A heat wave will last until the end of this week in the San Francisco Bay Area. Temperatures 100F (38C) or so all week. Today is the fourth day out of the last five days with a Virtual Power Plant event. Tesla has created the software so that the utility PGE (Pacific Gas Electric) can tap a few thousand houses with solar power and Power wall batteries.
Ten Virtual Power Plant events with each about two to four hours in length will total to about 30 hours. Participant electricity providers get $2 per kilowatt hour or about $20 per hour. This will total to about $600 in 23 days.
Temperatures will then drop to 80s F. If PGE still needs help with temperatures in the 80s then VPP could total $3000 this year with operations covering less than half of the hot season. A hot summer next year could see an average of $6000 worth of VPP to each household in the program. If it is mainly 90F+ days then the VPP would pay out about half those amounts. PGE is way behind on building and keeping power supplied. It is possible that VPP participants could see $6000 per year from VPP every year to 2030 and beyond. They can also get $500 per year from net metering and $3000 per year electric bill savings.
If this makes $9000 per year would see a payback period of less than four years for the solar and power walls.
If the Solar Panels and Power Wall batteries last 25 years then even at an average of $2500 per year in VPP, net metering and electric bill savings this would be a $150,000 in value over 25 years.
