Dane_Co._Overhead_Site_Maps_2026.pdf

This is a Dane County overhead site map document related to the RNG Upgrade Procurement, Construction, and Commissioning contract opportunity in Wisconsin. The project involves replacing Dane County's existing Renewable Natural Gas (RNG) facility located at 7242 Maahic Way, Madison, WI 53718, with qualified firms expected to procure, construct, and commission new equipment. The primary objective is to replace aging nitrogen and carbon removal units (NRU and CRU) with current-generation technology for RNG production from landfill gas sources while increasing processing capacity. An optional pre-proposal site meeting is scheduled for Friday, August 21, 2026, at 2:00 pm at 7102 Maahic Way, Madison, WI 53718, with all questions due by Monday, August 24, 2026. Proposals are due Thursday, September 3, 2026, at 2:00 pm. Work will be performed under a negotiated professional services agreement, and selected firms must demonstrate experience with RNG production systems from landfill gas biogas in cold climates and capacity to manage projects of comparable scope and complexity.

The current Pressure Swing Adsorption (PSA) system, originally commissioned in 2019 and operated by Waste + Renewables staff since 2021, has reached the end of its operational life and requires replacement. Landfill gas volume is projected to exceed current facility capacity in the near future, necessitating system upgrade and expansion. Interested proposers may submit proposals for either complete facility replacement or equipment upgrade options. All work must comply with applicable local ordinances and permitting requirements, and selected firms will coordinate closely with Dane County Waste + Renewable project and operations staff throughout implementation.
