Net metering is a policy that allows utility customers to generate their own electricity cleanly and efficiently using solar panels or wind turbines and either use it to offset their energy consumption or sell the excess back to the grid. While net metering is not mandatory for all electric companies in the United States, 44 states and Washington, D.C. have developed mandatory net metering rules for at least some utilities as of March 2015. Additionally, three states (Alabama, South Dakota, and Tennessee) offer no form of net metering or compensation. Net metering has been a controversial topic, with some utilities viewing it as a lost revenue opportunity and a subsidy, while others see it as a way to promote the adoption of renewable energy sources and create jobs in the solar industry.
Is it mandatory for electric companies to offer net metering?
| Characteristics | Values |
|---|---|
| What is net metering? | A policy by many states in the United States designed to help the adoption of renewable energy. |
| Who does it apply to? | Residential and commercial customers who generate their own electricity from solar power or wind turbines. |
| How does it work? | Customers are billed for their "net" energy consumption, i.e., the total electricity consumed minus the total electricity generated. If their net consumption is positive, they pay an electricity bill. If it is negative, they receive a credit for the excess electricity generated. |
| Where is it available? | As of March 2015, 44 states, Washington, D.C., and Puerto Rico have mandatory net metering rules for at least some utilities. However, the specific policies and compensation rates vary by state and utility company. |
| What are the benefits? | Net metering encourages the adoption of renewable energy sources, reduces strain on distribution systems, and provides economic benefits in terms of jobs and investments in the solar industry. |
| What are the concerns? | Utility companies argue that net metering results in lost revenue as they have to purchase electricity from customers at retail rates when they could get it more cheaply from wholesale markets. It also leads to higher rates for non-net metering customers. |
| Are there any alternatives? | Some states have proposed charging net metering customers their "otherwise applicable rate" for electricity used from the grid, with a fixed export compensation rate for exported energy. |
| What about on a smaller scale? | Net metering is also available for homeowners with solar panels, allowing them to send excess energy generated during the day back to the grid and offset their energy use at night. |

Net metering is a billing mechanism that credits solar energy system owners for electricity added to the grid
Net metering is a billing mechanism that allows utility customers to generate their own electricity cleanly and efficiently through solar power. During the day, most solar customers produce more electricity than they consume. Net metering allows them to export excess power to the grid and receive credits for the electricity they add to the grid, reducing their future electric bills.
Net metering policies create a smoother demand curve for electricity and allow utilities to better manage their peak electricity loads. Net metering also encourages the generation of electricity near the point of consumption, reducing strain on distribution systems and preventing losses in long-distance electricity transmission.
Customers who net meter are billed for their net consumption of electricity. If their net consumption is positive, they must pay an electricity bill to their electric company for the excess consumption at the end of the billing period. If their net consumption is negative, they will receive a net metering credit on their electricity bill and will not owe the electric company money during that billing period. These net metering credits never expire and will roll over to the next billing period unless the facility is a cap-exempt facility serving on-site load.
Net metering programs differ in how long credits are allowed to roll over and how much value each credit has. Some net metering programs provide a monetary bill credit that can be equal to the retail value of a kilowatt-hour (kWh), but sometimes it can be less. For example, under Net Energy Metering (NEM) 2.0 in California, the energy credits are worth slightly less than the retail rate due to non-bypassable charges that fund low-income and environmental programs.
As of 2024, 34 states plus Washington, D.C., and Puerto Rico have mandatory net metering rules in place. However, some states are starting to move away from net metering as the economics of participating in the grid become increasingly complicated.

