Quick Answer
NET METERING POLICIES WILL CONTINUE TO EVOLVE TO BALANCE RENEWABLE ENERGY GENERATION WITH GRID STABILITY AND UTILITY COMPANY PROFITS, WITH EXPECTATIONS OF INCREASED STORAGE REQUIREMENTS AND NET METERING CAPS IN THE COMING YEARS. STATES WITH STRONG RENEWABLE PORTFOLIOS WILL LIKELY SEE MORE AGGRESSIVE POLICY CHANGES, WHILE OTHERS MAY FOCUS ON INCENTIVIZING STORAGE AND DEMAND RESPONSE. REGULATORS WILL NEED TO FIND A DELICATE BALANCE TO SUPPORT RENEWABLE GROWTH WHILE MAINTAINING GRID RELIABILITY.
Changing Regulatory Landscape
Utilities and regulators are reevaluating net metering policies as the solar industry continues to grow. In 2020, Nevada reduced its net metering cap from 5% to 2%, while Hawaii implemented a new “net energy metering plus” program that includes a monthly subscription fee. Other states, such as Arizona and New Mexico, have increased their net metering caps to accommodate rising solar adoption.
Storage and Demand Response
As the grid becomes increasingly reliant on intermittent renewable energy sources, storage requirements will become more critical. The US Department of Energy’s “Grid-Scale Energy Storage” report estimates that the US will need 50-100 GWh of energy storage by 2025 to meet peak demand. Demand response programs, which incentivize customers to adjust their energy usage in response to grid conditions, will also play a larger role in maintaining grid balance.
Next-Generation Net Metering
Future net metering policies will need to account for the integration of energy storage and other innovative technologies. The California Public Utilities Commission’s “Net Energy Metering 3.0” proposal, introduced in 2020, includes a new “demand charge” for solar customers and increased storage requirements for new installations. As the solar industry continues to evolve, regulators will need to adapt their policies to support the growth of renewable energy while maintaining grid reliability and profitability.
