For my own sanity — and as the unofficial moderator of The War on Cars account — I'm actively muting anyone who thinks "Not everyone can bike everywhere, you know" is a cogent argument against reducing car dependency.

I've taken the attitude of @notjustbikes to heart and simply don't have patience for it anymore.

@jtemple this perspective also takes focus away from those who purposely held back electric vehicles

OK this is interesting. Mozilla starting a Mastodon instance next year...

@chazteplin @rkonidena76 not sure I follow your point. If you are proposing a wind or solar site and the grid operator wants to build fatter cables to accommodate it, or to approve the interconnect, then the battery certainly helps since you (as a developer) can keep the peak power through the interconnection down. But the grid operator needs to understand that role to approve the connection. Note that the battery also provides many valuable services to the grid operator (frequency control, short circuit power, flatter ouput from the VRE). I disagree that grid operators are only looking for generators to serve baseload.

@rkonidena76 thanks Rao, that's very interesting. Looks like you were advising MISO on storage policy. Do you predict any changes or improvements in the near future? It also seems like the IESO here in Ontario does not understand battery applications very well

@rkonidena76 is that everywhere in the US? I've heard complaints of this before and it's really a shame, as this is one of the big values of short term storage

@hausfath to be clear, that waiting solar and wind would not be able to completely replace existing generation capacity, but it would likely reduce fossil fuel usage for electricity by about half (I would guess).

Any idea why more developers don't co-locate batteries to avoid grid upgrades? Should pay for itself in opportunity costs alone I would imagine!
