“…Only land with slope between zero and five was kept. Similar values were taken by Ramdé et al (2013) [7]. This criterion is considered in order to mitigate the shadows on PV generators, which alter their performances and reduce their productivities [21] and for avoiding supplementary cost associated with the civil work [7].…”

“…Fluri (2009) [17] and Ramdé et al (2013) [7] consider the proximity of the transmission lines, the land slope, and land cover for the suitable land assessment. Considering the lack in infrastructure of electric energy transport in West Africa, the transmission lines criterion was not considered.…”

“…In favor of its geographical location, solar power appears to be good for increasing access to electricity in West Africa and to improve people's living conditions [7]. There are two 2 Journal of Renewable Energy kinds of solar technologies: the flat-plate PV modules and the concentration PV modules, while, in concentrating solar system, efficiency can reach up to 30% or more [8].…”

“…An investigation of Elhadidy and Shaahid (2000) [16] has shown that PV systems can harness the portion of demand in desert environment of Saudi Arabia. Ramdé et al (2013) [7] use Concentrating Solar Power technologies for assessing the electricity on ECOWAS. The used criteria are as follows: Direct Normal Irradiation (DNI) greater than or equal to 5 kWh⋅m −2 , land slope less than or equal to 5%, and distance to transmission line not more than 100 km.…”

The study presented in this paper analyzes the role that photovoltaic energy can play in enhancing energy self-sufficiency in each of the fifteen Economic Community of West African States (ECOWAS) countries. For this purpose, the satellite CM-SAF database, Global Land Cover data and land slope computed from Digital Elevation Model data, was used to compute the area of suitable lands, the potential of energy, and the coefficient of variation of solar irradiation. The results show that 31.76% of the total area of each ECOWAS country has the potential to shelter photovoltaic energy system generators. Except Cape-Verde which lacks data concerning land cover, all the countries of the community dispose of suitable area for photovoltaic systems installation. Using only 1% of these areas at each country scale the amount of the whole community energy production can reach up to 7782.37 TWh⋅year −1 . The result of solar resource repartition shows that the energy could have a low interannual variation. But, in the same year, a significant variation of solar irradiation exits between months.

“…Solar technologies are more suitable in the Sahelian zone because of a high solar potential of around 5.5 kWh/m 2 [3] and low hydroelectricity as well as wind potential. Wind speeds are indeed low with national averages ranging from 2 to 3 m/s with some peaks of 4 to 5 m/s in some localities [4].…”

Concentrating Solar Power (CSP) is non-existent in Sahel. Such a situation arises from the high investment costs required by these energy infrastructures and from a lack of information on the identification of suitable sites to accommodate them. Conversely, CSP-biomass plants due to lower investment may be an option for CSP penetration in Sahel where Direct Normal Irradiation (DNI) is between 1400 kWh/m 2 /year and 2000 kWh/m 2 /year and significant biomass potential. This work presents the results of an identification of suitable sites for hybrid CSP-Biomass in the Sahel, case study of Senegal, taking into account the Direct Normal Irradiation, the availability of water, space and biomass potential. The identified sites have a DNI > 1600 kWh/m 2 /year. The biogas production capacity is equivalent to 5,096,563 m 3 /year. The quantity of Typha Australis, invasive plant in Senegal river valley available is estimated at more than 3 million tons. The capacity of electrical energy in this zone is estimated at 6.89 GWe for an installation surface estimated at 275.61 km 2 . The establishment of CSP/hybrid plants can also contribute to combat the proliferation of Typha Australis.

Characterizing the variability and meteorological drivers of wind power and solar power generation over Africa

Sub‐Saharan Africa (SSA) has the lowest energy access rates in the world, which poses a key barrier to power system development. Deployment of renewables, including wind and solar power, will play a key role in expanding electricity supply across SSA: distributed generation (enabling access for remote communities), cost‐effectiveness and low emissions are key advantages. However, renewable generation is weather dependent; therefore, including more renewables increases the amount of meteorologically driven variability in the power system. Two countries in SSA are chosen for detailed investigation of this meteorologically driven variability: Senegal in West Africa and Kenya in East Africa. These are chosen due to being areas of dense population, where there is operational wind and solar power, and plans for regional expansion. In Senegal, solar generation is fairly consistent throughout the year, while wind generation exhibits strong seasonality, with a peak in the boreal spring. Low wind and solar power generation days during the boreal summer are found to be related to the passage of African Easterly Waves. Over Kenya, both wind and solar generation exhibit seasonal variability, with wind generation peaking during boreal autumn, and solar generation at a minimum during boreal summer. Inter‐annual variability in generation is greater over Kenya than over Senegal; the El Nino Southern Oscillation is found to impact wind and solar generation over Kenya. El Nino phases are associated with lower wind and solar generation in October–December over Kenya, but higher generation in July–September. This improved understanding of variability will assist system planners in designing reliable future energy systems.
