The energy audit is inspection activities and survey of a power system unit to assess the rationality and efficiency in the designation and operation of the system comparing to the standards and specifications norms.
The energy audit is inspection activities and survey of a power system unit to assess the rationality and efficiency in the designation and operation of the system comparing to the standards and specifications norms.
The energy audit helps enterprises to see clearer how is the energy consumption of various types of machinery and equipment. Currently, this helps identifying the parts, making waste of energy, identifying conservation opportunities and proposing the solutions to conserve energy. The implementation of the solution according to the conventional energy audit is the simplest solution. The investment cost is not too high and bring good economic efficiency.
The results of audit report show the potential in energy efficiency and conservation and the abilities to apply solutions to each type of enterprise. Energy efficiency and conservation could conserve 5% to 40% total energy consumption. In addition to apply new technologies, the audit also made recommendations about energy management policy, process improvements and reduce energy costs more than 10%. Therefore, the amount of investment in capital of energy efficiency and conservation solutions can be refunded in 1-2 years, even shorter, depending on the causes of wasting energy and the corresponding types of solutions.
In 2015, Rang Dong Plastic Joint Stock Company to save more than 1.6 billion/year by implementing solutions of energy conservation and use the energy efficiency and conservation. With the implementation energy conservation initiative with the assistance of Energy Conservation Center City. Ho Chi Minh, Rang Dong Plastic Joint Stock Company has obtained great effect after the investment alternative modern technologies and energy efficiency. The energy conservation report indicated energy sources, mainly consumed simultaneously offering solutions aimed at saving energy, efficient energy use for the company. For example, just by replacing T10 to T5 bulbs, replace high-pressure lamps with compact fluorescent light bulbs, replacing method get natural light and re-planning workshops, lighting system, the company has saved over 130,000 kWh/year, nearly 260 million VND.
Besides, there were some bigger investment solutions such as installing inverters for extrusion machines, laminating machines, PL100 machines, 14 machines, coater HK1200, sheet extrusion machine 12B, 12A at the game machine tole wizened, 12B, 12B sheet extrusion machine, 6-color printing machine, granulating machine,... have helped over 800 businesses benefited million per year from the energy cost reduction. Moreover, according to the figures in the report of energy conservation Center City Energy saving. Ho Chi Minh, Rang Dong Plastic Joint Stock Company is still potential for energy efficiency to 15% of the investment in technology solutions such as installation of inverters for air compressors, replacing an air conditioning chiller is used in high-performance, high performance blowers.
In 2016, Coconut Processing Plant Phu Hung, Ben Tre is one of the units have achieved many tangible benefits of implementing saving energy solutions by energy conservation. Follow the audit report, mainly causes wasteful energy production and push prices higher by the boiler system is old, low operating efficiency, in addition to the fuel is burned for fuel oil boilers have relatively high price on the market. Phu Hung has decided to carry out new investments boiler, fuel change into husks, insulation devices with a high surface temperature. Besides, the consultant also found the energy conservation potential that a huge energy will be saved at the manufacturing's lighting system, change the system consultant, lighting equipment, make the most of natural light or system 1.2m fluorescent lights T5 electronic to conserve power.
According to calculations by the consultant energy conservation, the total investment of the energy conservation measures in the coconut processing plant in Phu Hung were approximately 76.6 million. In the solutions that the consultant proposed solution has the longest payback period less than 2 years, the solution has the shortest payback period is 5 days. Implement solutions simultaneously on estimated annual can conserve nearly 61,600 kWh.
In fact, the energy audit results figures out where wasting energy are as well as energy conserve capabilities in the enterprises. Performing the energy conservation solutions based on energy audit can make the enterprises get the energy conservation opportunities effectively, establishing appropriate management of using energy, reducing costs, increasing profits and improve competitive position.
