Tribal Community Microgrid

San Pasqual Band of Mission Indians | California | Owner’s Engineer | 2019 - ongoing

• Partnered with Prosper Sustainably and Sage, working on behalf of the Tribe, to model, right-size and provide conceptual design for a microgrid system capable of making the Tribal operations Zero Net Energy. The project was submitted and awarded a $2M grant from the DOE Office of Indian Energy.

• The project is sized at 160kWp of solar PV shade structures and 120kW/480kWh of energy storage.  

• The connected facilities include the Tribal Hall and Administrative Offices, Community Center, Police Station, Fire Station, Wastewater Treatment Plant, and Educational Center & Preschool. Scope includes Owner’s Engineer throughout the conceptual design, bidding and procurement, construction and commissioning process.

• Performed a feasibility, cost-benefit, and electric rate analyses for the site and for the combined microgrid system installation, including reconfiguration of the metering and integration of the facilities served. Delivered each component of the project on time and within budget constraints. 

• It is estimated that the Tribe will save $1.7 million in electricity costs over the next 25 years and gain the value of a resilient and reliable electric service.
