Spot on for recognising dual function that an energy storage could serve within the grid system (locations of where these batteries are placed along the grid transmission are important) : 1) To Prevent Congestion or Curtailment ; Usually placed close to source of generation, >10hrs of energy storage duration req'd, This battery could register more carbon offset value than the other one. 2) To Balance Electricity Market ; Cushion out negative prices, <10hrs of energy storage duration is sufficient, This battery help traders bid & respond more accurately on half hourly basis to avoid penalty of liquidity deliverable misses. Seems like LDES market potentials are growing as we understand more of its possible functions.

Would be more interesting if at least some tough questions were asked, like at 6:00: so just like that they just decided to build their own cells? Isn’t that a bit naive? And later… Based in Istanbul, OK, does currency devaluation not weaken their business?

well done thank you.

Host, You got a such lovely and sounding voice. I love it..

This is a great podcast! This is a right dose for any one that wants to understand the current energy market and still being able to understand every little detail. Worth it!!

You're right, Wind Turbine renewables has no Short Run Marginal Cost. Thus electricity sold via wind generation ought to Break-Even quicker (to R.o.I. profit level) than any other source of electricity generations. You guys are lucky to have a Renewable Energy 'buffet table' nearby like the North Sea, and by Merit Order wind renewables should be deployed first to customers prior to other source of electricity generations.

I work for a QSE in ERCOT and enjoy watching your videos. Well explained and informative. This is probably the first TH-cam channel out there where the average people that not involved in the energy sector can learn how an energy grid works. I am going to direct a new hire at our company to watch your ERCOT series.

Super awesome and informative. Much appreciated ! It would be super cool to get an overview on the Interconnection Agreement process in ERCOT and other markets

I’m new in the industry and this is very helpful to understand the workings. Thank you. Subscribed and will be waiting for more ercot material.

This is great!

This is great! Please keep this series going!

Modo Energy, You're awesome! Let's be friends and play together!

Thanks for the clear explanation 👍🏼 what would be the capacity and cost of such a battery to generate these revenues ? Thank you

Love this! Re 9:44, where can I learn more about the simplifications and assumptions to improve my understanding?

Thanks to both of you. Excellent review of existing and future trends in BESS.

Given this is aimed at absolute beginners, I feel a discussion along the lines of, 10MW for 2h and 5MW for 4h both result in 20MWh of consumption/generation, would have been useful.

Great series! I would like to see some more fleshed out videos on each of these topics though.

No update to this? I'd love to hear how they're doing vs the FTSE 100 😂😂😂

Can reduce the volume of music please

good vid though.

can you take a speach class please

your accent lost me mate.

How do you count the capex for augmentation of degraded batteries?

while i like Gore St, i still think theyre just the best of a bad bunch. Alex boasts about capital allocation but the reality is that they have 0 cash left over after the spending spree, just like every other UK BESS operator. so they dont have any money left to invest at these new better yields (and as the guy from Modo highlighted, this means all the BESS operators are now accepting yields far below payback and as Alex mentioned it means they cant raise more funds below NAV - pity this was not explored further, how are they going to grow without funding?). GSF spent all of the raised cash at lithum prices of around 6x today's prices - just like HEIT and GRID etc. Alex mentions that BESS has done a great deal for renewables but in truth its probably better to upgrade the grid before introducing so much BESS. if the grid were better connected/interconnected we would have more ability to export/import electricity between regions of a country. this would also allow for batteries to take better advantage of grid imbalances accross larger distances (scotland vs south/ west texas vs north texas). BESS operators should be working with national grid and other grid operators to expand grids (public private partnrships) thus allowing cascading increasing returns (better grids allow for BESS operators to capture arbitrage and imbalances accross larger distances but the grid expansion if paid for by BESS would also yield additional return from e.g. grid operators paying to use it - thats where some of the money should have gone, instead of all on expensive batteries). the BESS world is small minded and short term - they all pile into markets one after the other in a cascade of saturation, rather than actually proposing ways to invest into the grid or work with grid operators to actually make the grid stable long term. the real solution for renewable energy is nuclear, it provides a stable baseload and when you account for the costs of BESS + grid updates required for renewables - nuclear becomes cheaper (especially if nuclear buildout at scale). athough i like that GSF is diversified accross regions, new battery operators will enter all those regions and price out legcy operators like GSF over time unless GSF et. al. are able to raise more funds (assuming there is no other lithium price spike, bess systems will keep getting cheaper over time). fundamentally this is what is the biggest lie told by UK BESS operators - they had opportunities to scale back investment and allow for some capital preservation but every single one decided to continue with the complete investment plan. the worst thing is that there is 0 admission of this and it speaks to the type of people running the funds - after all, they are not accountable in any case - so why not tell the truth. Alex dances around NAV and seems to suggest its something other than a DCF (it isnt). the alternative to NAV he suggests is not really an alternative (using different revenue curves - which would be just another opinion). an alternative way to value GSF et. al. is to look at what price would these assets sell for in the private market - however Alex is far too intelligent to suggest any such alternative valuation methods. the hope is that massive renewable investment in ercot/CAISO keeps margins high in the usa. in the UK we wont have increasing revenues until interconnectors are in place (scotland to south) and some form of regional pricing is established (its absolutely rational for ESO to skip batteries since using batteries increases renewable penetration by tiny % while increasing costs substantially - for now). once these are in place, it makes sense for batteries to balance the grid and get paid for it since that would actually drive a significant increase in % renewables penetration. ireland will eventually move away from DS3 probably in 2027 and of course competition will increase - so revenues will certainly drop there since its not like ercot or CAISO where massive increases in renewable penetration are still to come online. all this can be used to calculate steady state values for the revenue curves, which are clearly still too optimistic (lets remove opinion from NAV and revenue curves - and use recent data and factual conclusions, and then maybe the GSF anagement fees would be worth the money). Long term i believe the picture is actually great (2030 onwards) because of larger energy demands (ai, datacenters) and expanded renewables/grids. However the spoils may go to companies starting up in 2028 rather than the likes of GSF (assuming battery energy stoprage is even long term viable). the big hope is that rates go down or GSF can somehow fund new projects (e.g. in partnership with pension funds or similar) but pension funds may not like the volatile nature of bess revnues. so its now up to Alex and co to show how good they are at managing capital and investment going forward. I do believe that he is capable of that and of attracting more investment for new projects and thats why i do own some shares.

