In Germany, wholesale power prices can actually go negative on sunny afternoons. Conditions in the US are trending towards that.<p>Why should actual generators get paid low (or negative) wholesale prices at the exact same moment that some consumer gets paid full retail rates? It doesn&#x27;t make sense.<p>Very practically, this is illustrated by California&#x27;s duck curve. Also from Bloomberg:<p><a href="http:&#x2F;&#x2F;www.bloomberg.com&#x2F;news&#x2F;articles&#x2F;2015-10-21&#x2F;california-s-duck-curve-is-about-to-jolt-the-electricity-grid" rel="nofollow">http:&#x2F;&#x2F;www.bloomberg.com&#x2F;news&#x2F;articles&#x2F;2015-10-21&#x2F;california...</a><p>It has nothing to do with Musk and Buffet. How do you price power, both wholesale and retail, in a way that recognizes that there&#x27;s a need to provide power even when it has been overcast for three weeks?
