  construction and installation of the 33kV
  Transmission Network. To further improve the
  integrity of the transport capacity of the
  Freetown T D Networks
• JICA phase I project supply, construction and
  installation of 11/33kV Network from Kingtom via
  Congo town, Congo Cross and Wilberforce to
  Regent
• NPA management has maintained the existing TD
  network capacity 35 - 40MW
