PZ 1 and PZ2 producer mines PZ 3 producer mine Pricing Zone 3 Pricing Zone 1 Port The Network Note: This is a hypothetical example and is not to scale. Pricing Zone 2 13
Pricing Zone 1 : Economic Cost maximum allowable revenue Maximum allowable revenue = Economic Cost FCC plus NCC (‘common costs’)VCC (Direct Costs) Pricing Zone 3: Economic Cost FCC plus NCC (‘common costs’)VCC (Direct Costs) Note: This is a hypothetical example and is not to scale. 14
PZ 3 producer LOSS (capitalised for recovery from PZ 3 producers in future periods) Revenue is received, based on use of the network… PZ 3 producer PZ 1 and 2 producers Pricing Zone 1 : Economic Cost FCC* plus NCC* (‘common costs’)VCC* (Direct Costs) Pricing Zone 3: Economic Cost Note: This is a hypothetical example and is not to scale. Actual use charge: based on variable maintenance Up-front charge: based on a share of common costs (reflecting contracted consumption of capacity) PZ 3 producer FCC plus NCC (‘common costs’) Actual use charge Up-front charge VCC (Direct Costs) * VCC is variable component of costs, FCC is fixed component of costs and NCC is new capital component of costs 15
