Help with Nordpool and correct configuration/value

I tried adding nordpool to my setup but can’t get the price correctly.

I have created a template that include “VAT” (what I think at least).

But it won’t work, someone knows what I’m doing wrong or missing?

Template:

{{ ((states('sensor.nord_pool_se3_aktuellt_pris') | float(0)) + 0.53) | round(2, default=0) }}
type: custom:apexcharts-card
header:
  title: Energy price today (SEK/kWh)
  show: true
  show_states: true
  colorize_states: true
span:
  start: day
now:
  show: true
  label: Now
series:
  - entity: sensor.nordpool_sek_aktuellt_pris_template
    name: Aktuellt
    data_generator: ""
  - entity: sensor.nordpool_sek_peek_lowest_template
    name: Lägsta
    type: column
    data_generator: ""
  - entity: sensor.nordpool_sek_peek_high_template
    name: Högsta
