As temperatures are expected to rise in Mauritius, the Central Electricity Board (CEB) is bracing for a significant increase in electricity demand, mainly due to the increased use of air conditioners. According to Khalil Elahee, Chairperson of the Mauritius Renewable Energy Agency, the demand for electricity has already increased by 20-30 megawatts (MW) compared to 2025, not including the impact of air conditioning. This trend is expected to continue, putting pressure on the national grid.
The CEB is taking steps to mitigate the potential strain on the grid, including a renewed awareness campaign to encourage energy conservation, particularly during peak hours between 7 pm and 9 pm. The campaign aims to promote the use of energy-efficient practices, such as setting air conditioners to 25°C, rather than the commonly used 17°C. Simple actions like turning off unnecessary appliances can also make a significant difference, as seen in the 40 MW reduction in demand during critical periods last year.
The simultaneous use of air conditioners during heatwaves can put a strain on the local grid, particularly at the low-voltage transmission level. This can lead to power outages in certain areas, even if the national grid has sufficient capacity. To address this issue, the CEB is exploring ways to upgrade its infrastructure, including the installation of batteries to provide an additional 20 MW of support during peak periods.
Hydroelectric power plants play a crucial role in meeting peak demand, providing clean and affordable energy. However, a decline in rainfall could impact production, prompting the need for alternative solutions. According to Elahee, the CEB is likely to rely on other energy sources, such as gas turbines, to compensate for any shortfall. The agency is also considering long-term solutions, like Pumped Hydro, which involves pumping water to reservoirs during off-peak hours to generate electricity during peak periods.
To mitigate the impact of increased demand, the CEB is promoting the use of renewable energy sources, such as solar power, through initiatives like the Home Solar Scheme. The scheme provides a subsidy of up to Rs 75,000 for households to install solar panels, encouraging them to reduce their reliance on the grid. The commercial and industrial sectors are also being encouraged to adopt energy-efficient practices and invest in renewable energy.
The CEB is taking a holistic approach to managing the increased demand, focusing on demand management, supply, distribution, and machine maintenance. By combining these efforts, the agency aims to avoid power outages and ensure a reliable energy supply during the hot summer months. The public is being urged to play its part in reducing energy consumption, through simple actions like adjusting air conditioner settings and turning off unnecessary appliances.
As the summer months approach, Mauritius is preparing for a challenging period in terms of energy supply. While the CEB is working to upgrade its infrastructure and promote energy conservation, the public is being called upon to take responsibility for reducing its energy consumption. By working together, the country can mitigate the risks of power outages and ensure a reliable energy supply.
Key points
- The CEB is promoting energy conservation measures, such as setting air conditioners to 25°C and turning off unnecessary appliances, to reduce peak demand.
- The agency is exploring alternative energy sources, including solar power and Pumped Hydro, to supplement its energy supply during peak periods.
- The public is being urged to take responsibility for reducing energy consumption, through simple actions like adjusting air conditioner settings and turning off unnecessary appliances.
