data.fetch_data.load_timeseries

data.fetch_data.load_timeseries(data_home=None)

Load the actual-load time series from interim/energy_load.csv. Reads the Actual Load column, converts the index to a UTC DatetimeIndex with hourly frequency, and fills any missing values with forward/backward fill.

Parameters

Name	Type	Description	Default
data_home	Optional[Union[str, Path]]	Root data directory. If None, resolved via `get_data_home()`.	`None`

Returns

Name	Type	Description
	pd.Series	pd.Series: Hourly actual-load series indexed by UTC timestamps.

Raises

Name	Type	Description
	FileNotFoundError	If `interim/energy_load.csv` does not exist.
