Energy Observatory Report 2015 1 " P a g e 1 ENERGY SUPPLY 1.1 Introduction The energy supply of Mauritius is divided into: - Imports of primary energy (Fossil fuels: Heavy Fuel Oil. Liquefied Petroleum Gas, Gasolene, Diesel, Kerosene, Aviation fuel, Coal) - Production of primary energy (Local resources: Bagasse, hydro, wind, landfill gas, fuelwood, photovoltaic) - Primary energy re-exports - Variation of stocks 1.2 Imports The imports of energy sources in 2015 totalled 1775.4 ktoe, as shown in Table 1.1 Fossil Energy Imports 2015 ktonne ktoe Coal 804.2 498.6 Gasolene 154.7 167.1 Diesel oil 318.7 321.9 Aviation fuel 268.8 279.6 kerosene 2.5 2.6 Fuel oil 445.1 427.3 Liquefied Petroleum Gas (LPG) 72.5 78.3 TOTAL 2066.5 1775.4 Data Source: Statistics Mauritius Table 1.1 - Imports of energy sources The distribution of the imports of energy sources are shown in Figure 1.1 Figure 1.1 - Fossil energy imports 2015 Coal 38.9% Gasolene 7.5% Diesel oil 15.4% Aviation fuel 13.0% kerosene 0.1% Fuel oil 21.5% Liquefied Petroleum Gas (LPG) 3.5% Energy Observatory Report 2015 2 " P a g e Petroleum products are intended mostly for the sectors of transport, electricity generation, manufacturing and to a minor level in the household (kerosene), commercial and agriculture sectors, while coal is used primarily for power generation from thermal coal/bagasse power plants with a small fraction being used in the manufacturing sector. Liquefied Petroleum Gas (LPG) is used mainly as cooking and water heating fuel, to a lesser extent as fuel for vehicles. Fig 1.2 shows the trend of fossil fuel import for the period 2005-2015. Data Source: Statistics Mauritius Figure 1.2 - Trend of fossil fuel imports In 2015, imports of fossil fuels increased by 7.6 % compared to 2014. The total import bill of energy sources for 2015 amounted to Rs 23,152.454 M compared to Rs 31, 146.106 M in 2014 representing a decrease of 25.7 %. Petroleum products (Gasolene, Diesel Oil, Dual purpose kerosene, Fuel Oil and LPG) imports amounted to Rs 21,251.223 M, while import value for coal was Rs 1, 900.231 M. 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 304.0 401.6 376.0 347.1 409.6 409.3 452.2 439.2 478.5 498.6 96.0 104.1 117.2 112.8 130.6 126.0 138.4 149.3 148.9 167.1 330.8 310.6 331.7 290.9 313.5 313.0 316.9 339.5 306.7 321.9 245.4 273.1 272.7 212.9 244.2 235.4 221.5 250.7 241.3 279.6 6.3 3.9 6.1 4.3 7.0 4.5 7.3 3.0 2.3 2.6 292.2 320.6 279.4 330.0 327.8 417.4 385.2 411.9 390.2 427.3 63.5 67.8 68.2 67.6 67.7 71.6 73.3 73.7 81.6 78.3 KTOE YEAR Coal Gasolene Diesel oil Aviation fuel kerosene Fuel oil Liquefied Petroleum Gas (LPG) Energy Observatory Report 2015 3 " P a g e 1.3 Primary energy requirement The primary energy requirements are met from imported sources and from local renewable sources as shown in Table 1.2.

