The U.S. power sector is undergoing a significant transformation as utilities, businesses, and policymakers work to meet rising electricity demand while supporting reliability and sustainability goals. Renewable energy has become an increasingly important part of this transition, with solar energy emerging as one of the fastest-growing sources of new electricity generation. At the same time, energy storage technologies are playing a larger role in helping integrate renewable resources into the grid and support system reliability.
Recent findings from Wood Mackenzie and the Solar Energy Industries Association (SEIA) highlight the scale of this shift. According to the U.S. Solar Market Insight Q2 2026 report, solar and storage accounted for 91% of all new U.S. power generation capacity added during the first quarter of 2026. Solar alone represented 60% of new capacity additions during the quarter. While installation volumes can fluctuate from quarter to quarter, the report reflects a broader trend that has been developing for years: solar and storage are becoming central components of the nation’s electricity infrastructure.
Solar energy has experienced remarkable growth across the United States over the past decade. Improvements in panel efficiency, declining technology costs, and growing demand for clean electricity have helped drive deployment across residential, commercial, and utility-scale markets.
Utility-scale solar projects continue to account for a large share of new capacity additions. Compared to many other generation technologies, solar facilities can often be developed and constructed relatively quickly, making them attractive options for utilities seeking to meet growing demand. In many regions, solar projects also offer competitive economics, helping utilities diversify their generation portfolios while managing long-term costs.
The Wood Mackenzie report found that the United States installed 7.8 gigawatts (GW) of solar capacity during the first quarter of 2026. Although this represented a decline compared to some previous quarters, solar remained the largest source of newly added generation capacity. The report also noted continued growth in utility-scale contracting activity, with contracts increasing by 15% year over year.
Several factors continue to support long-term solar growth:
As electricity demand continues to rise, solar is expected to remain an important option for adding new generation capacity in many regions of the country.
While solar often receives the most attention, energy storage has become one of the most important developments in the modern power sector. Battery storage systems allow electricity generated during periods of high renewable output to be stored and used later when demand increases or renewable generation declines.
This capability helps address one of the longstanding challenges associated with renewable energy. Solar generation is highest during daylight hours, while electricity demand often remains elevated during the evening. Storage systems help bridge this gap by shifting energy availability to periods when it is needed most.
Storage provides several benefits for grid operators and utilities, including:
As deployment increases, solar and storage are increasingly being developed as integrated projects. Utilities are finding that combining these technologies can improve operational flexibility while helping meet both energy and capacity needs.
The prominence of storage in the Wood Mackenzie report demonstrates how the market is evolving. The finding that solar and storage accounted for 91% of new power capacity additions reflects the growing importance of both technologies working together to support the grid.
Another important factor shaping the U.S. power sector is the rapid growth in electricity demand. After years of relatively stable electricity consumption, demand forecasts have increased significantly due to several emerging trends.
One major contributor is the expansion of data centers and artificial intelligence infrastructure. AI applications require substantial computing resources, leading technology companies to invest heavily in new data center capacity. These facilities consume large amounts of electricity and are expected to become increasingly important drivers of demand growth over the coming years.
At the same time, transportation, buildings, and industrial processes are becoming more electrified. Electric vehicles, electric heating technologies, and industrial electrification initiatives are increasing electricity consumption across many sectors of the economy.
Meeting this demand will require significant investment in generation, transmission, and grid infrastructure. Renewable energy projects are expected to play a major role because they can often be deployed more quickly than some conventional generation resources.
The Wood Mackenzie report noted continued growth in utility-scale solar contracting activity, suggesting that utilities and large energy buyers are actively planning for future electricity needs. This trend reflects a broader recognition that additional generation resources will be required to support economic growth, digital infrastructure expansion, and electrification initiatives.
The evolving power sector presents both opportunities and challenges for organizations seeking to manage energy costs and sustainability goals. As solar and storage become more prominent parts of the electricity system, businesses may encounter a changing landscape for energy procurement and emissions management.
Many organizations have established greenhouse gas reduction targets that include Scope 2 emissions associated with purchased electricity. The increasing availability of renewable energy can support these goals, but the broader energy market remains complex. Electricity demand growth, regional grid constraints, transmission limitations, and evolving market conditions can all influence energy procurement strategies.
Organizations may benefit from greater visibility into energy consumption patterns, emissions data, and renewable energy opportunities. Understanding how electricity is generated and delivered can help businesses make informed decisions about procurement, sustainability reporting, and long-term planning.
The growing role of storage may also influence future energy strategies. As storage deployment expands, businesses could gain access to new opportunities related to demand management, resilience planning, and renewable energy integration. These developments may become increasingly relevant as electricity systems continue to evolve.
The latest findings from Wood Mackenzie and SEIA provide a snapshot of an energy sector that is changing rapidly. Solar and storage accounted for 91% of new U.S. power capacity additions during the first quarter of 2026, highlighting the growing role these technologies play in supporting the nation’s electricity needs.
Several factors are contributing to this momentum, including rising electricity demand, continued renewable energy investment, advances in energy storage technology, and growing interest in reliable and sustainable energy resources. While challenges related to transmission, permitting, and grid infrastructure remain, solar and storage are expected to remain important components of future power system development.
For utilities, businesses, and sustainability leaders, understanding these trends will be increasingly important. The growth of solar and storage reflects broader changes occurring across the energy landscape, shaping how electricity is generated, delivered, and managed in the years ahead.
