Williams Partners, Southern expand capacity of Transco pipeline in Georgia

EBR Staff Writer Published 02 August 2017

Williams Partners and Southern Company Gas have commissioned the Dalton Expansion Project which aims to increase the supply of natural gas in northwest Georgia.

The project saw the expansion of the existing interstate Transco natural gas transmission pipeline system which delivers natural gas to a power plant jointly operated by Oglethorpe Power, Atlanta Gas Light and the City of Cartersville.

Approved by the Federal Energy Regulatory Commission (FERC) in August last year, the pipeline lateral is jointly owned by Williams Partners and Southern Company Gas.

Through the Dalton Expansion Project, the partners had added a 1858km long steel pipeline spanning from Coweta County to new delivery points in Paulding and Murray Counties in Georgia.

To supply enough gas that would be equivalent to the daily consumption by nearly two million homes, the pipeline was designed to supply about 448,000 dekatherms of natural gas per day.

The Dalton Expansion Project which broke ground in August 2016 has helped the Transco pipeline expand its capacity to 14.2 MMdt/d.

Williams Partners Atlantic-Gulf operating area senior vice president Frank Ferazzi said: “Our Dalton project provides clean-burning natural gas to meet the growing electric generation and local distribution needs in Georgia.

“It is one of several Transco projects creating much-needed access to gas supplies in the northern portion of Transco’s system to meet growing demand in the South.

“In addition to the environmental benefits of connecting electric power generators with this cleaner energy resource, these natural gas pipeline investments produce stable, long-term returns for our business.”

According to Williams Partners, the 10,200mi long Transco pipeline has served Georgia for over 60 years, delivering close to one-third of all of the natural gas used in the state.