In Mauritius, the main sources of renewable energy exploited are biomass, in the form of bagasse, hydro, PV, wind and fuel wood. A total of 251.3 ktoe of local resources was tapped in 2015, as shown in Table 1.3 Local Resources ktonne GWh Ktoe Bagasse 1437.9 230.1 Fuelwood 17.1 6.5 Photovoltaic 25.9 2.2 Landfill gas 20.4 1.8 Hydro 121.9 10.5 Wind 2.7 0.2 Total 1455.0 170.9 251.3 Data Source: Statistics Mauritius Table 1.3 - Primary energy supply in 2015 – Local resources In 2015, primary energy from local resources increased by 18.3 %, compared to 2014. Bagasse is the main source of primary energy from local resources. Photovoltaic (PV), mostly due to the Small Scale Distributed Generation (SSDG) scheme implemented by the CEB which allows Small Independent Power Producers (SIPP) to feed electricity generated through PV plants installed on their premises to the CEB grid, provided 2.2 ktoe of electricity in 2015. Figure 1.4 shows the trend of primary energy obtained from local resources from 2006 to 2015: Data Source: Statistics Mauritius Figure 1.4 - Trend of Primary energy from Local Resources, 2006 – 2015 240.0 230.5 246.4 218.0 225.0 218.1 206.5 201.7 193.4 230.1 8.0 8.0 7.7 7.7 7.7 7.6 7.5 7.3 6.9 6.5 6.6 7.2 9.3 10.5 8.7 4.9 6.4 8.2 7.8 10.5 0.0 50.0 100.0 150.0 200.0 250.0 300.0 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 ktoe Year Bagasse Fuelwood Landfill Gas Photovoltaic Hydro Wind (Rodrigues Island) Energy Observatory Report 2015 5 " P a g e 1.4.1 Hydro electricity Hydroelectricity is the production of electricity from the potential energy of falling water. There were ten plants in operation as at December 2015 across the Island of Mauritius. Data Source: Statistics Mauritius Figure 1.5 - Trend of hydro-electric generation, 2006 to 2015 Hydroelectric power generation accounted for 4.1 % of electricity produced in 2015. Fluctuations in hydroelectric power generation tend to follow annual rainfall levels as shown in Figure 1.5. In 2011, the discrepancy between hydroelectric power generation and rainfall level can be attributed to the water shortage that affected the island of Mauritius where water, that otherwise, would have been used for hydroelectric power generation had to be diverted for use in other sectors. 1.4.2 Bagasse Bagasse is the fibrous residue of sugar cane used by sugar factories for heat production to meet their own requirements. Surplus of bagasse is converted into electricity by thermal power plants found mostly on sugar estates. Figure 1.6 gives the bagasse input for electricity generation and the amount so generated over the period 2006 to 2015. In 2015, 1437.9 ktonnes of bagasse was produced out of which 1240.3 ktonnes was used for electricity generation. 1914 1946 2381 2383 1806 1948 1621 2126 2094 2377 0.0 20.0 40.0 60.0 80.0 100.0 120.0 140.0 0 500 1000 1500 2000 2500 3000 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 mm GWh Hydro power generated (GWh) Mean rainfall whole island (mm) Energy Observatory Report 2015 6 " P a g e Data Source: Statistics Mauritius Figure 1.6 - Trend of electricity generation from bagasse, 2006 to 2015 Table 1.4 shows the ratio of electricity produced per ton of bagasse over the period 2006 to 2015. The ratio varies in the range of 0.41 MWh/tonne to 0.45 MWh/tonne. In 2015, the ratio of electricity produced per tonne of bagasse was 0.411. Also 17.0 % of electricity production was from bagasse representing an increase of 11.7 % compared to 2014. Table 1.4 - Ratio of electricity produced per tonne of bagasse, 2006 - 2015 1.4.3 Photovoltaics (PV) Photovoltaics is a method of generating electrical power by converting solar radiation into direct current electricity using semiconductors. PV installations are generally used as source of electricity in remote areas where access to the CEB network was not accessible or the cost of extension of the existing network is too high. The main applications were in private hunting ground or domains. Another use of PV is for solar powered street lighting. 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 Ratio electricity produced to bagasse input (MWh/tonne) 0.430 0.450 0.374 0.427 0.416 0.435 0.437 0.448 0.443 0.411 1036.6 1040.3 1300.9 1135.6 1140.4 1119.0 1077.8 1056.1 1030.6 1240.3 0.0 100.0 200.0 300.0 400.0 500.0 600.0 0.0 200.0 400.0 600.0 800.0 1000.0 1200.0 1400.0 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 ktonne GWh Electricity (GWh) Bagasse input (ktonne) Energy Observatory Report 2015 7 " P a g e The electricity generation from photovoltaic panels was 25.7 GWh in 2015 compared to 24.5 GWh in 2014. A notable increase arising mainly from the coming into operation of small and medium scale PV plants installed by CEB customers. 