OpenNEM Energy Market Data Access

The OpenNEM project aims to make the wealth of public National Electricity Market (NEM) data more accessible to a wider audience.

This client library for Python enables accessing the Opennem API and data sets.

Project homepage at https://opennem.org.au

Developer documentation at https://developers.opennem.org.au/

Currently supporting the following energy networks:

• Australia NEM: https://www.nemweb.com.au/
• Australia WEM (West Australia): http://data.wa.aemo.com.au/
• APVI rooftop solar data for Australia

1. Requirements

• Python 3.8+ (see .python-version with pyenv)
• Docker and docker-compose if you want to run the local dev stack

2. Quickstart

$ pip install opennem

>>> import opennem

3. Development

3.1 Auto setup and install

For contributions and development of this repository you need to install all the requirements. There are some helper scripts in the scripts/ folder.

$ ./scripts/init.sh

By default the venv is installed in the user local cache folder and not in the project path. To link the venv so that it can be found automatically by the shell or editors run the helper script

$ ./scripts/link_venv.sh
Created .venv

3.2 Manual Setup

3.2.1 Prerequisites

For MacOS and Linux require pyenv and poetry

• pyenv homepage - simple install with brew install pyenv
• poetry install (don't install poetry with brew - see this issue)

3.2.2 Initialize python

We use pyenv for python versioning as it allows a system to run multiple version of python. The version for this project is specified in the .python-version file in the root of the repository.

To install the locally required python version

$ pyenv install `cat .python-version`

To initialize and use the local python version

$ pyenv version local
3.9.6 (set by /Users/user/Projects/Opennem/opennempy/.python-version)

To test the install is correct

❯ python -V
Python 3.9.6
❯ which python
/Users/n/.pyenv/shims/python

3.2.3 Install with poetry

To manually setup the local development environment, simply create the virtual environment, link it and setup the PYTHONPATH

$ poetry install
$ ln -s `poetry env info -p` .venv
$ source .venv/bin/activate
$ pwd > .venv/lib/python3.9/site-packages/local.pth

Alternatively to actiavate the virtual environment poetry has a shell command:

$ poetry shell
Spawning shell within /Users/n/Library/Caches/pypoetry/virtualenvs/opennem-pFt2SfpM-py3.9
$ which python
/Users/n/Library/Caches/pypoetry/virtualenvs/opennem-pFt2SfpM-py3.9/bin/python

3.2.4 Install with venv

Alternatively if you do not wish to use poetry you can setup a simple venv in the local folder and activate it.

$ python -m venv .venv
$ source .venv/bin/activate
$ pip install -r requirements.txt

3.3 Test Install

You should be able to run a Python REPL (like iPython) and import the opennem module

$ ipython
