County's Planning Commission
To Consider Enlargement Of
Residential Wind Energy Systems

The Upshot

    The San Bernardino County's Planning Commission will decide on March 6, 2025, whether to approve a Development Code Amendment to increase the allowable kilowattage from 10 kW to 25 kW for residential accessory wind energy systems.

    Currently, the total output allowed is 10 kW for most rural parcels. The commission may approve an increase of 2.5 times, to 25kW.

    Of interesting note, per county ordinance, the current maximum height of 80 feet in rural areas will not be changed for the structures.

    In looking briefly on the Internet (https://www.pvmars.com/product/25kva-25kw-wind-turbine), the proposed new maximum size of a single 25kW wind energy system has a blade diameter of 9.5 meters (31.16 feet). That's equivalent to a 3 story spinning circle.

    A 30-foot diameter blade will probably require a minimum pedestal or mask of over 50 feet and be of a substantial visual structure to handle the weight, torque, and high wind dynamics.

    The current regulations for most rural parcels allow up to five 2kW wind energy systems, according to county planner, Maryn Wells, who I spoke with on February 26, 2025.

    This photo was supplied by the applicant to the county to give a comparison of a 25kW installation. The older and newer models are side by side. The newer model is on the left of the photo, and the older model is on the right. The size of the older unit was not given.

    Unless you want your neighbors to have a few of these adjacent to your home, it is suggested that you write an immediate letter of opposition. Don't expect others to write it for you.

    Should the new proposal of a maximum of 25kW be adopted, up to twelve 2 kW wind energy systems, 80 feet high, would be reportedly allowed on a single parcel !

    Should a blade fail, we could have deadly projectiles flying onto neighboring properties.

    We have small wind-powered generators in Newberry Springs that are reported to produce noise. One small unit near Newberry and Riverside Roads produce, what I would describe as, a very soft whomping sound. A larger unit, probably a 10kW and 80 feet high is midway south on Newberry Road.

    Fortunately, most people go solar rather than wind, however, more wind-generated power may be on Newberry's horizon with eyesore violations of our desert views; and, devaluation of properties.

    This proposal in upscaling is being promoted by a single special interest that has been selling wind-generated power systems in the county for many years. As the units have become more efficient and larger, the seller feels restricted by the existing county ordinance.

    As this technology negatively violates the senses of many residents, installation of these industrial-sized power units should require a Conditional Use Permit.

    Anyone opposed should immediately send an e-mail of opposition titled PROJ-2024-00063  PC Hearing: March 3, 2025, to the county planner, Maryn Wells, Senior Planner, at Maryn.Wells@lus.sbcounty.gov. Please include your name and address.

    Even though copies of your letter might be included in each planning commissioner's binder, my experience is that they don't look at the letters. They only ask the county staff for the number of opposition letters.

    Consequently, I would highly suggest that you CC: your letter to Supervisor Dawn Rowe at
Supervisor.Rowe@bos.sbcounty.gov
and Supervisor Paul Cook at
Paul.Cook@bos.sbcounty.gov
