Submarine Cable Distribution

PEA has implemented a development project to extend its services to various islands in the country’s Eastern and Southern regions via a submarine cable connection technology for the 22, 33 and 115 KV. power distribution systems. The project’s construction is carried out in 2 phases:

Construction of the submarine cable connections for the 22 and 33 KV. Power distribution systems, employing 120 and 185 mm2 XLPE (crossed-linked polyethylene) submarine cable. In the 115 kv. Power distribution system, 185 mm2 XLPE (crossed-link polyethylene) and 185 mm2 insulate oil-paper submarine cables are employed.

Construction of the 22 and 33 kv. overland power distribute system to link the submarine to the overland distribution systems and construction of a lows-voltage overland power distribution system via aerial lines.

The principal benefits of this technology are its compliance to the government’s policy of extending PEA’s services to remote rural villages in order to meet the local demand for electricity and the promotion of productivity and economic growth, especially in tourism and relate businesses on these island. The technology also contributes to the improvement of the quality of life of the islanders and the reduction of pollution from diesel electricity generators.

Renewable Energy Electrical Power Generation

PEA has replaced the use of petrol generators and distributes in remote areas with such renewable source of energy such as hydro, solar and wind energy. The use of renewable sources of energy has reduced the level of imported fuel needs, pollution and negative impacts on the environment.

Geographic Information System (GIS)

Geographic Information System (GIS) is a Geographically-referenced information system that projects data in map and table formats. PEA has adopted GIS technology, with reference to the 1 : 4,000 color orthophoto maps for the whole country compiled by the Land Development Development, for the management of all its operations from the planning, Installation, transmission to the maintenance steps of PEA’s electrical power distribution system. GIS technology is essential to the enhancement of PEA’s operation stability and services. It enables PEA’s implementation of many new, fast, accurate and extensive customer services. GIS technology is also used to support other PEA’s operations such as the SCADA, the core business software package, and 1129 PEA Call Center.

Automatic Meter Reading System (AMR)

This system employs the General Packet Radio Service (GPRS) and Global System for Mobile Communications (GSM) technology to collect and store all user’s meter readings data in a central server. AMR system automatically collects data from electric metering devices and transferring them to responsible billing units, thus, eliminating staff’s trips for on-site meter reading. It provides fast and accurate reading of individual user’s energy consumption to be displayed via Web Application. Individual users can monitor their energy consumption on a real-time basis via Internet connection at all time. They can better manage their energy consumption by collecting their load profile and comparing their consumption patterns over a determined period of time. PEA can immediately indentify troubles with user’s meters and utilize user’s load profile data for analyzing and planning of its future electrical power distribution and marketing strategies.
