Mayor John Rodriguez switched on Greater Sudbury’s first major renewable energy plant, the Landfill Gas Generation System, located at the Sudbury Landfill on Highway 17 E yesterday.
Once fully operational the $3.2 million plant will supply 1.6 mega watts of electricity, enough to power 1,200 homes and generate approximately $500,000 per year in revenues for the city. Another engine could be added in five years, said officials.
The Greater Sudbury Utilities (GSU) project involves a series of perforated pipes set into the ground where a vacuum slowly draws gases released from decomposing material into the piping where it is cleaned before being sent to a reciprocating engine that then powers a generator. That turn creates electricity for the power grid. Construction of the piping was completed in January 2006.
“Today’s ceremonies reinforces our city’s commitment to alternate energy solutions,” said Rodriguez.
“The landfill gas generation plant at the Sudbury Landfill is an excellent example of how new technologies are converting formerly wasted resources (methane) into lucrative energy sources. So long as we have municipal landfills, we have methane gas to power our homes,” he said in a news release.
Landfill gas is produced when organic waste such as kitchen waste decompose inside a landfill. The gas is roughly 50 percent methane, 50 percent carbon dioxide with other trace gases.
The methane is worrying to climate change experts.
“Methane (CH4) is a greenhouse gas (GHG) 21 times more potent than carbon dioxide and responsible for 16 percent of global GHG emissions. The lions’ share of human induced methane emissions comes from landfills, natural gas and oil systems and coal mining,” states the website Environment Canada.
The Ontario Ministry of the Environment is proposing to make it mandatory for new, expanding and existing operating landfills larger than 1.5 million cubic metres to install systems to capture methane.
Greater Sudbury is the first city in Northern Ontario to install a methane capturing system, said Doug Craig, chair of Greater Sudbury Utilities.
“It took the political will and the expertise that we have on our board, in our utility and in Ontario. When Rodriguez came onto the board of GSU one of his major priorities was getting this plant going,” said Craig.
GSU has a wholly owned subsidiary, GENCO, which investigated the feasibility of capturing methane gas, said Craig. Previously, the Sudbury Landfill burned the methane to prevent its dispersal into the atmosphere.
“I found out two years ago that burning the gas meant a loss of potential revenue to the city of $50,000 a month. I talked to our CEO Doug Reeves and also to Toromont Energy, a Canadian company with expertise in small scale generation plants,” said Craig.
GSU has a 20 year agreement with Toromont to operate and maintain the plant.
“We saw an opportunity to pay back our initial investment of $3.2 million quickly and decided to make it work,” said Craig.
Paula Tarini, supervisor of conservation for GSU, said they have a 20 year agreement with the province for the sale of green energy.
“The new Standard Offer program on Ontario has really helped make it viable. They have established a market-based price of 11 cents per kilowatt hour for green electricity delivered plus a performance incentive of 3.5 cents. We expect production costs to be 3.8 cents so the profit goes directly to the city,” said Tarini.
