Mathis v. Iowa Utilities Board

In this case concerning an Iowa Utilities Board (IUB) legal standard for when a series of wind turbines constitute an "electric power generating plant or combination of plants at a single site" within the meaning of Iowa Code 476A.1(5), the Supreme Court affirmed the district court's judgment upholding the IUB's declaratory order declining to require a certificate of public convenience, use, and necessity for a large 170-turbine wind project, holding that the IUB did not err in interpreting Iowa Code 476A.1(5).Since 1997, the IUB has ruled that for wind energy purposes all turbines connected to a single gathering line shall be considered a "single site" or "facility" within the meaning of section 476A.1(5) and that turbines connected to separate gathering lines shall be treated as different sites or facilities. Landowners in Palo Alto County in this case argued that the IUB should have exercised jurisdiction over the turbine wind project at issue in this case because, under the common gathering line standard, it did not exceed the minimum power output requirements. The district court upheld the IUB's position declining to require a certificate for the facility. The Supreme Court affirmed, holding that the phrase "single site" is ambiguous and that the IUB's interpretation of section 476A.1(5) is not erroneous. View "Mathis v.
