The Government of Mauritius has been advocating a shift from conventional fossil fuels to renewable sources for a long time. The first ever power plant built in Mauritius was a small hydro power station at Réduit in 1906. Since then, despite the construction of 7 additional hydropower stations to date, ranging in installed capacities from 900 kW to 29 MW, the share of fossil fuels has been gradually increasing and has now become the major component in the energy mix for electricity generation. Production of electricity on a large scale from biomass (bagasse) started in the late 1950’s when sugar factories came to the conclusion that rather than using bagasse for just producing process steam required for sugar crystallisation, they could first use high pressure steam to generate electricity and the resulting low pressure steam as process heat.With the continued increase in the prices of fossil fuels over the years, the Government decided to turn its attention to renewable energy sources (RES) (bagasse, hydro, solar and wind) with the adoption of the Bagasse Energy Development Plan in the 1990s. The implementation of this plan allowed for a significant increase in the share of bagasse in the generation of electricity. Consistent with this approach of promoting RES, the Government first installed wind turbines for electricity generation in the late 1980s. Unfortunately, those turbines rapidly fell prey to cyclones (hurricanes) and were destroyed. The Government has also renewed its interest in furthering the development of renewable energy and with 22% of its electricity already generated from RES (bagasse and hydro), Mauritius is an international leader in this field. However, most hydro resources have been tapped, while the potential increase in the use of bagasse and its generation efficiency are being pursued.Biomass/biodieselThere is an annual technical potential of producing 1000 GWh of electricity from bagass, cane residues and other biomass by 2013 using current technology. With an ultimate technical annual potential of more than 3000 GWh in 20 years with new varieties of cane and Bagasse Integrated Gasification Combine Cycle turbines. Related ethanol production levels have to be determined according to the different scenarios.HydropowerA technical potential of about 10MW of additional hydropower, particularly through micro-turbines and pico-turbines, is estimated.WindThere is an inland wind power technical potential of between 60 and 140 MW. As well as a total technical potential, including offshore, of 250 MW by 2025, producing 550 GWh annually.SolarAccording to available data from the Mauritius Meteorological Services (MMS), Mauritius, Rodrigues and Agalega enjoy a favourable solar climate with some 2,000 – 2,250 hours of sunshine annually and an average solar radiation of 5.4 kWh/m2/day. This very good solar potential was instrumental in establishing the rationale for the Government to initiate the solar water heater programme in 2008 under the Maurice Ile Durable (MID – The Mauritius Sustainable Island Fund, 2007). Encouraged by the positive response to date with solar water heaters, the next logical step has been for the Government to harness the country’s solar potential for electricity generation from photovoltaics (PV). However, to date, the country has had only limited experience with grid-connected PV electricity generation.
