I read through, it's just that there has to be some sort of definitional issue here, because what you have and what the Spanish government is reporting don't match.  That could be because they are for self use, or because many of these projects on the list you have are still in the construction phase.

Regardless, in times of austerity, it's sort of hard to convince people who are looking at reduced wages that the government should be shelling out cash at the rate imagined here. This is a lot more data than I'm going to swim through right now, but there's general agreement that the targeted cut in the FiT was a good call.

One of the big problems that's unique to Spain is that industrial electricity rates are 85% of residential rates, while in neighboring France they industry only pays only 67.5% of what residential does.  Purchasing a Mwh for an industrial operation in Spain will cost, on average, €109.80/Mwh.  In France that same amount will cost a factory  €64.70/Mwh.  So industrial electric costs are 70% higher in Spain than France.  That's a huge impediment to economic growth.

That issue with industrial prices is what's driving government action more than residential prices.  Cutting non-labor costs of production removes some of the push to slash wages.

FYI, where was your spreadsheet at, I found the thing online, but no excel file?
