In plain terms
The UK's fast-response grid support services need a generator to react within seconds, at any moment over a 4-hour period. A ground receiving station on its own could not promise that, so it would need its own battery to offer this kind of service.
The claim as recorded
GB frequency-response ancillary services are contracted over 4-hour windows requiring the supplier to respond within seconds if called upon, and the report concludes that a rectenna could not deliver these services unless co-located with a battery able to guarantee delivery at any point in the 4-hour window.
Scope and limits
This is Frazer-Nash's own analytical conclusion for the GB market and this specific reference design, not a demonstrated technical limit of rectenna hardware in general, and does not address ancillary-market rules outside Great Britain.
What it assumes
The rectenna's power output cannot itself be modulated on second timescales independent of the incoming beam; a co-located battery is the only route to meeting the response-time requirement.
Where it comes from
p.34: "Frequency response services are contracted over 4-hour windows (electricity forward agreement (EFA) blocks), during which the supplier must be available to respond (on timescales of seconds or less) if required. For this reason, delivery of these services would only be possible if the rectenna were co-located with a battery that could ensure delivery at any time within the EFA block." Confirmed verbatim against the PDF text layer.
Basis: Great Britain ancillary-services market rules (frequency response, EFA blocks)
