Hi @tfedyna!
The first part is a question for @chriswmackey but I try my best. It depends on what do you mean by the annual load recipe. Is there a reason that you can’t use the annual energy use or custom energy use for this?
Everyone can push their recipes to Pollination under their account which makes it accessible to everyone on the platform. The way to do it is to set up a GitHub Action or run this command like this one directly:
Writing a whole recipe might be a major undertaking. If you can modify one of the existing recipes that will be a much easier starting point.
