Nanaimo sewage plant generates 2000 MW annually

TEXT SIZE bigger text smaller text

A wastewater treatment plant in Nanaimo, B.C. is now ready to create electricity from biogas thanks to the installation of a cogeneration system.

The Nanaimo Pollution Control Plant had been using biogas to heat the centre's own buildings and boilers for years. However, those uses only consumed 40% of the gas and the rest had to be flared off into the atmosphere.

The new cogeneration plant can produce 0.33 MW continually, which will mean approximately 2000 MW over a year. With a connection to BC Hydro's grid, it will produce enough power for 325 homes. Associated Engineering was the consulting engineer.

The genesis of the project was a 2003 BC Hydro PowerSmart study which found that cogeneration would be feasible if the project could receive external funding support. The Union of British Columbia Municipalities provided $2.3 million towards the cost of the $2.95-million project.

The Nanaimo facilty is one of the first wastewater treatment plants of its size to install cogeneration.

I think they mean 2000MWh (of energy) not to be confused with the instantaneous output of 0.33MW or 330kW.