1.4.4 Electricity from Wind energy Wind energy comes from the movement of air across the atmosphere of the Earth. Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to generate electricity, windmills for mechanical power, wind pumps for water pumping or sails to propel ships. It may be noted 2.8 GWh of electricity was produced from wind energy in Rodrigues Island in 2015. Two large wind power projects are in the pipeline for Mauritius. This comprises a 29.4 MW plant by Consortium Suzlon-Padgreen Co Ltd and a 9MW plant by Eole Plaines des Roches Ltd for which Power Purchase Agreements were signed in August 2012 and July 2013 respectively. 1.4.5 Electricity from Landfill gas Landfill gas is a gas, constituted of mostly methane, produced by the fermentation of organic waste in landfills in the absence of oxygen. 20.4 GWh of electricity was produced from landfill gas in Mauritius in 2015. 1.4.6 Electricity from biogas Data on biogas from sludge digester used to partially meet the electricity requirements of the St Martin wastewater treatment plant is provided in Table 1.5. 2009 2010 2011 2012 2013 2014 2015 Electricity generated (kWh) 1,093,335 1,140,138 1,185,523 1,145,557 965,616 950,773 644,031 Data source: Wastewater Management Authority Table 1.5 - Electricity produced from biogas at St Martin Treatment plant 1.4.7 Solar Thermal – Solar Water Heaters (SWH) in Mauritius By the end of 2015, it was estimated that there were at least 96, 922 solar water heaters installed, used mainly for the purpose of water heating for bathing in households. This figure has been calculated taking into account the figure of 41 842 SWH provided by the Housing and Population Census 2011 and to the total number of solar water heaters subsidised during the MID Fund schemes 2, 3 and 4 which amounted to 52, 422 SWH. An allowance has been included for SWH beyond economical repairs and those purchased without subsidy. A few additional SWH may have also been installed since 2011 outside the MIDF, without subsidies. It is to be noted that large scale solar water heater are used in other sectors of the economy such as the tourism sector and manufacturing sector to preheat water for swimming pools and boilers. Figures for these sectors are, however, currently not available. Energy Observatory Report 2015 8 " P a g e In the case that these solar water heaters have displaced only electric water heaters, in the ratio of 1 : 5, the avoided electric energy is estimated at 7.9 GWh and the avoided LPG mass is estimated at 10, 736 tonnes. The avoided CO2 emissions, using the grid emission factor for year 2015, and assuming 1.51 kg of CO2 per kilogram of LPG, would be 17, 922.6 tCO2. 1.5 Primary energy requirement The evolution of primary energy consumption over the period 2006 to 2015 is shown in Figure 1.7.

Greenhouse Gases (sometimes abbreviated GHG) have a role comparable to that of glass of a greenhouse shed. The heat from the atmosphere depends on solar radiation (constant) and the amount of radiation trapped by greenhouse gases. 5.2 Greenhouse Gas Emissions A greenhouse gas is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in the Earth's atmosphere are water vapour, carbon dioxide, methane, nitrous oxide, and ozone. Emissions from human activities mainly concern the following six gases, covered by the Kyoto Protocol: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF6). Human activity since the industrial era has led, due to the consumption of fossil energy stocks, to the increase in carbon dioxide in the atmosphere, despite the uptake of a large portion of the emissions through various natural "sinks" involved in the carbon cycle. carbon dioxide (CO2 ) emissions produced by human activities come mainly from combustion of fossil fuels, principally coal, heavy fuel oil and its derivatives (gasolene, diesel, Liquefied Petroleum Gas (LPG) etc.), and natural gas. 5.3 Inventory of CO2 from energy sources for Island of Mauritius in 2015 This report focuses only on CO2 emissions (excluding other greenhouse gases) during combustion of fossil fuels. The scope of emissions discussed concerns all CO2emissions due to fossil energy conversion in all sectors (electricity generation, transport, residential and manufacturing). Figure 5.1 gives the share of carbon dioxide emission from fossil fuel combustion in each sector in 2015. It may be noted that, in 2015, total CO2 emissions from fuel combustion activities amounted to 3,975.6 thousand tonnes and CO2 removals amounted to 295 thousand tonnes. Net CO2 emissions for 2015 was 3,681 thousand tonnes.

