Power to heat: Input, curves, merit order subtype, initial updates (#3335)

louispt1 · noracato · mabijkerk · web-flow · commit 89e5505d8d30 · 2025-10-31T10:28:23.000+01:00
* Update merit order subtupe and temperature_cutoff for p2h nodes

* Add p2h curves and temperature_cutoff input

* Queries for chart and minor adjustments to nodes and input for p2h tech

* Add initial update to set uploaded availability curves for temp based p2h

* Update curves and intial updates to match

* Set availability to 1.0 for temperature-dependent p2h

The availability is overwritten by the temperature-dependent behaviour and therefore has no actual effect.

* Add a comment explaining the initial updates input for temperature based p2h

* Expand comment on initial updates file

* Update atlas reference
