Heritage Gas – Nova Scotia

Heritage gasAs the regional gas utility serving the province of Nova Scotia, Heritage Gas saw a growing opportunity to supply compressed natural gas by bulk transport to large industrial customers and entire communities not currently served by NG pipeline infrastructure. Heritage Gas identified several locations that warranted study and possible implementation of a bulk transport solution.
