Calibrating the electricity generation data

[nurf004]

Dear GCAM colleagues,

Anyone has an experience to recalibrate electricity generation using bottom-up data (e.g., electricity generation from coal-fired power plants)? I find difficulties to match the GCAM data with the current trend as I'm planning to update the energy data for 2020.

Thank you in advance.

We did this for a project a few years ago, for the USA region; not sure if this is what you're looking for, but the file basically tunes the output of coal-fired generation in the 2020 and 2025 time periods to roughly match recent data and expectations. Looks like I can't attach an XML file here, so just copying it. This could be tuned or modified for different regions.

@pkyle thank you for your response. I have seen this file, but I have no idea with the categorization of <stub-technology name=..> . I mean how I assign the value (steepness and life) for each category while the data I have is electricity generation (TWh) and installed capacity (MW). This is the reference that I am intended to adopt https://www.nature.com/articles/s41467-019-12618-3. Also, what about the technology (i.e., coal (conv pulv, IGCC), gas (CC, Steam/CT)? Is there any xml file that should be added? Thank you very much.
