Plan. Act. Report. (Rinse & Repeat!)


Renewable energy is commonly the least expensive source of energy - lower cost even than buying from the utility. Renewables are also more sustainable and have greater resiliency against outages. Yet decision-makers at businesses and institutions often struggle with renewables, because options are myriad and confusing, and resources are limited.

Sustaine simulates, based on real data, the effect on the utility bill of each energy option – a solar array, battery storage, a lighting retrofit, etc. These simulations enable decision-makers to prioritize and plan effectively, identifying their best option at each step.


With Sustaine, implementing the best energy option is easy. Our network of qualified providers submit competitive bids. Sustaine helps you choose the best bid and execute a favorable contract. We stand beside you through implementation, too, so that savings are turnkeyed and delivered to you.


The optional Sustaine Console provides a variety of reports on savings and sustainability, facilitating transparency for facility owners, operators and occupants.

Rinse & Repeat

Sustaine is with our customers for the long term. Because our software generates a menu of savings opportunities, customers realize savings one option after another.

This is especially true when the menu changes. As renewables prices continue to drop and incentives change, Sustaine's software continuously updates. As the best savings come to light, Sustaine's customers are the first to benefit - again and again.
