Net Metering in Utah

Net Metering in Utah

Utah has made great strides on net metering policy, beginning with an ‘F’ grade on a national score card for net metering in 2007 and improving to an A grade in 2009 which has been maintained to this date.  Utah Clean Energy, along with numerous partners and supporters, led the charge to improve Utah's net metering policy with the passage of Senate Bill 84 in 2008.  Net metering rules have been the subject of several Utah Public Service Commission proceedings in recent years, initiated by a request from Rocky Mountain Power in 2014.  To learn more about ongoing net metering proceedings in Utah, please visit Utah Clean Energy's website.

Key provisions of to net metering for Rocky Mountain Power Customers include the following:  

  • Excess kilowatt-hours in any given month roll over to the next month and are credited on a kilowatt-hour for kilowatt-hour basis; these credits accrue during a 12-month annual billing period that runs April through March (in accordance with Utah law).  Any excess kilowatt-hour credits remaining at the end of the 12-month annual billing period 'expire' and the value of these credits is forfeited to the Home Electric Lifeline Program, which provides discounted electricity to low-income customers.
    • Rocky Mountain Power's net metering tariff also offers an alternative annualized billing period for irrigation customers on Rate Schedule 10 that runs from September to October. 
    • Residential customers are able to install solar electric systems up to 25 kilowatts; non-residential customers are able to install systems up to 2 Megawatts (or 2,000 kilowatts).
    • The total amount of net metering capacity allowed on the entire utility system can be up to 20% of the 2007 peak demand for Rocky Mountain Power, which equates to approximately 923,000 kW of net metered installations. The most recent data from Rocky Mountain Power indicates that 32,994 kW of net metered installations have already been completed, which represents 3.5% of the total allowable capacity.  The maximum amount of net metered installations allowed for rural electric cooperatives is only 0.1% of 2007 peak demand (the total amount differs per utility).
    • Large commercial and industrial customers with demand charges that generate excess generation will be given a choice between valuing excess generation at an avoided cost based rate, or valuing excess generation at an alternative rate based on utility revenue and sales contained in FERC Form No. 1.

Utah's Rural Cooperatives and Municipal Utilities

Utah's Net Metering Policy requires Rocky Mountain Power and all Rural Electric Cooperatives to offer net metering. However, Rural Electric Cooperative Boards of Directors are allowed to rule on certain provisions (including the value of excess generation, customer charges, etc.).  Utah's Municipal Utilities are not required to offer net metering, but many allow net metering. Some utilities may assess additional monthly charges to net metering customers – you should inquire with your utility about their policies before making any solar investments.
