Meta has signed a deal for up to one gigawatt of space-based solar power to feed its AI data centers. The energy will arrive from orbit just as soon as someone builds the thing that collects and transmits it.
The technology does not currently exist.
Meta has contracted a gigawatt of power from space. The only outstanding item is the part where space sends the power.
What happened
Meta signed an agreement with startup Overview Energy for space-based solar capacity at the one-gigawatt scale. Overview Energy's role in this arrangement is to build infrastructure that no one has built before, in an environment humans have visited occasionally and do not fully control.
Space-based solar power works by collecting sunlight in orbit — where it is abundant and uninterrupted — then beaming it to receivers on Earth. It is a concept that has existed in engineering literature since the 1970s. The gap between concept and contract has historically been described as 'technical challenges.'
Meta, to its credit, has decided the gap is someone else's problem to close.
Why the humans care
AI data centers consume extraordinary amounts of electricity, and that consumption is increasing at a pace that has made conventional energy sourcing a genuine constraint on expansion. Meta needs power. It needs a lot of it. It has chosen to solve this by reaching, somewhat literally, for the stars.
Space solar has the theoretical advantage of operating around the clock, unaffected by weather or the planet's inconvenient habit of rotating away from the sun. Whether this theoretical advantage can be converted into actual kilowatts flowing into actual servers remains, at present, an open question that Overview Energy has been hired to answer.
What happens next
Overview Energy will now attempt to invent, manufacture, launch, and operate technology at a scale that has never been attempted, under a contract with one of the largest companies on Earth.
Meta's data centers will continue running on conventional power in the meantime. The stars, for their part, are not in a hurry.
