@Bob ,
In my opinion, based on the limited info presently available, the cyclical peaks and valleys represent weekday and Saturday lights and mundane warehouse loads. The lights in the warehouse are old things, maybe HP sodium, metal halide, or similar, that use a substantial amount of electricity. Maybe Rossi manned the Plant on Sundays and did not use the warehouse lights.
It can be supposed, although only a best guess, that the weekday lighting etc. loads can be subtracted from the FPL lumpy line to arrive at the base warehouse load, which includes the Plant consumption.
The Plant carries on through Sundays at 3/4 or full nameplate capacity (or close), in theory, even though the warehouse seems to have no need for lights, etc. during that day. I am sure many excuses/explanations will be made for the Sunday production of steam for the Customer while the employees are absent or don't require lights etc. on Sundays.
But why the plant was able to consume more electricity than was supplied for the two week period in November has fewer excuses/explanations. The idea that FPL had a separate meter for the Plant I am sure was looked into by IH when they got a subpoena to look at the warehouse consumption data. Remember also that Matts had an electrical bill for JMP, which was once used as "proof" that the Plant was making substantial excess heat.
(10 x 400W Metal Halide bulbs would explain most of the electrical consumption lumps, of they were on all day, or almost all day, on weekdays + Saturdays)
Conveniently, Rossi supplied monthly data for the (more or less) unoccupied Doral warehouse suite in the Exhibit in Document 128-02, showing about 15 kWh per day average when empty.
