Williams to supply certified gas to Tennessee utility

Energy infrastructure company Williams said August 3 it had executed an agreement to supply Chattanooga Gas, a subsidiary of Southern Gas Company, with certified, low-emissions natural gas over a three-year period.

The certified gas, which Williams terms “NextGen Gas”, will be sold through its Sequent Energy Management business. Sequent is designed to sell low-carbon and net-zero “NextGen Gas” to utilities, LNG export facilities and other clean energy users.

The delivery of NextGen Gas will allow Chattanooga Gas to achieve a minimum annual emissions reduction savings of approximately 646 tons of methane, or 16,152 tons of carbon dioxide, which is roughly equivalent to removing the emissions from more than 3,500 gasoline-powered automobiles from the road for one year, Williams said.

Williams is deploying its “NextGen Gas” platform across its infrastructure network, leveraging block-chain secured technology to track and measure emissions through the aggregation and reconciliation of multiple sources of data to provide a path-specific methane intensity certification. 

An advanced QMRV (quantification, monitoring, reporting and verification) program deploys technologies including ground-based optical gas imaging cameras, aerial flyovers, satellite monitoring and internal operational systems, which are aggregated and reconciled using a block-chain secured carbon accounting ledger, allowing Williams to provide a certification that meets or exceeds industry leading measurement protocols.
