The peat deposits in Rwanda are distributed over an area of 50,000 ha. The studies show that Rwanda has one hundred fifty five (155) million tone of dry peat, which can produce electrical energy, and this deposit is sufficient for Rwanda to achieve energy target. These deposits maybe used for about 30 years. Hereafter, it was felt crucial to do mapping to identify probable locations of peats and find out respective energy potential. The result of the study and assessment of peat to power in Rwanda shows that the average in-situ ash content, in-situ moisture content and in-situ bulk density of the collected peat samples are 36% wt, 70.8% wt and 1112kg/m3 respectively. Their average thickness ranges from 0.9 to 7.8m. In Finland, peat was used as fuel in 1996 and produce 10% of total installed capacity. Rwanda has the same operational power plant in Gishoma; Rusizi District generating 15MW connected to the national electrical grid. A peat-fuelled power plant is under construction and is expected to generate 80 MW. This plant, once completed, is expected to connect 50% more household into national grid before the end of 2018. Thus, this effort along with other projects will increase electrical power from 208 MW to 563 MW in 2024. Peat deposit is expected to generate 500 Mega watt electrical powers during 30 years. Although an effort was done to use peat as fuel, the power plant is still vulnerable to the lack of good quality of dry peat to operate and thus efforts are on to develop suitable technology for exploitation.
