Error with FCAS

[KolinCunningham]

this is what I am running:

from nemosis import dynamic_data_compiler
import os

Define a small date range for testing

start_time = '2023/01/01 00:00:00'
end_time = '2023/01/01 23:59:59'
table = 'FCAS_4_SECOND'
raw_data_cache = '/Users/caesar/nemosis_data'

Ensure the cache directory exists

os.makedirs(raw_data_cache, exist_ok=True)

Fetch the FCAS data

print(f"Fetching FCAS data for {start_time} to {end_time}...")
fcas_data = dynamic_data_compiler(start_time, end_time, table, raw_data_cache)

Check if data was returned

if fcas_data.empty:
print("No FCAS data returned for the given period.")
else:
print(fcas_data.head())
# Optionally, save the data to CSV
output_file = '/Users/caesar/Desktop/Fcas/fcas_data.csv'
fcas_data.to_csv(output_file, index=False)
print(f"Data saved to {output_file}")

And I am getting error such as this (below). Does this mean the data set does not exist anymore?

: WARNING: FCAS_202312011625 not downloaded
WARNING: Loading data from /Users/caesar/nemosis_data/FCAS_202312011625.feather failed.

AMEO only keeps a recent set of FCAS data uploaded, so only the most couple of months of data is available. Check here to see what AEMO currently has uploaded: http://www.nemweb.com.au/Reports/Current/Causer_Pays/

There is also older set of files for complete years, but only up till 2017:
