Meta Inks Deal for Space-Beamed Solar Power to Fuel AI at Night

The escalating demand for electricity to power advanced AI models has propelled tech giants to explore innovative energy solutions. In a groundbreaking move, Meta has announced a significant agreement with the startup Overview Energy, aiming to harness solar power from space to energize its vast data centers during nighttime hours. This ambitious partnership could see a constellation of a thousand satellites beaming infrared light to terrestrial solar farms, marking a pivotal step in securing sustainable and continuous power for the future of artificial intelligence. Meta's energy consumption is colossal; its data centers alone consumed over 18,000 gigawatt-hours of electricity in 2024, an amount sufficient to power more than 1.7 million American homes for an entire year. With its need for compute power steadily increasing, Meta has committed to developing 30 gigawatts of renewable power sources, with a strong emphasis on industrial-scale solar power plants. Traditionally, relying on solar energy for data centers necessitates substantial investment in battery storage or a switch to alternative generation sources once the sun sets, posing a significant operational and financial challenge. Overview Energy, a four-year-old Virginia-based company that emerged from stealth last December, offers a novel approach to this dilemma. The company is actively developing specialized spacecraft designed to collect abundant solar power directly in space. This collected energy is then ingeniously converted into near-infrared light, which is subsequently beamed down to sufficiently large terrestrial solar farms, typically hundreds of megawatts in scale. These farms can then efficiently convert the received light into usable electricity, effectively extending their operational hours beyond daylight. A key differentiator for Overview's technology lies in its safety and regulatory strategy. By employing a wide, infrared beam to power existing ground-based solar infrastructure, the company aims to circumvent the complex technological, safety, and regulatory hurdles often associated with transmitting power to Earth via high-power lasers or microwave beams. Marc Berte, CEO of Overview, assures that their satellite's beam is harmless, allowing direct observation without adverse effects, which is crucial for public acceptance and widespread deployment. The potential benefits of this technology are substantial, including an improved return on investment for solar farms and a reduced reliance on fossil fuels, provided it can be successfully deployed at scale. Overview has already demonstrated power transmission to the ground from an aircraft and plans to launch its first satellite to low Earth orbit in January 2028 to perform its initial power transmission from space. Meta's agreement includes a capacity reservation for up to 1 gigawatt of power from Overview's spacecraft, with Berte anticipating the launch of satellites to fulfill this commitment starting in 2030, eventually aiming for a fleet of 1,000 spacecraft in geosynchronous orbit, each capable of providing power for over a decade. This fleet is projected to cover approximately a third of the planet, initially spanning from the West Coast of the United States to Western Europe, ensuring solar farms receive supplementary light from space as Earth rotates into evening and night. Berte envisions a flexible system that combines both generation and transmission, delivering power to solar farms precisely when and where it is most valuable, thereby participating in all energy markets rather than just one.
