  2. TRANSMISSION AND DISTRIBUTION (FACTS & FIGURES)
(i) Service Delivery at the CEB
The response time to the requests of customers is a very important aspect of service delivery and requires close monitoring. 
  • The first KPI (KPI fins) indicates the average number of days between an application being lodged at the CEB and the first site visit to the customer’s premises.
  • The second KPI (KPI p2mv) indicates the average number of days between payment being made for a new supply and the effective connection to the CEB grid.
  • The third KPI (KPI ins(AP)) indicates the average number of days taken for processing CEB’s Clearance for the purpose of Building and Land Use Permit.

(ii) Reliability of Supply
The CEB is committed to improving its reliability of supply and preventing power interruptions by the continuous monitoring of its SAIDI and SAIFI indices in line with best international practices.
 
Table 1.0 and 2.0 below provides for SAIDI*, SAIFI** and CAIDI figures for the past years.

* SAIDI is the System Average Interruption Duration Index i.e. the average duration of interruption of electricity experienced by a customer during the year.

** SAIFI is System Average Interruption Frequency Index i.e. the average number of times a customer has experienced interruption of electricity during the year.

The maximum peak demand for the review period was 462.10 MW and was recorded on 20 January 2021 at 11.00 hrs. This represents a decrease of 8.89%, compared to the maximum demand of the previous corresponding period (507.2 MW), which was mainly due to the contraction in economic activities resulting from the lockdown period. The approximate load distribution on a regional basis at the time of maximum demand is shown hereunder. The yearly maximum demands for period 2014 to 2021 are also depicted.
