In plain terms

The 2022 European study assumed it takes two years to build a satellite in orbit, and that getting parts launched could be the thing that makes it take longer.

The claim as recorded

The 2022 ESA/Frazer-Nash cost-benefit study assumes the satellite is constructed over 2 years, states that the construction period may be constrained by available launch capacity, and models sufficient orbital assembly capacity to support that period without stating what that capacity is.

Evidence behind this: T4-commissioned-study, a modelling assumption stated as such.

Scope and limits

NO RATE IS GIVEN - THE ASSEMBLY CAPACITY IS "SUFFICIENT" BY CONSTRUCTION OF THE MODEL. The only modern held source with a construction duration, and it is four times the 1978 figure for a smaller system, which is itself a finding.

What it assumes

A modelling assumption, stated as such.

Where it comes from

SRC-078 Study on Cost-Benefit Analysis of Space-Based Solar Power Generation for Terrestrial Energy...
Verbatim from the held text: "Construction duration The system will be constructed over 2 years. Series manufacture and autonomous in-orbit assembly are key outputs of the development programme and the focus will be to drive down the construction time. Provision is made in the model for sufficient orbital assembly capacity to support this construction period. The construction period may be constrained by the available space launch capacity."

Basis: construction duration, years
