Actually, you'd want to store (renewable) energy when there is a surplus. The market for grid storage is fast growing and I hear little about the old tech of rotating (flywheel) storage and adding pumped storage is not easy to grow either due to real estate, the only area that I hear massive investments in is in battery.
Surprisingly, one of the ways to add storage and stabilize the grid is by installing a specific version of Fast Charger. While the Fast Charger is often villified for its potential to upset the grid due to high and unexpected loads, it can also be installed with battery storage that allows low installation cost due to requiring only a moderately amount of connected power with the battery averaging the load out over a longer period but at the same time allowing the battery to be used in demand load control and possibly even in power generation, depending how the electronics is set up. This allows a Fast Charge station to be installed in a residence of a (wealthy) individual without need to change the service connection, a simple 240V 50A connection can charge a battery bank overnight if needed, or whenever it is cheaper or more desirable to pull electricity off the grid, in addition a (large) PV system can feed into the bank, to give it power when a grid failure occurs. Charging from the bank can happen at any speed that the batteries and the electronics can sustain, 50 or even 100kW power is no problem, even while the grid connection peaks at 12kW. BTW, this system already exists, EMW has developed it and when this gets rolled out, it is a great addition to the ever increasing grid storage. Note: there is no reason the house could not be powered from this as well, so essentially it becomes a "PowerWall". The vision that I have is that an affordable version of this system can be offered with *used* EV batteries as the requirements for weight and size are much less in stationary installations and this gives a good second hand market for used batteries from EV.

Actually, that is the reverse of what you want. You want to store during the night when demand is low, then use during the day when demand is hi. -- Try my Sensible Email package! https://sourceforge.net/projects/sensibleemail/ _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA) _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
