Turks and Caicos Utilities, a FortisTCI subsidiary, has experienced an extraordinary sequence of incidents involving equipment failure both on the Transmission and Distribution (T&D) system and at the South Base
Plant. The generation failures have all been catastrophic, which is unprecedented in FortisTCI’s history.

has historically delivered to customers.

play,” but are complex hardened infrastructure facilities. We are doing everything possible to address situation and return the service to the level of reliability that our customers deserve and have come to
expect.”

In the meantime, the Company has redeployed several trailer-mounted generation units from to Grand Turk to help stabilize the situation. Mr. Powell added, “We are working as hard as can to return the system to normalcy, but it will take time for the new permanent generation resources be put in place.”

The recent incidences impacting service to customers on Grand Turk are a major focus for the Company the situation there remains unstable. As a result, a team of Electrical and Mechanical Technicians have
been deployed to provide support and to conduct a review to strengthen the overall system. A T&D team is currently performing thermal scanning of the T&D system to locate potential hotspots as a preventative
measure and means of avoiding as many future outages as possible.
