Inpex Corp announced Aug 18, 2015, that Inpex Logistics (Japan) Co Ltd has completed a mega (large-scale) solar power plant in Joetsu City, Niigata Prefecture, and had a ceremony to celebrate the completion.

Inpex Logistics (Joetsu City, Niigata Prefecture) is a subsidiary of Inpex. The plant transmits about 2MW of electricity to a power grid. It is the second mega solar power plant of the Inpex group. The power producer for the plant is Inpex Logistics.

The mega solar plant, "Inpex Mega Solar Joetsu," was built on land that Inpex owns in Joetsu City. It started power generation in July 2015 and sells all the electricity to Tohoku-Electric Power Co Inc. The plant is expected to generate about 2,850,000kWh of electricity, which is equivalent to the amount consumed by 860 households, per year.

About 2.513MW of solar panels were set up at the plant. It is about 25% higher than the output for grid connection. As a measure against snow, the panels were installed at an angle of 30° and at a height of 1.4m.

Chiyoda Corp provided EPC (engineering, procurement and construction) services. For the plant, Solar Frontier KK's CIS-based solar panel and Toshiba Mitsubishi-Electric Industrial Systems Corp's (TMEIC) PV inverter were employed.

On an area adjacent to the plant site, Inpex built a solar power plant with an output of about 2MW in March 2013. The Inpex calls the two plants (total output: about 4MW) in Joetsu City "Inpex Mega Solar Joetsu."