It may be observed that the amount of CO2 emitted with respect to GDP has been decreasing since 2010. This shows an increase in the energy efficiency of the local economy. 2006 2007 2008 2009 2010 2011 2012 2013 2014 2015 Net CO2 emissions (ktonnes) 3155.7 3225.7 3187.1 3074.6 3375.0 3351.3 3452.2 3542.9 3675.6 3681.0 tCO2 emissions per capita 2.7 2.8 2.8 2.7 2.9 2.9 3.0 3.0 3.1 3.1 tCO2 per Rs 100,000 GDP (at 2000 prices) 2.19 2.14 2.00 1.83 1.95 1.85 1.83 1.82 1.82 1.76 Data Source: Statistics Mauritius Table 5.1 : CO2 emissions, 2006 -2015 Energy industries (electricity), 2407.5 ktonne, 60.6% Manufacturing industries, 337.8 ktonne, 8.5% Transport, 1032.1 ktonne, 26.0% Residential, 146.9 ktonne, 3.7% Other sectors (Commercial, Agriculture), 51.6 ktonne, 1.3% Energy Observatory Report 2015 30 " P a g e Figure 5.2 : Trend of CO2 emissions, 2012 – 2015 5.5 CO2 emissions for electricity generation In 2015, the total CO2 emissions from electricity generation amounted to 2,407.5 thousand tonnes representing a decrease of 1.7 % compared to 2014.

Bagasse: Cellulosic residue left after sugar is extracted from sugar cane. Capacity: The maximum power available from a power station at a point in time: - Installed capacity: The nameplate capacity of the generator set. - Plant capacity: The net capacity measured at the terminals of the stations, i.e., after deduction of the power absorbed by the auxiliary installations and the losses in the station transformers. - Effective capacity: It is the plant capacity less any amount of derated capacity from the installed capacity. Charcoal: Comprises the solid residue obtained by the destructive distillation of wood in the absence of air. CPP (Continuous Power Producers) Entities which, in addition to their main activities, themselves produce (individually or in combination) electric energy intended, in whole or in part, to meet their own needs from bagasse only and the surplus for sale to the CEB only during the cane harvest period. Coal: Fossil fuel that has a high degree of coalification, with a gross calorific value over24MJ/kg (5700 Kcal/kg) on an ash-free but moist basis. Diesel Oil: Consists primarily of medium oil distilling between 1800 C and 3800 C. Electric energy dependence: The ratio of electricity generation from fossil fuels and electricity generation total. Electric dependency ratio: Ratio between electricity production from fossil fuels and the total electricity production. Energy: Capacity for doing work or for producing heat. Producing heat is a common manifestation of 'doing work' as are producing light and motive force. Energy intensity A measure of the energy efficiency of the economy of the country. Provides a measure of the efficiency with which energy is being used in production. A lower ratio usually reflects a more efficient use of energy. Energy unit: The International System of Units (SI unit) of energy is the Joule. Final energy: Energy Observatory Report 2015 38 " P a g e Energy that is supplied to consumers (electricity, petrol, diesel, natural gas, fuel oil, heating oil). Final Energy Consumption: Energy consumption by final user- i.e. energy which is not being used for transformation into other forms of energy. The consumption by sector is presented as follows: Agriculture: Energy used for irrigation and by other agricultural equipments; Commercial & distributive trade: Energy consumed by the business and commercial sector; Residential: Consumption of energy by residential sector; Manufacturing: Consumption in industry and construction; and Transport: Includes consumption by land vehicles, ships and local aircrafts. Fossils fuels: Formed from the fossilized remains of dead plants and animals by exposure to heat and pressure in the Earth's crust over hundreds of millions of years. Fuels: Term used to describe energy sources that must be subjected to combustion in order to release the energy stored up inside them. Fuel wood: All forms of woody material. Fuel Oils: Heavy oils from the refining process of crude oil and used as fuel in power stations. It is also commonly used by ships and industrial large-scale heating