Okinawa Electric Power Company from August 8, 2014, Kyushu Electric Power from September 25, and three shikoku power companies, Hokkaido Power, Tohoku Power from October 1, are pending the solar power grid connection procedure. Although it is five now, but there is also a view of "further expansion".

Following Okinawa Electric Power Co. having stopped the solar power feed-in purchases on August 8, On September 24, Kyushu Electric Power Co. announced that it would halt the purchase of green electricity in the whole Kyushu region, starting the next day, including putting on hold some 70,000 plans for generation of green power by entities that have applied to Kyushu Electric for contracts to sell the electricity. Kyushu Electric decision affected not only the renewable energy businesses but also local governments, including the Kumamoto prefectural government, which had pushed for introduction of green electricity. Hokkaido Electric Power Co., Tohoku Electric Power Co. and Shikoku Electric Power Co. followed the Kyushu power firm with a decision to suspend the purchase of green electricity beginning this month. Tokyo Electric Power Co. and Kansai Electric Power Co. have also halted such purchases in some parts of the areas serviced by them.
In making their moves, the power companies have cited a clause in the Law on Special Measures Concerning Procurement of Renewable Electric Energy by Operators of Electric Utilities, which exempts them from the duty to buy green electricity if the purchase of such power poses a danger to stable supply of electricity.
The increases solar power generation, supply and demand balance of power is lost and the possibility of large-scale power outage is increased?
Behind their moves is a significant increase in the volume of solar electricity they have had to agree to buy. Solar energy operators rushed to make last-minute applications for electricity sales to the electricity companies before the government lowered on April 1 the prices at which the utilities must buy power from various renewable energy sources. The utility firms explain that if all the electricity from renewable energy sources is supplied to their transmission grids, the total supply will exceed their capacity, which could lead to stoppage of their power generators.
They also say that the fierce ups and downs in the output of solar and wind power due to weather changes will make it extremely difficult for them to adjust the output of their power generators to deal with the fluctuations. If the adjustments fail, it could damage their power grids.
Both cases could result in power outage.
