Contributing to the environment and our future through natural delivered energy power generation

With the technology and knowledge we have cultivated through electrical equipment construction and large-scale power transmission line construction, we entered the field of renewable energy in 1999, at the dawn of the industry and have built up an extensive track record. We provide comprehensive services from power plant installation consulting to the start of operation.

Wind power

Track record: Over 400 wind turbines

We have introduced a wide variety of heavy machinery and cranes to address the recent upsizing trend in WTGs and improve our construction efficiency.

Solar power

Track record: Over 100 sites*Number of site with a total capacity of 500 MW or more

We are able to handle solar power generation components from a variety of manufacturers both domestic and international. We plan, propose, design and construct optimal panel layouts to suit the topography of mega solar sites.

Other natural delivered energy

Biomass power plants, and small hydro power plants
