I have huge problems with this, even though I personally have home solar and batteries (in Alabama, not NY).
1) One problem is, whatever the bureaucrats control they mess up. If you want to get into why my solar works pretty good (80% of our power is provided from homemade solar, with only 20% coming from the grid), and grid solar and wind work so poorly, it's because I have a vested interest in making sure mine works both effectively and efficiently.
2) The 2nd problem is that lithium battery storage returns at best 90% of what you put into it. In other words, there's loss of energy to store it and use it later. For example, my LifePo4 lithium-ion batteries took in a total of 12,066.7 kWh, and I got out of them 10,880.5 kWh. That means that 10% was loss on average through the process of storing power while I had excess, the batteries holding the power for a few hours, then discharging the power from my batteries when my home needed it and there wasn't enough solar (i.e. at night, but sometimes part of the next day during rain).
3) Item #2 above assumes no DC to AC conversion or back. Looking at the telemetry I get from my EV's OBD2 port, when charging at 9.4kW from AC at home, only 8.4kW DC is going into the battery to charge it. A loss of 11%. So will these batteries be charged with excess AC power, which means converting that to DC to store the power, then converting back to AC to distribute the power on the grid? The AC to DC conversion loss, then combined with loss while charging and discharging the batteries, combined with loss to convert back to AC might add up to 30% or more loss.
Just so the Dims can feel good about saving us from the Modern Warm Period.
