity factors.

At December 31, 2009, Generation owned generation assets with an aggregate net capacity of 24,850 MW, including 17,009 MW of nuclear capacity. Generation controlled another 6,141 MW of capacity through long-term contracts.

EXELON CAPITAL TRUST I, EXELON CAPITAL TRUST II AND

EXELON CAPITAL TRUST III

Each of Exelon Capital Trust I, Exelon Capital Trust II and Exelon Capital Trust III is a Delaware statutory trust that was formed on August 25, 2003. Each of the Exelon Trust’s businesses is defined in a declaration of trust, dated as of August 25, 2003, executed by Exelon, as sponsor, and certain of the trustees specified below. The declaration of trust for an Exelon Trust will be amended and restated in its entirety as of the date trust preferred securities are initially issued by the applicable Exelon Trust. Each declaration, as amended and restated, is referred to in this prospectus individually as the “Exelon Trust Agreement,” and collectively as the “Exelon Trust Agreements.” The Exelon Trust Agreements were qualified under the Trust Indenture Act of 1939, as amended.

The Exelon Trusts exist for the exclusive purposes of:

•

issuing and selling their trust preferred securities and trust common securities;

•

using the proceeds from the sale of the trust common securities and trust preferred securities to acquire the subordinated debt securities from Exelon; and

•

engaging in only those other activities necessary or incidental to these purposes.

The Exelon Trusts will have no assets other than the subordinated debt securities. The Exelon Trusts will have no revenue other than payments under the subordinated debt securities. Each Exelon Trust has a term of 30 years, but may dissolve earlier as provided in the Exelon Trust Agreements.

Exelon will, directly or indirectly, acquire all of the trust common securities of each Exelon Trust, which will have an aggregate liquidation amount equal to at least 3% of the total capital of the issuing trust.

Each Exelon Trust’s business and affairs will be conducted by its trustees, as provided in the Exelon Trust Agreements. At the time of the issuance of the trust preferred securities, the trustees for the issuing Exelon Trust will be U.S. Bank Trust National Association, as the property trustee and the Delaware trustee, and three of our employees as administrative trustees. Exelon, as holder of the trust common securities, or, if an event of default under the applicable trust agreement has occurred and is continuing, the holders of not less than a majority in liquidation amount of the trust preferred securities, will be entitled to appoint, remove or replace the property trustee and the Delaware trustee. In no event will the holders of the trust preferred securities have the right to vote to appoint, remove or replace the administrative trustees. Only the holder of the trust common securities will be entitled to do that.

For so long as the trust preferred securities remain outstanding, Exelon will:

•

maintain directly or indirectly 100% ownership of the trust common securities;

•

use its reasonable efforts to cause the issuing Exelon Trust to remain a statutory trust and not to voluntarily dissolve, wind-up, liquidate or be terminated, except as permitted by the applicable Exelon Trust Agreement; and

•

use its reasonable efforts to cause the issuing Exelon Trust to continue to be treated as a grantor trust and not an association taxable as a corporation for United States federal income tax purposes.

Exelon will pay all of the issuing Exelon Trust’s fees and expenses, including those related to the offering of the trust preferred securities. In addition, Exelon will guarantee payments on the trust preferred securities to the extent that the issuing Exelon Trust has funds to make payments on the trust preferred securities.

The rights of the holders of the trust preferred securities are set forth in the Exelon Trust Agreements and the Delaware Statutory Trust Act.

The location of each Exelon Trust’s principal executive office is 10 South Dearborn Street, 52nd Floor, P.O. Box 805379, Chicago, Illinois 60680-5379, and the telephone number is 312-394-7398.

PECO ENERGY CAPITAL TRUST V AND PECO ENERGY CAPITAL TRUST VI

Each of PECO Energy Capital Trust V and PECO Energy Capital Trust VI is a Delaware statutory trust that was formed on May 9, 2003. Each of the PECO Trust’s businesses is defined in a declaration of trust, dated as of May 9, 2003, executed by PECO, as sponsor, and the trustees specified below. The declaration of trust for a PECO Trust will be amended and restated in its entirety as of the date trust preferred securities are initially issued by the applicable PECO Trust. Each declaration, as amended and restated, is referred to in this prospectus individually as the “PECO Trust Agreement,” and collectively as the “PECO Trust Agreements.” The PECO Trust Agreements were qualified under the Trust Indenture Act of 1939, as amended.

The PECO Trusts exist for the exclusive purposes of:

•

issuing and selling their trust preferred securities and trust common securities;

•

using the proceeds from the sale of the trust common securities and trust preferred securities to acquire the subordinated debt securities from PECO; and

•

engaging in only those other activities necessary or incidental to these purposes.

