The Issue

Our primary data source for cost data is the NREL ATB. We supplement this with pypsa/technology-data generated for a specific investment year. These data sources are not consistent with what year their units are in.

The ATB is given in 2021 USD, while the technology-data will adjust for inflation and give it in monetary units for that year (ie. 2030 EUR). Note, we do convert to USD.

We should ensure that all costs are given in the same monetary unit years. Most data right now is coming from ATB, so its probably not a huge deal. But something to correct if we start pulling more data from technology-data.
