Hoku Materials, a wholly owned subsidiary of Hoku Corp. that manufactures, markets, and sells polysilicon for photovoltaic modules, says it has connected its Pocatello, Idaho, polysilicon production plant to Idaho Power's substation and is receiving permanent power as the company continues with plant commissioning.
‘Connecting to the 82 MW Idaho Power grid-connected substation is a critical milestone,’ says Scott Paul, CEO of Hoku Corp. ‘The power infrastructure for the plant is complete, and we now have 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,’ he continues. ‘These reactors are the largest consumers of power on-site, requiring very large loads of continuous power – they cannot be run on temporary power or portable generators.’
Several miscellaneous tasks remain to be completed before production can officially begin, Paul notes.
