Jamalco alumina refinery in Jamaica is 55% owned by London-based Noble Group, which acquired it from US-based Alcoa World Alumina LLC in 2014. The remaining 45% is owned by the state through Clarendon Alumina Production Ltd.[8] In 2014, Noble said it planned to construct, by 2017, a coal- or gas-fired power plant for the refinery under a BOOT (build, own, operate, transfer) arrangement.[9]

In 2015, Jamalco said it planned to spend US$500 million on a coal plant to be completed by 2018 fourth-quarter.[10] The plant was to be located in Halse Hall, Clarendon, Jamaica with a 50 MW coal-fired unit.[11][12]

In 2016, in a move welcomed by Jamaican environmentalists[12], Jamalco announced that natural gas would replace coal as the plant's fuel source.[13]

In 2020, project developer New Fortress Energy announced that the Jamalco gas-fired plant had begun commercial operations, supplying up to 100 MW of power to the national grid operated by Jamaica Public Service Company, while providing the alumina refinery with 280,000 pounds of steam per hour in a CHP configuration.[11][14][15][16]

The existing Unit 1 of the plant burns gas and fuel oil,[17] with a 150 MW gas turbine with CHP that began operating in 2020.[18][19][14][11]

In June 2021, New Fortress Energy (NFE) announced the structuring of a sale-and-leaseback deal for the gas plant. Financial services company Sagicor Group Jamaica was engaged to structure the US$285 million deal. Sagicor planned to invest US$100 million and also act as lead arranger on the remaining US$185 million portion which was to come from other investors. The acquisition was subject to regulatory approval.[20] In January 2022, New Fortress Energy announced that it had abandoned plans to sell the plant to Sagicor.[15]

In August 2021, a ruptured oil line caused a fire which injured two persons at the plant and work at the power station slowed as a result.[21] The powerhouse, turbine generator control equipment, two turbines, two control rooms, and a fuel oil pump station were among the assets damaged in the fire which by September 2021 was estimated to be costing the alumina refinery approximately $500,000 daily.[22] Reconstruction was estimated to take until mid 2022.[22]
