    power systems in those areas will want to take extra precautions. Most areas don't have to worry about it much.

    But remember, volcanoes can give even fossil-fueled systems a bad day; see e.g.
    volcanoes.usgs.gov/volcanic_ash/power_supply.html
    volcanoes.usgs.gov/volcanic_ash/power_generation.html

    Since the activity was on the big island I believe the number of solar pv installations is small compared to the more populated islands. That is good for those solar farms because I would hate to have them go useless due to a mild fart of ash. What bothers me is that everyone seems to want to use old data on ash emissions which could be a big mistake if something new explodes.

    Almost as bad as using our old weather patterns to predict what will happen since due to our changing climate (which you are very aware of) is also making an impact on all RE production including hydro which have run out of water in the catch basins due to lack of rain.

    And yes fossil fuel powered generators are also affected by what is in the air and water but small packaged reactors can ride out a weather event and still produce. IMO it would be smart to not only invest in "storage" systems like batteries but also a type of power generation that is not affected by our changing weather patterns or ash emitters.

    I wonder how Hawaii is doing with solar power generation since the volcano put all that ash in the air.

    I am all for installing solar or wind because it helps but unless people reduce their consumption and find ways to generate power regardless of the weather conditions most people will find it very hard to get even close to having 100% RE power. The worlds weather and ash belches will hopefully get people to realize their folly of being too dependent on RE.

    Yes, real time pricing would get things moving in the right direction! It's painful for some users, though. California's approaching this slowly, and has been phasing in a rough approximation to it (TOU pricing) for some time.

    My impression is that California's realizing that, if your goal is to reduce carbon emissions, adding solar by itself becomes less and less useful as the grid becomes saturated with it; to be useful, it needs to be coupled with other measures like load shifting, peak shaving, and time-of-use pricing.

    The rules approved today by the energy commission ( utilitydive.com/news/california-to-require-rooftop-solar-for-most-new-homes/523200/ ) would require solar on many new buildings, but also encourage storage, particularly storage that is responsive to TOU pricing and other utility signals. For details, see energy.ca.gov/title24/2019standards/rulemaking/documents, click on "2019 Reference Appendices"; appendix 11 is about PV requirements, appendix 12 is about storage. It's interesting stuff; it seems clear they're learning from Hawaii's experience. (See also utilitydive.com/news/solar-has-transformed-into-solar-plus-storage-what-will-net-metering-becom/522893/ for some more thoughts on the subject.)

    I think part of it is I disagreed with SK and JPM. That alone drove them nuts

    But the bigger picture is - they're part of the folks that are convinced that humans aren't causing climate change, and posting any science on the topic - or any news related to reducing greenhouse gas emissions - triggers them pretty hard. The forum's current owner appears to agree with them, too.
    The other side of the equation is that SK and JPM are genuinely helpful people, with strong technical skills, and that's very valuable to the forum.
    The upshot is, they get a pass for behavior that would get them kicked off quickly on less polarized forums.

    Anyway, they've been gunning for me for some time, and seem to attack anything I say, no matter how neutral, factual, or careful it is. C'est la vie.

    Ok , I did do some research on him before I posted and saw him post and then get ripped and he stayed civil and did not give it back to you guys so I felt sorry for the guy but I will do some more digging and just see want he said that was so wrong.

    I mean I wouldn't want Dan to start calling you SunQueen everytime he didn't like something you said, lol
    Most of what Dan brings to this venue is repeats and rehashes of stuff from mostly one side of the issue that abound the airwaves, press, social media and the net.. He's been prevented from attaching such stuff to his posts mostly for that reason, and also because a lot of his reposted fluff doesn't stand the light of day, or is mostly irrelevant to anything practical or useful - kind of like junk science. That's not much more than a waste of time for knowledgeable folks who know better, and makes a lot of us pity Dan for what some of us see as childlike behavior and motivation(s). But for the solar ignorant who show up here looking for some real information, it can cause some real problems when they read Dan's rehashed tripe and attach some veracity to it by virtue of its official looking origins, ascribe some veracity to it and wind up going down a wrong road waste of time and resources when they're led to believe R.E. potential for good is greater than a more sober outlook would allow.

    More not that anyone cares: IMO only, that's rude, inconsiderate, selfish and unacceptable behavior. I go after Dan's antics for those reasons. Like a child who gets scolded for inappropriate behavior, Dan thinks I don't like him for calling out what I see as his often inappropriate and likely harmful behavior. Reality is, and facts are, seems like I've always known someone before I would like/dislike them. Dan and I have never met. But, I think I know B.S. when I smell it and Dan's posts often have a familiar scent to them. I sort of think it's kind of a public service to call B.S. on Dan's spoor when I think I see it. Other's do the same for their own motivations. In that respect, I believe I'm in good company.

    As for Dan's motivation, not that anyone cares, but my guess is that Dan is a "me-too" wanna be of R.E. of the "you could just and simply do this and the world would be better" school that doesn't take time to understand the details (where the devil seems to often reside) but wants to play with the big dogs.

    But, since this is a place to exchange information and opinion, Dan seems to think and act as if he's free to abuse the privilege. Other's are just as free to call B.S. on his stuff as they see the need, public service or otherwise.

    Would not bother me 1 little bit, I do not let words bother me. You have to weak to allow that to happen and lived a sheltered life. You have not been around long enough or you would know Dan is here only to make trouble and get the crap kicked out of him. Mods would ban him if they could and he has been banned a few times temporarily to make him leave. Do some homework, Dan gets the crap kicked out of him all the time even by the moderators and admin. Facts and logic do not apply to him, RE is a religion to him no matter what the cost. Go do a search he goes to a lot of forums pitching his agenda. What he really advocates is raising gasoline tax so high, no one can afford gasoline except the rich. Dan is quite wealthy and can afford what working people cannot.

    I tried it your way, does not work. Many people have tried. He comes back once in a while, throw his propaganda out to see if we are still looking out for him. He likes being kicked.

    problems be accepted by the public.

    Here in northern IL have been net zero for years, but it would not work if every customer did it.
    Collect energy in the summer, use it up in winter. Its a huge problem for the PoCo, but I hope they
    are working hard on it. Bruce Roe

    Solar would be included with new homes just like a water heater and central air conditioning .

    Along those lines, it's interesting that electric meter maker Itron and storage vendor Sonnen announced a partnership recently. Some towns already require solar on new houses; requiring 4kwh of storage as well, and using it to reduce peak system load to avoid adding peakers, may well be in the cards someday.

    Tesla already raised their Powerwall 2 price $400 two weeks ago-

    https://electrek.co/2018/04/21/tesla...ice-powerwall/

    So what is your opinion on the incentives azDave ? I wonder if APS will follow suit.

    Plan on the prices for such storage systems going up something like the about same amount as the POCO incentive.
