Additional Support

  • Procurement support
  • Developing local standards for grid connection
  • Facilitating group applications for grid connections
  • Training of local electricians for in-house wiring
  • Training of consumers in energy use and efficiency
  • Ex-ante savings for connection fees
  • Introduction of installment payments of the connection fee linked to the electricity bills


Lessons Learned

  • Some utilities are not interested in grid densification
  • Poor households are often excluded in extension projects
  • Some utilities have great difficulties to organize efficient procurement processes causing severe delays
  • Free rider effect difficult to avoid (efficient selection process or accept the effect)
  • Detailed monitoring is considered a burden and not always implemented
  • In several countries power generation capacity cannot keep up withgrid extension
  • In rural areas several households are connected to a meter to save the connection fee which can be legal or illegal according to national and local regulation. In some of these case voltage drop can be a severe problem