Imagine ERCOT as a vast and intricate web of corruption and bribes, ensuring our owners can make a few percent extra profit by not spending money on pointless things, like grid resilience, cold weather protection, or interconnection standards. So what if it sometimes kills a lot of people? We'll just blame windmills, and then put out a meaningless youtube video complaining about how hard our job is, and how the repeated failures of our own network are definitely not our fault, and its so mean and unfair when people hold us accountable for our wilful negligence. This situation was brought to you by Corporate Greed, Science Denial, Republican Politicians, and Voters like you...

Looking forward to this. Thanks Brandt

This sounds nuts. I'm going to see what the latest status is. Why wouldn't Morocco just connect southern Europe (i.e. Spain). There's interconnectors within Europe (Viking Link is the newest for the UK, I think)

Good post and what a shame there are so few views. I am a Rippler if that’s a thing? Sarah strikes me as genuine and on a mission! Thank you.

Simply superb

This series is really helpful. Electricty markets are quite complex, and your explanation is quite simple. Thank you.

This is making electricity production more expensive so that makes it less efficient.

Wow, great Podcast. Interesting insight on developing such a project. Thanks

Another really brilliant podcast, it is great to hear about the complexities and challenges from the different markets. On the podcast series so far, in terms of flow battery systems, we have had talks with Vanadium and Zinc Bromide flow system providers. Would it be possible to hear from ESS inc? They have a an Iron Salt based technology, potentially I have missed this talk if it has already been done, but it would be interesting to hear further about this technology in the US market. Thank you

Thanks for a great interview, we're setting up a community owned 5MW solar farm here in Ireland so it was great to hear about Ripple Energy which has given us a good few tips and some inspiration🙂

Thanks for sharing! Would love to see more ! ❤

So informative, thx for this. Please keep it going

Gravitricity concept to store energy and use the energy for greed stability is a great idea or let say it is great project because the demonstration concept has proved 80% efficiency on energy regeneration. If the project will be designed for 500 tonne heavy body and shaft 600 m deep then potential energy stored on heavy body is 0.8175 MWh which with 80% efficiency will deliver on the greed only 0.654 MWh (probably on 11 sec or more if the system will be slowed. t=SQRT(h*2/g)). If the heavy body 500 tonne will be lifted again from the shaft, the energy needed is 0.981 MWh accepting the efficiency 80%. So Graviticity projects indeed are only to stabilize the greed to avoid any blackout. As can be seen from data if gravitricity will be used multiple time, then the lifting will get more energy from the greed, probably will get 1.5 time more energy than will return to the greed. As for energy storing underground on mine shafts using green H2, this technically may be achieved, and 100 tonne H2 on a shaft 9 m diameter and 600 m deep the hydrogen must be compressed 30 times, so it is possible if the shaft will be hermetic. However to produce these 100 tonne H2 at least will be used 5.5 GWh green electricity. If green H2 will be used to regenerate electricity for consumers, it is probable that 1.47 GWh electricity will be produced, so efficiency is 27% or lower. If investors will be happy with these ball point estimates this will save some renewable energies, but the cost will be very high. Real solution on solving energy security and abundance is Gravity potential energy combined with Levitation which can use multiple times the heavy solid blocks during the day. On these case a solid block 500 tonne at 600 meter high may be lifted 100 times during 24 hr and generate 65 MWh or more every day. A demonstration model for levitation-gravity energy generation (garage model) after proved the concept is destroyed for security reasons. No intention to file for Patents, but possible partner with government and strategic investors.

thanks for the 'explanation'. i understand 'everything' now

In this instance I can see why the battery storage can be disadvantaged during high renewable output. In this video co-location is both the solar asset and battery asset sharing the grid connection, with the graphic only showing export from each. But coordination between both assets, eg. an additional DC coupling to the storage could still bring favourable gains? Eg. 1.Time shifting 2.Coordinating grid load balancing, absorb excess solar. 3. Storage partake in ancillary services 4. Coordinating market participation. Does Modo see less collaboration for single grid connection projects resulting in fewer returns? Should there be coordination between renewable generators and storage in this space? Or is there regulatory issues hindering this in the UK? Eg. Metering complexity. Thank you
