Battery Storage Hits 16% of New Utility-Scale Solar Capacity in 2026

According to newly released data from the U.S. Energy Information Administration (EIA), small business owners may have a growing opportunity to leverage a powerful combination of solar energy and battery storage. As utility-scale solar development continues to evolve, the integration of battery storage with solar capacity is becoming increasingly popular. As of September 2026, over 16% of new utility-scale solar capacity added this year is accompanied by operable battery storage, a significant leap from just 2% in 2017. This upward trend illustrates a market shift that could greatly benefit small businesses looking to reduce energy costs and increase efficiency.

The concept of co-locating battery storage with solar photovoltaic systems enables businesses to optimize their energy output. In areas where solar energy production is high, electricity prices tend to dip. Conversely, prices rise when solar contributions decline. By using battery storage in conjunction with solar systems, businesses can manage when to send power to the grid or store it for later use. This flexibility can help optimize energy usage based on fluctuating wholesale prices, allowing businesses to take advantage of lower rates when available.

As the data suggests, this approach is already being adopted on a wide scale. With reported plans indicating the share of solar capacity that includes battery storage could climb to 19% by the end of the year, and with projections exceeding 30% in plans for 2027 and 2028, now is the time for small business owners to contemplate making the switch.

“Plants with both solar and battery storage can manage the combined output of their generating resources to maximize their value in a changing wholesale price environment,” emphasized the EIA. This adaptability can make small businesses more resilient and financially stable, particularly in an era marked by variable energy costs.

Regions like California, Arizona, New Mexico, and Nevada are already seeing the advantages, as these southwestern states boast higher-than-average shares of solar capacity relative to total generating capacity. Eighteen percent of utility-scale solar capacity in these areas is co-located with battery storage, which is more than double the national average. For small business owners in these regions, the benefits are clear: the increased reliability and cost-effectiveness associated with integrating solar and battery systems can directly impact their bottom line.

Moreover, EIA’s monthly and annual data collections track the development of these technologies, providing small businesses with valuable insights and the necessary information to make data-driven decisions. The ability to anticipate trends in energy generation can help business owners not only prepare for future energy costs but also align their operations with eco-friendly practices, tapping into the growing market demand for sustainable entrepreneurship.

However, the transition to co-located energy systems may not come without its challenges. Small business owners may face various barriers, including the initial installation costs, which could be significant depending on the scale of the solar and battery systems they’re looking to install. Managing the integration process with existing energy infrastructure could also pose logistical challenges. Additionally, the fluctuating regulations and incentives for renewable energy projects can impact the feasibility and long-term benefits of such investments.

Understanding the available financing options, potential tax incentives, and utility programs can help mitigate these concerns. Small business owners should conduct thorough research and, if possible, consult with energy specialists to fully comprehend the dynamics of integrating solar and battery storage into their operations.

The growing incorporation of co-located solar and battery storage systems signifies a transformative movement in the energy landscape, offering small businesses enhanced energy resilience and competitive advantage. For those ready to embrace the shift, substantial rewards may be on the horizon.
