While Rwanda is on track to increasing access to electricity, the cost of electricity supply is among the highest in the region. and remains a constraint for the country’s economic and industrial development. The average retail electricity price in Rwanda cost $0.25/kwh. although its caries widely across the nation.
In Rwanda, residential houses with monthly consumption of between 0 -15 kWh, pay RWF 93 ($0.14) per kWh, and those between 15 – 50kWh consumption pay RWF 182 per kWh.
Customers consuming more than 50kW had increased from RWF 189 to RWF 210, while non-residential buildings with monthly consumption of between 0 -100kW, pay RWF 204 per kWh.
Consumers of more than 100kWh per month currently pay RWF 222 per kWh.
For telecom towers, the current price stands at RWF 185 per kWh, while prices for water treatment plants and water pumping stations is RWF 126 per kWh.
Hydroelectric Power Station in Rwanda
Rwanda as a country is in the midst of a rapid expansion of its electrical grid and many new plants are proposed or under construction. Below are some of the hydroelectric operational power stations currently in Rwanda.
- Ntaruka Power Station
- Ntaruka Mukungwa Power Station, River Run of river N/A (11.5 MW), 1959.
- Mukungwa Power Station Mukungwa, Mukungwa River Run of river N/A (12 MW), 1982.
- Mukungwa II Power Station Mukungwa, Mukungwa River Run of riverN/A (2.5 MW), 2010.
- Nyabarongo I Power Station Nyabarongo
- Rukarara Hydroelectric Power Station, Rukarara River.
- Rusizi I Hydroelectric Power Station, Rusizi.
- Rusizi II Hydroelectric Power Station, Rusizi.
In a close survey at Rwanda Electricity instability, it shows the enormous efforts the government is putting to ensure power is made available in the country.
Over the last decade, Rwanda’s hydropower sector showed tremendous progress. The overall installed capacity of power is about 221.1 MW, hydropower contributing 46.8 percent of power generation.
While the publicly-owned power plants are managed by the national utility REG/EUCL. They include larger plants such as Ntaruka, Mukungwa and Nyabarongo I. Independent power producers own and operate 5 plants (10 MW). Other 8 power plants (13 MW) are privately operated through leasing agreements with the Government of Rwanda.
How Rwanda can utilize Solar Energy
Rwanda is one of the countries in Africa that is sufficiently blessed with solar radiation intensity, which is approximately equal to 5kWh/m2/day and peak sun hours of that is approximately 5 hours per day.
In Rwanda, households that is far away from the planned national grid coverage are encouraged to use standalone solar photovoltaic (PVs) to reduce the cost of access to electricity and enjoy the stable flow of electricity.
Current status of renewable energy in Rwanda
As it been mentioned earlier, the primary source of energy in Rwanda as in many other countries of Africa is biomass, Considering energy usage in Rwanda, the main consumers are households (91 percent), followed by the transport sector (4 percent), industry (3 percent), and public services (2 percent).
Most of Electricity in Rwanda comes from renewable sources: as of March 2016, the total currently installed electricity capacity in Rwanda is 160 MW which is a result of the renewable energy generations.
