Just glad I'm of some use to someone, you're certainly welcome.
I like your planning on this. I wanted to do some of the same things but just didn't have the cash at the time.
I deal in power and the transmission of that power eight hours a day. It doesn't matter what the media tells you, electricity will not get cheaper no matter what. When they deregulated our industry we gained several thousand players that all want to make a buck, prices can only go up for commercial power.
It is possible to play the market with your own use IF you have some sort of secondary power supply. I really wish you luck with your plans.
And thanks for taking care of the dog.
