Blue Lake Rancheria Microgrid

Since September, SERC’s microgrid team has been engaged in intensive design work with partners Blue Lake Rancheria (BLR), Pacific Gas & Electric (PG&E), Siemens, Tesla, REC Solar, GHD, Idaho National Labs (INL), Robert Colburn Electric, and Kernen Construction. Commissioning of the microgrid is scheduled for October 2016, and we are keenly aware of how much work there is still to do.

Meeting the commissioning schedule requires strategic planning, hard work, and close coordination. Our implementation methodology involves an integrated design approach, with engineers and contractors collaborating on development construction plans as well as equipment and operational specifications. Design reviews and cost checks are programmed into the schedule at the 50% and 90% levels to build and maintain consensus among stakeholders and to determine if value engineering is required as we work towards construction-ready plans. One critical path is obtaining the necessary approvals from PG&E; we have worked to expedite aspects of that process that are under our control.

We accomplished several important milestones in January. The 50% design review and cost check were conducted, and the results indicate that no major course corrections are needed. Our Early Start design package was released for construction on schedule. We also submitted our interconnection application to PG&E.

Looking ahead, we are scheduled to release the design for construction in June, which is also when Siemens is scheduled to complete Factory Acceptance Testing on the microgrid controller. INL will then conduct hardware-in-the-loop testing of the controller in their real-time digital simulator prior to installing it at BLR in September. Meanwhile, construction will be ramping up as the weather dries out this spring.
