Public Hearing Notice – Proposed Electric Rate Adjustment
Wednesday, June 15, 2022, at 7:00 p.m. at 10500 Civic Center Drive

For the past 19 years, the Rancho Cucamonga Municipal Utility (RCMU) has taken pride in extending the most reliable and affordable electric service rates to our customers. A Cost of Service and Rate Design study was recently conducted by the Utility to capture the true cost of providing electric service to RCMU customers and to re-examine RCMU’s existing electric rates.

The following recommendations are being proposed to the Rancho Cucamonga City Council for review and approval:

  • Residential Rates: The proposed amendments to the existing residential electric rates will result in rates increasing a little over 2%.
  • Commercial Rates: The proposed amendments to the existing commercial electric rates will result in rates increasing on average between 2%-4%. 
  • After this rate adjustment, all RCMU rate classes will continue to be on average 30%-50% lower than comparable SCE rates.

If approved by the City Council, the revised RCMU electric service rates will become effective July 1, 2022.
