Westeros tutorials inconsistent with changes made to baseline

[OFR-IIASA]

Recent changes to the Westeros baseline scenario have resulted in inconsistencies with scenarios building off of the baseline:

• westeros baseline:

  • See also issue technical_lifetime not defined for historical vintages in Westeros tutorial #609 -> when completed, remove addition of capacity_factor in westeros_historical_new_capacity.ipynb

• westeros_historical_new_capacity.ipynb

  • Change baseyear demand = 100GWa
  • Change text above the definition of demand to match
  • Remove FOM cost to comparison of gas_ppl and coal_ppl - for demonstration purposes.
  • Adapt "i.e. as we haven't defined fixed operating and maintenance costs."

Shifted due to prioritization of ENGAGE baseline unit issue.

As noted by @khaeru on Slack,

Both the coffee machine and Westeros baseline tutorials are using from message_ix.util import make_df. This function is provided at the top level; we can show instead from message_ix import make_df.

Whenever we get around to overhauling the tutorials, this should be included.

Postponed due to lack of capacity/urgency.

Another thing that I think could be improved here:

• Many of the tutorials have a "dependency" on westeros_baseline.ipynb, in the sense that the user must first run through that tutorial in order to have the baseline scenario in their local database expected by a second tutorial.
• This both:
  • Increases friction to jump directly in to particular topics (if the user wants to do that, and we want to support it).
  • Complicates testing, as we have to be sure to always run westeros_baseline.ipynb first and ensure its output is present.
• We already have message_ix.testing.make_westeros() that does (and should always) produce the same scenario as the baseline tutorial.
• So, I would suggest we could add 1 cell at the top of many tutorials like:

  if westeros_baseline_is_not_present:
      make_westeros(mp, ...)
