TRANSMISSION AND DISTRIBUTION
The transmission and distribution system forms the backbone of electricity supply in Mauritius, ensuring reliable power delivery from generation facilities to customers across the island.
How the System Works
- Transmission:
- Electricity is transmitted at higher voltages from generation sources to Bulk Supply Points or Major Substations.
- The transmission system consists of 66 kV lines installed on:
- Steel lattice towers
- Wooden and concrete poles
- Underground cables
- Distribution:
- At substations, the electricity is stepped down to lower voltages to supply the distribution networks.
These networks deliver power directly to homes, businesses, and industries.
Transmission Network Structure
- The 66 kV lines form a ring system and a radial feeder to supply the southern areas of the island.
- The system load is concentrated in:
- The central region, between St. Louis and Wooton
- The northern areas of the island
- The 22 kV outgoing lines from substations serve two main purposes:
- Supplying rural areas
Acting as sub-transmission lines to feed 22/6.6 kV substations
Continuous Investments for Reliability
The CEB continuously invests in upgrading and maintaining the national grid to:
- Strengthen its capacity
- Minimise disruptions
Ensure an efficient and effective network that meets the growing demands of customers
System Control Centre - The Heart of the Grid
The System Control Centre, located in Curepipe, operates 24/7 and serves as the pulse of the CEB’s operations. It is responsible for:
- Monitoring and managing the entire transmission and distribution system
- Ensuring the availability and stability of the power supply across Mauritius
