Agree! Home battery storage can pay for itself in only 2 years IF AND ONLY WHEN the PSC and utility will actually pay the homeowner the true cost of the electricity when they draw it back. (or in this case where one uses ON-PEAK electricity in a high cost area but gets a deep discontut off peak. In my area, TOU was 10 cents daytime and 2 cents at night. Great! Then they deregulated and the rates becamse 12 cents peak and 10 cents off-peak. Not worth the trouble! Maryland offers a 30% tax credit for Powerwalls and Home energy storage, BUT THEN HAS NOTHING IN PLACE TO USE THEM! Customers are being sucked into to buying huge batteries just to have them sit there for the average 4 hour outage once a year (about $1 worth of lost electicity). Cleary the progressive idea of home battery was there, but no followthorught to change the billilng system to PAY homeowners premium for the value of that on-peak electricity. The local utility DOES pay $1.25 per kWh for every kWh you *do-not* use on peak grid days, but that is only 5 days a year. But it proves to every Maryland resident that there is VALUE in having access to peak battery power when the billing system catches up to it.
