# Zones indicators¶

Zone views -also called zone indicators- are zone-centered indicators which enable you to analyse or compare one or several zones from a same context. Zone views are often temporal, and more detailed than their KPI equivalent when there is one. NB: Most of them need computation results and will show no data until results are available.

These views can be opened by double-clicking on a zone, then clicking on the view name at the top and finally selecting the wanted view.

## Demand pie chart¶

This view shows, for each energy, a pie chart showing how the demand is divided by demand type at this delivery point. The demand here includes the flexible demand after optimization and non-flexible demand.

## Supply pie chart¶

This view shows, for each energy, a pie chart of the different supply types in the context, with their proportions.

## Cumulative demand¶

This view shows, for each energy, a temporal cumulative view showing how the energy demand is divided by technology at this delivery point. The demands are here shown after optimization (using the consumption of the corresponding assets). This demand can be negative for asset “Voluntary load curtailment”. For asset “Electric Vehicles” with behavior Vehicule to grid, the demand is the difference between consumption and generation of the vehicles.

## Cumulative generation¶

This view shows a temporal cumulative view, for each energy, of the generation at the selected delivery point for each generation technology at every time step as well at the demand level.

## Demand and Net Demand¶

This view shows time series, for each energy, of the demand and net demand, both optimized and unoptimized, for this energy at the selected delivery point. Unoptimized net demand is defined as the difference between unoptimized demand and the must run available capacity. Optimized net demand is defined as the difference between optimized demand and the must run generation.

## Marginal Costs TS¶

This view shows a time series, for each energy, of the marginal cost of generation of this energy at the selected zone.

## Production margin¶

Margin at each time step between available capacity and energy production for a given zone, for a given energy and a given technology:

$\small minMargin_{t, dp, techno, energy} = availability_{t, dp, techno, energy} imes pmax_{t, dp, techno, energy} - production_{t, dp, techno, energy}$

## Stocks¶

This view shows, for each energy, a pie chart showing how the storage capacity is divided by technology.
