Federal Energy Regulatory Commission
Declines to Regulate Net Metering
July 24, 2020
is a policy through which electricity customers with their own electricity generation systems
are compensated for the energy they produce (above what they consume). Typically, net metering
customers receive a bill credit for any excess electricity they produce over the course of a month. In other
words, their monthly electricity bills reflect the net
of electricity used from the grid and delivered to the
grid. Rooftop-mounted solar photovoltaic panels (i.e., rooftop solar) make up nearly all net metering
generation capacity in the United States. For simplicity, the following discussion refers to generators
participating in net metering as rooftop solar. Most states
have adopted a net metering policy.
The Federal Energy Regulatory Commission (FERC) regulates wholesale and interstate electricity
transactions, pursuant to the Federal Power Act (FPA).
The FPA defines wholesale electricity transactions
as “sale of electric energy to any person for resale.”
In 2001 (and again, in 2009), FERC determined that
net metering policies do not constitute a sale for resale.
Currently, states and local authorities regulate net
On April 14, 2020, the New England Ratepayers Association (NERA) filed a petition with FERC, as
the Commission to exert jurisdiction over most types of net metering transactions, arguing that they
constitute a sale for resale. NERA asked that FERC regulate rooftop solar in the same way it regulates other small-scale generators
pursuant to the Public Utility Regulatory Policies Act (PURPA; P.L. 95-617).
It argued, in part, that many state net metering policies require utilities to overcompensate rooftop solar
owners because net metering customers are compensated above the utility’s avoided cost. Further, NERA
argued that many state net metering policies inequitably shift costs to customers without rooftop solar. Some stakeholders
raised concerns that if FERC regulated net metering as NERA proposed, rooftop solar
would receive less compensation, potentially slowing its development.
On July 16, FERC unanimously dismissed the petition
on procedural grounds, leaving the status quo in
place. However, FERC left open the possibility that it might reconsider issues related to rooftop solar in
NERA’s petition raised interest in issues related to net metering, some of which are discussed below.

Federal Jurisdiction over Electricity
The FPA establishes a “bright line” between federal jurisdiction over wholesale transactions (e.g., sales
for resale) and state jurisdiction over retail transactions (e.g., sales to electricity consumers). Congress, in
PURPA and amendments thereto, has encouraged, but not required, states to adopt certain standards
regarding retail rates, electric utility operations, and other retail transactions. The Energy Policy Act of
2005 (EPACT05; P.L. 109-58)
amended PURPA to encourage states to adopt net metering.
have raised concerns that FERC regulation of net metering would cross the
jurisdictional bright line and infringe on regulatory authority historically reserved to the states.
Solar Energy Development
Congress has enacted a variety of policies to promote solar energy development since the 1970s, and the
appropriate federal role in promoting solar energy development remains a topic of debate. Development
of solar energy nationwide has increased, especially in recent years, reaching 2.6% of total electricity
generation in 2019
(including both utility- and small-scale generation).
The amount of solar energy generated within each state varies considerably. Variations in state net
metering policies are one driver of these differences, especially differences in small-scale solar energy
(e.g., rooftop solar). In most states, less than 1% of all electricity customers
net metering. Hawaii has the highest rate of net metering participation, at more than 15%, driven by
supportive state policies and its relatively high cost of electricity. Large-scale solar energy projects are
rarely eligible for net metering, so they are affected more strongly by other types of policies.
Energy burden is the share of household income spent on energy expenses. Net metering customers have
lower electricity bills than other customers because of the bill credits they receive. Thus, net metering has
been promoted as an option to reduce household energy burden. However, some analysis suggests
metering policies increase energy burden for non-net metering customers. Historically, low-income
households are under-represented among net metering customers, raising concerns that net metering is a
Electricity rates sometimes increase when the number of net metering customers
crosses a certain threshold because rates are designed to allow utilities to fully recover the costs of
operating the electricity system.
Utilities frequently argue that net metering customers do not pay their
share of utility costs, causing rates to rise and thus potentially increasing bills for other customers. NERA
also made this argument in its petition.
have modified their net metering policies in recent years, in some cases to address concerns
about how net metering affects energy burden for households without rooftop solar. Many of these
modifications include alternative compensation mechanisms (sometimes called Net Metering 2.0)
customers that own solar generation.
Considerations for Congress
Members of Congress could allow the FERC decision to stay without further action, effectively
preserving the status quo on net metering but leaving open the possibility that future FERC decisions
would address net metering and related issues. Alternatively, Congress could consider legislation to give
FERC policy direction regarding net metering—bills have been proposed in recent years
to either limit or
expand net metering—or the broader topic of distributed energy resources.
Congressional Research Service
Congress could also choose to consider other issues related to net metering. One such issue receiving
attention involves whether the longstanding jurisdictional bright line remains appropriate given recent
technology developments in electricity technologies, such as rooftop solar that can be directly connected
to homes and businesses. Congress could also choose to consider issues related to solar energy
development and energy burden in the context of state net metering policies and other industry trends.
