Re: [Shared Post] 'A game changer': How giant batteries are making California's power grid stronger, and reducing the risk of blackouts during heat waves
The combination of wind+solar+storage (and maybe hydro) is a renewable energy solution. Apparently, California now has enough grid-scale storage installed to be able to time-shift lots of excess solar-power from daytime production to evening consumption.? I know of this from Tweets by Prof. Mark Jacobson throughout this year. The issue is what's called "The Duck Curve" which refers to the shape of energy production on the grid as more and more solar resources come online.? When the evening comes, the sun goes down, the winds tend to die down, then renewable energy is not available, and the utility companies have to quickly ramp up something like natural gas peaker plants. The purpose of the grid-scale energy storage is to instead soak up solar energy during the day, release it during the evening/night, and avoid using fossil fuel plants. "Energy storage" doesn't have to be lithium-ion batteries.? For example there is "solar thermal" systems that can heat up something simple like rocks, that can later be used to drive a turbine. -- This video might have some information.? The guy who recorded this video is in Ukraine, and has been researching and talking about cheap technology for solar thermal systems. As for "restricting electric use during the hottest part of the day" and TOU?pricing ... There is a thing called Demand Response.? There is a protocol, OpenADR, that is frequently used for implementing Demand Response programs.? I have for the last 2 years been implementing software that can be used to build an OpenADR program. These have been in use in California for many years.? For example owners of pool pumps can sign up with a demand response system and if the electric grid is in trouble the pool pump can be turned off for a couple of hours and the pool pump owner is compensated for that service. Consumers have been willing to sign up for such programs and get compensated for their service. The purpose for which I've been implementing OpenADR is to bring this to electric vehicle charging systems.? I'm working for an EV charging network that operates in the New York City area.? The idea we're looking at is to modify the EV charging rate based on the needs of the local electricity grid. As for "the average consumer does not want to be bothered with restricting their electric use during the hottest part of the day" ... yeah, I have some experience about that this summer. Here in Romania?where I'm currently living, it's been a brutally hot summer, and the national electric grid nearly collapsed in July due to a massive heat wave. One thing which happened is the Minister of Energy issued a request for citizens to do an informal demand/response - that is to limit electricity consumption during the evening.? But, this drew an angry response in that people wash their clothes etc during the evening. The Minister of Energy also said they're exploring demand response systems.? I've been unsuccessful in finding out more details, however. + David Herron On Thu, Aug 22, 2024 at 7:52?PM Ben White via <BenWhite=[email protected]> wrote:

Re: [Shared Post] 'A game changer': How giant batteries are making California's power grid stronger, and reducing the risk of blackouts during heat waves
¿ªÔÆÌåÓýDave,You have a couple of good points, grid-scale storage is not the holy grail, and electric rates for most Californians are sky-high, and not just because of the peak-consumption problem.? I'm not that familiar with SCE, but for those of us in PGE territory, some of those costs are the result of huge legal settlements due to wildfires, and the capital cost of moving distribution lines underground. Time-shifting the load on the grid is certainly cheaper than battery farms, but would TOU billing in practice be more effective than batteries?? That's not really addressed in the KTLA news article, but in my experience the average consumer does not want to be bothered with restricting their electric use during the hottest part of the day.? One could even guess that this mindset is the reason that EV adoption has been so difficult:? why would Joe Average Guy want to spend half an hour parked at a charging station when they could fill up their ICE vehicle at a gas station in 5 minutes?? I'm not saying I agree with this thinking, but sadly, it is pervasive. Ben On 8/21/2024 8:58 AM, dave noran via

Re: Fw: Problem with Tesla Model 3
Oh my!? As a wire and cable engineer, I can only say "what were they thinking???". Solid core (single strand) cable has no place in a vehicle, period.? The cheap-out "remedy" of increasing the bend radius WILL bite them in the backside, mark my words.

Hi George, Have not had this problem. My Model 3 for all practical purposes is a perfect car, and one of the best cars ever made. I am a lifelong car enthusiast, racer and general car nut. Tesla issued a recall for the video cable that connects to the rear camera in the trunk lid. They used a solid core cable in some cars that can eventually wear out. The recall action is to install a clip to increase the bend radius around a corner, or replace the cable if it's actually worn. Wear may vary based on the number of times the trunk has been opened and/or other factors. All of my few interactions with Tesla service have been very positive. Suggest you contact them. Jeff C. |

Fw: Problem with Tesla Model 3
Hello All
For the last couple of days I have been having an intermittent problem with my Model 3. Sometimes when I start the car there is a warning message about the brake hold not working. Also, the backup camera and cruise control does not work. The next time I drive the car, everything works. Has anyone else experienced this problem and what is the fix? Thanks! George |

Re: [Shared Post] 'A game changer': How giant batteries are making California's power grid stronger, and reducing the risk of blackouts during heat waves
Ben,?? Right about now electricity customers in SoCal would like grid-scale battery storage to be at fuller fruition. Time of use billing would appear to be far more effective and/or cheaper for utilities than larger batteries at reducing blackouts. namaste

¿ªÔÆÌåÓýHello,The ride-and-drive event at Lake Cunningham Park is just over a week away:? Saturday August 24.? Details are below.? While we're hoping some of you can find time to drop by, we are particularly looking for another one or two members to display their EV at the EVASV booth.? We tentatively have George's Studebaker and my Nissan Leaf, and we have room for up to two more vehicles.? This will be for display only; visitors will not be riding in your EV. If you're interested, please email me at bw20240824@.... Ben ---------- Forwarded message

We
mistakenly gave the event date as Saturday, September
24, 2023 in the message. AUGUST 24, 2024 is the correct
date as stated in the Subject.

San Jose EVA meeting Aug 10, 2024 10-12
Hello All,
If you are interested in Electric Vehicles, consider attending one of our meetings. All EVA meetings are free and open to anyone who is interested in Electric Vehicles (EVs). The meetings are held on the 2nd Saturday of every month. From 10 A.M. until 12 noon The meetings are held at the Reid Hillview Airport terminal building. Located at 2500 Cunningham Ave, San Jose, CA Directions to the meetings are as follows. Take Hwy. 101 to Hwy. 680 North, exit & turn right onto Capital Expressway. Travel on Capital Expressway West for approximately 2 miles; turn right onto Cunningham. The meeting room is in the terminal at the end of the road. A typical meeting of the SJEVA is casual and informative. A round table is held after chapter business is completed. Topics are typically very technical from the folks who are building and driving real world electric vehicles today. Come attend a free EVA meeting and learn from EVA members who have been building and driving Electric Vehicles for 50 years. Become a San Jose EAA Member of our nonprofit organization and Show Your Support for a cleaner public transportation option. George Stuckert Secretary, SJEVA |
