IL SB3271

Establishes the Wind Energy Facilities Construction and Deconstruction Act to protect landowners during construction and removal of commercial wind energy facilities of 500 kilowatts or greater capacity.

Requires commercial wind energy operators to enter into agricultural impact mitigation agreements with the Illinois Department of Agriculture prior to construction to preserve the integrity of agricultural land affected by wind facility development.

Mandates wind energy operators complete deconstruction within 18 months after a facility reaches end of useful life (defined as 12+ months of non-operation or 6+ months of unpaid landowner obligations), with deconstruction to begin within 8 months.

Requires operators of new wind facilities to file deconstruction cost plans with the Illinois Commerce Commission and maintain financial assurance through performance bonds, surety bonds, or letters of credit to cover anticipated deconstruction costs; Commission may reevaluate costs every 5 years.

Grants the Illinois Commerce Commission authority to complete deconstruction and access landowner property if operators fail to do so, with existing facility operators required to file deconstruction information within one year of the Act's effective date of January 1, 2013.
