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

@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

@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?

@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.

@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.

@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.

M1SJE - QRT From Xitter
@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.

@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 😀
