Mobilehome Park Utility Upgrade Program -

Three Year Pilot Program for Voluntary Conversion of Electric and Natural Gas Master-metered Service at Mobilehome Parks and Manufactured Housing Communities to Direct Service by Electric and/or Gas Corporations

MHP Main ImageIn February 2011, following a petition filed by the  Western Manufactured Housing Communities Association (WMA), the CPUC opened a rulemaking proceeding (R.11-02-018) to examine what could be done to encourage owners of mobilehome parks and manufactured housing communities (both referred herein as MHPs) to upgrade aging gas and electric distribution systems in an effort to enhance both public safety and service reliability for MHP residents.

On March 13, 2014, the CPUC closed R.11-02-018 and issued Decision 14-03-021, establishing a three-year pilot program authorizing each California investor-owned utility to convert 10% of master-metered gas and/or electric MHP spaces within its operating territory to direct utility service. Due to overlap in operating territories, the utilities have jointly worked to develop processes and procedures that will allow the implementation of the pilot program to be, generally, uniform and consistent throughout California. All utilities refer to the pilot program as the Mobilehome Park Utility Upgrade Program. The CPUC encourages municipal owned utilities (e.g., SMUD, LADWP, City of Long Beach, MID, etc.) and communication providers to participate in the upgrade program; however, these entities are not mandated to participate in the upgrade program.

The Mobilehome Park Utility Upgrade Program began on January 1, 2015 and with some exceptions, will end on December 31, 2017. Per Decision 14-03-021, there was a 90-day open enrollment period, between January 1 – April 1, 2015, during which the CPUC’s Safety and Enforcement Division accepted initial applications from MHP property owners interested in volunteering to participate in the program. The CPUC made this initial application, also referred to as the CPUC Form of Intent, available as a fillable PDF document for download from the CPUC website. In addition, the utilities provided a statewide utility website to enable MHP owners to complete and submit a CPUC Form of Intent online. For more utility specific information related to the upgrade program, please check the utility website(s) for the investor owned utility(ies) which provide gas and/or electric service to your MHP.

Please note that the CPUC accepted the CPUC Form of Intent ONLY during the open enrollment period of January 1 – April 1, 2015. In year 2017 any party to R.11-02-018 may petition the CPUC to extend its pilot program beyond December 31, 2017; however, there is no way of knowing at this time if the CPUC will actually extend the pilot program beyond that date, or what form or terms would apply to an extended pilot program. Based on what the CPUC decides in 2017, it may establish a new enrollment period to allow MHPs unable to participate in this pilot to submit applications and participate in any extended pilot program. The CPUC provided no guarantees that MHP owners submitting a CPUC Form of Intent will have their master-metered system(s) converted to direct service under the current pilot program. Therefore, it is unlikely that an extended pilot program would penalize any MHPs that applied to the current pilot but, based on selection or time constraints, were unable to have their MHP’s master-metered gas and/or electric utilities converted to direct utility service. For additional information related to the Mobilehome Park Utility Upgrade Program, please review the FAQs for the pilot program.

CPUC Form of Intent

The Form of intent for the second phase of the Mobilehome Utility Conversion Program is now available.  

Ordering paragraph 2 of D.20-04-004 states that "The Mobilehome Park Utility Conversion Program timeline shall accept applications beginning on January 1, 2021, with 2020 allowed as a transition year using the existing prioritization list to reconcile existing Commission Safety and Enforcement Division lists with newly proposed lists consistent with the process following in Decision 14-03-021 and updated in this decision."

The Form of Intent was mailed to all owners of Mobilehome Parks with master-meter gas systems on file with SED.  The Form of intent is also available at the link below:
