2025 represents a pivotal stage in the United States’ transition toward a clean energy future. By implementing a dynamic, forward-thinking strategy, engineering, procurement, and construction (EPC) firms and project developers stand to benefit from both near-term growth and the substantial upside of the rapidly evolving market.

Let’s examine the trends likely to shape the utility-scale solar sector in 2025 and consider how developers and EPCs can take their solar projects to the next level.

Current Utility-Scale Solar Snapshot

Through the first nine months of 2024, solar, led by the utility-scale sector, was the only primary source of generation that recorded capacity growth, jumping 88% to 18.6 gigawatts (GW). As a result, solar surpassed hydropower and nuclear as the fourth-largest source of installed capacity after wind. Battery storage accounted for the second-largest share of total generating capacity additions, rising by 64% to 7.4 GW. By the end of 2025, the US Energy Information Administration (EIA) expects solar to rise by a record-breaking 38.4 GW to 128.2 GW, with battery storage increasing by another record-breaking 14.9 GW to 30.9 GW.

Federal Energy Policy Uncertainty

The big question on everyone’s mind is how the new administration will approach energy policy, particularly the continuity of the Inflation Reduction Act (IRA) and the Investment Tax Credits (ITC). Reports suggest that a complete repeal of the IRA is unlikely since federal agencies have already invested or committed nearly half of the $105 billion allocated for climate programs in grants, awards, and other direct spending.

Possible rollbacks or constrained budgets do remain on the table as the new administration takes shape; however, clean energy tax credits and tax equity are incredibly popular. The ITC, which the IRA cemented at 30% until the end of the decade, has been one of the most important factors contributing to the expansion of solar energy. Some experts believe the credit may not be abolished outright but could potentially be phased down sooner than the current 2030 expiration date, limiting the long-term outlook for large-scale procurement deals.

The Energy Demand Dilemma 

Despite potential headwinds posed by policy changes, utility-scale solar remains bolstered by surging electricity demand that’s not going away. After decades of minimal change, forecasts indicate electricity demand may increase by 9% by 2028 and 18% by 2033, with peak demand growing by 5% over the next four years.

Data centers represent a major slice of new load in states such as Texas, Georgia, and Virginia, often demanding hundreds of megawatts of power apiece. Between 2023 and 2028, data centers could account for 44% of the country’s electricity load growth.

Meanwhile, the electrification of buildings and vehicles has gained speed, driving up overall electricity consumption and spurring utilities to seek new clean energy sources. These demand pressures, combined with corporate sustainability goals, may help keep the IRA and ITC in place to keep pace with rising demand.

However, with interconnection queues stretching for years, it will be challenging to meet this surging demand in the near term.

Interconnection Bottlenecks and Transmission Congestion Persist

It’s a common refrain by now, but interconnection challenges will remain a barrier to rapid utility-scale solar deployment in 2025. Despite state-level and regional reforms intended to expedite the queue process, multi-year backlogs remain pervasive due to the complexity of multi-stakeholder reviews, environmental assessments, and inadequate and aging transmission lines. These delays directly impact commissioning schedules and project costs. Even once interconnected, projects may face potential curtailment because of congestion.

As more developers seek to capitalize on favorable incentives and accelerate new GW-scale builds, administering these projects on a strained grid becomes more challenging.

Solutions with energy battery storage integration can help ease congestion. However, these options often require sophisticated coordination with regional grid operators, financiers, suppliers, and pre-engineering design to bring the project to fruition.

Utility-Scale Solar Economic Trends, Storage Integration, and LCOE

These interconnection backlogs have created difficulty for prospective renewable energy buyers approaching deadlines for their clean energy goals, contributing to price increases. Although financing costs rose persistently through 2023 and 2024 due to broader macroeconomic pressures such as the federal interest rate and inflation, the levelized cost of electricity (LCOE) for utility-scale solar continues to decline in many regions, due to continued gains in module efficiency and polysilicon price declines. The pairing of solar with battery storage has also evolved beyond niche status to near-standard practice for new utility-scale proposals, especially where transmission constraints create peak pricing opportunities. Industry data shows that about 26% of utility-scale PV capacity in 2023 was already configured as a hybrid PV/battery energy storage system. This hybrid structure often fetches more favorable power purchase agreements (PPAs) by delivering dispatchable capacity during evening hours, improving project economics and resiliency.

Workforce Constraints and Community Relations

Labor constraints remain another pressing issue, especially in specialized electrical roles. The 2023 National Jobs Surveys, released in September 2024, indicated the solar workforce expanded by nearly 6% in 2023, but utility-scale solar accounted for about 75% of total megawatts installed—raising concerns that labor efficiency is pushing headcount growth at a slightly slower pace relative to project capacity. Recruiting and retaining skilled trades is becoming a strategic priority that influences whether projects meet their in-service dates. Developers and EPCs should consider apprenticeship programs and community-based workforce initiatives to improve labor logistics.

Local resistance over land use further complicates site selection for large solar plants. Delays can arise if communities perceive solar arrays as disruptive, potentially citing noise, aesthetic impacts, or environmental concerns. According to recent data, at least 31 states have installed 1 GW or more of solar. The growth also spreads the need for extensive stakeholder engagement across multiple states. Approaches that highlight co-location with agricultural operations, pollinator habitats, or other community benefits are proving to be valuable in smoothing out permitting processes.

Strategic Considerations for Utility-Scale Solar Developers and EPCs

1. Streamline Procurement: As project complexity increases, streamlining procurement from a one-stop shop will be a crucial differentiator for solar companies seeking new ways to lower soft costs, speed up installation times, optimize system performance, and lower LCOE. 

2. Labor Pipeline Initiatives: Utilize partner programs with access to educational and technical resources to help train workers and keep them updated on the latest technology, best practices, and safety standards.

3. Solar Plus Storage Solutions: Bundle energy storage capacity into solar proposals to target peak-hour revenues, improve dispatchability, and secure more robust PPAs. 

4. Community Engagement: Foster local acceptance with transparent communication, land-use flexibility, and collaboration on environmental stewardship or agricultural co-location.

5. Improve Efficiency and Enhance Reliability: With 720W power output and up to 23.2% efficiency, Trinasolar’s Vertex N boosts system generation. Vertex N was awarded as a “Top Performer” in all seven tests of the Kiwa PV Evolution Labs (Kiwa PVEL) 2024 PV Module Reliability Scorecard, a significantly rare and noteworthy feat.

Utility-scale solar developments in 2025 will be shaped by strong incentives, surging corporate and residential electricity demand, and the ongoing quest to manage transmission constraints effectively. While short-term hiccups like interconnection congestion could marginally slow near-term installations, the broader trajectory remains undeniably positive.
