Power
Supply
CUC relies upon diesel generation to produce
electricity for Grand Cayman. The island has
neither hydroelectric potential nor inherent
thermal resources, and the Company must rely
upon diesel fuel imported to Grand Cayman
primarily from refineries in the Caribbean and
the Gulf of Mexico. The fuel is transferred by
pipeline from suppliers' tanker terminals to
CUC's centralised generating Power Plant located on
the outskirts of George Town.
Generating Plant
CUC's power system is comprised of 17 generating
units (15 diesel and two gas turbine) with a
combined capacity of 152.6
megaWatts (MW). Generation expansion planning by the
Company is based mainly on historical growth
trends and planned major commercial
developments. In addition, limits prescribed by
CUC's Licence with the Cayman Islands Government
dictate the minimum and maximum reserve
generating capacity that the Company must
maintain to ensure a reliable supply of
electricity after allowance for breakdown and
scheduled maintenance.
Transmission and Distribution (T&D) System
The Company's system is comprised of eight major
transformer substations, approximately 302
miles of overhead high-voltage (69 kiloVolt
and 13 kiloVolt) T&D lines and 14 miles of
high-voltage submarine cable in Grand Cayman.
The T&D lines and substations are designed for
high winds and flooding that might result from a
hurricane. The T&D assets have an original cost
of $190.5 million and a net book value of $145.7
million as of April 30, 2007.
Properties
The Company's generating plant, two of its eight
existing transformer substations, office
building, hurricane centre, warehouse, fuel
tanks and garage are all located on
approximately 28.6 acres of land owned by the
Company and located on North Sound Road, Grand
Cayman. The Company owns five additional sites
for transformer substations located on
approximately 6.4 acres of land. |
