Hydropower plants, both large and micro, are the mainstay for production of electrical energy in Burundi. As of 2007, the interconnected network power production comes from 2 national power plants, Rwegura and Mugere, 2 regional power stations - Ruzizi I and II and some smaller power plants. For information on the location of the plants, click here.

Table 3 shows a decrease of 11.3% of electricity production in comparison to 2006‘s production. At the same time, a reduction of imports of this energy is also recorded in the ratios of 8% and 18% respectively for Ruzizi I and Ruzizi II.

On the other hand, the hydropower plants show declined performances of 19% compared to 2005 due to reduced volume of water as well down time for maintenance and cleaning works which have been carried out since April 2006. The poor electricity production at national level as well as at the regional hydropower plants (Ruzizi I and Ruzizi II) has constrained REGIDESO to operate its network by selective power cuts.

The electricity production by the micro plants of DGHER registered a drop of 19% in 2006 compared to 2005 because of a general reduction in  the  level of water and the breakdown of the micro power plant of Kigwena which delivers power to 211 customers.

Challenges in exploiting hydropower resources 

  • Dilapidated state of infrastructure
  • Lack of investment to increase production capacity
  • Reduction in rainfall
