Energy Sector Overview

10/07/2014

Electricity

10/07/2014

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

Biomass

• 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

Biogas

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

Biogas

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

10/07/2014

Likely Benefits

• Bio digesters Construction Cost reduction• Research on Bio-effluent as good fertiliser• Updating the existing biogas models in terms

of gas production.

Geothermal

GEOTHERMAL DEVELOPMENT

10/07/2014

Geothermal

• 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

10/07/2014

Renewable Hydro

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.

10/07/2014

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

pico turbines

10/07/2014

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

10/07/2014

Solar Energy

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

10/07/2014

Solar Energy

PV installations in 300 Schools ( 0.74 kW each)

10/07/2014

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

sector.
