Kyocera Corporation has started testing Japan’s first ‘self-wheeling’ energy system, developed using a storage battery earlier this month in Shiga Prefecture, Japan.
Self-wheeling is a system in which a company’s self-generated electricity is supplied to its own factory or office located at a different site using an existing electrical power grid.
Kyocera constructed the 150 kW Yasu Kamiya Solar Power Plant on 2,000 m2 land owned by Yasu City in Shiga. Renewable energy generated at the site will be supplied to the Kyocera Shiga Yasu Plant, approximately two kilometres away via the Kansai Transmission and Distribution, Inc’s electrical power grid.
This is Japan’s first test using a stationary lithium-ion battery to control the site’s power generation supply imbalance and enable a stable renewable energy supply while eliminating impact on the grid.
In addition, the Supply and Demand Management Center at Kyocera’s Tokyo Office will conduct high-precision supply-demand management operations to reduce the plant’s demand imbalance.
