**Model code:**

``` python
stateON = AssetState('ON')
addGradients(asset, stateON, isInput=True)
# Computing overall cost to set on incoming flows (consumption cost + network exit fee)
overallConsumptionCost  = getAssetData(asset, CONSUMPTION_COST, dataName=LABELS[CONSUMPTION_COST], mustExist=False)
exitFee = getAssetData(asset, "EXIT_FEE", mustExist=False)
if exitFee is not None:
	overallConsumptionCost += exitFee
   
# Computing overall cost to set on outcoming flows (production cost + network entry fee)
overallProductionCost  = getAssetData(asset, PRODUCTION_COST, dataName=LABELS[PRODUCTION_COST], mustExist=False)
entryFee = getAssetData(asset, "ENTRY_FEE", mustExist=False)
if entryFee is not None:
	overallProductionCost += entryFee
   
addEnergyTransmission(asset, stateON, consumptionCost = overallConsumptionCost, productionCost = overallProductionCost)
# Add minimum flows constraints
minimumFlow = getAssetData(asset, MIN_FLOW, mustExist=False, resizePercentage=True)
if minimumFlow is not None and minimumFlow > 0:
	addMinimumFlow(asset, stateON)
