The surge management problem is an interesting challenge. One million batteries all starting to charge at 5kW is a 5GW load. IIRC, the Dinorwig pumped storage power station can produce 1.8GW in less than 10 seconds if the turbines are already spinning in air at the operating speed. The surge problem can also be mitigated by requiring the battery manufacturers to modify their software to ramp up the charging over several minutes so the generating system has more opportunity to respond. This might be easier than fiddling around with offsets which could result in batteries being out of synch with meters.

@editor DESNZ are extremely eager for Suppliers to directly link EV Tariffs to the presence of a Smart Charger.

For example, I can use Octopus Go without having a Smart Charger,
but when switching to Intelligent Octopus Go, I have to link my charger (and model of car) to Octopus via an App.

It's because that particular Octopus has a higher IQ, of course.
Their website says it can understand 280 different types of car... which is more than I can.

DESNZ are modelling the forthcoming Demand Side Response remote control of Heat Pumps on the data they've gleaned from Smart Chargers.

Here's a relevant paragraph from the Executive Summary to the Delivering a Smart and Secure Electricity System (April/May'24)

It will become a national energy consumption database.
Not only will it turn off household appliances as Demand approaches Supply, but it will issue instructions to NESO and the Power Generators to increase output.

Because the software will know which tariff we're on, it can forecast when to turn on particular power sources.
It's an all-knowing, all-seeing energy control system

Shall we call it Beyond Horizon?

This is insane!

What happens when it breaks down (because it will)?

What happens when it gets hacked (because it will)?

What happens when working as it should it turns off your cooker when you are half way through cooking a meal?

It'll be fine @cathoderay 

DESNZ went out to consultation on it.
It's firmly founded on the feedback from the thirty of us who bothered to respond.

Just looked at the rates for the Go tariff and will have to do another exercise based on 19 hours without cheap access to the grid. It would certainly work for me out of the heating season! Rewards, Toodles.

Received an email today from British Gas informing me that I had saved the princely sum of £2.36 in November from using their cheap Sunday electricity.

I’d be interested to hear the feedback and consensus on the tariffs we discussed recently and if you agree:
