Iowa’s largest solar project launched in Dubuque
A 5 MW solar garden – the largest in the state of Iowa – will soon be completed in the Dubuque Industrial Center West. This 21-acre site will also be planted with pollinator-friendly prairie and have 20 beehives maintained by a local beekeeper. A second 1.2 MW garden will revitalize a former foundry site near downtown, as part of a brownfield redevelopment.
Both are expected to begin generating energy in late 2017. In addition to producing clean energy, the facilities will provide valuable insight on how to develop similar sites in collaboration with communities and customers across Iowa. In total, more than 19,000 panels will be installed and will produce enough energy to power over 800 homes.
Integrating sustainable solutions into generation
Our new natural gas facilities in Iowa and Wisconsin are a unique opportunity to apply EnvisionTM as a sustainability rating system and best practice resource. Envision measures the sustainability of an infrastructure project from design through construction and maintenance.
The system is used to meet sustainability goals, help communities and project teams collaborate, prioritize and make decisions about the investment of scarce resources. Envision views a project through a different lens, resulting in actions that may not have been considered. For example, we created public space with interpretive signage via a Native Prairie Nature Trail at our Marshalltown Generating Station property with the use of this system.
Our Marshalltown Generating Station earned a Platinum Envision award, the highest recognition level under the program. Our West Riverside Energy Center is still under construction, but we have set a similar goal for that facility. We are also beginning the Envision certification for our owned wind development sites.