The PECO Trusts will have no assets other than the subordinated debt securities. The PECO Trusts will have no revenue other than payments under the subordinated debt securities. Each PECO Trust has a term of 30 years, but may dissolve earlier as provided in the PECO Trust Agreements.

PECO will, directly or indirectly, acquire all of the trust common securities of each PECO Trust, which will have an aggregate liquidation amount equal to at least 3% of the total capital of the issuing PECO Trust.

At the time of the issuance of the trust preferred securities, the trustees for the issuing PECO Trust will be U.S. Bank Trust Company National Association, as the property trustee and

the Delaware trustee, and three of our employees as administrative trustees. PECO, as holder of the trust common securities, or, if an event of default under the applicable trust agreement has occurred and is continuing, the holders of not less than a majority in liquidation amount of the trust preferred securities, will be entitled to appoint, remove or replace the property trustee and the Delaware trustee. In no event will the holders of the trust preferred securities have the right to vote to appoint, remove or replace the administrative trustees.

For so long as the trust preferred securities remain outstanding, PECO will:

•

maintain directly or indirectly 100% ownership of the trust common securities;

•

use its reasonable efforts to cause the issuing PECO Trust to remain a statutory trust and not to voluntarily dissolve, wind-up, liquidate or be terminated, except as permitted by the applicable PECO Trust Agreement; and

use its reasonable efforts to cause the issuing PECO Trust to continue to be treated as a grantor trust and not an association taxable as a corporation for United States federal income tax purposes.

PECO will pay all of the issuing PECO Trust’s fees and expenses, including those related to the offering of the trust preferred securities. In addition, PECO will guarantee payments on the trust preferred securities to the extent that the issuing PECO Trust has funds to make payments on the trust preferred securities.

The rights of the holders of the trust preferred securities are set forth in the trust agreements and the Delaware Statutory Trust Act.

The location of each PECO Trust’s principal executive office is 2301 Market Street, P.O. Box 8699, Philadelphia, PA 19101-8699, and the telephone number is 215-841-4000.

USE OF PROCEEDS

Except as otherwise indicated in the applicable prospectus supplement, the registrant expects to use the net proceeds from the sale of the Securities for general corporate purposes, including to discharge or refund (by redemption, by purchase on the open market, by purchase in private transactions, by tender offer or otherwise) outstanding long-term debt. Any proceeds of securities issued by the Exelon Trusts will be used by the Exelon Trusts to purchase subordinated debt securities from Exelon. Any proceeds of Securities issued by the PECO Trusts will be used by the PECO Trusts to purchase subordinated debt securities from PECO. Each registrant will describe in the applicable prospectus supplement any specific allocation of the proceeds to a particular purpose that the registrant has made at the date of that prospectus supplement. Please refer to our annual and quarterly reports incorporated by reference into this prospectus and any prospectus supplement for information concerning each registrant’s outstanding long-term debt.

RATIO OF EARNINGS TO FIXED CHARGES AND RATIO OF EARNINGS TO COMBINED

FIXED CHARGES AND PREFERRED STOCK DIVIDENDS

The following are Exelon’s consolidated ratios of earnings to fixed charges for each of the periods indicated:


	Years Ended December 31,
	2005	2006	2007	2008	2009
Ratio of earnings to fixed charges	2.8	3.4	4.5	4.5	5.4

The following are Generation’s consolidated ratios of earnings to fixed charges for each of the periods indicated:


	Years Ended December 31,
	2005	2006	2007	2008	2009
Ratio of earnings to fixed charges	5.5	6.3	8.2	8.6	10.4

The following are PECO’s consolidated ratios of earnings to fixed charges for each of the periods indicated:

	Years Ended December 31,
	2005	2006	2007	2008	2009
Ratio of earnings to fixed charges	3.8	3.3	3.9	3.1	3.7

The ratio of earnings to fixed charges represents, on a pre-tax basis, the number of times earnings cover fixed charges. Earnings consist of income from continuing operations before income taxes and minority interest plus pre-tax losses of equity method investments and fixed charges, less capitalized interest, the debt portion of allowance for funds used during construction and preference security dividend requirements of consolidated subsidiaries. Fixed charges consist of the sum of interest costs, both expense and capitalized, amortization of debt discount or premium and debt issuance costs, the interest component of rental expense, and preference security dividend requirements of consolidated subsidiaries.

Exelon and Generation had no preferred securities outstanding during the periods indicated; therefore, the ratio of earnings to combined fixed charges and preferred stock dividends is the same as the ratio of earnings to fixed charges for Exelon and Generation.

