Central Georgia EMC and 38 other electric cooperatives participate in environmentally friendly green power through Green Power EMC. As a member of Green Power EMC, Central Georgia EMC offers electricity generated from biomass; specifically methane gas reclaimed from the Taylor County landfill.
When garbage decomposes in a landfill, a gas is produced. The gas consists of methane, carbon dioxide, oxygen, nitrogen, and non-methane organic compounds. Methane is considered a dangerous greenhouse gas. In a landfill, the harmful methane is destroyed by being burnt in a flare. Landfills are built with wells and underground pipes to draw the gas to the flare.
Landfill power stations tap into the well and underground pipe structure to collect the gas. The collected gas is burnt in a combustion unit, similar to an automobile engine, which drives a generator, producing electricity. The electricity is then run through a transformer to convert to a proper voltage and then exported onto the power grid.
Energy generated through Green Power EMC is transmitted through the power grid and sold to residential, commercial, and industrial customer-owners in 150-kilowatt hour blocks.
Green Power can be purchased for only $4.50 per month. The purchase is automatically added to your electric bill. Green power is available in blocks of 150-kilowatt hours. The cost of green power is slightly higher than that created from usual sources due to the cost of the technologies involved.
