What is the Raw Material Cost Adjustment System?
- The prices of LNG (liquefied natural gas) and LPG (liquefied petroleum gas), the raw materials for city gas, fluctuate due to factors such as crude oil prices and exchange rates.
- The raw material cost adjustment system was introduced to quickly reflect these fluctuations in raw material prices in monthly gas bills.
Calculation of adjustment unit fee and Raw material adjustment unit price
Adjustment unit fee
- Standard average raw material price
The price will be 85,350 yen per ton.
- Average raw material price
The average raw material price is calculated using the following formula based on the quantity and value of imported goods in trade statistics.
Average raw material price = A x 0.9423 + B x 0.0620
A = Average LNG price per ton for each average raw material price calculation period
B = Average LPG price per ton for each average raw material price calculation period
