A mandatory RE target is a government legislated requirement
on electricity retailers to source proportions of total electricity
sales from RE sources according to a fixed time frame. Many
countries have targets that may extend for short, medium or long
time. Brazil has 5% power production from RE. India has 4% power
production from various RE sources; 1% from solar energy which
amount to 1.3 GW and 211 GW from all other sources. Egypt has
10% RE production currently, and is expected to be doubled in the
year 2020. Nonetheless, Nigeria has a 0% RE share currently and is
targeting 7% in 2025 [22]. The development of RE technologies in
Nigeria has been slow. New measures are aimed to boost growth
in the energy sector (legislative framework, licensing arrange-
ments for private-sector operators, Feed-in Tariffs and clarifying
market rules for RE service and products). Rural electrification
programs are supposed to take RE sources into full account.
Liberalization of the energy sector, which took place in 2005, has
led to private sector participation in the energy sector, and a
number of operational Independent Power producers (IPPs) are
operating in the country today. Establishment of off-grid genera-
tion/distribution plants is to be encouraged by the government
through the offer of
