This is a Base Bid solicitation document from the United States Department of Agriculture Forest Service for the Shake Creek Guard Station Hybrid Electric project located in Elmore County, Idaho, within the R-4 Intermountain Region of the Sawtooth National Forest under the Fairfield Ranger District.

The project includes installation of a new hybrid power system by adding solar-powered generation capacity to the existing generator and distribution infrastructure at the guard station. Key technical requirements include: ensuring the existing generator remains operational with proper ground and neutral bonding per site specifications; establishing an autostart circuit connecting remote circuitry to the two-wire start and stop circuit with coordinating generator startup services; and installing a feeder circuit from the generator into the Flexware electrical system. The system must incorporate four solar modules with proper mounting infrastructure, multiple charge controllers for battery management, and a complete battery bank with remote temperature sensors. All equipment connections require proper grounding electrode systems and electrical safety measures. The design includes specific restrictions on equipment usage during operation, such as prohibiting incandescent and fluorescent lighting while requiring LED alternatives, and limiting microwave oven and tool use. Required signage must indicate electrical hazards at appropriate locations with minimum 1.5-inch high text including maximum voltage, current specifications, and arc flash hazard warnings. The base bid also includes an Option Item #1 for the Big Smoky Guard Station Hybrid Electric installation in Camas County with similar system requirements and specifications. Construction documentation and technical drawings are provided showing generator shedding, site distribution, battery bank layout, and solar array mounting details with complete one-line schematics of the Flexware electrical system components.
