An early endorsement has been given by Regional Council to creating a district energy system on the Cogswell Interchange lands slated for redevelopment.
Halifax Water plans to use heat from the nearby sewage treatment plant to create enough thermal energy to heat and cool the six acres of mixed-use developable lands HRM will sell off once the concrete overpass gets town down in the next few years.
The business case for the project, however, relies on mandatory connections for any new structures to be built. Council needs to seek amendments from the province to HRM’s Charter for that power, and staff will need to invent new planning mechanisms to ensure compliance from any developers who buy the new lots off of the city.
Those conditions didn’t sit well with Lower Sackville councillor Steve Craig.
“In concept, the design...I think is admirable,” said the deputy mayor. “Yet the business case that’s attached here says basically we’re going to need a monopoly to make it work.”
A mandatory hookup for district energy systems is “fairly consistent” in other cities, according to HRM’s chief planner Bob Bjerke.
“You need to know that base load is going to be there, to justify the infrastructure cost,” Bjerke told council on Tuesday.

If the system isn’t installed, HRM staff estimate the new Cogswell developments will generate about 262,000 tonnes of greenhouse gas emissions over the next 30 years—equivalent to 55,000 cars driven for a year or 1,400 railcars of coal burned.
