A marginal effect given thermal plants run their steam at hundreds of degrees. The efficiency difference between 800/280 and 800/310 isn't very large.

  What kind of margins are we talking about here exactly? How does it compare to the demand-side problem of increased AC usage?

  Enough to reduce output by 5–10%, which is less than useful when demand is peaking. 800 - 280 = 520, 800 - 310 = 490. That’s a change of about 6%.
