SpaceX and Tesla Plan Massive US Solar Manufacturing Push as AI Demand Strains Grid
Published · 4 min read
Elon Musk announced at the World Economic Forum in Davos that both SpaceX and Tesla are independently working to build 100 gigawatts of solar manufacturing capacity per year in the United States. The combined 200 GW production could begin ramping up over the next three years.
To put this in perspective, the entire United States had only about 60 GW of solar module manufacturing capacity as of December 2025. The plan would more than triple current US solar production capabilities.
Why the Rush for Solar Power
The timing reflects a critical challenge facing the country’s electricity grid. US electricity demand is surging 24% beyond previous forecasts according to grid reliability authorities, with much of the growth driven by artificial intelligence data centers.
Current projections show US electricity consumption could grow up to 25% by 2030, with over half of this growth coming from data centers alone. Power demand from AI facilities could grow more than thirtyfold by 2035, reaching 123 gigawatts up from just 4 gigawatts in 2024.
Musk warned that “we’re very soon going to be producing more chips than we can turn on” because electricity supply, not computing power, has become the limiting factor for AI expansion.
The Grid Integration Problem
Simply flooding the market with solar panels won’t solve the energy crisis without addressing how to manage the power. The industry faces what’s known as the “duck curve” problem.
Solar generation peaks during midday when electricity demand is moderate, but disappears just as demand surges in the evening. This creates a sharp ramp where conventional power plants must rapidly increase output to fill the gap.
In California, the evening ramp requires up to 17,000 MW of generation to come online in just three hours. Similar patterns are emerging in Texas, Arizona, and Nevada.
Storage Projects Surge in Response
Battery storage installations are accelerating to address the mismatch between solar production and electricity demand. More than 10 gigawatts of utility-scale battery storage were installed nationwide in 2024.
Forecasts indicate approximately 18 gigawatts of new utility-scale battery storage capacity will come online by the end of 2025. This represents the largest annual buildout on record.
California continues to lead storage deployment, but Texas, Arizona, Nevada, and the Northeast are rapidly following. These states now treat energy storage as core generation infrastructure rather than an optional add-on.
Transmission Delays Threaten Timeline
Even with sufficient solar manufacturing and storage, transmission constraints could undermine the expansion. Experts warn that resolving interconnection bottlenecks and expanding transmission lines remains critical for timely deployment.
The situation is particularly urgent in regions experiencing explosive data center growth. In the PJM Interconnection region covering much of the Midwest and Mid-Atlantic, rising demand could lead to serious reliability challenges.
Without timely deployment of new clean energy resources, ratepayers in nine PJM states could pay an extra $360 billion over the next ten years. For the average residential household, this translates to $3,000 to $8,500 in additional electricity costs.
The AI Connection
The solar push appears directly linked to artificial intelligence expansion. Deloitte estimates that power demand from AI data centers could reach 123 gigawatts by 2035, up from 4 gigawatts in 2024.
The company has even filed with the Federal Communications Commission to launch up to 1 million solar-powered satellites that would serve as orbital data centers for artificial intelligence. Operating between 500 and 2,000 kilometers altitude, these satellites would maximize time in sunlight for solar power generation.
“By directly harnessing near-constant solar power with little operating or maintenance cost, these satellites will achieve transformative cost and energy efficiency,” the filing stated.
What Comes Next
The three-year timeline Musk outlined aligns with accelerating renewable deployment nationwide. The International Energy Agency projects US renewable capacity will increase 65% from 2021 to 2026, adding more than 200 GW of emissions-free generation.
Solar and wind are forecast to account for 99.2% of net new US capacity in 2026, with solar leading utility-scale renewable energy output. Utility-scale solar now represents nearly 12% of the nation’s total electrical generating capacity.
Success will depend on coordinated efforts in transmission expansion, energy storage deployment, and market design innovations. The alternative is a bottleneck that could limit AI development and drive up electricity costs for millions of Americans.
For consumers, the outcome could mean a more resilient electricity system with cleaner energy sources. But the road ahead requires solving complex grid management challenges on an accelerated timeline as both energy demand and renewable capacity reach unprecedented levels.
