It's Analyzed & Optimized

Our software analyzes your bill, simulates all your energy options and isolates the best one.

Solution Presented

We show you the best option in clear and simple terms, including how much you can save.

We Deliver

We gather competing bids from qualified providers, help you pick the winner, and deliver your solution. You save! It’s that easy.


Sustaine brings low-cost energy, renewables and energy efficiency to businesses and institutions. Through optimization algorithms, Sustaine recommends best-fit utility, renewables and efficiency options for each client. The Sustaine Marketplace™ then matches priority recommendations with best-in-class solution providers for fulfillment. Once enabled, if necessary, the Sustaine Console™ guides assets to perform optimally on an ongoing basis.


The Sustaine platform recognizes the myriad priorities of most energy decision-makers. Sustaine enables energy decision-makers to quickly and easily determine their single best energy option, then realize its creation through market-based partner selection. Sustaine’s customers participate in meaningful savings opportunities and execute and report sustainability strategies with real data—all without additional staffing or extended timelines. Realize simple, transparent savings--with Sustaine.


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


Renewable energy and efficiency solutions are now commonly the least expensive source of energy--lower cost than simply buying from the grid. They are also more sustainable and have greater resiliency against outages. Yet decision-makers at businesses and institutions, and many energy consultants, struggle around renewables and efficiency. Options are myriad, expertise limited and relationships time-consuming to build.

The Sustaine Marketplace™ provides the ability to simulate, based upon real data, the addition of new sustainable energy assets – a solar array, new cogeneration, battery storage, a lighting retrofit, etc. These simulations provide decision-makers and consultants with the ability to prioritize and plan effectively. Best-fit options can then be matched with best-in-class solution providers for streamlined selection, confident fulfillment and realization of energy and carbon savings.


Once in place, energy assets need to perform as planned in order to deliver savings as envisioned.

The Sustaine Console™ collects gobs of data – interval meter data from your buildings, production data from your energy systems, local and regional real-time grid load and pricing data, weather forecast data (you get the picture) – and uses optimization heuristics to determine when to use or produce more or less electricity on-site, and how much that change will be worth - resulting in substantial energy savings. In simple implementations the Sustaine Console™ runs invisibly in the background, delivering value without degrading comfort or convenience. In sophisticated building environments, a flat-panel screen onsite provides an easy-to-understand daily operating and value schedule, with personalized notifications by text and/or e-mail for all stakeholders.


The Sustaine platform provides a variety of reports, facilitating transparency for energy consultants and facility owners, operators and occupants.

Performance Reporting. Demonstrates visually value accrued due to implemented solutions, including performance against baseline, energy savings and revenue from energy market opportunities.

Sustainability Reporting. Electricity generated by renewables onsite is generally more efficient than the electricity produced by the marginal power plant on the grid. Sustaine measures the carbon intensity of grid power available from the local utility at every hour, and compares that to the carbon intensity of onsite energy production. The result is quarterly and annual carbon savings at each facility. Also, using equivalency calculators provided by the EPA, the carbon emissions avoided are converted into emission equivalents (cars on the road, gallons of gasoline, etc.).
