Outline
•Background •What is embedded generaJon (EG)? • Issues in EG •Requirements for successful EG regime •Renewable Energy as EG opJon for Nigeria •RecommendaJons going forward
Background: Conventional grid system

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
Transmission grid
Distribution grid
Utility scale generators
EG (consumers)
EG (dedicated)
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)
Options for EGIncludes 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

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

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)
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
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
RE Development in Nigeria
• Implementation status
• Market interest
• Regulations
• Policy support

Main challenges
• Targeted policy support
• To RE industry
• To market structure
• Infrastructure
Way forward• Stakeholder consultation
• Resource assessment
• Grid capacity assessment
• Market studies
• Awareness raising
• Skills transfer
