The Duck Curve-Solar Power's Greatest Hurdle

submitted by newtboy

6 years 6 months 2 weeks ago

Electricity is incredibly difficult to store, so grid operators have to generate it at the exact moment it is demanded. In order to do this, they create incredibly accurate models of the total electric loads, that is how much energy will be consumed on a given day. But as utilities started to produce more energy from renewable sources like solar, the models started to shift as well.

California researchers discovered a peculiarity in their state’s electric load curves, that started to look more and more like a duck. And that duck shaped chart highlights the greatest challenge to solar energy growth in the US.

(The storage problem has solutions, like dual reservoirs at different heights and huge battery facilities if we would only build them)
