It is extremely gratifying to be involved in the creation of such a significant manufacturing facility, such as the Moses Lake project, which will be the standard for many years to come,” said Michael Dias, President and Chief Executive Officer of Contra Costa Electric. “Renewable solar panels are in greater and greater demand and the need for solar grade polysilicon is at an all-time high,” said Randy Wagner, President and Chief Executive Officer of Dynalectric Company of Oregon. “This is an extremely important facility for REC, and we are pleased to contribute to this project.”
