TDPUD 2026 Electric Master Plan Initial Study and Appendix G Checklist

The Truckee Donner Public Utility District has developed the 2026 Electric System Master Plan to serve as a technical assessment and strategic roadmap for the planning, operation, and modernization of its electric distribution system. Spanning a five-year planning horizon from 2026 through 2030, the plan is designed to ensure safe, reliable, and affordable electric service while incorporating updated system modeling, findings from the 2024 Integrated Resource Plan, and anticipated community growth. The assessment identified 60 critical constraints and 62 minor issues, leading to the proposal of 30 specific projects with an estimated total investment of 19,681,178 dollars. To comply with regulatory requirements, the District conducted an environmental review under the California Environmental Quality Act, resulting in a Negative Declaration and an Initial Study confirming that the master plan does not constitute a project with direct environmental impacts. A public review and comment period was held from September 18, 2026, to October 19, 2026. The plan focuses on infrastructure upgrades, reliability and resilience measures, and modernization work within the district's service territory in Nevada County, California, and is intended to be updated on a recurring five-year cycle.
