Enbridge Gas Inc. has applied for approval to construct natural gas pipelines in the City of Markham, Regional Municipality of York, for the purposes of a pilot project involving the distribution of blended natural gas composed of methane with up to 2% hydrogen by volume to approximately 3600 existing customers.
If the application is approved, the project would involve the construction of approximately 755 metres of natural gas pipelines and ancillary facilities in Markham, Ontario. The proposed pipelines are needed to isolate a small portion of Enbridge Gas Inc.’s existing distribution system. When combusted, the blended natural gas will produce lower greenhouse gas emissions relative to traditional natural gas.
The energy density of the blended natural gas is lower than traditional natural gas, meaning that the volumetric consumption of customers in the isolated area will increase. Enbridge Gas Inc. is asking the Ontario Energy Board for approval to refund to affected customers the extra cost associated with consuming the blended gas. Enbridge Gas estimates an annual credit to affected customers of approximately $10 per year.
