pyaeso

pyaeso is a python package that makes access to the Alberta Electric System Operator's (AESO) Energy Trading System (ETS) easier.

The Alberta Electric Systems Operator (AESO) (http://www.aeso.ca) operates the Canadian province of Alberta's deregulated electricity market. AESO provides price, demand, and other valuable information through the publically accessible Energy Trading System (ETS) website (http://ets.aeso.ca). This information is useful for economic analysis, power trading, electric system study, and electric system forecasting. The first step in using such information is to download it and parse it into useful data structures - a task performed by this library. Typically the data will feed statistical methods, heuristics, and system models to provide useful analysis of the Alberta electric system.

Requirements

Installation

Extract the archive, enter the recovered directory and type:

python setup.py install

Usage

Some code samples that use pyaeso are availble in the ``examples`` directory. One sample is listed here::

'''Print yesterday's market clearing price/demand points and exit.'''

# Standard library imports
import sys
from StringIO import StringIO
import datetime

# 3rd Party Libraries
from pyaeso import ets

end_date = datetime.date.today()
start_date = end_date - datetime.timedelta(1)

f = StringIO()
ets.dump_pool_price(f, start_date, end_date)
f.seek(0)
#print f.getvalue()
data = list(ets.parse_pool_price_file(f))
f.close()

print '''Yesterday's market clearing price/demand points.'''
for d in data:
   print d.t.astimezone(ets.ALBERTA_TZ), '$' + str(d.price), str(d.demand) + 'MW'

Known Incompatibilities

  • Python <= 2.3 - Fails because pyaeso uses several standard library modules that were introduced in Python 2.4.
  • Python 3 - pyaeso uses the pytz package which has no Python 3 version (2009-11-14). The pyaeso library should be quickly available for Python 3 once pytz is updated.
