Not really, it's the velocity the "Breakthrough Starshot" probes would reach. They propose[1] that launching each probe would take 84 GWh, which is not super much (about 15 times more than a space shuttle launch), but of course the Starshot probes would be much lighter than this proposed telescope so it's not directly comparable.
