Lebanon landfill gas plant running stably; media‑change schedule and reimbursements discussed
Summary
City staff said the landfill gas‑to‑energy plant has run steadily on three microturbines, with one chiller repaired under warranty; testing indicates a siloxane media change will likely be needed in 3–4 months and each exchange costs about $60,000. Staff expect an annual Liberty reimbursement process and estimated approximately $300,000 may be available.
Chris (city staff) reported the landfill gas energy plant has been "running fairly stable" using three microturbines and that a chiller was replaced under warranty.
He said gas testing shows siloxane and other contaminants are increasing in one of the media tanks and that a second media change will likely be required. "If we can get 18 months out of that, that's a significant savings," he said, and estimated a media exchange costs about $60,000.
On finance and metering, staff explained the plant has a Liberty supply meter for its behind‑the‑meter load and a separate revenue‑grade meter that tracks exports. Reimbursements for exported energy are processed annually; Chris said contact Erin Guzman at Liberty estimated Lebanon might receive about $300,000 when the city files for reimbursement.
The committee discussed plating weather protection around a control panel to prevent moisture intrusion, which Chris called a priority given the high‑voltage equipment inside. Staff also noted the plant’s electric load offsets a roughly $3,000 monthly bill to run the plant.
Next steps: staff will watch gas testing trends, schedule the media change when necessary, and proceed with Liberty’s annual reimbursement filing when the letter arrives.
