Loci Controls monitors collection wells remotely, measuring for pressure, temperature and gas composition, among metrics.

Aria Energy, the Michigan-based designers and operators of landfill gas projects, has 110 gas collection wells and, until recently, a plant technician was required to walk around with a handheld device tuning them to optimize production while reducing emissions.
“That took a lot of time. Plus when there’s a problem, you’re more reactive than proactive because you aren’t typically aware of it until later—sometime weeks later, “says Peter Britton, corporate gas processing manager at Aria Energy.
Today, the company leverages a system called Loci Controls that monitors collection wells remotely, measuring for pressure, temperature and gas composition, among metrics. The valve automatically adjusts to help maximize methane gas collection, and the system sends alerts when there are system problems. An online map displays the wells and pinpoints where and what the problem is.
