It's great, isn't it? I can see several benefits. It may simplify the installation (maybe just 120V?), but it can help manage the load, both as max load and as time-shifting, to hep in tariffs with dynamic rates (or strong TOU), and those with capacity charges Similar to a Copper stove

A modern battery that also does load management and that has those appliances connected/managed can do what you suggest if it needs to The ideal is to be able to do that when needed - long spikes - but even a relatively small battery by itself can just “smooth out” the spike

110

Eduardo Pelegri-Llopart @pelegri.bsky.social · 05/09/2025

A Dybamic Price mechanism is continuously compensating the owner of the resource directly. The challenge is finding a tariff that is understandable and that compensates well the homeowners. Both in managing the load and in exports IMHO, the enabler for Dybamic Rates are batteries and automation

110

Eduardo Pelegri-Llopart @pelegri.bsky.social · 05/09/2025

So they provide little compensation and are called when consumers are most likely to want the resources Another problem is that they pay little to the owner of the resource, the consumer And these make it harder to convince consumers to sign for the programs

Eduardo Pelegri-Llopart @pelegri.bsky.social · 05/09/2025

“VPP” is a fuzzy term. Ed is referring to a program like DGGS where aggregators are reacting to high demand events by managing resources they control There are several problems with those. One is that they are event-driven, not continuous. They are triggered by high load events…

The tariffs have 3 TOU bands: Peak, Partial Peak and OffPeak, with rates depending on max power The electrical bill includes data on both consumption and maximum power in each interval so customer knows what's happening and can adjust.

Eduardo Pelegri-Llopart @pelegri.bsky.social · 16/07/2025

It seems the transition could be improved. I know about Spain where Smart Meters became mandatory in 2018. There rates vary depending on the max power contracted. A household can change the contract online once a year - if the electrical setup allows. There may also be tariffs with different tiers

I did a quick check and it seems Australia has what is called here “demand charges”, I.e. per day charges based on maximum contracted power. So does Europe. The US only has it in a few utilities. I never understood why as it makes a lot of sense to me California has plain connection charges
