Thai Society and Omron Maximizing energy efficiency for sustainable growth

Is greater convenience making higher electricity bills a problem?

A hot summer in Asia—When you come home, a cold drink in the fridge awaits you. Even in the hot night when it would be hard to sleep, air-conditioning allows you to comfortably fall asleep. We are surrounded by a variety of products that make our lifestyles more comfortable and convenient. As factories make more and more products designed for convenient living, the amount of energy used in factories is also on the rise. Whether at home or in production sites, there could be no end to worries about high electricity costs.

Although Thailand has been enjoying continuous economic growth, the nation relies on imports from neighboring countries for 90% of its power supply. This has resulted in higher electricity charges among ASEAN countries, which in turn is heavily impacting household finances and becoming a constraint for the nation’s economic growth. To cope with these problems, there are increasing activities to use energy more efficiently. Ongoing initiatives include the effective generation of renewable energy and reduction of energy consumption at factories. Used in many countries around the world, Omron technologies enable efficient generation and usage of energy. We believe that these technologies will help bring electricity costs down, thereby contributing to sustainable development of Thai society.

Keeping household electricity bills as low as possible

Generating electricity we use on our own and selling the remaining amount of electricity to a utility company—if we can do this, we will no longer have to worry about electricity bills, even as we enjoy comfort and convenience.

Omron has developed a photovoltaic inverter for solar power generation systems by drawing on our expertise in sensing and control. The PV inverter is designed to convert DC power generated by solar panels into AC power usable at home. Omron PV inverters enjoy a great deal of popularity in Japan, with a cumulative production quantity exceeding 1 million. This makes Omron the leader in the residential PV inverter market in Japan, making a considerable contribution to the increasing prevalence of renewable energy.

Aiming to reduce energy costs at manufacturing sites

Omron technology has not only proved beneficial to family households, but has also helped reduce energy usage at manufacturing sites. For Omron as a manufacturer, reducing energy consumption at its own factories is one of the biggest challenges. At Omron factories, we consider energy consumption to be a part of our manufacturing costs, and have succeeded in efficiently reducing energy usage. Specifically, we made the amount of energy consumed on the factory floor instantly visible to the entire factory staff, so that all workers can check out each machine’s data and contribute energy-saving ideas. This has enabled continuing improvements in the efficiency of energy usage, for instance by cutting the use of electricity while no products are being manufactured. These and other contributed ideas have allowed us to reduce the amount of electricity used for production by 19.4% in two years, without compromising productivity. The energy-saving efforts of Omron factories are highly recognized in Japan, including the company’s winning of the Minister of Economy, Trade and Industry Prize in the Energy Conservation Grand Prix program.* Omron’s energy visualization technology for efficient use, supported by our experience at our own factories, remains active in promoting energy conservation for manufacturing sites of our customers worldwide.

To make more efficient and effective use of electricity

For worry-free everyday use of electricity at home, and for building factories that consume less energy for production, Omron will continue to develop new technologies and offer new solutions.

To improve people’s lives …
Machines can do much more to unleash human potential.
