Annual Quantity (AQ): Estimated annual gas consumption of a meter, as determined by Xoserve from previous read history.
Automated Meter Reading (AMR): AMR is a unit which can be attached to a customer’s meter which will then transmit the reading from the meter at 06.00am each day. Along with the reading at 06:00am, are the readings taken every half an hour for the previous 24 hours.
Billing Period: Corona Energy invoices will always be issued for an entire month, starting at 06:00am on the 1st and finishing at 05:59am on the 1st of the following month.
British Thermal Unit (BTU): The amount of heat required to increase the temperature of one pound of water one-degree Fahrenheit. A BTU is used as a common measure of heating value for different fuels.
Calorific Value: Daily Xoserve provided figure denoting the energy value of gas in a given local distribution zone. The CV is used in calculating kWh from cubic feet of gas.
Capacity Charge (Transportation): The cost for establishing and maintaining the network of pipes to supply gas to each premises.
Commodity Charge (Transportation): The cost payable for moving gas through the pipe network to each premises.
Correction Factor: The CF is another Xoserve provided figure. Because gas is pumped at slightly differing pressures due to space, temperature and altitude the cubic feet of gas consumed is multiplied by the CF to level out these differences. The most common CF is 1.02264.
Corrector Meter: On large meters a second meter measuring gas at a slightly different rate is attached. This provides a more accurate alternative to the correction factor.
Cubic Foot: The amount of gas needed to fill a volume of one cubic foot at 14.73 pounds per square inch absolute pressure and 60 degrees Fahrenheit. One cubic foot of natural gas contains on average, 1,027 BTUs.
Daily Metered Consumer (DMC): A supply point with a high Gas consumption (typically more than 58,600,000 kWh), for which we measure the Gas consumption on a daily basis.
