Space based solar power (SBSP) 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 made the concept worthy of consideration by the UK.
This independent 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.
The executive summary contains:
- net zero context
- description and background of spaced based solar power
- engineering feasibility and risks
- cost and benefits
- conclusions and recommendations
Space Based Solar Power development
This study supports a case for developing SBSP, so the government is considering this further:
- how it could potentially support innovation in the development of relevant technologies that are dual use
- which as a result could be used either in space based power systems or terrestrial power systems
We welcome your input:

BEIS commissioned Frazer-Nash Consultancy to conduct the study. 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 SBSP. It includes a review of leading SBSP concepts, an assessment of the underpinning technology maturity and engineering barriers to realise SBSP, as well as technological roadmaps for the development of a 10GW SBSP capability in the UK and internationally
- the Phase 2 report presents an assessment of the likely cost and economic contribution of SBSP as a possible future energy technology in the UK
The study supports a case for developing SBSP and the government is minded to fund an innovation programme looking at developing relevant technologies that also have broader terrestrial applications and could still contribute to UK’s climate change commitments, whether SBSP is deployed or not.
