WILLEMSTAD – While Curaçao residents are facing higher fuel prices this month, electricity bills will remain practically unchanged and water tariffs will rise only slightly, according to the latest pricing update from the Regulatory Authority of Curaçao (RAC).
The explanation reveals how utility pricing on the island works — and why fuel increases do not always immediately translate into higher electricity bills.
According to RAC, water and electricity tariffs consist of two major parts: a fixed base tariff and a variable fuel clause.
The base tariff is calculated once a year and covers operational costs such as staff salaries, maintenance, infrastructure and depreciation.
The variable component changes monthly and depends heavily on production costs.
For electricity, that includes the cost of power purchased from external producers like solar and wind suppliers, as well as fuel used by Aqualectra to generate electricity itself.
For water production, the equation is different.
Water tariffs are influenced by purchased water from third-party suppliers and electricity costs tied to water production.
RAC explained that while fuel costs for electricity production rose slightly, this was offset by a lower correction factor from March, resulting in almost no meaningful change for consumers.
Water, however, saw a different balance.
Although electricity costs for water production decreased, a higher correction factor caused the final tariff to rise.
The regulator says monthly tariff calculations also depend on the “production mix” — the combination of solar, wind, fuel and external supply sources used in a given month.
That mix can significantly influence pricing.
The system allows Curaçao to gradually absorb market fluctuations rather than transferring every international price jump directly to consumers.
For households already struggling with rising food and transport costs, the relatively stable electricity tariff offers some temporary relief.
