Use Solar as a Hedge
Pricing in ERCOT is coming out of a stretch of historic low pricing. So many customers go used to the low pricing as a norm and are now experiencing sticker shock. Especially those who have supply contracts that expire in 2018 and 2019. Beyond working to get a low supply contract you should consider solar as a hedge against rising prices.

You will not be alone. Solar is undergoing a revolution in the USA and Texas is the next prime candidate.
