UPS Market in Japan: Key Research Findings 2019
Yano Research Institute (the President, Takashi Mizukoshi) has conducted a survey on the domestic UPS (Uninterruptible Power Supply) market and has found out the product trends by segment, the trends of market players, and the future perspectives.
The domestic UPS market size in FY2017, based on the shipment values at manufacturers, declined by 1.9% from the preceding fiscal year to 78,027 million yen, but expected to slightly rise for FY2018 by 1.7% to reach 79,377 million yen.
Although the demand to update large-capacity UPS with 100kVA or more for datacenters somewhat subdued in FY2017, the projects of building datacenters have increased one after another, newly generating the UPS demand. Such a strong demand for UPS for datacenters is likely to lead the shipment volume of UPS products to increase and more users to shift to large-capacity UPS, contributing to expand the market for FY2018.
One of the characteristics of UPS is the small power losses (good conversion efficiency), which makes larger difference in cost as the capacity of UPS becomes larger.
Some UPS with the capacity of 100kVA and larger have adopted low-loss expected SiC to improve efficiency, replacing the conventional IGBT (Insulated Gate Bipolar Transistor). On the other hand, because the products utilizing SiC require higher cost, the makers face a challenge of making a balance between efficiency (performance) and cost.
In addition, UPS with the capacity of 100kVA and more requires more expenses for peripheral parts, installation work, maintenance, and etc. than those with smaller capacity. Some user companies wanting to suppress the initial cost strongly demands the expenses for UPS products to be as low as possible. In such a status, there has been increasing number of UPS products equipped with the parts that have extended the life durability, aiming to reduce the maintenance cost.
