Draft Renewable Energy Ordinance Available for Public Review

A draft ordinance updating Napa County’s development regulations for renewable energy systems has been released for public comment. Notable components are:

  • Codifies County’s current practices of allowing ‘accessory renewable energy systems’ such as small solar systems as a matter of right, but limits the system to meeting on-site power needs of private residences, business, and agricultural uses. Applies ministerial development standards consistent with other allowed accessory uses.

  • Establishes regulations for ‘commercial renewable energy facilities’ for power generation facilities that provide feed-in tariff power to the public utility grid.

    • Codifies County’s current practices of allowing emergency power generators for use during power outages. Generators limited in size to meet on-site power needs only.

    • These uses are excluded from agricultural and residential zoning districts, and allowed with a Planning Commission Use Permit in industrial, commercial, and public facility districts.

    • Establishes comprehensive development standards for such uses

  • Repeals antiquated ‘small wind energy’ code requirements that expired in 2017.

    Please direct comments or questions via email to John McDowell or call him at (707) 299-1354. A public hearing before the Planning Commission is tentatively set for November 20, 2019. Upon conclusion of the Planning Commission’s recommendation, the draft ordinance will be scheduled for a public hearing before the Board of Supervisors.
