Justin Gundlach@feiwang Excellent point.
Also, DOESN'T EVEN MAKE IT TO THE MEME deserves a meme.
@feiwang Maybe something like this? (That's a black swan at bottom left.)
@JustinGundlach Hah! I feel like I am not cool enough to judge memes 😂 But to me, the probability of severe grid issues as a consequence of neglecting distribution networks is predictable and high, especially when we are serious about deploying DERs! Is that a grey swan event? Or is there a more fitting analogy out there?
Dej Knuckey@feiwang @JustinGundlach I’m more worried about T than D though - won’t home batteries, bidirectional EV charging and ever improving efficiency help the D cope, just get by w Xformer upgrades? I know HECO feeder studies showed it copes w much higher resi solar penetration than we expected - acted as a stabilizing force.
(Great to see a real discussion here - so far the old heffalump is not seeing many discussions, just one-off toots or whatever they’re called here.)

Kate Unger@climatefuturist do you have that feeder study handy to share?
It seems to me DERs have huge potential to help reduce the need for distribution grid upgrades, but there’s reason to worry about DER interconnection and integration. They need to be seen as a solution and embraced by the DSOs.
@kateu @climatefuturist I think you’re right to worry about T most. My worries about D vary by jurisdiction and have more to do with the potential for utilities to overspend then for D to be a bottleneck that stymies electrification etc.
@JustinGundlach @kateu @climatefuturist
Definitely agree distribution-level challenges vary greatly by jurisdiction. The DSOs with more progress on distribution network visibility either have to comply with regulations (e.g. UK) or have to manage an increasingly congested network (e.g. Netherlands). And even when DSOs decide their strategy is to overbuild distribution capacity, not only is it costly, there is a long wait: the wait time of new transformer delivery is currently 50-60 weeks.

@kateu I don’t know if the feeder study was made public - but this is the closest I could find though a few years later and a bit off a different spin: https://www.nrel.gov/docs/fy19osti/74091.pdf
@climatefuturist @JustinGundlach DSOs definitely have the opportunity to use DERs to optimize system capacity and prioritize transformer upgrades in constrained areas. In reality, visibility of low-voltage networks is so low (smart meter data not sufficient for network operations), and I have seen DSOs run into difficulties trying to efficiently process more and more connection requests (solar, batteries, EV chargers, etc). DSOs are also concerned about fault management and power quality issues.
