Toshiba Mitsubishi-Electric Industrial Systems Corp (TMEIC) announced Oct 24, 2019, that it has delivered products including PV inverters as a set to a 70MW mega (large-scale) solar power plant located in Chiayi County, Taiwan.

Specifically, TMEIC sold "Solar Ware Station," which is packaged with PV inverters, step-up transformer, high-voltage interrupter, etc, to the plant. It enables to reduce construction cost by, for example, simplifying on-site work.

The solar power plant was built by Vena Energy Taiwan Solar Energy Ltd (Taipei City), which is a subsidiary of Singapore-based Vena Energy. Vena Energy is one of the largest renewable energy IPPs (independent power producers) in the Asia-Pacific region and owns 11GW of renewable energy-based power plants that are operating, being constructed or being planned. It deals with the development of solar and wind power generation projects as well as engineering, construction and management services for solar and wind power plants.

The Taiwanese government has a goal of increasing the ratio of renewable energy-derived electricity to all the electricity generated in Taiwan from 4% to 20% by 2025 with 20GW of solar power plants. The latest project is the first mega solar project carried out by an IPP in Taiwan, according to TMEIC.

The Solar Ware Station houses PV inverters and their peripheral devices in a container. Before being shipped from a manufacturing plant, the devices of the Solar Ware Station are assembled and wiring is completed so that it can be shipped as a completed product and installed at the site of a power plant.

With "One-stop Solution," on-site installation work, etc are reduced, enabling to reduce construction cost and ensure a high system quality and ease of maintenance.

With a direct-current (DC) input of 1,000V and a rated output of 4.4MW, the Solar Ware Station can be used in severe environments such as high-temperature regions and regions with salt damage.

"TMEIC will continue leveraging our extensive experience to benefit customers around the world," said Naotada Sawada, vice president, Renewable Energy & New Technology Division, TMEIC. "We aim to capture the top share in the PV market in Taiwan as well, where growth is anticipated."
