Britain To Fire Solar Power From Orbit To Antarctica In Energy First
Britain is preparing to beam electricity from orbit to the frozen edge of Antarctica, replacing diesel at one of its most remote scientific outposts and laying the groundwork for space power stations aimed at the South of England.
Antarctic Test Becomes National Energy Stepping Stone
If successful, the first customer for British space-based solar power will not be London or Birmingham but the British Antarctic Survey’s Rothera Research Station on Adelaide Island.

The station, which supports aircraft, ships and climate research across the Antarctic Peninsula, currently relies on diesel generators backed by ground solar panels. In winter, darkness shrinks the workforce to about 20. In summer, it swells to more than 100. Energy is costly. Supply is fragile.
Now the flow of power may reverse direction, from orbit down.
Oxfordshire firm Space Solar plans to assemble vast satellites in space that harvest constant sunlight, convert it into high-frequency radio waves and transmit it to a ground antenna, or rectenna, at Rothera. That signal would then be transformed into usable electricity on site. A short feasibility study is under way, with deployment targeted for the early 2030s.
Economics Shift The Space Solar Equation
For decades the idea stalled on launch costs. That barrier is weakening. Commercial rockets have driven down the price of placing hardware in orbit, reopening concepts first sketched in the 1970s.
A recent government-commissioned assessment by Frazer-Nash Consultancy, Imperial College London and Space Solar Engineering concluded that by 2040, space-based solar could rival nuclear on price if scaled.
Space Solar’s leadership argues Antarctica offers a proving ground where diesel prices are extreme and sunlight on the ground is unreliable. “The Sun always shines in space,” said co-chief executive Martin Soltau, pointing to uninterrupted generation above the atmosphere.
South Of England In Firing Line
The Antarctic programme is not the end goal. It is the opening move.
Much of Britain’s wind capacity sits in Scotland and northern England, distant from heavy demand in the South. A large rectenna in southern England during the 2030s or 2040s could transmit orbital power directly to population centres, easing grid strain and, the company claims, slashing bills without long-term subsidy.
Government remains cautious. Officials note current costs exceed those of established renewables and warn that further reductions in launch expenses are essential. Monitoring continues under wider clean energy innovation workstreams.

That mix of innovation, complexity, and real-world impact is what keeps her interested in the space sector.
