Overview l.jpg
Overview

  • Motivation

  • Social-economic characteristics of rural areas

  • Main issues in rural electrification

  • WG Terms of reference

  • Deliverables and Time schedule

  • WG Membership

  • Task forces

  • Review of activities – past and future

  • Concluding remarks


Motivation l.jpg
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


Socio economic characteristics of rural environments l.jpg
Socio-economic characteristics ofrural 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)


Main issues l.jpg
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


Terms of reference 1 l.jpg
Terms of reference…1

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


Terms of reference 2 l.jpg
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;


Terms of reference 3 l.jpg
Terms of reference…3

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


  • Deliverables l.jpg
    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 tutorialat 2006 Cigré Session

    • Time Schedule
