“The collaboration between Optimum Energy and TECO has allowed us to accommodate load growth without adding capital equipment. This is always the first choice, and the efficiency gains provide savings every day of the year. This is a win-win for Optimum Energy, TECO, and TECO’s customers.”

Steve Swinson

CEO, Thermal Energy Corporation

“We had to get the machines that don’t have variable-speed drives to work correctly with those that do, making sure the machines wouldn’t overflow, but we’d still get an efficient flow out of each of them. OptimumLOOP made everything automatic, from slightly adjusting a single valve to improve water flow, to shedding entire machines
from the system when demand decreases. Each of the eight chillers operates at a different output and rate, depending on what gives us the greatest efficiency.”

Kenneth Haltom

“If we turn the system off, we can watch energy usage increase. Then we turn it back on and we can make it go back down again. We can see the immediate, quantifiable impact. The savings are verifiable—we know that our money is being quickly recovered and that the investment is helping patients.”

Kathleen Morlang

Energy Manager, Penn Medicine

“We’re able to get a free cooling effect—with chillers! It’s really kind of crazy. We learned that’s possible by working with Optimum Energy. Otherwise, we never would have known.”

Juan Ontiveros, P.E.

Associate Vice President for Utilities and Energy Management, The University of Texas-Austin

“Being able to reduce energy consumption through optimization is significant. If we don’t have to run the water chillers as hard in the summer months, then we can reduce a good amount of the energy used to condition the outside air… Optimum Energy gave us a lot of the options we were interested in, including making maintenance and operations more flexible and extending the life of the equipment.”

James Johnson

Director of Facilities & Lab Services

“We now have an overall picture of what efficiency across the plant should look like, as well as the savings that we’ve achieved.”

Energy as a Service FAQs

What is an energy-as-a-service company?

An Energy as a Service (EaaS) company provides a model where customers pay for an energy service without having to make the initial capital investment in the energy infrastructure. EaaS providers offer a range of energy solutions, including supply and management, efficiency improvements, and renewable energy sources, under a subscription or contract-based model.

What is the difference between an ESCO and Optimum Energy’s EaaS model?

ESCOs provide energy services to improve efficiency for clients without owning the energy assets, whereas Optimum Energy provides the ability to offload risk by owning, operating, and maintaining specific energy infrastructure under an as-a-service agreement.
