Comparison with Major International Electric Utilities

Comparison with Major International Electric Utilities

In order to objectively examine the operational effectiveness of TPC, we compare its performance with 10 well-known major power companies.

This table is based on a comparison of 10 companies larger scales and complete information. A number of criteria were selected for comparison and for use as references in the improvement of TPC’s performance. These included line loss rate, average power outage duration, power sales per employee, thermal efficiency.

Notes:
  1. This table is based on a comparison of 10 companies larger scales and complete information.
  2. Line Loss Rate: KEPCO's performance was better than TPC's because the company uses ultra-high-voltage transmission lines (765 KV) and households use 220 V electricity.
  3. Average Power Outage Duration: Korea outperforms Taiwan because of higher urbanization of power supply areas and automation of distribution. 
  4. Thermal efficiency: South Africa uses HHV and the other countries use LHV. 
  5. Moody's credit ratings: Aaa, Aa1, Aa2, Aa3, A1, A2, A3, Baa1, etc.
    S&P's credit ratings: AAA, AA+, AA, AA-, A+, A, A-, etc.
  6. ROA = Income before income taxes / Average total assets
  7. Power sales per employee =Power sales /Number of employees 
  8. The installed capacities of TEPCO and CHUBU have decreased dramatically because their thermal power generation and other businesses were succeeded by JERA Co., Inc., through an absorption-type company split, effective April 1, 2019
Results and Review

The Taiwan Power Company's performance was above average in the areas of Line Loss Rate, Average Power Outage Duration, and Power Sales per Employee.

The Taiwan Power Company has made continuous improvements in various operating areas over the years. One exception to this is financial indicators. Improvement in this area is limited by the fact that electricity rates do not reflect costs. Despite this, non-financial indicators, such as transmission and distribution efficiency and the quality of power supply, have kept pace with the performances of other major global power companies.
