In order to increase savings through the development of a self-sustaining power supply initiative, telecoms company MTN has installed a two megawatt, methane-driven tri-generation plant, the first of its kind in Africa, at its offices in Fairlands, Johannesburg. The methane gas is piped over 800km from Sasol's Mozambique gas fields to Egoli Gas in Johannesburg, and then to the company's head office.
