The Microgrid Project

FortisTCI envisions service territories that are less dependent on fossil fuel and operate with a lower carbon footprint. We are making significant energy investments to change the way we deliver the reliable energy you have come to expect.

By leveraging proven technology, FortisTCI will install a utility-scale microgrid on North Caicos and Salt Cay, which will be commissioned in 2024. We are adapting and evolving to meet the needs of the 21st-century electricity system.

Microgrids are localized grids that can disconnect from the traditional grid to operate on their own. This provides redundancy, strengthens the resilience of our grid and supports a faster system response and recovery in the event of a large-scale power outage. A microgrid is defined by three key characteristics: it is local, it is independent, and it is intelligent.

Twin Islands Microgrid in 2024

The twin islands of North Caicos and Middle Caicos are electrically interconnected and are powered by the Providenciales main electricity system via an undersea cable, with diesel standby generators on North Caicos as a back-up source. FortisTCI will install a 1.2 MW solar plus battery microgrid at its property on North Caicos, which will provide 30% of the twin island’s electricity in 2024.

Salt Cay Microgrid in 2024

The island of Salt Cay has a standalone electricity system and due to its size presents an opportunity to integrate a high level of renewable energy. FortisTCI will invest in a 190kW dc microgrid on Salt Cay, which will provide 91% of the island’s electricity supply in 2024.

Quick facts
  • Utility owned solar plus battery energy storage micro-grid
  • 91% renewable energy generation
  • Decrease in overall system cost over time
  • Installation and commissioning in 2024

Our Clean Energy Approach

FortisTCI has embarked on a series of strategic renewable energy investments to meet growing energy demand, accelerate the transition to renewable energy, reduce carbon emissions and lower energy costs over time.

The company’s Clean Energy Plan is based on an integrated resource plan (IRP) study, which has been at the foundation of the Turks and Caicos Islands Resilient National Energy Transition Strategy (R-NETS) for 2019-2040. The criteria used in selecting the optimal generation mix include reliability, least-cost, resiliency, and sustainability. FortisTCI is working to update the IRP to consider changes in technology, environmental conditions, and the findings of technical studies undertaken to determine the feasibility of other alternative energy sources.
