Miliband Targets The Sky With Radical Plan To Beam Energy From Space

Why It Matters

If realised, orbital solar could provide reliable, carbon‑free power at competitive rates, reshaping the UK’s energy security and decarbonisation strategy.

Key Takeaways

• Orbital solar could deliver gigawatt-scale, constant power
• Projected 2040 cost £87‑£129 per MWh
• Public funding needed for early-stage satellite deployment
• UK aims to lead with Space Solar startup partnership
• Space‑based solar rivals offshore wind and new nuclear costs

Pulse Analysis

The United Kingdom is turning a speculative sci‑fi concept into a cornerstone of its net‑zero ambition. By commissioning a study that maps out orbital solar farms, policymakers aim to bypass the intermittency that hampers wind and rooftop photovoltaics. The technology hinges on ultra‑light panels mounted on satellites that harvest near‑continuous sunlight, convert it to microwave energy, and beam it to massive rectennas on the ground. This approach promises a steady, weather‑independent power supply, directly addressing the nation’s growing electricity demand and energy‑security concerns.

Cost competitiveness is the linchpin of the proposal’s viability. Early‑stage projects would demand heavy public investment to de‑risk private capital, yet the study projects a steep decline in levelized cost of electricity, reaching £87‑£129 per megawatt‑hour by 2040. Those figures sit alongside current offshore wind contracts and undercut the £150 per MWh forecast for new nuclear builds. Such economics could make space‑based solar not just a symbolic venture but a commercially attractive addition to the UK’s generation mix, potentially displacing fossil fuels and smoothing the output of intermittent renewables.

Strategically, the move signals a bold industrial bet for Britain, aligning with global momentum from the European Space Agency and China’s gigawatt‑scale orbital ambitions. Partnerships with startups like Space Solar and the UK Space Agency aim to accelerate hardware development and self‑assembling satellite capabilities. Success would cement the UK’s position at the forefront of a nascent market, creating high‑tech jobs and export opportunities while delivering a resilient, low‑carbon energy backbone for the mid‑century economy.
