Meta has announced a partnership with Overview Energy to bring space-based solar power to its data centers, securing capacity for up to 1 gigawatt of orbital energy. The technology uses satellites in geosynchronous orbit roughly 22,000 miles above Earth to collect constant sunlight and beam it down to existing solar farms as low-intensity near-infrared light. This approach could allow solar facilities that currently sit idle at night to keep producing electricity around the clock without requiring additional land or grid infrastructure.

How Does Space-Based Solar Power Actually Work?

Overview Energy's system operates on a straightforward principle: satellites positioned where sunlight never stops collect solar energy in space and transmit it wirelessly to ground-based solar farms. The existing solar infrastructure receives this beamed energy and converts it into electricity using the same technology that handles direct sunlight. Because the system builds on infrastructure already in place rather than requiring entirely new facilities, it can scale faster than traditional solar buildouts.

The technology addresses a fundamental limitation of conventional solar power. Today's solar farms only generate electricity when the sun is shining, leaving them idle for large portions of each day. Space-based solar eliminates this constraint by providing continuous energy input, even during nighttime hours on Earth.

What Are Meta's Energy Goals Beyond Space Solar?

Meta is pursuing multiple strategies to power its expanding data center operations with clean energy. The company has contracted more than 30 gigawatts of clean and renewable energy to date, representing billions in capital investments. Additionally, Meta is one of the largest corporate purchasers of nuclear energy in American history, supporting 7.7 gigawatts with multiple providers.

Beyond space solar, Meta has partnered with Noon Energy to deploy ultra-long-duration energy storage using modular, reversible solid oxide fuel cells and carbon-based storage technology. This system provides over 100 hours of energy storage, far exceeding what today's lithium-ion batteries can deliver. These complementary investments reflect Meta's recognition that data centers require diverse, reliable power sources to operate continuously.

Steps to Understanding Meta's Energy Innovation Strategy

• Space-Based Generation: Overview Energy's satellites collect solar energy in constant sunlight 22,000 miles above Earth and beam it to ground solar farms as near-infrared light, enabling 24/7 renewable power generation.
• Long-Duration Storage: Meta's partnership with Noon Energy deploys solid oxide fuel cells capable of storing clean energy for over 100 hours, addressing the grid's need to carry renewable power through extended periods without sunlight or wind.
• Diverse Power Portfolio: Meta has secured 30 gigawatts of renewable contracts and supports 7.7 gigawatts of nuclear capacity, ensuring data centers have multiple reliable energy sources beyond experimental technologies.

When Could This Technology Actually Reach the Grid?

Overview's orbital demonstration is planned for 2028, marking the first time the system is scheduled to beam energy wirelessly from space to a solar farm on Earth. If successful, commercial delivery to the US grid could start as early as 2030. However, significant uncertainties remain. Beaming energy from space to Earth at commercial scale has never been accomplished before, and the efficiency of that transmission remains unproven. The infrastructure required to receive and convert beamed energy across hundreds of solar farms does not yet exist.

Meta is placing substantial bets on unproven technologies because the potential payoff would be transformative for data center operations. Noon Energy's carbon-based storage technology also faces questions about cycle life, degradation, and manufacturing scale. Despite these risks, Meta stated that "the potential to make existing infrastructure produce more output is what makes space solar worth investing in now to help move this technology from concept to the grid".

Why Are Data Centers Pushing Energy Innovation?

Data centers consume enormous amounts of electricity, and the demand continues accelerating as artificial intelligence workloads expand globally. State regulators and legislatures across the United States are implementing new policies to address the massive power demands of expanding data centers while protecting residential ratepayers from cost increases. Public utility commissions in states such as Wisconsin and Minnesota are developing customized tariffs and electric service agreements that require data center operators to bear the costs of new generation and storage resources dedicated to their loads.

This regulatory environment creates both pressure and opportunity for companies like Meta to develop innovative energy solutions. Rather than waiting for mature technologies, Meta is investing in early-stage systems now because the company recognizes that conventional power sources alone cannot reliably support the scale of future data center expansion. Space-based solar and ultra-long-duration storage represent Meta's hedge against energy scarcity and grid constraints that could otherwise limit AI infrastructure growth.

The company's multi-pronged approach, combining experimental orbital power, advanced storage, renewable contracts, and nuclear capacity, reflects a strategic recognition that no single energy source can meet the demands of next-generation data centers. If Overview Energy's 2028 demonstration succeeds and commercial deployment follows by 2030, the technology could reshape how the technology industry powers its most energy-intensive operations.
