Studies show that sectors such as oil and gas as well as manufacturing have significant potential to improve energy efficiency through solutions that cut across sectors as well as sector-specific measures. For industrial plants, an energy audit is the first step in understanding these opportunities, but many plants do not have the capacity to conduct such audits on their own.
There is significant potential to grow energy efficiency in Indonesia, which offers more than half of Southeast Asia’s energy efficiency investment potential from now until 2020 (OECD/IEA, 2014). The Indonesian government has prepared basic market-setting standards and labelling programmes to support energy efficiency for industry.
TÜV SÜD has also played a part in growing energy efficiency in Indonesia through energy audits for oil rigs. These audits included surveys as well as inspections, tests and measurements through combustion analysis, heat analysis, infrared thermography and power quality analysis. Other methodologies used included vibration, discharge loss, suction loss, liquid flow measurement, air flow measurement, refrigerant cop analysis, and lux/lumen analysis.
These inspections, tests and measurements enabled TÜV SÜD to establish the efficiency of the different types of equipment and their contribution to total energy consumption. The energy audits also served to determine the energy consumption scheme and baseline that guide the client company’s energy usage, to ensure that electrical systems worked according to standards and specifications, and to find opportunities to save energy in oil rigs.
At the end of the process, TÜV SÜD issued a final report on the data gathered during preliminary survey, document review, visual inspection, tests and measurements. The energy audit report provided the client with the technical conclusion and analysis as well as recommendations to improve energy efficiency.
