Why is battery energy storage system being introduced in Mauritius?

The CEB is introducing a Battery Energy Storage System (BESS) on its network to arrest the fluctuation inherent to Variable Renewable Energy (VRE) systems. This is due to the increasing share of VRE in Mauritius' energy mix, as the country's energy transition to a low carbon economy gains momentum.

Where are the BESS installations located?

The CEB has two BESS installations located at Amaury Substation and Henrietta Substation. Each BESS is made up of two containers of 20ft housing 10 racks of Lithium Ion batteries for a total energy storage of 1.12 MWh and two power converters with a total installed capacity of 2.24 MW respectively.

How much does a Bess battery cost?

Factoring in these costs from the beginning ensures there are no unexpected expenses when the battery reaches the end of its useful life. To better understand BESS costs, it’s useful to look at the cost per kilowatt-hour (kWh) stored. As of recent data, the average cost of a BESS is approximately $400-$600 per kWh. Here’s a simple breakdown:

What is BESS and how does it work?

BESS (Battery Energy Storage System) is a high-tech, ultra-fast response battery system designed to upgrade the electricity grid. It aims to make the electricity network in Mauritius smarter, more modern, and cleaner.

What is Mauritius' long term energy strategy?

The Government of Mauritius’ Long Term Energy Strategy 2009-2025 aims to increase the share of renewable energy in our energy mix to 35% by 2025. This includes reducing the country’s dependence on coal and heavy oil for electricity generation.

How many BESS installations does the CEB have?

The CEB has two BESS installations of 2 MW power output each. One is installed at Amaury Substation and the other at Henrietta Substation.
