This Technology Transfer Advances Mauritius'
- Nationally Determined Contribution to decrease its greenhouse gas emissions by 30%, by the year 2030, relative to the business as usual scenario of 7 million metric tonnes CO2equivalent.
Context
Approximately 56% of Mauritius’ electricity generation comes from 4 power plants making use of bagasse and coal (40.5 MW to 83 MW) and one power plant operating solely on coal (34.5 MW), using the grate-type stocker boiler technology. Some 683,000 tonnes of coal and 1,000,000 tonnes of bagasse were used for electricity production in 2013. The current utilisation of bagasse enables the country to save on the import of some 375,000 tonnes of coal, thereby preventing the emission of some 1,200,000 tonnes of CO2. However, over the past decade, sugar cane cultivation has significantly decreased and along with it, the amount of bagasse. Likewise, the amount of coal used for electricity production increased by 5% between 2012 and 2013.
Technical Assistance Request
Strengthen Mauritius’ capacities to identify, assess and select the most appropriate technologies, practices and processes for existing coal power plants in order to reduce GHG emissions.
CTCN Response
- Identify, evaluate and assess current boiler technologies, processes and practices at the five power plants operating on coal in the country
- Advise on best environmental practices and best available techniques
- Provide capacity building on the monitoring and evaluation of GHG mitigating measures
- Develop a strategy for proper monitoring of existing coal fired power plants in order to ensure optimum operation and limit GHG emitting potential
Relevant Technologies and Approaches
- Coal combustion with higher efficiency
- Higher efficiency steam boiler
Expected Results
- Identification of emission abatement and monitoring
- Capacity building will inform and guide the work of the government in the energy sector
- Reduction of greenhouse gas emissions at point of generation by minimizing fuel consumption to enhanced energy production efficiency
- Contribution toward meeting Mauritius energy needs while reducing negative environmental impacts from the five existing power plants
