Space based solar power

Space based solar power () is the concept of collecting solar power in a high earth orbit and beaming it securely to a fixed point on the earth. Its main attribute is the ability to deliver clean, baseload energy, day and night throughout the year and in all weathers. Recent technology and conceptual advances have increased the potential viability of . In response, the government has commissioned 2 studies to assess the opportunity and pathway to deployment.

1. Space based solar power: de-risking the pathway to net zero (2021)

This study looks at the technical feasibility, cost and economics of space based solar power as a novel generation technology to help the UK deliver its net zero policy. It also identifies key risks and recommendations for development.

The technical reports which support this document are available on the Frazer-Nash website :

• the Phase 1 report contains a review and analysis of the engineering feasibility of
• the Phase 2 report presents an assessment of the likely cost and economic contribution of as a possible future energy technology in the UK

2. Feasibility of small-scale space based solar power systems for early market adoption (2025)

Building on the 2021's feasibility study, this study explores whether smaller-scale systems could enable early commercial adoption in the 2030s, reducing investment risk compared to gigawatt-scale architectures. It compares current designs and defines a minimum viable product () that maximises grid utility and investor return. It also explores alternative markets including global opportunities, assesses benefits to the energy system, and evaluates financial feasibility under government support mechanisms.