boilers installations as a fuel in furnaces or boilers in the manufacturing sector. Gasoline: A mixture of relatively volatile hydrocarbons, which have been blended to form a fuel suitable for use in spark-ignition internal combustion engines. Gross Domestic Product (GDP): The aggregate money value of all goods and services produced within a country out of economic activity during a specified period, usually a year, before provision for the consumption of fixed capital. Gigawatt hour (GWh): Unit of electrical energy, equal to 3.6 terajoules (TJ). Hybrid vehicle: A vehicle that uses different types of energy for power. This vehicle has usually two types of engines: internal combustion engine and electric motor. IPP (Independent Power Producers): Entities which, in addition to their main activities, themselves produce(individually or in combination) electric energy intended, in whole or in part, to meet their own needs and for sale to the CEB throughout the year from bagasse during the cane harvest period and coal outside this period. Kerosene (excl. Aviation fuel type): A medium oil distilling between 1500 C and 3000 C and which is used in sectors other than aircraft transport. Energy Observatory Report 2015 39 " P a g e Kilowatt (kW): Unit of electrical power equal to 1 000 watts Kilowatt hour (kWh): Unit of electrical energy equal to one kilowatt (1 kW) of power expended for one hour (3 600 s) or 3 600 000 joules. Liquefied petroleum Gas (LPG): Consists mainly of propane or butane, derived from either petroleum refining process or extracted from petroleum streams. It is normally liquefied under pressure for transportation and storage. In Mauritius it is often used to power cooking stoves or gas water heaters and to fuel some types of vehicle. Losses (transmission / distribution losses): Comprise losses in transmission and distribution of electric energy and losses in transformers, which are not considered as integral parts of the power stations. Own use (Station use and loss): Included are consumption by station auxiliaries and losses in transformers, which are considered as integral parts of the power stations. Peak demand: Term used in energy demand management describing a period in which electrical power is expected to be provided for a sustained period at a significantly higher than the average supply level. Peak demand fluctuations may occur on daily, monthly seasonal and yearly cycles. Petroleum products: The primary source of petroleum products is crude oil. Petroleum or crude oil is a naturally occurring, flammable liquid found in rock formations in the Earth. Diesel oil, fuel oils, Gasoline, Kerosene and Liquefied petroleum gas(LPG) are among the major products derived from crude oil distillation. Primary energy: Primary energy designates energy from sources that involve only extraction or capture. Primary energy is not derived from any other forms of energy. By convention, sources of energy that occur naturally such as coal,heavy fuel oil, fuel woodare termed primary energy. Primary energy consumption: The final energy consumption in which is included the losses and consumption of producers and transformers of energy. Production: Comprises gross production, i.e., the amount of electric energy produced, including that consumed by station auxiliaries and any losses in transformers that are considered integral parts of the power station. Renewable energy or Renewables; Natural resources that, after exploitation, can return to their previous stock levels by natural processes of growth or replenishment. Secondary energy: Energy Observatory Report 2015 40 " P a g e Designates energy from all sources of energy that results from transformation of primary sources. e.g. electricity from coal. Solar Thermal Solar energy harnessed in the form of thermal energy Thermal plants: Comprises of conventional thermal plants of all types that require combustion of fuels to generate electricity. They include steam-operated generating plants and plants using internal combustion engines or gas turbines. Thermal sources of electricity: These include coal, oil and its derivatives and bagasse.
