Abstract
This study estimated loss targets for the transmission licensee and the five distribution licensees of Sri Lanka over the period 2016 – 2020. Both technical losses and the nontechnical losses at each component of the network were estimated largely using the data received from all the licensees, and the targets were set mainly considering the reduction of non-technical losses in the system.
Highlights
Sri Lanka electricity tariff methodology requires to specify an annual regulatory allowance for losses for the transfer of energy over the Transmission Licensee’s network as well as through the Distribution Licensees’ networks
Each licensee should abide by the loss target set by the regulator, the Public Utilities Commission of Sri Lanka (PUCSL)
The total energy loss in both transmission and distribution were reported to be 11.5% of net generation in 2014, whereas the target set by PUCSL was 12.4%
Summary
Introduction Sri Lanka electricity tariff methodology requires to specify an annual regulatory allowance for losses for the transfer of energy over the Transmission Licensee’s network as well as through the Distribution Licensees’ networks. The total energy loss in both transmission and distribution were reported to be 11.5% of net generation in 2014, whereas the target set by PUCSL was 12.4%. This study provides an in-depth analysis of transmission and distribution losses, to separate the technical and commercial losses in each segment of the network and its equipment to establish reasonable losses to be allowed for each licensee, over the period 2016-2020.
