In 2010–2011, Anadarko Petroleum and Eni discovered the Mamba South gas field, recoverable reserves of 4,200 billion cubic metres (150 trillion cubic feet) of natural gas in the Rovuma Basin, off the coast of northern Cabo Delgado Province. Once developed, this could make Mozambique one of the largest producers of liquefied natural gas in the world. In January 2017, 3 firms were selected by the Mozambique Government for the Natural Gas Development Projects in the Rovuma gas basin. GL Africa Energy (UK) was awarded one of the tenders. It plans to build and operate a 250 MW gas-powered plant. Production was scheduled to start in 2018.
