WISCONSIN GAS LLC

Wisconsin Gas LLC, operating within SIC 4922, stands as a natural gas transmission specialist serving utilities, industrial facilities, and large commercial energy users across Wisconsin and neighboring Midwestern markets. Its core services include high-pressure pipeline transportation, storage balancing, and scheduling support that keep upstream production linked to downstream distribution partners while insulating the grid from seasonal swings. The company also provides ancillary services such as metering, compressor maintenance, and regulatory reporting that reflect the vertically integrated expectations of its customer base. Because it functions within a heavily regulated corridor, Wisconsin Gas continually navigates Federal Energy Regulatory Commission oversight, tariff compliance, and environmental permitting hurdles; any shifts in FERC policy, pipeline safety rulings, or regional demand could materially affect throughput volumes and capital plans. This profile references its most recent Form 10-Q filed in November 1999, underscoring the archival nature of public disclosures and the importance of live filings for current intel (CIK 107819).
