2. Data Center Power Consumption: Current State

U.S. data center electricity consumption has accelerated sharply over the past decade, breaking a prolonged period of relative efficiency gains that had kept growth flat. The combination of cloud computing expansion and, more recently, AI infrastructure has driven consumption to levels that are reshaping national energy planning.

176 TWh — Total U.S. data center electricity consumption in 2023, up from 58 TWh in 2014. Compound annual growth rate of approximately 7% from 2014–2018, accelerating to 18% between 2018–2023. (DOE announcement | LBNL full report PDF)

3. Projected Power Demand Through 2030

No area of energy forecasting is moving faster than data center demand. Multiple Tier 1 sources — the DOE, IEA, and S&P Global — project demand to roughly double or triple from current levels by the end of the decade, with AI infrastructure identified as the primary driver in every major forecast.

325–580 TWh by 2028 — DOE/LBNL range for U.S. data center electricity consumption, representing 6.7% to 12% of total U.S. electricity. The wide range reflects uncertainty around AI adoption rates and chip efficiency improvements. (LBNL Report PDF)

4. Construction Spending & Capital Investment

The scale of capital being committed to data center infrastructure is without precedent in modern commercial real estate. Hyperscalers, institutional investors, and sovereign funds are all competing for the same constrained set of power-ready sites, driving both record construction activity and rising costs at every level of the supply chain.

$3 trillion in total investment projected over the next five years through 2030 — including approximately $1.2 trillion in real estate asset value creation and roughly $870 billion in new debt financing. JLL describes this as "the largest infrastructure investment supercycle in modern history." (JLL Newsroom | JLL 2026 Global Outlook)

5. Electrical Infrastructure Costs & Benchmarks

For electrical contractors, switchgear manufacturers, and transformer suppliers, the cost benchmarks below define the opportunity landscape. Power infrastructure — including switchgear, transformers, medium-voltage cable, UPS systems, and grid interconnection — typically represents 40–50% of total data center construction cost, making it by far the largest single cost category in any new build.

$10.7 million per MW — Average global data center construction cost in 2025, up from $7.7 million per MW in 2020 (7% CAGR over five years). (JLL 2026 Global Data Center Outlook)
$11.3 million per MW — JLL's forecast for average global construction cost in 2026 (6% year-over-year increase). Note: these are shell-and-core figures only; AI tenant fit-out can add as much as $25M/MW on top. (JLL 2026 Global Data Center Outlook)

6. Regional Hotspots: Where Data Centers Are Being Built

Data center geography is being reshaped by one variable above all others: power access. Traditional markets — Northern Virginia, Silicon Valley, Dallas, Chicago — are increasingly saturated, pushing development into secondary and tertiary markets wherever grid capacity exists.

Virginia consumes more than 25% of its total state electricity in data centers. Northern Virginia alone hosts roughly 13% of all global data center operational capacity and 25% of all capacity in the Americas. (Environment Virginia | Bay Journal, citing JLARC | JLARC Study PDF)

7. Grid Strain & Utility Challenges

The pace of data center load growth is outrunning the ability of the grid to respond. Interconnection queues, aging transmission infrastructure, and constrained supply chains for electrical equipment are creating cascading delays — and placing upward pressure on electricity rates for residential customers across the country.

Commercial sector electricity up 5% in 2026 — EIA projects this as the primary driver of record-high U.S. electricity demand in both 2025 and 2026 — the first time demand has risen four consecutive years since 2007. (Data Center Dynamics, citing EIA STEO | EIA Press Release, January 2026)
Wholesale power prices could rise as much as 50% — Dallas Fed estimate, with data center demand expected to double in the next five years. Inflationary effect projected at 0.04–0.13 percentage points added to annual PCE inflation by 2030. (Dallas Fed, March 2026)

8. The AI Factor: How Artificial Intelligence Is Driving Power Demand

Every major forecast identifies artificial intelligence as the primary driver of data center power demand growth through 2030. The shift is structural, not cyclical: AI training and inference workloads require fundamentally different — and far more power-intensive — infrastructure than traditional cloud computing, affecting everything from rack density and cooling design to substation sizing and grid interconnection.

AI is "the most important driver" of data center electricity demand growth globally, per the IEA. Global data center consumption is on course to more than double between 2024 and 2030. (IEA Energy and AI Executive Summary)
AI = 25% of data center capacity in 2025 → 50% by 2030 — JLL projects AI's share of all data center workloads to double in five years. (JLL 2026 Global Outlook)
AI could account for 35–50% of total data center power by 2030, up from 5–15% in recent years. (Carbon Brief, citing IEA)

Inference to overtake training as dominant AI requirement in 2027 — Unlike training (a periodic investment), inference generates ongoing, growing electricity demand as AI applications scale to end users, with geographic distribution requirements driving new regional deployments. (JLL 2026 Global Outlook)
By 2030, U.S. data centers will consume more electricity than all energy-intensive manufacturing combined — including aluminum, steel, cement, and chemicals production. (IEA press release, April 2025)
