62-MW Marshall Solar project in Minnesota to be completed this fall

Marshall Solar LLC told the Minnesota Public Utilities Commission in a Sept. 14 update covering the August-September 2016 period that its 62-MW solar project is nearing completion.

The update is required under a Site Permit issued by the commission for the Marshall Solar Energy Project on May 5. Major construction activities that took place from Aug. 15 up to now include:

  • Low voltage cable (DC underground collection network) installation continues and will conclude in the next few weeks. Inverter concrete foundation installation and backfill completed the first week of September.
  • Solar panel deliveries continue at a rate of approximately 24,882 each week. As of Sept. 13, Marshall Solar has received a total of 218,312 panels and is on track to finish panel deliveries as scheduled on Sept. 30.
  • Pile installation is nearly complete across the entire project. Pile installation progress is at a rate of 700-800 per day. This activity is expected to finish ahead of schedule by Sept. 16.
  • Solar panel racking, solar panels, and wire management installation activities are underway and will comprise the bulk of the work remaining. Panel racking installation is also expected to finish slightly ahead of schedule around the week of Sept. 23. Solar panel installation is progressing and accelerating with the addition of nearly 100 construction workers to focus on this task, bringing Marshall Solar’s total workers up to 265 personnel as of Sept. 13. Panel crews are installing approximately 5,000-6,500 solar panels each day. As of Sept. 13 there are 93,442 panels installed out of the 282,296 panels that will be installed upon completion.
  • As panel crews ramp up in production, General Electric mobilized to the Marshall Solar Project in September to begin initial commissioning (testing and equipment checkouts) activities that will continue throughout November and December. Substation testing is underway and is expected to finish on Sept. 15 with end to end testing completion between Marshall Solar’s Clover Substation and Northern States Power’s Lyon County Substation.

Major activities planned for the upcoming September-October reporting period include:

  • Pile, solar panel racking, panel installation, and wire management will continue;
  • Commissioning and testing of the solar array, including all panels and inverters, will commence in September and continue through project conclusion.
