City of Janesville Expands Commitment to Sustainability with New Microturbines
Supported by 90% Project Funding from DOE and ITC, Janesville Leverages Proven Capstone Reliability to Upgrade Energy Infrastructure
LOS ANGELES–(BUSINESS WIRE)–Capstone Green Energy Holdings, Inc. (the “Company” or “Capstone”) (PINK: CGEH) and Capstone Green Energy, LLC., announced that Vergent, Capstone’s distributor for the Upper Midwest, New England, and Eastern Canada, has secured a follow-on order for the City of Janesville, Wisconsin, as they enhance their wastewater treatment facility with new Capstone microturbines. A long-time customer, the City of Janesville has been running Capstone microturbines since 2010 and recently purchased two additional C65 microturbines, one C200S microturbine, and a Vergent controller.
Two C65 microturbines from the original 2010 installation are still in operation. The follow-on project includes the commissioning of a C200 microturbine in November 2024, as well as the recent commissioning of two C65 microturbines in April 2025. These follow-on orders increase the facility’s total on-site generation capacity to 460 kW.
The decision to expand their Capstone microturbine system was driven by Janesville’s positive experience with the reliability and performance of Capstone’s technology. The availability of substantial financial incentives, including the federal Investment Tax Credit (ITC) and a Department of Energy (DOE) ITAC grant, which covered 90% of project costs, helped to further reinforce the City’s commitment to upgrading its energy infrastructure using Capstone solutions.
“Our facility is operating a new microturbine at a fraction of the cost,” said David Botts, P.E., Utility Director for the City of Janesville. “Vergent has been excellent at handling the upgrade for us, with minimal involvement from our team. Having access to so many external funding programs allows us the ability to lower our carbon footprint on a sustainable basis for our community. The process could not have been more seamless. All wastewater treatment facilities should explore similar opportunities to improve their efficiency, all while reducing costs.”
The new microturbines will operate in a combined heat and power (CHP) application, utilizing digester gas as the fuel. The system will supply electricity to support wastewater facility operations. The waste heat from the microturbines is captured and converted into useful thermal energy for the facility’s anaerobic digesters. This efficient and sustainable approach reduces greenhouse gas emissions while significantly lowering operational costs.
“Capstone is honored to continue our collaborative, long-standing relationship with the City of Janesville,” said Vince Canino, President and CEO of Capstone Green Energy. “This project demonstrates the repeatable business model that our Microturbine CHP systems can provide. Our ability to run reliably on digester gas is a great example of recycling a waste stream into a set of useful products that help reduce costs and improve the environment. It is truly exciting to provide enhanced sustainability solutions for municipal facilities like the City of Janesville. This is an excellent model of how wastewater treatment plants can take advantage of their waste streams by leveraging innovative energy solutions that benefit their communities.”
Capstone’s advanced microturbine technology, coupled with Vergent’s expertise in project development and management, allows the City of Janesville to continue its leadership in adopting energy-efficient, clean technology that benefits both the environment and its taxpayers.
