Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

(35 ILCS 200/10-515)

Sec. 10-515. Notice requirement.

If the owner of property subject to this Division is a corporation, partnership, limited liability company, trust, or other similar entity, then it shall report to the chief county assessment officer any change in ownership interest or beneficial interest.  If, after October 1, 2007, the ownership interests  or beneficial interests in such an entity change by more than 50% from those interests as they existed on October 1, 2007, then the property no longer qualifies to receive the preferential assessment treatment of the wooded acreage under this Division, and the property must be assessed as otherwise permitted by law beginning the following assessment year.

Division 18.

Wind energy property assessment

(Source: P.A. 95-644, eff. 10-12-07; 95-876, eff. 8-21-08.)

35 ILCS 200/10-600

    (35 ILCS 200/10-600)
    Sec. 10-600. Definitions. For the purposes of this Division 18:

"Wind energy device" means any device, with a
nameplate capacity of at least 0.5 megawatts, that is used in the process of converting kinetic energy from the wind to generate electric power for commercial sale.

"2007 real property cost basis" excludes personal property but represents both the land and real property improvements of a wind energy device and means $360,000 per megawatt of nameplate capacity.

"Trending factor" means a number equal to the consumer price index (U.S. city average all items) published by the Bureau of Labor Statistics for the December immediately preceding the assessment date, divided by the consumer price index (U.S. city average all items) published by the Bureau of Labor Statistics for December 2006.

"Trended real property cost basis" means the 2007 real property cost basis multiplied by the trending factor.

"Allowance for physical depreciation" means (i) the actual age in years of the wind energy device on the assessment date divided by 25 years multiplied by (ii)  the trended real property cost basis. The physical depreciation, however, may not reduce the value of the wind energy device to less than 30% of the trended real property cost basis.

35 ILCS 200/10-605

(35 ILCS 200/10-605)
Sec. 10-605. Valuation of wind energy devices.

Beginning in assessment year 2007, the fair cash value of wind energy devices shall be determined by subtracting the allowance for physical depreciation from the trended real property cost basis.  Functional obsolescence and external obsolescence may further reduce the fair cash value of the wind energy device, to the extent they are proved by the taxpayer by clear and convincing evidence.
