Background

In 2018, the plant was reportedly scheduled to be retired in 2022 when Sumitomo's new 150-MW gas-fired power plant was scheduled to completed.

However, this was uncertain as the gas plant's EIA document did not mention it being a replacement of the coal-fired power station. For example, Sumitomo Joint Electric may decide to close unit 1 or 2 that are burning coal, heavy oil, and biomass, but to keep unit 3 running.
