why did I watch this.

Thanks for making this video! Very helpful for my job

this video explains exactly zero. just a bunch of yappin.

The amount of fossil fuels used to create these battery farms outweighs the “4hrs” of peak demand. Liberals never cease to amaze me. As long as you feel good then it’s ok? This is worse for the environment than the old fashion was.

Cable failures are nothing to do with batteries.

100 megawatts is useless. We are talking Gigawatts a thousand times more.

Presumably the battery cost will be included in the overall cost of electricity.

His is all to cover the elec part of energy. This is 20%. What supplies the grid in2050 when fossilfuels are cancelled. This will probably quadruple the demand for elec. How much have they paid for these batteries. Engineers calculated USA would be £350 trillion by 2050.. So how much is covered and how long doesit last 4 hours ?

Thank you CAISO to illustrate all this oversupply issues!

Very informative conversation. Great job CAISO Operations team!

This update offers valuable insights on enhancing the operational tools needed to manage California's modern high-voltage grid. Throughout my 37-year career in Power System Operations, I have always advocated for real-time, actionable information that System Operators can utilize to maintain situational awareness. If your team requires additional assistance in developing future tools, please don't hesitate to reach out. I am available to help in any capacity.

You need how many megawatts to power all the housing units in California exactly? Does 15,000,000 MWh a day or 450,000,000 MWh a month sound relatively close? Also how green is that really?

Using a multiplier of 1.0 ensures the resource will be able to dispatch for day ahead awards. We reduce the multiplier to be more realistic and avoid being overly-restrictive. W/ the 1.0 multiplier you are limiting the max total reg awards to the duration of the battery - i.e. a 4 hour battery could never win more than 4 hours of REG (e.g. 2 RU + 2 RD if the battery starts at 50% SOC). max duration of DA REG awards = battery duration / multiplier Since hitting these envelope bookends precludes the battery from any further energy awards. One would imagine that this would encourage resources to seek energy awards earlier in the day, and reg awards later in the day. This would allow for the greatest total awards in the DAM. If a 4 hour battery is awarded 4 hours of REG early in the day, it cannot be awarded energy for the remainder of the day. If the resource is awarded 4 hours of REG awards at the end of the day, this methodology woult not restrict energy awards. The PG&E solution, while less restrictive could also create a situation where there battery cannot recieve any awards if SOCat is at the maximum bound AND SOCen is at the minimum bound. Should Reg Down awards increase the lower SOC bound and vice versa, making the bounds less restrictive. These adjustments could perhaps be made with a lower multiplier. Reg Down awards would increase the ability to later be awarded Reg Up awards and vice versa - though not on a one for one basis perhaps. It would make sense to reduce the restrictiveness by restoring a portion of the envelope each interval. For example, for the 100MW/400MWh battery, each hour the SOC_U is decreased by 25MWh and SOC_L is increased by 25MWh. This would serve to keep the battery in the game while keeping the total DA awards manageable. Optimal Strategy: Use a single envelope-style constraint, but with more flexibility than the CAISO proposal: - The SOC_U should include a REG_U factor w/ a reduced attenuation factor to add flexibility and vice versa w/ SOC_L and REG_D. This allows the REG awards to offset each other as in the PG&E SOCat equation, but reduced coefficients to account for the uncertainty. - Reduce the contraints by some amount each interval as described in the previous paragraph. This strategy: - Accounts for movement in both directions due to REG - Builds in some uncertainty for deployment - Allows the resources to receive DAM dispatch awards throughout the day - Reduces likelihood of too many awards in the same direction in an unmanageable time frame. We would need to optimize: 1) the REG attenuation factors that tighten and loosen the SOC_L and SOC_U constraints 2) the factor by which the constraints are loosened each interval to give back flexibility over time SOC_U(n) = SOC_U(n-1) - (energy discharged) + (round trip * energy charged) + A*(reg down) - B*(reg up)- (X) SOC_L(n) = SOC_L(n-1) - (energy discharged) + (round trip * energy charged) + C*(reg down) - D*(reg up) + (Y) where: A > B and D > C X and Y are both some fraction of the battery energy (probably proportional to the power rating of the energy storage system) A, B, C, D, X, and Y are all coefficients that should be optimized to balance flexibility and confidence that awards can be practically met.

Is the footprint map available to the public?

Have you ever heard about the dreams of Muhammad Qasim from Pakistan. In his dreams he was shown to be a leader in Pakistan. Some ordinary Muslims from various nations around the world also had a dream that this Qasim is Imam Mahdi. What do you think about this news?

