Sumitomo Corporation completes the construction of the geothermal power station for Mighty River Power Ltd. (New Zealand)

Sumitomo Corporation (President and CEO: Susumu Kato; Head office: Chuo-ku, Tokyo; hereinafter, "Sumitomo") has completed the construction of the 140-megawatt Nga Awa Purua Geothermal Power Station, for New Zealand state-owned power company, Mighty River Power Ltd. (CEO: Doug Heffernan; Head office: Auckland, New Zealand; hereinafter, "MRP"). The Fuji Electric Systems steam turbine installed at the power station boasts the world's largest single-unit output (as of May 2010).

 

The Nga Awa Purua Geothermal Power Station was established in the Rotokawa area, north of Lake Taupo, roughly in the center of the North Island of New Zealand. In March 2008, Sumitomo Corporation signed a full turn-key contract (including civil and installation) with MRP. After a construction period of about two years, starting May 2008, we completed handover of the finished power station in April 2010, one month earlier than the appointed date of delivery. Fuji Electric Systems offers advanced technologies and a great deal of experience in the manufacturing of turbines resistant to corrosion--a necessity for geothermal power generation. Thus, following closely on the heels of the construction of the Wayang Windu geothermal power station (110MW) in Indonesia in February 2009, the manufacturer has also delivered a turbine for geothermal power generation encompassing the world's largest single-unit output.

 

On May 15, 2010, the opening ceremony of the power station was held with the participation of New Zealand Prime Minister John Key and other relevant parties from Sumitomo Corporation, MRP and Fuji Electric Systems. Takahiro Moriyama, Director, Senior Managing Executive Officer (General Manager of Infrastructure Business Unit) of Sumitomo Corporation commented, "New Zealand pioneered large scale geothermal power generation over 50 years ago. The Nga Awa Purua plant is a major addition to that proud tradition. We are excited by the current New Zealand  geothermal renaissance."

 

Geothermal power generation is attracting attention as a renewable energy source, and a growing number of countries with geothermal resources are keen to develop them. Against the backdrop of our proven past performance in successful implementation of contracts, we will make further efforts to develop more geothermal power generation in the future.
