We present an electricity demand forecasting algorithm
based on Gaussian processes. By introducing a taskspecific,
custom covariance function kpower, which incorporates
all available seasonal information as well
as weather data, we are able to make accurate predictions
of power consumption and renewable energy production.
The hyper-parameters of the Gaussian process
are optimized automatically using marginal likelihood
maximization. There are no parameters to be specified
by the user. We evaluate the prediction performance on
simulated data and get superior results compared to a
simple baseline method.