The following are PECO’s consolidated ratios of earnings to combined fixed charges and preferred stock dividends for each of the periods indicated:

ITEM 15.

INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Exelon Corporation

Chapter 17, Subchapter D of the Pennsylvania Business Corporation Law of 1988, as amended (the PBCL), contains provisions permitting indemnification of officers and directors of a business corporation incorporated in Pennsylvania. Sections 1741 and 1742 of the PBCL provide that a business corporation may indemnify directors and officers against liabilities and expenses he or she may incur in connection with a threatened, pending or completed civil, administrative or investigative proceeding by reason of the fact that he or she is or was a representative of the corporation or was serving at the request of the corporation as a representative of another enterprise, provided that the particular person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. In general, the power to indemnify under these sections does not exist in the case of actions against a director or officer by or in the right of the corporation if the person otherwise entitled to indemnification shall have been adjudged to be liable to the corporation, unless it is judicially determined that, despite the adjudication of liability but in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnification for the expenses the court deems proper. Section 1743 of the PBCL provides that the corporation is required to indemnify directors and officers against expenses they may incur in defending these actions if they are successful on the merits or otherwise in the defense of such actions.

Section 1746 of the PBCL provides that indemnification under the other sections of Subchapter D is not exclusive of other rights that a person seeking indemnification may have under any by-law, agreement, vote of shareholders or disinterested directors or otherwise, whether or not the corporation would have the power to indemnify the person under any other provision of law. However, Section 1746 prohibits indemnification in circumstances where the act or failure to act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness.

II-1

Section 1747 of the PBCL permits a corporation to purchase and maintain insurance on behalf of any person who is or was a director or officer of the corporation, or is or was serving at the request of the corporation as a representative of another enterprise, against any liability asserted against such person and incurred by him or her in that capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify the person against such liability under Subchapter D.

Exelon’s Bylaws provide that it is obligated to indemnify directors and officers and other persons designated by the board of directors against any liability, including any damage, judgment, amount paid in settlement, fine, penalty, cost or expense (including, without limitation, attorneys’ fees and disbursements) including in connection with any proceeding. Exelon’s Bylaws provide that no indemnification shall be made where the act or failure to act giving rise to the claim for indemnification is determined by arbitration or otherwise to have constituted willful misconduct or recklessness or attributable to receipt from Exelon of a personal benefit to which the recipient is not legally entitled.

As permitted by PBCL Section 1713, Exelon’s Bylaws provide that directors generally will not be liable for monetary damages in any action, whether brought by shareholders directly or in the right of Exelon or by third parties, unless they fail in the good faith performance of their duties as fiduciaries (the standard of care established by the PBCL), and such failure constitutes self-dealing, willful misconduct or recklessness.

Exelon has entered into indemnification agreements with each of its directors. Exelon also currently maintains liability insurance for its directors and officers. In addition, the directors, officers and employees of Exelon are insured under policies of insurance, within the limits and subject to the limitations of the policies, against claims made against them for acts in the discharge of their duties, and Exelon is insured to the extent that it is required or permitted by law to indemnify the directors, officers and employees for such loss. The premiums for such insurance are paid by Exelon.

Exelon Generation Company, LLC

Section 4.6 of Generation’s operating agreement provides, as follows:

The Member shall, and any officer, employee or agent of the Company may in the Member’s absolute discretion, be indemnified by the Company to the fullest extent permitted by Section 8945 of the Pennsylvania Limited Liability Company Law of 1994 and as may be otherwise permitted by applicable law.

Section 8945 of the Pennsylvania Limited Liability Company Law of 1994 provides that:

8945. Indemnification.

(a) General rule. Subject to such standards and restrictions, if any, as are set forth in the operating agreement, a limited liability company may and shall have the power to indemnify and hold harmless any member or manager or other person from and against any and all claims and demands whatsoever.

(b) When indemnification is not to be made. Indemnification under subsection (a) shall not be made in any case where the act giving rise to the claim for indemnification is determined by a court to have constituted willful misconduct or recklessness. The certificate of organization or operating agreement may not provide for indemnification in the case of willful misconduct or recklessness.

(c) Grounds. Indemnification under subsection (a) may be granted for any action taken and may be made whether or not the company would have the power to indemnify the person under any other

II-2

provision of law except as provided in this section and whether or not the indemnified liability arises or arose from any threatened, pending or completed action by or in the right of the company. Such indemnification is declared to be consistent with the public policy of this Commonwealth.