Net metering increases demand for solar energy, creating jobs in the solar supply chain
Net metering is a billing mechanism that credits solar energy system owners for the electricity they add to the grid. It allows residential and commercial customers who generate their own electricity from solar power to sell the electricity they don't use back into the grid. Net metering policies have a direct impact on the solar industry and its job market.
Net metering increases demand for solar energy, which in turn creates jobs in the solar supply chain. The solar industry currently employs over 230,000 Americans, largely due to strong state net metering policies. The demand for solar energy creates jobs for installers, electricians, and manufacturers. Net metering also encourages new solar development on existing structures, which reduces carbon emissions and the need for new power transmission infrastructure.
Net metering policies also create a smoother demand curve for electricity, allowing utilities to better manage their peak electricity loads. This can reduce the strain on distribution systems and prevent losses in long-distance electricity transmission and distribution. Net metering can also reduce the financial costs for homeowners, as they can design a solar system that won't exceed their total usage in sunny months.
However, some argue that net metering represents a "cost shift" from wealthier to lower-income people, as those who can afford solar panels can significantly reduce their energy bills, leaving those without solar to pay a larger share of the fixed costs of maintaining the grid. Additionally, as the number of net-metered solar installations increases, the distribution grid may need to be upgraded to handle higher levels of two-way power flow, which can increase costs for ratepayers.
While net metering has been mandatory in 34 states, Washington, D.C., and Puerto Rico, some states are starting to move away from it due to the complex economics of participating in the grid. Nonetheless, net metering has played a significant role in increasing the demand for solar energy and creating jobs in the solar supply chain.

Some utilities view net metering as a subsidy, paying retail rates for power from solar panels
Net metering is a billing mechanism that allows utility customers to generate their own electricity cleanly and efficiently through solar power. During the day, most solar customers produce more electricity than they consume, and net metering allows them to export excess power to the grid and reduce their future electricity bills.
Net metering has been widely adopted in the United States, with 34 states, Washington, D.C., and Puerto Rico having mandatory net metering rules in place. Additionally, as of 2013, 43 US states had adopted net metering, along with utilities in 3 of the remaining states, leaving only 4 states without any established procedures for implementing net metering.
However, some utilities view net metering as a lost revenue opportunity or a subsidy. They argue that net metering policies shift costs onto non-net metering customers, who end up paying more to subsidize net metering customers. This perception is supported by studies such as the one conducted by Energy+Environmental Economics (E3) for the California Public Utilities Commission (CPUC) in 2013. The E3 study estimated that net metering would result in a cost shift of $1.1 billion annually by 2020 from net metering to non-net metering customers in California.
On the other hand, proponents of net metering argue that it provides substantial economic benefits, including job creation in the solar industry, income, and investment. Additionally, net metering reduces strain on distribution systems and prevents losses in long-distance electricity transmission and distribution.
While the debate surrounding net metering continues, it is important to note that net metering customers are still billed for their "net" energy use, and the excess power they generate can be credited towards future electricity consumption or, in some cases, refunded.

Net metering policies can vary significantly by country, state, or province
Net metering policies can vary significantly from one country, state, or province to another. These policies can include whether net metering is available, the duration of banked credits retention, and the value of these credits. Most net metering laws involve a monthly rollover of kWh credits, a small monthly connection fee, a monthly payment of deficits, and an annual settlement of any residual credit.
Net metering originated in the United States, where consumers with small wind turbines and solar panels connected to the electrical grid wanted to use the electricity generated at a different time or date. As of 2013, 43 US states have adopted net metering, with utilities in 3 of the remaining states offering net metering, leaving only 4 states without any established procedures for implementing net metering. However, a 2017 study showed that only 3% of US utilities offer full retail compensation for net metering, with the rest offering less than retail rates, having credits expire annually, or providing indefinite rollover. Some states, like Indiana, have phased out net metering, while others, like Illinois, have removed caps on net metering.
In Canada, some provinces have net metering programs, while in India, almost every state has implemented net metering, but the policy is not common throughout the country and varies from state to state. An application process is required for consumers to avail of net metering in India. In Europe, Slovenia has had annual net metering since 2016, while Spain and France have proposed or are considering net metering.

Frequently asked questions
Net metering is a billing mechanism that allows customers who generate electricity through solar power to sell their unused electricity back into the grid.
As of 2015, 44 states and Washington, D.C., have developed mandatory net metering rules for at least some utilities. However, the implementation and compensation rates vary across states and utilities.
No, net metering is not available in all states. For example, Alabama, South Dakota, and Tennessee do not offer net metering or compensation.
Net metering encourages the adoption of renewable energy sources, such as solar and wind power. It also provides economic benefits, including job creation in the solar industry and reduced electricity bills for participating customers.
Electric companies may view net metering as a lost revenue opportunity, as they are required to purchase electricity from customers at retail rates, while they could obtain wholesale power at lower prices. Additionally, as more customers adopt net metering, the contribution to fixed utility costs decreases, potentially leading to higher rates for non-net metering customers.
