EDITED QUESTION to add context:
I'm interested in "modeling" the Electricity Price for Residential Users in the US, particularly (if possible) in Massachusetts.
I'd like to obtain something like a 24 hourly-prices list for every day of the year.
To relax this constraint, I could also accept a list of 24 hourly-prices per month, or even just per season.
And, to relax even more, I could also accept a resolution greater than 1 hour. E.g.: resolution = 4 hours: so, instead of having a price for each hour of the day, I could accept a single price for an interval of 4 hours (so 6 prices per day).
So, I'm looking for something similar to the dataset of this link: https://data.open-power-system-data.org/time_series/2020-10-06. It consists of a CSV file which collects hourly electricity prices 32 European countries, but I'm interested in the US.
Another way could also be to find scientific papers (or other sources) which model the electricity price associated to every hour of the day (this time interval could be relaxed) in the US as a PDF, by providing the 'mean' and the 'standard deviation' (or any other parameter which describe the PDF).
Is there anyone who knows any reference (papers, dataset, link, ...) which could be useful?
