Gas_Sample_Analysis_Spring_2025.pdf

This is a Gas Sample Analysis document for Spring 2025 prepared in support of Dane County's RNG Upgrade Procurement, Construction, and Commissioning contract opportunity in Wisconsin. The document supports Dane County's initiative to replace its aging Renewable Natural Gas (RNG) facility located at 7242 Maahic Way, Madison, WI 53718, which processes landfill gas (LFG) into renewable natural gas. The project requires qualified firms to procure, construct, and commission new nitrogen and carbon removal units (NRU and CRU) to replace the existing Pressure Swing Adsorption (PSA) system that was commissioned in 2019 and has reached the end of its practical life. An optional pre-proposal site meeting was scheduled for Friday, August 21, 2026 at 2:00 pm at 7102 Maahic Way, with all questions due by Monday, August 24, 2026. Proposals were due by Thursday, September 3, 2026 at 2:00 pm. The selected firm will work under a negotiated professional services agreement and must demonstrate experience with RNG production systems from LFG biogas in cold climate environments while managing projects of similar scope and complexity.

The gas sample analysis document serves as a technical reference supporting the facility upgrade evaluation. Firms may propose either complete replacement of the RNG upgrading facility or propose upgrades to existing equipment. The current facility's capacity constraints require expansion to meet projected growth needs. Selected contractors must coordinate closely with Dane County Waste + Renewable (W+R) project and operations staff and comply with all applicable local ordinances and permitting requirements. The document provides essential baseline data for qualified bidders to assess the technical specifications and operational parameters necessary for developing competitive proposals for this infrastructure modernization project.
