3
Motivation

• Why is Rural Electrification an issue?
• About half the world's population lives in rural
  communities (between 2 and 3 billion people)
• Electrification plays a vital role in poverty
  reduction and improvement in the quality of life
  in rural communities
• Electricity is essential in the development of
  rural industry as well as agribusiness and
  associated income generation
• It is also essential for sustainable development

4
Socio-economic characteristics of rural
environments

• Low population density
• Low consumption levels
• Marginal cost of serving rural load is high
  compared to urban load
• Low-income levels (typical UN statistic of people
  subsisting on less than a dollar day)

5
Main issues

• How to design cost effective rural
  electrification programmes
• Seek low cost electrification options/solutions
• SWER single wire earth return
• Ready boards to avoid cost of wiring
• Revision of wiring standards?
• Relaxing of voltage quality standards?
• Innovative financing of RE
• How to involve private sector
• Management of subsidies
• Organisation of RE programmes ? social dimensions

6
Terms of reference1
Scope

• Review the methodologies and practices for
  electrification of villages and residential
  areas, including services and craft industry.
• Assess the impact of electrification on the
  generation and transmission system

7
Terms of reference 2
Work Programme

• A review of the existing situation concerning
  rural electrification
• A detailed analysis of the related loads, supply
  alternatives and organisations, to be possibly
  performed by dedicated task forces
• Load characterization typical loads considered,
  on basis of the primary needs requirements and
  including corresponding load profiles, main
  influencing parameters, quality and reliability
  requirements, DSM possibilities, etc.
• Cost-effective load supply alternatives,
  including energy generation, distribution
  configurations and storage capabilities.
  Co-generation, possible use of distribution
  network for communication and consumer interface
  should also be reviewed

8
Terms of reference3
Work Programme

• Organisation organisational structures,
  planning, operation and maintenance principles,
  losses minimisation, metering and billing,
  financing, etc
• An analysis of the impact of electrification on
  system development (review of the methodology for
  realistic system load forecast and establishment
  of the corresponding development strategy)
• The preparation of checklists, guidelines and
  methodologies to be used for the realisation of
  rural electrification programmes
• A symposium on rural electrification for results
  dissemination

9
Deliverables

• Deliverables will consist of
• Checklists, guidelines and methodologies for
  rural electrification programmes
• A paper for Electra
• A symposium
• A presentation to the 2006 Cigré Session and
• A tutorial at 2006 Cigré Session
• Time Schedule
• Start 2003
• End of work 2006

Task forces1
Working Group is organised in 4 Task forces

• Task 1 Classification of loads
• Modelling and forecasting, price elasticity,
• Loads and international standards
• Task 2 Network infeed
• Local MV and LV distribution
• Isolated systems with local generation
• Integration with ICT

12
Task forces2

• Task 3 Organisational aspects
• Institutional aspects (rural development, sector
  reform, national capability),
• Demand and supply side aspects
• Financing policy and subsidies
• Task 4 Impact on power system
• Load Forecasting
• Planning Development of T and D
• Data management

13
Review of past WG activities

• Kick off meeting Brussels, March 2004
• Agreed on tasks and work programme
• Appointed task leaders and members
• Agreed a short term work programme ?preparation
  of keynotes on each task
• Paris meeting August 2004
• Review of keynotes on each task
• Agreed on content deliverable
• Presentation by Sten Bergman on World Bank
  activities in RE ?focus on low cost
  electrification schemes
• Agreed on next steps ?Draft Task reports

14
Schedule of future activities

• Beginning 2005 progress meeting including
  description and discussion of the content of the
  draft report.
• Circa March 2005 Abstracts for 2006 Session.
• Distribution of sections of the draft report.
• October 2005 present draft final report, Cigré
  Southern Africa Regional Conference South Africa
• August 2006 Cigré Session, tutorial - Paris

15
Concluding remarks

• There has been a lot work done on RE worldwide
• CIGRE working group will avoid duplicating
  existing work
• WG will aim to produce work that is useful to
  people in involved in RE planning (Government,
  utility, private sector investors, consultants)

Focus on developing a methodology and good
practice guide for rural electrification
