Energy Sector Overview
Source Current/MW % Share
Hydro Domestic 41.95 37.90
Hydro Import 16.5 14.91
Solar 0.25 0.23
Methane gas 4.2 3.79
Thermal 47.8 43.18
• Trainings on Improved charcoal carbonization techniques • Trainings on manufacture
and use of Rural Improved Cookstoves. • Trainings on manufacture
and use of Urban Improved Cookstoves Program
Green•It is renewable •It does not emit soot (CO2) when cooking and it favours cleanliness in the kitchen •Bio-effluent is a good fertiliser
Sustainability•Biogas plant normally lasts for 20 to 30 years •We train masons for construction & maintenance of domestic & institutional biogas- in all Districts •User training is provided to household owning biogas•Provision of after sale services for a period of 1 year
Domestic Biogas• One cow approx. gives 20 kg/ day of dung• Min. size of the Biogas Plant is 4 m3 (2 cows)• Maximum Domestic Biogas Plant has capacity
of 10 m3
Institutional Biogas • Design based on the group size of people or
animals• Minimum size is 10 m3
• The largest is in Ntsinda Prison- 1200 m3
• Bio digesters Construction Cost reduction• Research on Bio-effluent as good fertiliser• Updating the existing biogas models in terms
of gas production.
• The potential for power generation is estimated to be about 700 MW
• Two wells were drilled and as there were no promising outcomes, therefore have to be halted
• A scoping phase has been initiated, with the development of a master plan and completion of missing surface level studies.
Surface Manifestation studies Geology, Geochemistry, Geophysics, Hydrology
Existing Hydropower Electricity• Rwanda presently has about 53% of electricity
supply from hydropower • Approximately a total of around 40 MW are at
advanced construction stages. Likely to increase it contribution to 79% of all electricity supply.
Regional Potential Projects• A total of 512 MW shared with our neighbour
are at different stages of development. Rwanda share will be 1/3.
The Likely Benefits
• Water resource management (Hydrological modelling of river behaviour and sediments analysis)
• Feasibility studies of pico and micro hydro • Model for management of off-grid micro
hydro power plants • Scientific guidance on manufacturing of
Solar PV Energy
• Rwanda is characterised by Savannah climate- solar radiation intensity approx. equal to 5kWh/m2/day and peak sun hours of approximately 5 hours per day.
• Existing projects include a 250 kWp grid connected solar plant (since 2007).
• A two projects 8.5+10 MW are under development in the Eastern Province
Solar Water Heaters (SolaRwanda) Program •The SolaRwanda Program is scheduled for a period of four years (2012-2015). • The objectives & targets of SolaRwanda Program is to promote the widespread use of solar water heaters in residential sector through financial incentives, and other support measures, •Subsidy of 186,000 or 279,000RwF for 200 or 300 L SWH •Goal = 12,000 SWH by the end of the year 2015 with a total estimated yearly saving of 23,328 MWh
PV installations in 300 Schools ( 0.74 kW each)
Other RE Considerations• Off Grid Solutions (Solar, Wind and Hydro)• 52% of access is expected to be from off grid connections
by 2018.• Solar PV off grid connections are considered for
promotion.• A wind assessment study (5 sites) has been undertaken
and suggested there is potential for off-grid wind energy solutions to provide electricity to people in the east of Rwanda. A comprehensive study for wind potential assessment is under consideration.
• 69 Hydro Sites FS is just being concluded and most of them are likely to be developed through off grid systems.
SRDU Areas of Engagement
Our Main focus is in the four areas below (but not limited to that)
o Integration of the energy market,o Renewable forms of energy,o Energy efficiency ando Consequences of climate change on the energy
