Electricity is 120 volts/60 Hz, the same as in the United States. Supply on Grand Cayman is managed by Caribbean Utilities Co. Ltd. (CUC), which operates under a licence from the Cayman Islands Government.
CUC's power system comprises 18 generating units with a combined capacity of 123 megawatts. The maximum peak load experienced by the company to date was 85 MegaWatts in September of 2004. CUC's projections for power generation growth are based mainly on historical growth trends and planned major commercial developments.
The company’s transmission and distribution system comprises six major transformer substations, 450 miles of overhead high-voltage transmission and distribution lines, and 117 miles of high-voltage submarine cable.
The traditional sources of fresh water supply have been private wells and/or catchment in cisterns, but these have been supplanted by a piped water supply in most areas of Grand Cayman and the western end of Cayman Brac. The public water supply is provided by two companies: the Water Authority and Cayman Water Company. Both provide desalinated water.
The Water Authority is the statutory body responsible for the management of potable water and waste water in the Cayman Islands. The Authority’s piped water in Grand Cayman is distributed from five storage reservoirs: three in George Town, with a total capacity of 3.2 million US gallons; and two in Lower Valley, with a capacity of 3.0 million US gallons.
The Authority’s piped water in Cayman Brac is distributed from two storage reservoirs in West End with a capacity of 750,000 US gallons. In Cayman Brac, water is produced by reverse osmosis; the plant’s production capacity is 150,000 US gallons per day (gpd).
The Authority’s water producer in Grand Cayman is Consolidated Water Co. Ltd., which provides up to 2.9 million gpd of desalinated water from three reverse-osmosis plants - two at the Red Gate Water Works in George Town and a third at the Lower Valley Water Works.
Cayman Water Company supplies more than 2.3 million gpd of piped water to its franchise area and also provides trucked water on Grand Cayman from its facility on West Bay Road.
Cayman's telecommunications system is reliable, competitive, and affordable, and is fast becoming one of the most lucrative sectors since the decentralization and ending of the monopoly by Cable & Wireless. The telecommunications market has been fully privatized.
To accommodate the explosion of the telecommunications industry, the Information and Communications Technology Authority (ICTA) Law was implemented in 2002. The law regulates the entire sector consisting of broadcasting, telephone, internet, and e-business. The Information and Communications Technology Authority (ICTA) is responsible for regulating the local telecommunications agencies. These include Cable & Wireless, Cingular Wireless, Digicel, and TeleCayman. There are now over a dozen providers offering various services such as fixed line, broadband services, mobile services, internet, broadcasting, and internet services.
The latest available statistics from 2003 show that the numbers of fixed and mobile phone lines per person was at least 75% of the population, and 23% of the population possess internet access. The telecommunications of the island is so reliable and state of the art that telecommunications was one of the first utilities to be repaired following Hurricane Ivan in September 2004.
