Ranking of Global Power Companies

The Taiwan Power Company (TPC) is the only integrated power company in Taiwan. In order to understand the operations of similar foreign power companies, information must be collected on the national electric business so that the operational effectiveness of TPC can be checked. The results of these comparisons can then serve as a reference for the development of TPC's future strategies and the improvement of performance.

The ranking of the power company's installed capacity (see the table below) is mainly based on the Forbes Global 2000 rankings, and the collection of data from other power companies.

According to the data, the top three power companies were China Energy Investment Corporation, China Huaneng Group, China Huadian Corporation. If the five major power generation groups from China are excluded, TPC ranked 18th.

Notes:
  1. The installed capacity of TPC was 33,270 MW in 2018. The company was ranked 18th among integrated global power companies.
  2. "n" represents national data.
  3. 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.
  4. Average Power Outage Duration: Korea and Japan outperform Taiwan because of higher urbanization of power supply areas and automation of distribution. 
  5. Thermal efficiency: South Africa uses HHV and the other countries use LHV.
  6. 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.
  7. Hydro-Québec's Average Power Outage Duration was divided into Distribution (411 mins/household-year) and Transmission (26 mins/household-year).
  8. ROA = Income before income taxes / Average total assets
  9. Power sales per employee =Power sales /Number of employees (Non-Consolidated)

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 CO2 Intensity category mainly depends on a company’s energy portfolio and its compliance with government policy. In Taiwan, restrictions on the development of renewable energy, the use of natural gas and the decommissioning of existing nuclear power plants will lead to a gradual increase in CO2 Intensity.

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.
