@Seb_smartEn @smartEnEU Jup, thats me.

@PieterOmtzigt Ik stel een nieuwe paas traditie voor. Het aanzetten van alle lampen in de kassen als de zon schijnt om het overschot aan zon tegen (forse) betaling weg te regelen. Harstikke duur(zaam) en groot succes gister!

@KimCJorgensen @GraduatedBen Not 230v? Damn, early mover to LED!

🔋⚡️ Je elektrische auto slim laden, d.w.z. laden op basis van dynamische energieprijzen zodat je goedkoper en duurzamer je auto oplaadt.

Dat wil je. Want de impact van de elektrische auto op de stroomrekening is groot.

Maak veel e-rijders krijgen het niet voor elkaar. Een 🧵

Anyone with a Zaptec charger can now smart charge to save CO2 and money. Wanna charge on cheapest hourly rates or during your own solar pv generation?

@FrankVisserMSc @StekkerApp Kun je even contact met me opnemen via [email protected]? Dan kan ik je verder helpen.

@FrankVisserMSc @StekkerApp Hoi Frank, wat vervelend om te horen dat het niet lukt. We weten dat er allerlei verschillende versies van de e-Niro zijn en dat sommige zonder connectie niet werken. Is de E-Niro op dit moment zichtbaar in de UVO app en kun je daar het batterij % zien?

[Erik van Boekel @erik_boekel]

@KevinSchoormans Laden is duurder dan benzine. Als je dit slim doet met het juiste energie contract ben je ook nu nog veel goedkoper uit.

@robertvg In Germany most curtailment is capacity based. However it seems (im still validating) to not be based on actual grid status but on standard rules like x % feed in max for smaller PV installations. Still researching this.

[Erik van Boekel @erik_boekel]

How to save actual CO2 with EV charging? By charging to avoid #curtailment of wind & solar.

Curtailment: "the deliberate reduction in output below what could have been produced in order to balance energy supply."

In other words wasting wind & solar energy..

[Erik van Boekel @erik_boekel]

@robertvg On average this is the case 10-15% (regulation state -1 and a negative price) of the time. However this is not spread evenly. It occurs much more during solar hours.

[Erik van Boekel @erik_boekel]

@robertvg In example in the Netherlands Solar will already be curtailed on a regular basis if the DAM (day ahead market) turns out negative priced for multiple hours. In addition every time the PTU (15 minute window) turns negative dynamic managed solar will also be turned off.

[Erik van Boekel @erik_boekel]

@robertvg Good question. It depends on the region I am not sure what the overall main reason would be. In most US regions its local congestion, Netherlands economic, this is not per se the same as misjudgement.

[Erik van Boekel @erik_boekel]

I think it makes sense as a habit postpone charging as much as you can to the weekend CO2 wise. Going to look into it. Will tweet outcome.

[Erik van Boekel @erik_boekel]

Anyone in Germany/Austria using #aWATTar and charges their EV @ home? Looking for a tester!

[Erik van Boekel @erik_boekel]

The cheap electricity prices in Norway are back (NO3). Machine learning didn't see that coming :).

[Erik van Boekel @erik_boekel]

@greg16676935420 To me it means either birds per second (meyn foodprocessing) or balls per second (paintball).

[Erik van Boekel @erik_boekel]

@lks_kln This is because most people don't have 11 kW of solar production on their home but do charge at 11 kW. But it makes sense to charge then. There are many other solar-pv people also ingesting in the grid.

[Erik van Boekel @erik_boekel]

I read that in Germany 2.3% of total renewable was curtailed in 2016. Does anyone have more recent figures? #curtailment #smartcharging

[Erik van Boekel @erik_boekel]

@lks_kln If you drive lets say more then 15k per year im convinced it would be cheapest for you to be on these rates. You will earn a bit less with solar because these hours are cheaper priced but then again if you charge the car then this usually is a good trade off.

[Erik van Boekel @erik_boekel]

@lks_kln I know suppliers in germany are also is starting to move to these products like for example:

[Erik van Boekel @erik_boekel]

@lks_kln So basically there is two things:
1. Save money on your energy bill & CO2 by charging on dynamic tariffs.
2. Help balance the grid by shortly starting or stopping charging.

The first one is getting more common now but still a little group (>5% of households). 2nd just starting.
