3 Supply capacity

In July 2013, commercial operation began at Joetsu Thermal Power Station Unit No. 1-2 (output 575.68 MW), and, after determining that it would not compromise supply stability in our own service area, we provided supplementing electric power of up to 1760 MW (Period of peak demand for weekdays from 9:00-10:00 AM) at the request of other electric power companies that foresaw supply shortages.
