Solar energyThe Programme National de Développement des Energies Nouvelles et Renouvelables (ENR), is currently exploring the use of photovoltaic/solar equipment in Djiri. Due to the heavily-forested nature of the country, the potential for power generation by solar photovoltaics is non-ideal, although a significant potential for solar thermal utilisation exists. Average insolation in the country ranges from 2.0-3.0 kWh/m2/day.Wind energyCurrent development of wind energy technologies is minimal and current installed capacity is at a similar level, although sites have been identified in both the North and South of the country as having sufficient potentials to generate electricity. Average wind speeds of ~5.5-6.0 m/s have been observed. Biomass energyThere is currently a great deal of forestry for wood, which is used to produce energy. Significant biomass energy potential exists in the country, particularly in the form of the production of palm oil for biodiesel. Some 12 million acres of land have been identified as having the potential to support some form of woody biomass for energy use. The African Fund for Biofuels and Renewable Energy is currently supporting the Congo-Carbon project, which will be implemented in two phases: the production of industrial carbon from forest residues, and reforestation in areas of depleted forest resources. Geothermal energyCurrently, no geothermal resources have been identified in the country, and no major studies into the potential resource have been conducted. Hydropower An exhaustive inventory carried out in 1981 identified a number of sites which can accommodate large hydroelectric power stations, and the hydroelectric potential of this (2,500MW) would certainly be a good substitute for wood energy. Two of these sites are around Pointe Noire and Brazzaville, which contain the majority of the Congolese population. The most significant project would be the Sounda Gorge dam, with an estimated capacity of 1,200 MW. Ministerial consultations have been held with South Africa’s Industrial Development Corporation to consider financing for the US$ 1 billion project. Recent developments have included the Imboulou hydroelectric project, expected to have expanded to 120 MW of capacity by the end of 2011.
