Eastern Caribbean’s first power plant with LNG terminal to be constructed in Antigua

Antigua Power Company Limited (APCL) has awarded technology group Wärtsilä a contract to supply and install a 46 MW dual-fuel power plant that will operate primarily on regasified LNG. It is expected to become operational in 3Q2023 and supply electricity to Antigua Public Utilities Authority (APUA) for distribution in the national grid.

The project in Antigua combines both a power plant and an LNG gas terminal, storage and regasification facility, the first of its kind to be installed in the region.  


US-based Eagle LNG, in partnership with APCL, is developing the LNG gas terminal project and APUA will purchase the gas. To supply fuel for the new Wärtsilä power plant, a small-scale LNG storage and regasification terminal will also be installed. The plant itself will operate with five Wärtsilä 34DF dual-fuel engines that can use either gas or light fuel oil.  


The integrated LNG terminal and Wärtsilä power plant concept could become a model for other Caribbean island utilities. The power plant using regasified LNG could result in about 40% less carbon emissions, reports Wärtsilä. The company has already installed power plants in the Eastern Caribbean with a combined capacity of over 3,300 MW.  


‘There is a need to provide additional generating capacity along with the island’s growth in demand for electricity,’ comments Aziz Hadeed, Head of the Hadeed Group of Companies, the parent company of APCL. ‘At the same time, some of the existing power production facilities would soon need to be replaced due to age and the increased focus on more environmentally sustainable systems. Having had good experience with Wärtsilä in the past, we see their dual-fuel power plant solution as the best answer to the island’s green energy plan and its current and future energy requirements.’


Major plant to produce climate-neutral bio-LNG 
In other news, Wärtsilä is also supplying equipment for what is claimed to be the world’s second-largest plant capable of liquefying bio-methane and synthetic methane from renewable sources for the production of carbon-neutral transportation fuel. German energy company Reefuelery, a joint venture of Erdgas Südwest and Avanca, placed the contract in March 2022.


The plant, located in Burghaun near Fulda, Germany, is due to become operational in 1Q2024 and could have a capacity of approximately 57,153 t/y of bio-LNG. It will utilise biomethane from communal and agricultural waste materials as feedstock that will be liquified and delivered to the Alternoil service station network as Reefuel bio-LNG.
