Item 4. Description of Securities.

          Not applicable.

Item 5. Interests of Named Experts and Counsel.

          Not applicable.

Item 6. Indemnification of Directors and Officers.

          WEC is incorporated under the Wisconsin Business Corporation Law (“WBCL”).

          Under Section 180.0851(1) of the WBCL, WEC is required to indemnify a director or officer, to the extent such person is successful on the merits or otherwise in the defense of a proceeding, for all reasonable expenses incurred in the proceeding if such person was a party because he or she was a director or officer of WEC. In all other cases, WEC is required by Section 180.0851(2) to indemnify a director or officer against liability incurred in a proceeding to which such person was a party because he or she was a director or officer of WEC, unless it is determined that he or she breached or failed to perform a duty owed to WEC and the breach or failure to perform constitutes: (i) a willful failure to deal fairly with WEC or its shareholders in connection with a matter in which the director or officer has a material conflict of interest; (ii) a violation of criminal law, unless the director or officer had reasonable cause to believe his or her conduct was lawful or no reasonable cause to believe his or her conduct was unlawful; (iii) a transaction from which the director or officer derived an improper personal profit; or (iv) willful misconduct.

          Section 180.0858(1) provides that, subject to certain limitations, the mandatory indemnification provisions do not preclude any additional right to indemnification or allowance of expenses that a director or officer may have under WEC’s Restated Articles of Incorporation, Bylaws, any written agreement or a resolution of the Board of Directors or shareholders.

          Section 180.0859 of the WBCL provides that it is the public policy of the State of Wisconsin to require or permit indemnification, allowance of expenses and insurance to the extent required or permitted under Sections 180.0850 to 180.0858 of the WBCL, for any liability incurred in connection with a proceeding involving a federal or state statute, rule or regulation regulating the offer, sale or purchase of securities.

II-1

     Section 180.0828 of the WBCL provides that, with certain exceptions, a director is not liable to a corporation, its shareholders, or any person asserting rights on behalf of the corporation or its shareholders, for damages, settlements, fees, fines, penalties or other monetary liabilities arising from a breach of, or failure to perform, any duty resulting solely from his or her status as a director, unless the person asserting liability proves that the breach or failure to perform constitutes any of the four exceptions to mandatory indemnification under Section 180.0851(2) referred to above.

     Under Section 180.0833 of the WBCL, directors of WEC against whom claims are asserted with respect to the declaration of improper dividends or distributions to shareholders or certain other improper acts which they approved are entitled to contribution from other directors who approved such actions and from shareholders who knowingly accepted an improper dividend or distribution, as provided therein.

     Articles V and VI of WEC’s Bylaws provide that WEC will indemnify to the fullest extent permitted by law any person who is or was a party or threatened to be made a party to any legal proceeding by reason of the fact that such person is or was a director or officer of WEC, or is or was serving at the request of WEC as a director or officer of another enterprise, against expenses (including attorney fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such legal proceeding. WEC’s Restated Articles of Incorporation and Bylaws do not limit the indemnification to which directors and officers are entitled under the WBCL.

     Officers and directors of WEC are covered by insurance policies purchased by WEC under which they are insured (subject to exceptions and limitations specified in the policies) against expenses and liabilities arising out of actions, suits or proceedings to which they are parties by reason of being or having been such directors or officers.

     The Plan provides that WEC shall indemnify the Plan administrator, members of the Employee Benefits Committee, members of the Investment Trust Policy Committee, directors and any other employee deemed to be a “fiduciary” against claims in connection with any action or failure to act regarding the Plan (except to the extent any liability may be based on the individual’s own willful misconduct), to the extent required or permitted by law.

Item 7. Exemption from Registration Claimed.

     Not applicable.

     The registrant hereby undertakes that it has submitted or will submit the Plan and any amendment thereto to the Internal Revenue Service (“IRS”) in a timely manner, and has made or will make all changes required by the IRS in order to qualify the Plan under Section 401 of the Internal Revenue Code.

Item 9. Undertakings.

(a)	Rule 415 Offering:
	The undersigned registrant 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 and 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 20% 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) and (a)(1)(ii) do not apply if the registration statement is on Form S-8, and the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference into 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.

(b) Filings Incorporating Subsequent Exchange Act Documents by Reference:

     The undersigned registrant 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 each filing of the Plan’s 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) Undertaking Relating to Filing of Registration Statement on Form S-8:

     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, the 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.

     Re: Wisconsin Energy Corporation Employee Retirement Savings Plan

Ladies and Gentlemen:

     I refer to the Registration Statement on Form S-8 (the “Registration Statement”) being filed by Wisconsin Energy Corporation (the “Company”) with the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “Act”), with respect to the registration of an indeterminate amount of interests in the Wisconsin Energy Corporation Employee Retirement Savings Plan (the “Plan”) and 5,000,000 shares (the “Shares”) of the Company’s Common Stock, $.01 par value (“Common Stock”), for sale to participants in the Plan. Shares of Common Stock for the Plan will be purchased by the Trustee for the Plan in market transactions or may be authorized but unissued or treasury shares acquired directly from the Company.

   I am Counsel for Wisconsin Electric Power Company, the Company’s principal subsidiary. This opinion is being furnished to be filed as an exhibit to the Registration Statement. In furnishing such opinion, I or the attorneys in the Legal Services Department of Wisconsin Electric Power Company have examined (i) the Registration Statement; (ii) the Company’s Restated Articles of Incorporation and Bylaws, as amended to date; (iii) the Plan; (iv) the corporate proceedings relating to the adoption and amendment of the Plan and the authorization for the issuance and/or sale of the Shares thereunder; and (v) such matters of law as I have deemed necessary in order to render this opinion.

   On the basis of the foregoing, I advise you that, in my opinion:

   (1) The Company is a corporation duly incorporated and validly existing under the laws of the State of Wisconsin.

   (2) The Shares sold under the Plan will, when issued (as to any such Shares previously unissued) and paid for in accordance with the provisions of the Plan, be validly issued, fully paid and nonassessable by the Company.

     I am a member of the bar of the State of Wisconsin and I do not hold myself out to be an expert on the laws of any other state. In connection herewith, I express no opinion on the laws of any jurisdiction other than the laws of the State of Wisconsin.

         I consent to the filing of this opinion as an exhibit to the Registration Statement. In giving this consent, I do not admit that I am an “expert” within the meaning of Section 11 of the Act, or that I come within the category of persons whose consent is required by Section 7 of the Act or the rules and regulations of the SEC. This opinion may not be relied upon by you for any other purpose or furnished or quoted to or relied upon by any other person, firm or entity for any purpose, without my prior written consent.

Very truly yours,

/s/ Joshua M. Erickson
