Seems the world of how power is priced is starting to change. Utilities want to put off building new power plants and buy expensive power on the spot market so Oklahoma Gas and Electric is offering. about 1/2 off the normal rate except between 2 and 7 pm M-F. Between 2 and 7 the price goes between the 1/2 off rate and about 4.5 times the normal rate. The hotter it is the higher the price.
Right now the program is voluntary and it saved me about $200 bucks last month but I think given the fact that the power industry is not spending billions installing smart meters to help out their customers I think we are going to see a move towards VPP on a mandatory basis.
Right now the upstairs has a 2.5 ton for about 1100 sq feet with expanding foam in the walls and above the drywall. The air handler is in the attic.
The 7 hours it takes to reach 78 is really not good enough.
Here is what I am thinking about.
1. Oversize it big time (5T) so that we can deal with the heat that is trapped up there.
2. Go with a 5T 2 speed unit. Anyone making a ducted inverter system?
3. Go with a 3T and keep the 2.5T as a "helper" to be used for an hour or two to get rid of the trapped heat.
4. Buying and 40 ton chiller on ebay and turn and cool things down in 5min (just kidding)
Looking for your input.
