UK Government Study Finds Space-Based Solar Could Be Cost-Effective by 2040
A UK government feasibility study suggests that space-based solar power could be economically viable by 2040, provided launch costs decrease as predicted. The levelized cost of electricity for orbital solar plants is expected to drop significantly, making it competitive with nuclear and tidal energy. The study identifies key cost drivers and potential market opportunities, indicating that small-scale systems could pave the way for larger projects in the future.

The UK government's feasibility study indicates that space-based solar power could become economically viable by 2040 due to anticipated reductions in launch costs. The levelized cost of electricity for orbital solar plants is projected to fall from GBP 0.0335-0.0595/kWh in 2030 to GBP 0.0087-0.0129/kWh by 2040.
Launch costs, accounting for over 50% of the cost variance, are estimated at GBP 550/kg in an optimistic scenario. The study also predicts a decrease in the hurdle rate from 20% in 2030 to 9.1% in 2040, enhancing project viability.
Potential applications include support for small island nations and various industries. Small-scale projects are expected to facilitate the development of larger systems.
