Energy transition: ER Group’s investment in solar energy

Energy transition is one of ER Group’s climate resilience pillars, under our Sustainability strategy. Across our subsidiaries, we are reshaping the way we produce and consume energy by investing in renewable sources, improving energy efficiency, and advancing the decarbonisation of our operations.
 

This ambition aligns with the Nationally Determined Contribution 3.0, which aims for the phasing-out of coal and a rise in renewable energy to 60% of the national grid supply by 2035. ER Group is part of the solution, acting every day in the field and achieving measurable impact.

ER Group’s contribution to energy resilience
 

Suntricity, EnVolt and Ecoasis, our subsidiaries specialised in renewable energy production, play a central role in delivering photovoltaic (PV) projects across the Group. Suntricity supplies photovoltaic equipment, EnVolt acts as developer, while Ecoasis serves as EPC contractor (engineering, procurement and construction). 

Together, these entities contribute to renewable energy generation, energy efficiency, and improving energy performance across sectors.

PV projects' impact across the Group in 2025

In FY25, ER Group reached 8,407 kWp of photovoltaic capacity installed and 7,173 MWh of solar electricity supplied to the national grid, an equivalent of 14% of our consumption. 
 

• Ascencia: Three rooftop solar farms totalling 3,699 kWp have been installed across Bo’Valon Mall, Riche Terre Mall, and Bagatelle Home & Leisure. 
   
• Decathlon Maurice: The Bagatelle Mall and Beau Plan stores are fully powered by solar panels, generating over 727,000 kWh of renewable energy in 2025.
   
• ER Hospitality: Two 2 MWp photovoltaic farms on Agrïa’s land in Bel Ombre and Case Noyale are in place to meet 80% of Heritage Resorts’ electricity needs.
   
• ER Property: A solar farm was recently launched at Moka City’s Climate Hub, a 2 MW installation generating 3,000 MWh annually and avoiding 2,800 tonnes of CO₂. Solar panels have also been installed on three landmark buildings within Vivéa Business Park: La Piazza, The Pod, and The Factory, generating around 108 MWh of clean electricity annually.
   
• Velogic: A 1.1 MWp photovoltaic plant at the Freeport of Mauritius (‘FoM’) in Port Louis covers 85% of its site electricity needs and reduces its carbon footprint by 1,856 tCO²e (tonnes of carbon dioxide equivalent) annually.
   

Strengthening energy management within operations

Beyond our subsidiaries from our Technology & Energy segment, we are also strengthening energy management within other operations across the Group:

• In 2025, pilot energy audits were carried out at Heritage Le Telfair Golf & Wellness Resort and Heritage Awali Golf & Spa Resort in Bel Ombre, and helped identify opportunities to optimise electricity consumption, improve energy performance and prioritise energy conservation measures. The pilot project highlighted an average potential energy saving of 10%, with a three-year payback period and an estimated 1,000 tonnes of CO₂ avoided.  

Following this pilot project, 20 energy audits across the Group have been conducted and completed in June 2026. These audits covered a portfolio of assets with a combined annual energy bill of approximately Rs 156 million. The assessment identified potential savings of around Rs 15 million, representing an average reduction of 10%. 

• ER Agri has successfully automated two poultry farm buildings, a move that significantly enhances energy efficiency and operational performance. 

• Rogers Capital has implemented a series of energy-saving measures across its offices and data centers. These include the installation of timers to regulate energy usage and the introduction of rigorous monitoring systems for cooling equipment.  

• ER Group is also exploring innovative approaches to strengthen long-term energy resilience. In Bel Ombre, the Group is conducting a feasibility study, co-financed by the Mauritius Research and Innovation Council, on the development of a renewable energy microgrid integrating solar photovoltaic energy, biomass from agroforestry and potentially ocean thermal energy.

Alignment with ER Group’s Sustainability Strategy

We continue to accelerate our transition to cleaner energy in line with our Sustainability Strategy. These initiatives reflect a clear trajectory: deploy renewable capacity, integrate it into operations, and track performance through consistent indicators.
