United States Power Market Analysis by Mordor Intelligence

The United States Power Market size in terms of installed base is expected to grow from 1.35 Thousand gigawatt in 2025 to 1.55 Thousand gigawatt by 2030, at a CAGR of 2.74% during the forecast period (2025-2030).

Thermal generation supplied 57.6% of capacity in 2024, yet the combination of Inflation Reduction Act (IRA) tax incentives and falling renewable costs is propelling utility-scale solar and wind through 2030. Coal retirements totaling 20 GW by 2030, tight transformer supply, and protracted transmission approvals are widening the reliability gap but simultaneously accelerating storage and demand-response deployments. Electric-vehicle load growth, heat-pump adoption, and hyperscale data-center procurement underpin a structural demand rebound after decades of flat consumption. Independent power producers (IPPs) are leveraging merchant price signals, while vertically integrated utilities channel record capital toward grid hardening to offset rising climate-related insurance premiums.[1]U.S. Energy Information Administration, “Electric Power Monthly,” eia.gov

Key Report Takeaways

  • By power source, renewables secured 57.6% of the United States power market share in 2024 and will expand at a 7.8% CAGR to 2030, outpacing every other source.
  • By end user, utilities commanded 64.9% of the United States power market size in 2024, whereas the residential segment is on track for a 10.4% CAGR through 2030 on distributed-solar adoption.
  • NextEra Energy, Vistra, and Constellation Energy collectively controlled more than 60 GW of renewable and storage assets in 2024, the largest combined portfolio among U.S. IPPs.

Segment Analysis

By Power Source: Renewables Accelerate as Thermal Dominance Erodes

Renewables captured 42.4% of installed capacity in 2024 and are advancing at a 7.8% CAGR, steadily eroding thermal’s majority position in the United States power market. Utility-scale solar additions of 32 GW in 2024 outpaced every other technology for the third straight year, while the 800 MW Vineyard Wind 1 project heralded commercial offshore wind entry. Coal retirements removed 8 GW in 2024, pushing average fleet capacity factors below 40% and increasing reliance on flexible gas assets for ramping. Nuclear capacity remains steady near 95 GW; the planned 835 MW restart of Three Mile Island in 2028 marks the first reactor return from retirement and underscores nuclear’s role in firm zero-carbon supply. Emerging geothermal projects such as Fervo’s 400 MW Project Red illustrate growing investor appetite for dispatchable renewables.[4]Fervo Energy, “Project Red Geothermal PPA,” fervoenergy.com

Investment momentum favors technologies with clear IRA incentives, positioning solar-plus-storage and wind as the default replacements for retiring fossil units within the United States power market. Developers nonetheless face interconnection delays, transformer shortages, and tariff exposure that add price volatility. Natural-gas combined-cycle builds are slowing as potential methane fees loom, yet existing gas fleets continue to capture scarcity rents during evening peaks. Small modular reactors earned Nuclear Regulatory Commission design approval in 2024, but commercial operation remains a post-2030 prospect. Biomass and tidal remain niche as environmental compliance costs outweigh revenue streams.

By End User: Residential Surge Challenges Utility Dominance

Utilities owned 64.9% of capacity in 2024, cementing their central role in the United States power market. Capital is flowing toward grid-hardening rather than new generation, reflecting regulatory incentives and climate-resilience mandates. The commercial and industrial segment, especially data centers, increasingly bypasses traditional procurement via direct PPAs and behind-the-meter builds, siphoning high-margin load from utilities. Amazon’s 960 MW data-center campus co-located with a Pennsylvania nuclear plant exemplifies cost-avoidance strategies by large buyers. 

Residential capacity is the fastest-growing slice of the United States power market, slated for a 10.4% CAGR to 2030 on rooftop-solar and home-battery diffusion. Installed residential solar surpassed 30 GW in 2024, and battery attachment rates in California exceeded 85% after NEM 3.0 cut export credits. The 30% residential ITC lowers payback periods to roughly seven years even in moderate-price states. Virtual power plants aggregating household systems delivered 500 MW of dispatchable capacity in 2024, opening new revenue for prosumers and distribution utilities alike.

Geography Analysis

Texas added 12 GW of capacity in 2024, 85% solar and storage, leveraging ERCOT’s merchant market and fast interconnection, yet weather resilience remains a headline risk after Winter Storm Uri. California led residential solar with 4.5 GW of installs in 2024 despite reduced export rates, and its 100% clean-energy mandate is pushing procurement of long-duration storage and out-of-state wind.[5]California Energy Commission, “Quarterly Solar Statistics,” cec.ca.gov Offshore wind entered commercial scale on the Atlantic coast, while lease awards totaling 25 GW off California in 2024 set the stage for floating-platform deployment.

Wind-rich Midwest states enjoy low land costs; Iowa generated 62% of its electricity from wind in 2024 and continues to add storage to maximize IRA energy-community credits. The Southeast trails on renewables due to vertically integrated utility structures, though Florida commissioned 3 GW of solar in 2024, citing hurricane-hardening benefits. The Northeast’s land constraints channel investment offshore; New York and Massachusetts contracted 9 GW of capacity, with the first electricity delivery expected in 2025.

Regional transmission organizations are converging markets to smooth renewable variability. PJM’s 2024 seasonal-capacity auction raised prices tenfold, incentivizing firm capacity but elevating consumer costs. MISO’s USD 10.3 billion multi-value project portfolio, approved in 2024, will connect Dakota wind to the Midwestern load. The Western Energy Imbalance Market grew to cover 80% of Western load, trimming curtailment by 1.2 million MWh in 2024. Integration trends foster arbitrage for storage and flexible gas, while narrowing locational spreads compress renewable merchant margins.

Competitive Landscape

The United States power market shows moderate concentration: the ten largest owners hold roughly 35% of capacity, and competitive pressure intensifies with IPPs and technology firms scaling renewable pipelines. Vertically integrated utilities in regulated states earn allowed returns on equity but face scrutiny over cost recovery for wildfire hardening and offshore wind ambitions. Deregulated regions reward fleet flexibility; Vistra’s ERCOT gas units captured USD 1.2 billion of gross margin during summer peaks despite low annual utilization.

Strategic differentiation pivots on asset mix, contracting model, and regulatory leverage. NextEra Energy’s 30 GW renewables portfolio enables bundled energy and capacity sales to both utilities and corporates, while its Florida Power & Light arm deploys 1.5 GW of solar annually to meet state load growth. Constellation monetizes its nuclear fleet through 24/7 zero-carbon contracts, attracting hyperscalers willing to pay 10%-15% premiums over conventional renewable credits. Pattern Energy illustrates a transmission-as-a-service model with its USD 10 billion SunZia HVDC and 3.5 GW wind combo, earning regulated returns while capturing development upside.

White space remains in mid-duration storage where lithium-ion economics weaken beyond four hours. Flow batteries, compressed-air storage, and geothermal reservoirs vie for scale but face financing hurdles without proven cost curves. Transmission developers offering standalone infrastructure investment also expand competitive boundaries as utilities prioritize core grid assets over generation ownership within the United States power market.
