Energy rate from Nordpool spot price

[johanzander]

I'd like batpred to derive my import / export energy rates from Nordpool spot prices. I believe this is a common scenario for users in Scandinavia with variable energy tariffs. Personally I use Tibber who only add a markup on the hourly Nordpool spot price.

One could use the Nordpool API directly, or use the HACS Nordpool integration which gives a neat sensor that could be used directly in batpred. In either case one would need to select area (e.g. 'SE4') and currency (e.g. SEK).

My actual rates would be : Import rate: ((Nordpool spot price for SE4 in SEK) + Tibber 0.08 SEK markup) * 25% VAT + 1.03 SEK (fixed cost to grid owner + tax). Export rate: (Nordpool spot price for SE4 in SEK) + 0.6518 SEK (tax subsidies)

Can this be achieved today in batpred? Otherwise, consider this a feature request :-).