Good info

Excellent presentation by Sirajul Chowdhury. Thanks

Excellent presentation CISO.

Can i get the excel pls

One of the worst presentations I have seen..

*Promosm* 😞

Now a year later, double the capacity at 5,600MWh. Bravo

I feel like Gabe didn't answer JP's question. What if the battery is fully charged, and one wants to bid Reg Up? You would not be able to bid 50% of the Reg Up award in the charge direction, because the battery is full. So you can't bid for Reg Up when your battery is full?

California fornication? Cesspool of drugs, homeless, bank failures, and can't even put a high speed rail like China? Total GRID Lock Society? 🤔💰💰💰💰💰💰💰💰💰💰💰💰💰💰💰💰💰

There is no climate chrisus. It is a pile of lies.

Very informative. Thanks for the updates.

Is home roof-top solar included in the solar stats? How much roof-top solar is installed in CA?

Thanks for the information ℹ️

How do you trade amd make money with this

Letha Tawney voted to raise rates 15%

good tie-in to the story of Enron!

At minute 35:45, the demand should be vertical.

...Dr Aldrete provides an important update and makes a great attempt at verbally explaining the details. I plan to listen to the complete presentation from a large customer segment point of view in their relationship with the Scheduling Coordinator (the IOUs) which also now plays a role as the Central Procurement Entity.

Way to say nothing whilst talking for a whole 90 seconds

A virtual grid will also play a big part.

...Great presentation. The presenter breaks down the complex into simple parts. Briefly cites the meaning of each acronym in common terms. Easily understandable

...Another great session. For those familiar with Mr. Scott Garvey, once again Mr. Harvey brings up excellent points throughout the session. In my opinion in working with real front line large customers, Scott Harvey is a voice of reason in the Market Surveillance Committee of what happens in the "real markets" especially when CAISO is in an EAA2 scarcity event. Finally, the PowerEx people always provide great observations on Western Energy Imbalance Markets and the Hour-Ahead Scheduling Process (HASP) which is a process for scheduling Energy and AS based on the Bids submitted into the from Scheduling Points.

I really enjoy listening to PowerEx (Mark Holman). The PowerEx guys are very experienced in the power markets across many Balancing Authorities (BA).

...The CAISO SVP/COO is making great common sense when he discussed let's not let any "hold backs" constrain what's occurring in the real time markets.

I find it amusing that 'California ISO' is located near Folsom Prison. Presumably so the State of California would have enough electricity to power their 'Electric Chair' executions ! So see, there really is some logic to their business !

..Today' August 9th Media Briefing by CAISO. President CEO Elliot Mainzer is very open and transparent. He talks about variable energy resources and the role of storage, Demand Response, Flex Alerts etc. The Utility Account Managers across California play a role in being on the "front lines" supporting and communicating out to real customers. Everyone is learning and working together. My take is the outcome will show that California once again at the leading edge. Imagine a future of "Automated Demand Response initiatives" connecting and integrating thousands of buildings to really help the grid/CAISO.

.. This is an excellent update from CAISO Elliot Mainzer on the Heat Storm that occurred week of Sept 5th through Sept 9th. On Sept 7th, an all time record grid demand of 52,000 MW took place.

Informative update from CASIO. The questions from the media demonstrates they probably need training on the role and methodologies of the California Independent System Operator (the Balancing Authority), the Scheduling Coordinators ( the utilities), the Public Utilities Commission, and the California Energy Commission, including integration across the "Western Imbalance Market aka WEIM". However, I understand because over the years I spent many hours listening to CASIO, EIM, Western videos on this channel. Also took myself to CAISO training.

Can you please describe what an RA credit is in more detail?

Ban air conditioning it’s the only way……,and leather shoes. Lol

Good training albeit I was surprised to hear the trainer say "ya know" almost every other sentence. I heard in a Speaker's Bureau it's best for presenters to refrain from using the "ya know" in a presentation because it interrupts the flow and momentum of a training session or speech.. It takes lots of practice in delivery.

@minute 40:00 interesting discussion initiated by Mike M of CES on "Co-Located Facility" and frequency of mitigation on impacts of State of Charge (SOC) that perhaps conflict when the SOC is really needed. Reading the transcript.

While Nancy Skinner's intentions were/are good, but the simple fact is that none of this would have happened were it not for the reduction in the cost of panels and batteries....and the involvement of Tesla. Odd that Tesla isn't mentioned once in this piece.
