I don't have any experience in large storage but I know Dynapower in Vermont is working on a storage solution. You should check them out: http://www.dynapowerenergy.com/

I know that most of the latest utility scale inverters have some ability to control the rate that power ramps up and down, but what is the time scale? Is it milliseconds, seconds, a minute? Also, they are hankering for some type of storage, so beyond the inverter controls, what are some of the available short term storage strategies (2 to 4 hr) these days? I've heard of several prototype large battery banks (and fires?).... Anyone on the list have experience with these?
