In recent years, Utah has seen significant changes in its solar energy policies, particularly concerning net metering and the compensation rates for excess energy produced by residential solar systems. These developments have substantial implications for homeowners considering solar installations.
This article delves into the current state of solar policies in Utah, focusing on the reduction of solar credits by Rocky Mountain Power and its impact on residential solar adoption.
Understanding Net Metering in Utah
Net metering is a system that allows homeowners with solar panels to receive credits for the excess electricity they generate and feed back into the grid. Traditionally, this system has been instrumental in making solar investments more attractive by offsetting energy costs.
Evolution of Net Metering Policies
In Utah, net metering policies have undergone several transformations:
Pre-2017: Homeowners received credits at the full retail electricity rate for the surplus energy their solar systems produced.
2017 Agreement: A compromise was reached to phase out the existing net metering structure. Customers who submitted their solar applications before November 15, 2017, were grandfathered into the original program until 2035. For new applicants, a transition period was established to study and implement a new compensation method.
Post-2020: For applications submitted after October 30, 2020, Rocky Mountain Power introduced an Export Credit Program. Under this program, excess energy exported to the grid is credited at a rate determined annually, which has been lower than the previous net metering rates.
Recent Legislative Developments
In February 2024, Utah lawmakers advanced a bill aimed at increasing the compensation that Rocky Mountain Power must provide to rooftop solar customers who generate more power than they use. The proposed legislation guarantees that these "net-metering" customers would be credited for 84% of what Rocky Mountain Power charges customers for power. This move is intended to provide greater predictability and fairness for solar adopters.
Implications for Homeowners
The reduction in solar credits and the evolving policy landscape have several implications for Utah homeowners:
Financial Considerations
Longer Payback Periods: With lower compensation rates for excess energy, the time it takes for homeowners to recoup their solar investment has increased.
Incentive to Increase Self-Consumption: Homeowners are now more motivated to use the energy they produce rather than exporting it. This can be achieved by adjusting energy usage patterns or investing in battery storage systems.
Adoption of Battery Storage
Enhanced Energy Independence: By storing excess energy, homeowners can use their solar power during non-sunny periods, reducing reliance on the grid.
Financial Benefits: Utilizing stored energy during peak electricity rate periods can lead to additional savings.
Navigating the Changing Landscape
Despite the reduction in solar credits, homeowners can still find value in solar installations by:
Leveraging Available Incentives
Federal Investment Tax Credit (ITC): Homeowners can deduct 30% of their solar installation costs from their federal taxes. This credit is available through 2032, after which it decreases.
Utah's Renewable Energy Systems Tax Credit (RESTC): As of 2025, this state credit has expired. Homeowners who installed systems prior to the expiration were eligible for a credit of up to $400.
Optimizing System Design
Right-Sizing: Designing solar systems that closely match on-site energy consumption can minimize excess energy generation, thereby reducing the impact of lower export credits.
Incorporating Smart Technologies: Utilizing energy management systems can help homeowners monitor and adjust their energy usage to maximize self-consumption.
Conclusion
The reduction in solar credits by Rocky Mountain Power presents challenges for Utah homeowners considering solar installations. However, by understanding the evolving policy landscape, leveraging available incentives, and optimizing system design, homeowners can still achieve significant benefits from solar energy. Staying informed and proactive is key to making the most of solar investments in this changing environment.
