The quest for sustainable energy solutions has taken a groundbreaking turn as Meta has entered into a partnership with Overview Energy, a startup pioneering innovative solar power technology. This collaboration aims to harness the power of a constellation of satellites to beam infrared light to solar farms, enabling them to generate electricity even at night.
In 2024, Meta's data centers consumed over 18,000 gigawatt-hours of electricity, equivalent to the annual energy needs of approximately 1.7 million American homes. As the demand for computational power continues to rise, Meta is committed to developing 30 gigawatts of renewable energy sources, primarily focusing on large-scale solar energy plants.
Traditionally, solar-powered data centers have relied on battery storage or alternative energy sources to operate during nighttime hours. However, Overview Energy, based in Ashburn, Virginia, is revolutionizing this approach by creating spacecraft that capture solar energy in space. This energy is then transformed into near-infrared light and directed toward expansive solar farms, allowing them to convert this light into usable electricity.
By utilizing a broad infrared beam, Overview Energy aims to circumvent the technical, safety, and regulatory challenges associated with transmitting power to Earth through high-powered lasers or microwave beams. CEO Marc Berte emphasizes that the infrared beam is safe for human observation, presenting a unique solution to energy transmission.
This technology promises to enhance the return on investment for solar farms while decreasing dependence on fossil fuels, contingent on successful large-scale deployment. Overview Energy has already demonstrated its power transmission capabilities from an aircraft and plans to launch its first satellite to low Earth orbit in January 2028.
In a recent announcement, Meta revealed it has signed a capacity reservation agreement with Overview for up to 1 gigawatt of power, though the financial details remain undisclosed. Overview has introduced a novel metric, "megawatt photons," which quantifies the light needed to produce a megawatt of electricity.
Berte anticipates launching the satellites necessary to fulfill this agreement by 2030, with a vision of deploying 1,000 spacecraft in geosynchronous orbit. Each satellite is expected to operate for over a decade, providing coverage for about one-third of the Earth. As the planet rotates, these satellites will enhance the electrical output of solar farms during the evening and nighttime hours.
Berte envisions a future where power generation and transmission can be seamlessly integrated, allowing solar farms to receive energy whenever and wherever it is most needed. "There's a significant difference between participating in a single energy market and having a presence in all energy markets," he remarked.
