The R package MEFM includes a set of tools for implementing the Monash Electricity Forecasting Model based on the paper by Hyndman and Fan (2010).
The package requires the following data as input: half-hourly/hourly electricity demands; half-hourly/hourly temperatures at one or two locations; seasonal demographical and economical data; public holiday data. The formats of the required data are described in the help files.
Some documentation of the underlying model is provided at http://robjhyndman.com/working-papers/mefm/.
The package itself is hosted on github and can be installed as follows:
install.packages("devtools") library(devtools) install_github("robjhyndman/MEFM-package")
