3. County Facilities: Onsite Arrays and Online Portals
In 2015, Johnson County was the first county in Iowa to enter into a power purchase agreement (PPA) for solar photovoltaic arrays to power local government buildings. Since then, the County has entered into additional PPAs and made several outright purchases of solar arrays.
