In its latest survey of nonresidential sentiment, the score dropped to 43.5 from 56.9 from the previous quarter. Despite the deceleration, growth in 2025 is expected to remain strong across most nonresidential nonbuilding segments, driven primarily by water, wastewater and power infrastructure. They also see stability in segments such as healthcare, transportation, communication and highway/street construction. (FMIcorp.com, April 2025) • The Dodge Momentum Index (DMI) pulled back 6.9% to 205.6 (2000=100) in March from a revised February reading of 220.9, however the DMI is up 30% when compared to a year ago. The associate director of forecasts suggested the recent declines could be due to increased uncertainty around material prices and fiscal policies. The influence of data centers on the DMI remains substantial and overall activity remains higher than year-ago levels, suggesting steady activity into mid-2026.

11 MARKET OPPORTUNITIES FOR BOTH T&D AND C&I DATA CENTER MARKET EXPANSION. AI Driven Demand Increased Cloud Services Greater Data Storage Needs Deceleration of Power Efficiency Gains Crypto Mining Operations DATA CENTER DRIVERS DATA CENTERS DRIVING INCREMENTAL INFRASTRUCTURE INVESTMENT C Three’s 2024 North American Electric Transmission Market Forecast reports that AI is “supercharging” data center growth and is a major driver of increasing load growth projections. They noted that data centers are chasing cheap power for their locations, while hyperscale data center owners are also chasing renewable power. The report noted there are more than 170 hyperscale and co-location data centers planned, representing more than 45GW of capacity. (C Three, Sept. 2024) • A new report on U.S. data center energy usage found that data center electricity usage climbed from 58 TWh in 2014 to 176 TWh in 2023, and estimates usage will increase to 325-580 TWh by 2028. (energy.gov, December 2024) • To keep pace with the current rate of adoption, the power needs of data centers are expected to grow to about three times higher than current capacity by the end of the decade, going from between 3 and 4 percent of total US power demand today to between 11 and 12 percent in 2030. According to McKinsey analysis, the United States is expected to be the fastest-growing market for data centers, growing from 25 GW of demand in 2024 to more than 80 GW of demand in 2030. (mckinsey.com, September 2024) • According to a report from The U.S. Department of Energy’s (DOE), Lawrence Berkeley National Laboratory (LBNL), data center load growth has tripled over the past decade and continues to grow. LBNL expects data center electricity demand to grow to between 6.7 and 12% of total U.S. electricity by 2028. (newscenter.lbl.gov, January 2025) • According to The U.S. Department of Energy (DOE), data center deployment, partly driven by the need to power new AI applications, is a significant factor of near-term electricity demand growth. The Electric Power Research Institute (EPRI) estimates that data centers could grow to consume up to 9% of U.S. electricity generation annually by 2030, up from 4% of total load in 2023. (energy.gov, August 2024) MYR Group’s C&I division has decades of experience providing services for new construction, expansion build-outs, upgrades and maintenance of data center facilities. The T&D division has been providing utilities the construction services needed to support new electrical infrastructure for more than a century. Source: U.S. Department of Energy, August 2024

12 MARKET OPPORTUNITIES FOR BOTH T&D AND C&I CLEAN ENERGY GENERATION MIX. Federal Tax Credits Renewable Portfolio Standards Carbon Policy State Tax Incentives Clean Power Portfolios Customer Demand for Clean Power CLEAN ENERGY DRIVERS UTILITY-SCALE SOLAR INSTALLATIONS AND FORECAST SOURCE: SEIA/Wood Mackenzie Power & Renewables U.S. Solar Market Insight Report, 2024 Year in Review In 2024, the US solar industry installed nearly 50 gigawatts direct current (GWdc) of capacity, a 21% increase from 2023. The utility-scale segment installed a record-breaking 41.4 GWdc in 2024, 33% year-over-year growth and the second consecutive annual record. Developers installed more than 16 GWdc in Q4 alone. In the Base Case outlook, Wood Mackenzie forecasts that the utility-scale segment will add 356 GWdc of installed capacity between 2025 and 2035. Installation momentum from 2024 will continue into 2025, but installed capacity will start to plateau and decline starting in 2026 from a contraction in the overall pipeline. (seia.org, March 2025) The generation mix across the U.S. and Canada is changing as traditional baseload generation resources retire and clean energy provides an increasingly large percentage of demand. • Energy storage capacity installation rose 83 percent year-over-year in Q3 of 2024 and continued setting new milestones. With the addition of 3.5MW of capacity added during the quarter (the strongest third quarter on record), total U.S. installed energy storage capacity surpassed 25GW. (cleanpower.org, December 2024) • The Energy Information Administration reports that renewable energy generation is the main contributor to growth in U.S. electricity generation. The EIA expects solar generation to increase by 35 percent in 2025 and 18 percent in 2025, with additions of 31 GW in 2025 and 29 GW in 2026. (eia.gov, Short Term Energy Outlook, April 2025) • According to Wood Mackenzie, there is 83 GWh of installed energy storage capacity in the United States, including nearly 500,000 distributed storage installations. Current forecasts show that U.S. storage capacity is expected to reach 450 GWh by 2030, falling short of the capacity required to support our nation’s energy needs. (seia.org, January 2025)
