This type of interactive system is becoming more important each day as the desperate IOU electric utilities are ‘playing’ their TOU rate spiking card after solar PV peak generation for the day rolls off into the late afternoon and early evening. During hot summer months, particularly in the desert south and south west in the U.S. ( Phoenix Arizona in 2020 had 144 days of 100 degrees F and over), this creates the 24/7 need for air conditioning during about 4 to 5 summer months and when TOU periods often from 4PM to 9PM often spike residential electricity rates anywhere from $0.25/kWh to $0.45/kWh, that 5 hour period with these onerous TOU rates can cost from around $9 to $17 dollars a day, an extra $270 to $510 added to their monthly electric bills for the month in TOU rates.
