The Stream model consists of three Excel spreadsheet models:

1. The energy savings model

This deals with energy savings by means of better efficiency both in the respective energy products and services.

Different estimates regarding saving-potentials can be used here to see what consequences they are likely to have in the long term.

2. The duration curve model

This takes into account the demand for heat and power and calculates the potential for energy infrastructural changes, factoring in the flexible demand, and generation from fluctuating electricity technologies (wind, solar PV etc.)

Here different approaches to the degree of flexibility of the energy system can be experimented with.

3. The energy flow model

Lastly, the input and output from the energy savings and duration curve models are put into this model, thereby creating an overview of the total energy consumption, emissions and costs from a total energy systems perspective.

In this model an overview is created so that it is possible to see whether the premises that have been used as input in the two other models will actually be enough to reach the goals.
