I just noticed it's been a while. New members welcome. This group started out of a common interest in sorting out the truth about wind and solar and how our suspicion about an all of the above energy policy is not a wise idea. The latest bit I have heard is from Spain offered by Alex Cannara in our facebook group energy realityhttp://www.facebook.com/groups/energyreality
"By the way, we attended a presentation by a Spanish economist re wind markets in Spain. They do crazy things like subsidizing wind farms, but allowing them to do arbitrage -- sell more than capacity 1 day ahead, but buy back power on the market as the next time divisions occur before delivery. They thus make $ ahead, shore up their shortfall at lower prices, and eventually deliver less than their 1st bid. For them, the subsidy + wind variability offers money-making opportunities.
The economist said they're not building more wind because it's too expensive. And, the market goofiness needs fixing.
I hear also that some Euro wind farms are declaring not "nameplate" capacity, but something like ~70% of that ("registered" capacity), so they can avoid certain fees and not look so bad in the market as winds vary. This may encourage arbitrage as well."
