Uplight has successfully managed several notable projects that highlight its capabilities in energy management.

Additionally, Uplight partnered with Consumers Energy and Google to distribute free Google Nest smart thermostats to up to 100,000 households in Michigan, achieving five times higher enrollments compared to traditional programs (source: smartenergycc.org).
