01/10/2011

As an enterprise with 100% foreign owned capital, the production line of Binh An Co., Ltd is well equipped. This enterprise is specialized in producing fresh water from raw water pumped from Dong Nai River. Power consumption of the company is mainly for water pumping, lighting and air conditioning.

With the aim of improving energy efficiency in enterprises, under the mandate of the Ministry of Industry and Trade’s Energy Efficiency Office, Center of Industrial Promotion and Development Consultancy of Binh Duong has implemented energy audit for businesses in the area. Binh An Water Supply Co., Ltd is one of those businesses.

As an enterprise with 100% foreign owned capital, the production line of Binh An Co., Ltd is well equipped. This enterprise is specialized in producing fresh water from raw water pumped from Dong Nai River. Power consumption of the company is mainly for water pumping, lighting and air conditioning.

With the goal of analyzing, identifying energy efficiency measures, reducing production costs and reducing environmental pollution, the company has implemented energy audit. Thereby, the company has found huge potential economic benefits which help reducing energy costs by over VND 3 billion per year.

Previously, statistics showed that energy costs of the company, including costs for electricity and oil, were nearly VND 14 billion per year. Each month, the company has to spend an average of VND 1.92 billion on electricity.

Through inspection, the energy audit report made by the Center of Industrial Promotion and Development Consultancy of Binh Duong has shown that the company can save a lot of production costs if it implements two solutions which are improving the lighting system and improving the water pumping system.

Efficient lighting

Replacing T10-40W fluorescent lamps using ferromagnetic ballasts with 36W fluorescent light bulbs, the business will reduce 35% of electricity consumed for lighting.

Specifically, with 273 lamps in use, the renovation will help saving nearly 9.8 thousand kWh of electricity per year, equivalent to about VND 13 million per year. Investment capital for the replacement of lamps is VND 22.8 million. So the payback period is estimated to be 18 months.

Improving the water pumping system

With the clean water pumping system, the proposed solution is to install inverters. Test results have shown that one inverter installed for a 28KW water pump will help save 820-825 kWh of electricity consumption, equivalent to VND 1.073 billion.

Currently, the plant has 6 water pumps in alternate operation. Therefore, installing 6 inverters for these 6 engines would save VND 3.22 billion. Total investment capital of this project is VND 3.042 billion. The payback period is estimated to be 1 year.

Thus, with those two solutions, Binh An Water Supply Co., Ltd shall save VND 3.235 billion through reducing electricity consumption by nearly 2.5 million KWh.
