Energy Expert: Turning Down Air Conditioners Could Save 7 MW

In an urgent call to action, Professor Khalil Elahee, Chairman of the MARENA (Mauritius Renewable Energy Agency) and a distinguished energy specialist, said that the Central Electricity Board (CEB) and the Energy Efficiency Management Office (EEMO) have seen a decrease of at least 5 MW during peak hours on Thursdays due to live interventions on the MBC 19:30 news. He emphasizes that energy security starts with controlling demand.
He mentioned that around 30,000 air conditioners are installed each year. For instance, if one out of five air conditioners is running at 8 PM during peak heat, adjusting the temperature from 20°C to 25°C could reduce demand by at least 7 MW. He urges people to stay vigilant throughout the summer and avoid wasteful practices.
The expert also pointed out that refrigerators consume 20% more energy in the summer than in the winter. He believes the Cabinet has approved Minimum Performance Standards for air conditioners, and similar standards should be set for refrigerators.

With climate change expected to raise temperatures by 1.5 to 2°C by 2050, he warns that every 10% increase in humidity without proper ventilation could lead to a 20% rise in energy consumption. He advocates for “solar cooling” solutions for air conditioning and refrigeration.
Additionally, he stresses the need for better demand forecasting. In 2018, the CEB predicted a demand of 265 MW for 2025 but later revised this estimate to 544 MW. The current demand has already reached 567.9 MW. He argues that energy security relies on accurate assessments, and an integrated approach is essential.

He supports the implementation of a Time of Use Tariff, encouraging consumers to pay fair prices for electricity. If consumers produce energy through solar panels, they should be compensated fairly, especially to reduce reliance on heavy fuel oil or kerosene. Engaging the private sector in both managing demand and producing green energy is crucial.
Finally, he calls for practical and holistic solutions, highlighting the need for an integrated action plan. He noted that while desalination is a hot topic, its feasibility must be considered in light of the already high electricity demand. He advocates for decentralized renewable energy solutions over piecemeal responses to the current crises in water and electricity.
