Preface
This report has been produced by IEA Clean Coal Centre and is based on a survey and analysis of published literature, and on information gathered in discussions with interested organisations and individuals. Their assistance is gratefully acknowledged. It should be understood that the views expressed in this report are our own, and are not necessarily shared by those who supplied the information, nor by our member countries.
IEA Clean Coal Centre is an organisation set up under the auspices of the International Energy Agency (IEA) which was itself founded in 1974 by member countries of the Organisation for Economic Co-operation and Development (OECD). The purpose of the IEA is to explore means by which countries interested in minimising their dependence on imported oil can co-operate. In the field of Research, Development and Demonstration over fifty individual projects have been established in partnership between member countries of the IEA.
IEA Clean Coal Centre began in 1975 and has contracting parties and sponsors from: Australia, China, the European Commission, Germany, India, Italy, Japan, Poland, Russia, South Africa, Thailand, the UAE, the UK and the USA. The Service provides information and assessments on all aspects of coal from supply and transport, through markets and end-use technologies, to environmental issues and waste utilisation.
Neither IEA Clean Coal Centre nor any of its employees nor any supporting country or organisation, nor any employee or contractor of IEA Clean Coal Centre, makes any warranty, expressed or implied, or assumes any legal liability or responsibility for the accuracy, completeness or usefulness of any information, apparatus, product or process disclosed, or represents that its use would not infringe privately-owned rights.

Abstract
Operating ratios are a representation of revenue and expense categories found on a typical financial statement. They are presented as a ratio or a percentage value. The smaller the operating ratio, the greater margin an organisation has to make a profit. Conversely, the greater the operating ratio is, the lower the margin to generate profit. Within operational costs, there are many factors that impact the operational efficiency of a power generating company. These include cost of fuel, staff/personnel, operation & maintenance (O&M) and depreciation and amortisation (the higher these factors are the higher the operating ratio and the lower the operational efficiency). The cost of coal-fired power generation differs not only from one country to another but also from one power plant to another. However, current coal-fired power generation is in competition with renewable energy and thus generation has shifted in many countries from baseload to load following mode necessitating flexibility in power plant operations. As such, frequent cycling of coal-fired power plants can cause thermal and pressure stresses. Over time, these can result in premature component failure and increased, necessary maintenance. Starting a unit, increasing its output, or operating at part load can also increase emissions compared to non-cyclic operation. Assessment and control of operation and plant maintenance costs play a major role in calculating operating ratios. These ratios allow a company to compare its operational performance across various times, analyse its data and take the necessary steps in order to maintain as good an operational performance as possible and as such, as low an operating ratio (%) as possible.
