Environment committee likes big biogas-to-energy upgrade at sewage plant

By Jon Willing, Ottawa Citizen, October 15, 2019

A $57.2-million project to upgrade the biogas-to-energy system at the City of Ottawa’s sewage plant received the environment committee’s full endorsement Tuesday.

The city wants to replace aging “cogeneration” engines that convert methane into electricity. There are three engines at the Robert O. Pickard Environmental Centre that produce electricity for part of the plant, but city wants to replace them with more powerful engines and add a fourth one.

Councillors were most concerned about the $41.8 million the city would have to take from the waste water reserve account for the project, leaving $29.4 million in the reserve for other critical work.
