All,

How much electricity is need to roast a Thankgiving turkey & the rest of the holiday cooking extravaganza?

Monitoring baseline data from the Phased Deep Retrofit project being done by Florida Solar Energy Center for U.S. Department of Energy allows us to answer that question. Thanksgiving cooking in our 30 home, all electric sample averaged 2.76 kWh, 2.03 kWh more than it did on the Thursday before Thanksgiving (0.73 kWh)

Note that in the plots below, the left axis scales for Watts vary for each.

Range Circuit on Thanksgiving, November 22nd: Varied form 0 kWh (e.g. Site 5 to 12.4 kWh (Site 7). Obviously, not everyone was home; some were visiting others.



The average demand profile in the overall sample = 2.76 kWh for the day. Note how cooking really ramps off by 11 AM after the Macy's Day parade is done. Sufficiently dosed with Tryptophan, the kitchen manager is immobile by 6 PM...





Range Loads on Thursday, November 15th before Thanksgiving: Varied from 0.0 (Site 27) to 3.81 kWh (Site 5)



Average Profile = 0.73 kWh with most of range power in the evening with a small spike associated with breakfast preparation.




For comparative interest, the same sort of analysis done for another Florida monitoring project 13 years ago. Those data showed in a sample of 70 home with a monitored electric range that Thanksgiving cooking was about 2.5 kWh-- which is similar to what we estimated this year. Shape of the profile also looks similar.

Happy holidays to everyone.

Kind Regards,

Danny Parker

Hi Danny!!  Cool charts!

My Ecobee charts suggest one of my tenants cooked a turkey on Friday, that one furnace mysteriously stopped calling every few minutes.

I'd love to see CO levels across the time..

Interesting look at the numbers & love the side analysis (immobile by 6).  no surprise on it being the same so many years later - tv's might be larger, but more efficient & the BTU's needed then to cook / boil are the same needed today. Be interesting to see effects of induction & convection vrs standard
