Constant PV power production price:

0,03
The paid price for energy injected to the grid from excess PV production in currency/kWh.

[Blizzeq]

The runtime key is prod_price_forecast, not production_price_forecast. Your log shows the payload with 'production_price_forecast': [...]. EMHASS doesn't know that name, drops it without a warning and keeps the constant method, so unit_prod_price stays at photovoltaic_production_sell_price (0.03).

I ran your payload through 0.18.1: as posted I get 0.03 on every step, with only the key renamed the first step is 0.14423. The accepted keys are listed in passing_data.md.
