Introduction

l
l
Electricity is a required input for economic growth and an
indicator of the level of development of a country
A successful economy depends on secure, safe and efficient
supply and use of electricity
Access to electricity in the rural area will reduce the rural –
urban drift and enhance development of rural economy
Nigeria has enormous solar energy potential as shown in the
map below.
However it is not currently exploited in significant capacity

Barriers
l
l
Grid supplies are usually the cheapest option in areas
with high load densities, as well as in areas near the
grid.
However, a number of challenges militates against gridconnected solar-energy- sources Electricity supply
 High
costs of installation and wiring provided by utilities are high,
 Large land area required
 Not dispatchable (can not respond to automatic generation control
signals from the control center)
 Connecting
small, isolated villages to a grid can be expensive
because of the necessary investment in transmission lines, poles,
transformers, and other infrastructure
 Solar PV power come in relatively small size and are best connected
to low voltage lines whereas NBET buys power only at transmission
voltage
5
Policies
l
The National Energy Policy provides for :
 Increase
renewable share of power supply
 The
Draft Renewable energy master plan provides for 18% of the
electricity Installed capacity from renewable energies not including
the existing large hydropower by the year 2020.
 Key
policies to drive the development of solar are as follows:
– The nation shall effectively harness solar energy resources and integrate them
with other energy resources.
– The nation shall promote the use of efficient solar energy conversion
technologies, such as use of photo-voltaic and concentrated solar panels for
power generation.
– The nation shall promote solar energy generation for productive use.
– The nation shall intensify efforts to increase the percentage of solar energy in
the present energy mix.

The following incentives are implied in the feed-in tariff.
 Guaranteed
 Priority
market
Grid connection and offtake
 Simplified
Licensing /permit process
 Concessionary
 Facilitated
l
tariff rates
land acquisition/ site access
Other recommended policy incentives include
 Tax

Feed-in Tariffs
l
Feed-in tariffs refer to a minimum guaranteed price per
unit of produced electricity as approved by the regulator,
to be paid to the producer, or as a premium in addition to
market electricity prices.
l
Regulatory measures are usually applied to impose an
obligation on electricity utilities to pay the (independent)
renewable energy power producer a price as specified
by the government.
l
The level of the tariff is commonly set for a number of
years to give investors security on income for a
substantial part of the project lifetime

Conclusion
l
Nigeria is currently assessing the various regulatory, policy and
incentive options, given that each approach has its pros and cons.
