Question 1

How do I set up the EIA API key for this project?

Accepted Answer

You'll need to obtain an API key from the EIA website and configure it in the R scripts that use jq for data pulling. However, detailed setup steps might be sparse due to the WIP documentation, so refer to the EIA API documentation for guidance.

Question 2

What's the forecast accuracy of the GLM model compared to ARIMA?

Accepted Answer

The GLM model is a generalized linear model from h2o, which is simpler and might be less accurate for complex time series than ARIMA or Prophet models. The project doesn't provide benchmark comparisons, so accuracy may vary and require validation for specific use cases.

Question 3

Can I use USelectricity for solar energy forecasting?

Accepted Answer

Currently, it focuses on total electricity demand and net generation. To adapt it for solar energy, you'd need to change the data source to include renewable metrics and potentially adjust the GLM model, which might not handle intermittent patterns well.

Question 4

How does this compare to Python projects using fbprophet for energy forecasting?

Accepted Answer

USelectricity is built in R with h2o's GLM, while Python projects often use libraries like Prophet or scikit-learn. The key difference is the technology stack; USelectricity is better for learning R-based deployment, but Python offers more model flexibility and a larger community for energy forecasting.

Question 5

How to change the forecast horizon from 72 hours to a week?

Accepted Answer

You would need to modify the R code that defines the forecast period in the h2o model training script and adjust the GitHub Actions schedule. This might require retraining the model with different parameters and testing for performance trade-offs.

Question 6

What are the costs of running the GitHub Actions automation?

Accepted Answer

GitHub Actions offers free minutes for public repositories, but for hourly data refreshes and 72-hour forecast cycles, you might hit limits in private repos or with high usage. Monitor your repository's action logs to avoid potential costs or throttling.