(d) Payment of expenses. Expenses incurred by a member, manager or other person in defending any action or proceeding against which indemnification may be made under this section may be paid by the company in advance of the final disposition of such action or proceeding upon receipt of an undertaking by or on behalf of such person to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the company.

(e) Rights to indemnification. The indemnification and advancement of expenses provided by or granted under this section shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to serve in the capacity as to which he was indemnified and shall inure to the benefit of the heirs, executors and administrators of such person.

(f) Mandatory indemnification. Without regard to whether indemnification or advancement of expenses is provided under subsections (a) and (d), a limited liability company shall be subject to section 8331(2) (relating to rules determining rights and duties of partners) and both the members and the managers, if any, shall be deemed to be general partners for purposes of applying that section.

In addition, the officers and employees of Generation are insured under policies of insurance, within the limits and subject to the limitations of the policies, against claims made against them for acts in the discharge of their duties, and the registrant is insured to the extent that it is required or permitted by law to indemnify the officers and employees for such loss. The premiums for such insurance are paid by Generation.

PECO Energy Company

As noted above, the PBCL, contains provisions permitting indemnification of officers and directors of a business corporation incorporated in Pennsylvania. Sections 1741 and 1742 of the PBCL provide that a business corporation may indemnify directors and officers against liabilities and expenses he or she may incur in connection with a threatened, pending or completed civil, administrative or investigative proceeding by reason of the fact that he or she is or was a representative of the corporation or was serving at the request of the corporation as a representative of another enterprise, provided that the particular person acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, the best interests of the corporation, and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful. In general, the power to indemnify under these sections does not exist in the case of actions against a director or officer by or in the right of the corporation if the person otherwise entitled to indemnification shall have been adjudged to be liable to the corporation, unless it is judicially determined that, despite the adjudication of liability but in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnification for the expenses the court deems proper. Section 1743 of the PBCL provides that the corporation is required to indemnify directors and officers against expenses they may incur in defending these actions if they are successful on the merits or otherwise in the defense of such actions.

II-3

PECO’s Bylaws provide that it is obligated to indemnify directors and officers and other persons designated by the board of directors against any liability, including any damage, judgment, amount paid in settlement, fine, penalty, cost or expense (including, without limitation, attorneys’ fees and disbursements) including in connection with any proceeding. PECO’s Bylaws provide that no indemnification shall be made where the act or failure to act giving rise to the claim for indemnification is determined by arbitration or otherwise to have constituted willful misconduct or recklessness or attributable to receipt from PECO of a personal benefit to which the recipient is not legally entitled.

As permitted by PBCL Section 1713, PECO’s Bylaws provide that directors generally will not be liable for monetary damages in any action, whether brought by shareholders directly or in the right of PECO or by third parties, unless they fail in the good faith performance of their duties as fiduciaries (the standard of care established by the PBCL), and such failure constitutes self-dealing, willful misconduct or recklessness.

PECO has entered into indemnification agreements with each of its directors. PECO also currently maintains liability insurance for its directors and officers. In addition, the directors, officers and employees of PECO are insured under policies of insurance, within the limits and subject to the limitations of the policies, against claims made against them for acts in the discharge of their duties, and PECO is insured to the extent that it is required or permitted by law to indemnify the directors, officers and employees for such loss. PECO reimburses Exelon for PECO’s share of the cost of such insurance.

Exelon Capital Trust I, Exelon Capital Trust II, Exelon Capital Trust III, PECO Energy Capital Trust V and PECO Energy Capital Trust VI

Section 3817 of the Delaware Statutory Trust Act, 12 Del. C. Section 3801, et seq., provides that, subject to such standards and restrictions, if any, as set forth in the governing instrument of the trust, a statutory trust shall have the power to indemnify and hold harmless any trustee or beneficial owner or other person from and against any and all claims and demands whatsoever. The trust agreements provide that Exelon, as sponsor of the Exelon Trusts and PECO, as the sponsor of the PECO Trusts, as applicable, will indemnify the trustees for, and hold the trustees harmless against, any and all loss, damage, claims, liability or expense incurred without willful misconduct, gross negligence (ordinary negligence in the case of the Property Trustee) or bad faith on their part, arising out of or in connection with the acceptance or administration of the trust agreements, including the costs and expenses of defending themselves against any claim or liability in connection with the exercise or performance of any of their powers or duties thereunder.

ITEM 17.

UNDERTAKINGS.

(a) Each of the undersigned registrants hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement; provided, however, that paragraphs (a)(1)(i), (a)(1)(ii) and (a)(1)(iii) of this section do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

(A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration

II-5

statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:

Each of the undersigned registrants undertake that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(b) Each of the undersigned registrants hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, each registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
