Maybe if you'd asked the question @guardian 🤣

We have no idea where The Guardian got this from. It is absolutely wrong. British Gas do not use Kraken.

@StemShow @M1SJE @krakentech @OctopusEnergy @g__j @StemShow it may be sooner than you think. With EVs alone, we went from 600 cars to 115k in under 2 years, that's almost a GW of power spread across the edge of the network. Pretty powerful tool for managing grid stability.

@M1SJE @dcelal @krakentech @OctopusEnergy @g__j I just can't see small scale input as a reliable method of ensuring grid stability. Not yet. It's a great idea and totally possible but focusing on getting some large scale back up sorted is prob easier than coordinating with small scale first imo.

@krakentech keeping lights on💡during Christmas 🎄 👉🏼 Today, the power line ⚡️connecting UK 🇬🇧 & France 🇫🇷 tripped 👉🏼 Within a sec, UK lost 1GW (1m homes 🏡 worth) Kraken 🐙 in <1 generated 400MW ⚡️from batteries 🔋 on the platform, keeping the lights on 💡 @OctopusEnergy

@Grumpybeeman @krakentech @OctopusEnergy @krakentech_ Hi @Grumpybeeman, we have been since 2017. dashboard.krakenflex.com These batteries are owned by @krakentech_ customers.

@bexcran @krakentech @OctopusEnergy Whoops @krakentech_ , the correct one

@staustellsimon @nickshanks_ @M1SJE @krakentech @OctopusEnergy @g__j @krakentech_ That's part of the reason, it also allows us to monitor power (and other metrics) in real-time to validate our actions from a certified meter.

@TheJAMF @krakentech @OctopusEnergy -400MW on the graph is the cumulative export from the batteries, making up for part of the shortfall from losing the interconnector

@dcelal @krakentech @OctopusEnergy So if it hadn't responded, the dip in the graph would have been to -800MW? Or is the graph showing how the -400MW deficit was covered?

@olivercarlos91 @ClemCowton @krakentech @OctopusEnergy @olivercarlos91 @NationalGridESO buys these services in daily auctions from asset owners (typically batteries). Market prices would not have been fast enough to created the required outcome.

@dcelal @ClemCowton @krakentech @OctopusEnergy What are the economic incentives for the ess owner? Did prices also react that fast and did that trigger the backup power? What is the mechanism?

@jezyez @krakentech @OctopusEnergy I have not heard of a secondary trip or an outage. My suspicion is the batteries delivering different types of frequency regulation service (there are 3) getting activated over the period. But, worth a deeper look

@dcelal @krakentech @OctopusEnergy There seem to be 2 dips, one to ~49.7Hz and then to 49.3 Hz. Is the first dip the IFA trip and the second dip a result of generators tripping as a result of the frequency drop?

@IanHailey @krakentech @OctopusEnergy @IanHailey these were large grid connected batteries. In events like these, devices need to respond extremely fast. We have a sizeable portfolio of consumer devices, 115k and growing. They are great for shifting charging to match renewable generation and supporting networks.

@dcelal @krakentech @OctopusEnergy Are these residential batteries controlled by octopus?

@NoSheds @krakentech @OctopusEnergy Power generation and demand needs to be in balance every second of the day to maintain a 50Hz frequency which is the frequency that all our electrical and electronic equipment is designed to operate at. If there is oversupply, then the frequency goes up, or vice versa.

@staustellsimon @nickshanks_ @M1SJE @krakentech @OctopusEnergy @g__j 757 residential batteries that @krakentech_ can instruct to import and export, taking into account owner preferences, energy prices and network constraints

@nickshanks_ @M1SJE @krakentech @OctopusEnergy @g__j @nickshanks_ , we actually do, apparently 757 as of last night (dashboard.krakenflex.com). Admittedly, much less than EVs but growing.

@dcelal @M1SJE @krakentech @OctopusEnergy @g__j Kraken doesn't use residential batteries though, or does it? My battery is always available but afaik there is no tariff available that allows octopus to command it to dump to the grid. I'd be happy to allow that.

@M1SJE @krakentech @OctopusEnergy @g__j @M1SJE we need both. Big batteries are great at very fast response. They are highly available and fast when needed to stabilise the grid. Residential batteries are great. Better suited for balancing renewable generation and supporting the distribution grid.

@dcelal @krakentech @OctopusEnergy And this is why Octopus (@g__j) should be working on getting more non MCS battery ESS systems on the grid. Forget huge battery farms, what you want is 100,000+ small 5+ kWh batteries hooked up to the grid, ready to support the grid/country. My 16kWh battery stands ready.

#SavingSessions are just the beginning. @shocky100 , Octopus’s Head of Global Flexibility, and @dcelal, the CEO of KrakenFlex discuss the huge implications of saving sessions on a future flexible energy system 👉 open.spotify.com/episode/5MKx2s…

Depsys has joined @kraken_flex 🎉supercharging ⚡️our product. We can now 👀 deep into #LVnetwork ✅ manage faults ✅ monitor power quality ✅ model power flows This is critical to make #energytransition affordable, #griddigitalisation is 7️⃣0️⃣0️⃣ x cheaper 💸 than reinforcement

Great week at #enlit2022 with amazing #Kraken team. 🥇major international conference. ⚡ @g__j delivered a passionate keynote 🌟 Excellent panels by @lboogiebeers @MarciaPoletti ⭐️ I talked about role of tech in #FutureEnergySystem 💪 Great presence at venue & across Frankfurt

@AndrewRendel @kraken_flex @OctopusEnergy Hi @AndrewRendel, a number of different things coming together at the same time: 1. Growing installed base of EVs, large scale batteries, etc, 2. Higher penetration of renewables driving the requirement for more flexibility 3. Availability of tech that use 1 to deliver 2 😀

Major milestone for @kraken_flex 💪🏼. We can now power ⚡️ the #fluxcapacitor & send the #DeLorean #BacktotheFuture! Live 1⃣.2⃣1️⃣GWs including 1,000s of #EVs 🚗. Visit us at #Enlit stand 12.1.D162, to find out about our work to enable the #energytransition. @OctopusEnergy

@muppetkeeper @kraken_flex @OctopusEnergy Definitely, DM me pls so that I can put you in touch with the right person
