ALSTOM has signed a Euro 23 million turnkey contract to upgrade the power-transmission network on the Caribbean island of Curaçao in the Netherlands Antilles. The contract is with Aqualectra Curaçao N.A., the island's water and electric utility.

Aqualectra needs to upgrade its existing network in order to receive power from the new Build-Own-Operate Isla Power Plant, which is scheduled to begin operation early next year.

The utility is planning to take 25 MW of the plant's 160 MW output, which will allow it to close some of its existing outdated diesel power stations. Thus, it needs to upgrade its existing 30-kV network to 66 kV.

The turnkey project includes all necessary civil works, installation, tests and commissioning, and is expected to be completed within 14 months.

The T&D sector of ALSTOM will build one 66-kV SF₆ gas-insulated switch-gear substation with 11 bays, three 66/30-kV substations comprising several 12-kV and 30-kV gasinsulated bays and 66-kV cable between the 66-kV substation and the 66/30-kV substations. The company also will supply eight power transformers (45 to 75 MVA), associated protection and control equipment and auxiliary equipment.
