Harley, why do you use some much power for your first meter? Perhaps it's worth looking at efficiency gains to lower your rate. CFLs, different heating sources, insulation and air sealing, etc, compressed air, pumps, etc - sound like they would be a decent investment (depending on what is using all that power) that would lower your usage and your rate at the same time, which could negate the whole issue in the first place.
Sometimes the answer isn't more power, but using what you have more efficiently.
I am in PG&E territory & the base line rates are crazy here too, this is a copy & paste from my bill:
Electric Charges $47.34
Baseline Quantity 114.30000 Kwh
Baseline Usage 114.30000 Kwh @ $0.11877
101-130% of Baseline 34.29000 Kwh @ $0.13502
131-200% of Baseline 80.01000 Kwh @ $0.29062
201-300% of Baseline 14.70000 Kwh @ $0.40029
More.
Charges
01/01/2011 - 01/21/2011
Electric Charges $109.42
Baseline Quantity 266.70000 Kwh
Baseline Usage 266.70000 Kwh @ $0.12233
101-130% of Baseline 80.01000 Kwh @ $0.13907
131-200% of Baseline 186.69000 Kwh @ $0.28011
201-300% of Baseline 34.30000 Kwh @ $0.38978
Net Charges $109.42
Kinda hard to read but a 2nd meter
may be the only way for the OP, but depends on the rate schedule that will be used.....
