Hoku Corp CEO Scott Paul said the power infrastructure for the plant is complete, and the company now has continuous electricity.

"Previously we have been using temporary power and portable generators for localized construction and commissioning activities."

"Connecting to the substation enables us to complete system-wide commissioning activities, including our instruments and control systems, and power-hungry equipment like pumps, compressors, and our polysilicon deposition reactors," Paul said.

Hoku Corp is a solar energy products and services company with three business units: Hoku Materials, Hoku Solar and Tianwei Solar USA.

Hoku Materials manufactures, markets and sells polysilicon for the solar market from its plant in Pocatello, Idaho.
