All the required files seem correct and the commit messages are generally clear. However, for quite some values it is difficult or not possible to trace how the value is determined.

For example:

- fields:
  - input_energy_chp_ultra_supercritical_ht_lignite_production
  message:
    "Derived from the energy balance (2019)."

- fields:
  - input_energy_chp_local_engine_ht_network_gas_production
  message:
    "Derived from the SEAI energy balance (2019). Natural gas input for CHP plants: 264 ktoe."

Even though the source is provided, I can't trace it back easily. That is why we often create a source analysis file (excel) on ETDataset where users or contributors can trace back exactly how the data is determined. See for example the source analysis folder for Norway.

Could you add a source analysis file for Northern Ireland that contains the updated keys and gives insight in the calculations, where relevant, and the table exports (e.g. of energy balance values or Eurostat tables).
