Tennessee Gas Capacity Expansion

On May 23, 2017, Tennessee Gas (Kinder Morgan) posted a new notice of Open Season for bids for further expansion of its existing pipeline system. So far there are no clear system expansion details, maps or specifications, these most likely being dependent on what contracts they obtain from this Open Season. The proposal casts a wide net of possibilities, citing the existing 200 Line in Zones 5 & 6 (New York & New England – running from western to southern to eastern MA), capacity connection to the Maritimes and Northeast pipeline, and the possibility of additional compression and new pipeline.

There are several gas utility projects & issues that we have been monitoring that may possibly have influence over this Open Season call for bids.

Berkshire Gas Moratorium, MA
Berkshire Gas is still imposing a moratorium on any new or expanded gas hook-ups in the Pioneer Valley, citing system constraint and offering only a 19-mile 12″ distribution main as a solution, having not been able to draw from the now cancelled NED project.

Liberty Utilities, NH
Conversion of Keene’s air-propane system to natural gas.

Vernon, VT
Renewed interest in electric generation development on the VT Yankee nuclear plant site, this time calling for a mix of sources including solar, wind, hydro, battery back-up and possible small-scale gas

Pieridae Export Terminal, Goldboro Terminal proposal, Nova Scotia
Renewed call for development of the Goldboro Terminal.
