4. What is EG
• EG is generation embedded
within a distribution network
• EG also called:
Distributed generation
Decentralised generation
• EG is not a new phenomenon.
It preceded centralised
systems
Utility scale
generators
Transmission
grid
Distribution
grid
EG
(consumers)
EG
(dedicated)

5. Why EG?
• Reduced need for large-scale generators
• EGs not necessarily more expensive (scale economy, less permits required)
• EGs are quicker to deploy
• Reduced need for transmission infrastructure
• Reduced transmission losses
• Increased system reliability/resilience
• Supply and demand matching
• Reduced need for peaking plants
• Customisable and more efficient
• Increased local economic development (SME involvement)

6. Options for EG
Includes many of same technology options
for utility scale
• Conventional technologies
• Primary fossils (Gas/Oil/Coal)
• Diesel
• Hydro
• New Alternatives
• Solar
• Wind
• Biomass
• CHP
• Co-generation
• Tri-generation

7. More about RE…
• RE is better suited to EG for
some key reasons:
• scalability
• location flexibility
• environmentally sustainable
• RE technologies are now
established and reliable

10. Case for EG in Nigeria
• Reduced need for large-scale generators
• Reduced need for transmission
infrastructure
• Reduced transmission losses
• Increased system reliability/resilience
• Supply and demand matching
• Reduced need for peaking plants
• Customisable and more efficient
• Increased local economic development
(SME involvement)

11. EG Status: Nigeria
• 20 GW from private
generators of back-up power,
most not grid tied
• EG not a success by any
means
• It is however now receiving
attention under the new power
sector reforms

12. EG regulations in Nigeria
• Regulations for Embedded
Generation 2012
• Regulations for Captive
generations 2012
• New regulations for
procurement of generation
capacity 2014 (exemptions for
<10MW)
• Distribution Code v01

13. RE Development in Nigeria
• Implementation status
• Market interest
• Regulations
• Policy support
Targets (MW)
Short Term
(2005-2007)
Medium Term
(2008-2015)
Long Term
(2016-2025)
Hydro (large) 1930 5930 48,000
Hydro (small) 100 734 19,000
Solar PV 5 120 500
Solar Thermal 1 5
Biomass 100 800
Wind 1 20 40
All 2,036 6,905 68,345

14. RE Potential: Solar

15. Main challenges
• Targeted policy support
• To RE industry
• To market structure
• Infrastructure

16. Way forward
• Stakeholder consultation
• Resource assessment
• Grid capacity assessment
• Market studies
• Awareness raising
• Skills transfer
