Texas’ capacity was 113000 MW yesterday so 1.5MW doesn’t seem significant. Am I understanding this wrong?

Wrong comparator. 1.5MW nominal output is comparable to a large wind turbine.

For instance, there's the https://www.esig.energy/wiki-main-page/general-electric-1-5-..., which has ~40m blades. The AR1500 (which is what these tidal generators are using) is smaller, with "only" 9m blades.

So it's significant in that these aren't toy devices, they fit in a very similar place in the engineering ecosystem as conventional wind. They should be a real competitor.

  • In 2025, the large commercially deployed wind turbines are like 15MW for offshore and 6MW for onshore.

    GE's 1.5MW models are 20 years old.

Are you really comparing a single experimental turbine's handwaved output with the consumption of an entire state with a population as big as the bigger European countries?

Yeah, and a solar panel might only produce 250 watt, that would mean solar is also not significant /s
