JAMAICA'S ELECTRICITY GENERATION STATIONS
A power station (also referred to as a generating station, power plant, or powerhouse) is an industrial facility for the generation of electric power. JPS owns a number of fossil fuel plants that use Heavy Diesel Oil (HDO) and Automotive Diesel Oil (ADO), as well as eight hydro plants. We are also in the process of constructing our first wind farm. More information is available here.
JAMAICA'S ELECTRICITY LOAD CENTRES
A Load centre is a combination of meter centre and breaker/set of breakers, Kingston and Montego Bay are the 2 load centres of the JPS grid.
JAMAICA'S ELECTRICITY 138 KV TRANSMISSION LINES
138 kv - High voltage lines carrying 138 kilovolts or 138,000 volts, this is the backbone of the Transmission System,carrying power from the plants to substations around the island.
69 KV TRANSMISSION LINES
69 kv - High voltage lines carrying 69 kilovolts or 69,000 volts, for the exclusive license to distribute and sells electricity in jamaica, the voltage at the Interconnection Point is now maintained at 69 kV, +/- 5%.
24 KV TRANSMISSION LINES
24 kv - Medium voltage lines carrying 24 kilovolts or 24,000 volts, Within the past five (5) years, seventeen (17) feeders were upgraded from 13.8 kV to 24 kV, simultaneously increasing feeder capacity while reducing technical losses by 0.80%. This Line also forms apart of the distribution network, which takes the power from substations, to customers, via transformers.
12 KV TRANSMISSION LINES
12 kv - Medium voltage lines carrying 12 kilovolts or 12,000 volts, This forms apart of the distribution network, which takes the power from substations, to customers, via transformers.
13.8 KV TRANSMISSION LINES
13.8 kv - Medium voltage lines carrying 13.8 kilovolts or 13,800 volts for the exclusive license to distribute and sell selctrcity in jamaica, 7,968 miles – distribution - 13.8kV, This line also forms apart of the distribution network, which takes the power from substations, to customers, via transformers.
ALL ISLAND ELECTRICITY GRID
The sense of grid is as a network, and should not be taken to imply a particular physical layout, or breadth. "Grid" may be used to refer to an entire continent's electrical network, a regional transmission network or may be used to describe a subnetwork such as a local utility's transmission grid or distribution grid. Electricity in a remote location might be provided by a simple distribution grid linking a central generator to homes.
