The tri-generation plant at MTN is unique in that it does not only generates electricity from the methane gas, but also uses a by-product of the process for cooling purposes, since the plant produces an estimated 800kw of cooling for free, resulting in savings in the buildings air conditioning processes. Using the tri-generation plant, methane gas is burned and the energy released by the gas fired engines generates heat and electricity. The waste heat from the engines will be used in the absorption chiller to cool water. More specifically, the 400 celsius exhaust gas is sent through lithium bromide absorption chillers to cool water, which MTN uses for the cooling needs in the building.
