Case Study: LOTT Cleanwater Alliance achieves energy savings and emissions reductions with Trane Commercial cogeneration

Budd Inlet Treatment Plant: Designing a Cogeneration System

The LOTT Cleanwater Alliance, a wastewater management provider, faced the challenge of wasting energy by flaring methane gas, a byproduct of its treatment process at the Budd Inlet Treatment Plant. This practice was costly, environmentally unfriendly, and caused complaints from the local community. Partnering with Trane Commercial through an Energy Services Performance Contract, LOTT sought a solution for this energy-saving issue.

Trane Commercial designed and installed a high-efficiency cogeneration system and a blower retrofit. The solution eliminated the need to flare gas, reducing annual emissions by over 1,800 metric tons of carbon dioxide. The projects save more than 2.8 million kilowatt-hours of energy per year and are expected to save over $228,000 annually in utility costs for the customer. Trane's work was completed ahead of schedule and funded largely by a conservation grant.
