Mythbusting
Battery energy storage systems (BESS) store energy and distribute the energy to the electric grid, homes, or businesses. When paired with solar, the duo provides the most reliable and affordable sources of power generation we can deploy right now.

SEIA IMpACT
Policy Advocacy
Our team is advocating for critical laws and forward-thinking policies that are shaping the future of energy storage and securing a more resilient, reliable, and sustainable energy system for communities nationwide.
ILLINOIS
SEIA led a broad coalition to pass a 3,000 MW procurement for Battery Energy Storage Systems (BESS). This legislation will break open new markets for grid-scale, distributed, and behind-the-meter energy storage while saving Illinois customers an estimated $13 billion over 20 years.
NATIONAL
SEIA’s congressional team kicked into overdrive in 2025 and saved the investment tax credits for BESS, ensuring policy certainty and financial security for most projects.
COLORADO
SEIA secured a major victory with the state’s Public Utility Commission with the adoption of a Virtual Power Plant program and flexible interconnection tariff requirements, which will create major market opportunities for energy storage.
Policy Priorities
With boots on the ground in roughly 15 states and a deep bench of experts advocating for our industry in Congress and at the federal agencies, SEIA is fighting to open markets for energy storage across the country.
Defend and implement federal BESS policies
-
SEIA advocates for reasonable and attainable Foreign Entities of Concern (FEOC) guidance and Treasury Department rules.
-
SEIA is actively fighting to protect federal programs in the Executive Branch that promote storage development.
-
Finally, SEIA is working to preserve the supply and affordability of BESS products as supply chains onshore and decouple themselves from FEOC countries.
Launch and implement state-level programs to financially support energy storage
In states across the country, SEIA is leading legislative and regulatory efforts to ensure that utilities open paid programs for grid-scale and distributed BESS, both front-of and behind-the-meter.
Secure fair access to markets
SEIA fights for fair valuation of energy storage in forward capacity markets (Effective Load Carrying Capacity – “ELCC”) for grid-scale and distributed BESS.
Reduce interconnection costs
-
SEIA advocates for flexible interconnection tariffs so BESS can get on the grid faster and more affordably.
-
SEIA is continuing our steadfast support for surplus interconnection service at regional transmission organizations (RTOs) and independent system operators (ISOs).
Secure favorable retail rates for distribution BESS
Lower barriers to siting
- SEIA is working to keep cities and counties “open for business” for BESS, leading to lower bills and higher reliability.
- SEIA policy experts are diligently crafting and promoting bills that streamline BESS siting while opposing and defeating bills with onerous siting requirements.
- In conjunction with our state affairs and codes & standards team, SEIA experts are guiding state officials in setting evidence-based standards for siting and fire protection.
- In a time of regulatory uncertainty, we are continuing to push Federal agencies to issue permits in accordance with laws and reasonable regulations.
Codes and Standards
The deployment of energy storage is heavily impacted by building, electrical, and fire codes. In forums across the country, SEIA has experts advocating for reasonable, consistent, and evidence-based codes and standards that maintain the highest levels of safety without inflating the costs to build.
Regional Consistency
Clear Guidance
SEIA is focusing on improving permitting and siting guidance for BESS to enable safe, scalable, long-term deployment of residential, small-scale commercial, and large-scale BESS systems. SEIA supports simplifying the International Residential Code.

Critical Minerals
Energy storage requires diverse, abundant, and affordable material inputs. We are advocating for business growth across all vectors of the storage component value chain to address limited access to financing, dependence on foreign supply chains, and the midstream refining and processing gap.
In 2026, SEIA is prioritizing the onshoring of critical mineral and battery supply chains in the U.S. and allied countries. We are advocating for the development of balanced policy solutions that align domestic industrial growth, competitiveness, and national security.
