On November 29, Tohoku Electric Power Network began construction of a mega-solar (large-scale solar power plant) with an output of 1.5 MW, "Hikari no Chikara Kurinoe" on Sado Island. It will supply electricity to the island as a non-FIT solar power plant that does not rely on the feed-in tariff system (FIT).
3432 single-crystal silicon solar panels will be installed. Annual power generation is expected to be approximately 1,580,000 kWh, which is equivalent to approximately 500 ordinary households. The solar panel will be made by China's DMEGC, and the power conditioner (PCS) will be made by Fuji Electric. It is scheduled to start commercial operation in December 2023.
In order to further expand the introduction of renewable energy on Sado Island, the company is working to realize optimal supply and demand control that combines renewable energy, storage batteries, internal combustion power generation, and energy management systems (EMS). The new mega-solar plant will be a part of that.
In this initiative, in addition to mega solar, a large-capacity storage battery system with an output of 5 MW and a capacity of 5 MWh or more will be installed on the premises of an existing thermal power plant. The Sado Electric Power Center, which is the master station of the EMS, controls the operation and output of these energy resources. It also performs demand response (DR) for demand-side equipment. Operation is scheduled to start in 2024.
