Simulating Flanders - PV + Battery Incentives was created by yashagarwala

Hi,

An international user here. I am trying to a PV+battery system for the best payback period based on the recent incentives announced in Belgium - Flanders for the year 2021. It consists of 3 components:

1. Feed-in Tariff (Injection Price): 3.5 cts/kWh - This is believe if I use the net billing scheme and set the selling price to this then I am set.
2. Direct Cash Incentive for the PV system capacity: 300 Euros/kWp for <= 4 kWp and then from 4 kWp to <= 6kWp 150 Euros/kWp | I do not seem to be able to feed in such a staggered incentive scheme. Any suggestions here? I could probably take an average but that will not capture the difference between the 4 kWp and the 6kWp price drop.
3. Direct Cash incentive for the Battery Capacity: 250 Euros/kWh with a MAX at 3200 Euros | This I have no idea how to incorporate. Please help?

Looking forward to your suggestions here.

Kind Regards,
Yash Agarwala.

Hi Yash,

1. Keep in mind the treatment of excess generation for the net billing option -- you can read how that is handled in the Help description.

2. You would have to calculate the total incentive amount by hand, and then use one of the IBI "Amount" categories to represent the incentive. You can ignore the category names in SAM: Federal, State, Utility, and Other -- you could use any category to represent the payment.

3. The "Capacity Based Incentive" in SAM is based on the PV array capacity rather than the battery capacity, so you would have to calculate the value of the cash payment by hand as in #2.

Best regards,
Paul.

Hi Paul,

Thank you for the reply. I will read help for the #1.

I understand what you are saying about #2 and #3, however, my goal is to try and simulate scenarios by varying the PV system size and battery size to see where the best Payback period sits. And if I can't make it related to these values in some way then while performing the parametric analysis these incentives will not be properly captured in Payback period calculation.

Any way to make this happen?

Appreciate your time.

Kind Regards,
Yash.

Hi Yash,

If you have some knowledge of computer programming or scripting language, you could use SAM's LK scripting language to write a script that would calculate the incentive values, set the appropriate inputs, run a simulation, and get metrics of interest from the results, and write them to a text file or display them.

See sam.nrel.gov/lk-script.html.

Best regards,
Paul.
