Proper investment in grid upgrades is essential for managing increased bi-directional energy flows resulting from storage. The traditional grid infrastructure may not fully support the integration of distributed energy resources, including residential and commercial energy storage setups.
Unless you are planning to raise tens of millions of dollars to build a power plant and register with the electric grid, you cannot sell energy. You can, however, receive credits for excess power generated by your solar system.
For example, it is easier in some regions than in others for distributed storage to sell services into regional wholesale energy markets (and in non-ISO/RTO areas, wholesale energy markets may not even exist).
Battery energy storage systems are rechargeable batteries that store generated energy either from a generation source or the grid itself. They are "reversible" as resources to the grid, meaning that they can both dispatch and store energy, in bulk.
Energy storage resources have become an increasingly important component of the energy mix as traditional fossil fuel baseload energy resources transition to renewable energy sources. Currently 23 states, plus the District of Columbia and Puerto Rico, have 100% clean energy goals in place.

Energy storage technologies present a way for a state like Hawaii to continue transitioning to renewable energy while meeting peak demands for electricity. For example, the Kapolei Energy Storage project, a 185 MW battery facility, is scheduled to open on the island of Oahu in early 2023.
The DOE energy supply chain strategy report summarizes the key elements of the energy supply chain as well as the strategies the U.S. Government is starting to employ to address them. Additionally, it describes recommendations for Congressional action.
Energy storage technologies present a way for a state like Hawaii to continue transitioning to renewable energy while meeting peak demands for electricity. For example, the Kapolei Energy Storage project, a
When placed behind a customer meter, energy storage can effectively reduce or shift peak demand in two ways: first, by serving the customer''s load, which reduces their demand on the grid; or second, by exporting stored power onto the grid.
A policy primer exploring how energy storage technologies work, the benefits that storage can deliver to the electric grid, the current legal and regulatory barriers to adoption, and policy options for addressing those obstacles.
Energy storage resources have become an increasingly important component of the energy mix as traditional fossil fuel baseload energy resources transition to renewable energy sources. Currently 23 states, plus the
This primer is designed to assist state lawmakers in understanding how energy storage technologies work, the benefits that storage can deliver to the electric grid, the current legal and regulatory barriers to adoption, and policy options for addressing those obstacles.
While decisions carried out by federal regulators and regional market operators have an impact on state energy storage policy, state policymakers—and state legislators in particular—are instrumental in enacting policies that remove barriers to adoption and encourage investment in storage technologies.
In summary, selling energy back to the grid can be complicated and expensive. However, there are other options available to commercial and residential consumers that are looking to reduce energy costs. Our team understands the electricity grids in the U.S. and can help you navigate selling energy back to the grid.
States are also developing expert task forces and committees to evaluate storage technologies and opportunities for growth. Maine, for example, enacted HB 1166 (2019) creating a commission to study the benefits of energy storage in the state’s electric industry.
Although many people with solar systems on their homes or businesses think that they can sell excess electricity to the power grid, the reality is that you can only sell power to the grid if you have an electricity generator’s license and qualified power-generating assets.
To create a regulatory environment that supports energy storage as a distributed energy resource, legislatures have also focused on interconnection requirements and ensuring that distributed resources can connect to the grid in a timely and efficient manner.
With widespread grid failures on this scale, energy storage would have to make up a much larger share of system capacity than it currently does to change the dynamics, although it can respond to sudden system fluctuations by providing ancillary services, like frequency and voltage regulation.
