Large energy

Optimize your commercial or industrial facilities’ energy ecosystems at the site or enterprise level by seamlessly managing generation, usage and storage. With our energy management software, Concerto™, we can help you design an approach that works for your unique circumstances.

Bring assets online to make money—and save it.

Concerto integrates with your existing assets and control systems to open new revenue streams and savings opportunities without impacting your day-to-day operations. By harnessing the time-based flexibility of electricity-consuming, generation and storage assets, you can reduce demand charges and participate in demand-side management (DSM) programs, including demand response (DR).

Functionality that grows with you

Seamlessly add solar, battery storage, cogeneration or other distributed energy resources from Generac and partner providers, and understand the incremental economic benefit of each asset type before you begin.

An approach as unique as you are.

Concerto can be used for everything from simple asset visibility to a complete notification and DER management platform. Our constraint-based approach allows everyone from wastewater treatment plants to hospitals to participate in DSM. Concerto works behind the scenes 24/7 to leverage previously unseen or unused flexibility.
