Wärtsilä has been contracted by Aqualectra, Curaҫao’s government owned utilities company, to provide engineering, procurement and construction (EPC) in support of the country’s decarbonization program. This latest order is for a new 38.4 MW power plant that will be capable of providing efficient grid balancing as the level of renewable energy in the system continues to increase. The order was booked by Wärtsilä in Q3 2024.
The new Salu Power Plant is being supplied on a full EPC basis. Initially, the plant will provide baseload power but will be later utilized in a grid balancing role as part of the utility’s decarbonization focus. It will operate with four Wärtsilä 20V32 engines. According to Wärtsilä, it will immediately become one of Aqualectra’s most fuel-efficient power plants.
Earlier this year, Aqualectra placed an order with Wärtsilä for a battery energy storage system (BESS), as well as Wärtsilä’s GEMS Digital Energy Platform. The combined system will enable the expansion of renewable energy capacity, representing an important step towards a sustainable energy future for the island.
“Aqualectra immensely values the continued partnership with Wärtsilä and their availability to hold discussions, exchange and build bridges so that, on this occasion, we could again sign a significant agreement for the island and people of Curaçao,” said Neysa Isenia, chief financial officer at Aqualectra.
The companies believe that the combination of Wärtsilä’s BESS and GEMS solutions, supported by the new power plant, will provide grid stability and reliability, reduce unserved energy, and help mitigate the risk of brownouts and blackouts. In addition, the Wärtsilä solutions will allow Aqualectra to expand its decarbonisation vision while smoothing the intermittency of renewables.
“We have worked closely with Aqualectra in developing their long-term roadmap,” said Risto Paldanius, vice president, Americas at Wärtsilä Energy. “This involved a detailed analysis and modelling of their system, as well as verifying their own modelling. Aqualectra’s strategic objective is to provide the community with affordable, sustainable, and reliable electricity. Wärtsilä’s solutions will support all of these objectives through reducing the cost of generation, enabling the integration of renewables, while providing high reliability.”
Delivery of the Wärtsilä equipment and construction of the power plant is being carried out on a fast-track basis, and the plant is expected to be fully operational by Q4 2025.
Aqualectra produces and distributes water and electricity to over 80,000 households and companies on Curaҫao Island. The company is an existing and valued Wärtsilä customer with three Wärtsilä engine power plants operating with a combined total of 16 Wärtsilä engines.
