Heritage Gas – Nova Scotia

As 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.

Project Fact Sheet

CES Scope of Work:

  • Comprehensive feasibility study to determine operational viability and cost savings achievable with a system that delivers NG via high pressure tube trailers from a pipeline access point
  • Design engineering of turn-key installation as described below
  • Equipment selection and procurement
  • Project management assistance including all necessary approvals, oversight of equipment installation and commissioning
  • Development of operation and maintenance manuals
  • Operator training
  • Pre-design of future expansion doubling the station’s 2013 throughput capacity
