"Einde salderingsregeling" 2 seperate cost calculations?

[infoed]

As of 1-1-2027 there will be no more salderingsregeling.
Meaning that I need 2 different costpricing /calculations since I have solar panels:
- 1 for calculating used energy (epex+energytax+commision * VAT)
- 1 for calculating returned energy(only epex excl VAT).

There's now only one price device available for electricity calculations on a dynamic contract.

IMO adding an extra custom sensor device in the meter/counter settings would be the best solution.
And some calculation method that uses that price only if the P1 meter is negativ ...?

What are the Domoticz plans?

When not having a dynamic tariff contract you can use the P1 fixed tariffs for Usage(T1 or T2) and Return (R1 or R2)

Do you have more info about the calculation on the returned energy tariffs on the dynamic contracts?

[infoed]

Check, on a fixed contract one can use the fixed pricing fields in the settings menu, as provided in the contract.

I don't know how the calculations work with a fixed contract after 1-1-2027, but I assume that they are the same :
- usage tariff = net. provider (fixed or dynamic) + commission + energytax * tax
- generate tariff = ONLY net. provider (fixed or dynamic)

So:
- usage : the all-in tariff
- generated : only net. provider , no VAT. ("kaal tarief")

So, IMO, on a dynamic contract, every hour/quarter o.a.h, when you generate (P1 is negativ) you need a second tariff: not the all-in one, but the "kaal tarief".
The generated tariff should only contain the EPEX on that hour/quarter o.a.h, without TAX.

There's also a thing called minimum return fee ("minimale terugleververgoeding")
Until 2030, this minimum tariff must be at least 50% of the net. provider rate. This is the electricity rate excluding energy tax and VAT. Roughly speaking, this currently often amounts to about €0.05 to €0.06 per kWh.
How to take this into account...?

Ps: maybe this effects the enever plugin, too.

But, I'm not an expert in this, my source is AI Maybe other forum members are?

With Zonneplan, you receive the same all-in price for exported electricity as you pay for consumed electricity, as long as the exported volume falls within the Dutch annual net-metering allowance. Any net surplus is compensated without the energy-tax component. In addition, exports between sunrise and sunset receive €0.02/kWh plus 10% Zonnebonus when the market price is positive, up to 7,500 kWh per calendar year.

I guess you are forgetting the 'energie belasting' for consuming......

Energy tax is included through the Dutch net-metering scheme: until the end of 2026, energy tax on exported electricity is offset against energy tax on consumed electricity, up to your total annual consumption. So within that limit, the all-in import and export price is effectively the same. Only net exports above annual consumption don’t receive the energy-tax component. From 2027, when net metering ends, that distinction will indeed become important.
