Gas Energy Factors

What is the Cost Adjustment Factor (PNGCAF)? (Also referred to as the Fuel Cost Adjustment)

Mesa employs a purchased natural gas cost adjustment factor (PNGCAF) that permits Mesa to recover the costs associated with the planning, acquisition and administration of required natural gas supplies and transportation services from its customers on a timely basis.  Such costs are recovered in the "Gas Cost Adjustment" (GAF).  The PNGCAF is determined on a forward fiscal year basis for each month therein and is reviewed each month and adjusted as necessary to reflect known and measurable changes to costs and customer consumption.  This allows Mesa to better match its costs with its revenues and also provides its customers with natural gas energy price signals to allow them to better manage their consumption patterns and associated costs.

What is the Heating Value Factor?

The Heating Value (HV) factor, expressed in Therms per Hundred Cubic Feet (Th/Ccf), allows for the conversion from the metered natural gas flow volume measured in Ccf to energy denoted in Therms (Th).  For example, if the metered natural gas flow volume was 100 Ccf, assuming a HV factor of 1.020, the gas energy billed will be 102 Therms (100 x 1.02).

Heat Value Factors and Energy Factors

Natural Gas Conversion Factors:

1 BTU = amount of energy required to raise the temperature of one pound of water, one degree Fahrenheit.
 1 CF (Cubic Feet) = Approx. 1,000 BTU's
 1 CCF    = 100  CF = 1 Therm
 1 Therm = 100,000 BTU's = 100 CF =  0.1 MCF
 10 Therms  = 1 MCF
 1 MCF   = 1,000 CF  = 10 CCF = 10 Therms
 1 Quad  = 10 9 MCF  = 1010  Therms =  1015 BTU's
 8.338 pounds = 1  gallon of water 

 

Electric Energy Factors

What is the Electric Energy Cost Adjustment Factor (EECAF)?

Mesa employs a purchased electric energy cost adjustment factor (EECAF) that permits Mesa to recover the costs associated with the planning, acquisition and administration of required electric energy supplies and transportation services from its customers on a timely basis.  Such costs are recovered in the Budget Electric Energy Cost (BEEC).  The EECAF is determined on a forward fiscal year basis for each month therein and is reviewed each month and adjusted as necessary to reflect known and measurable changes to costs and customer consumption.  This allows Mesa to better match its costs with its revenues and also provides its customers with natural gas energy price signals to allow them to better manage their consumption patterns and associated costs.

Electric Conversion Factors:

Kilowatt (kW) = 1,000  (One Thousand)  Watts 
Kilowatthour (kWh) =1,000 (One Thousand) Watts for 1 hour
Megawatt (MW) = 1,000,000  (One Million)  Watts 
Megawatthour (MWh) = 1,000,000  (One Million)  Watts for 1 hour
1 Horsepower = 746 Watts
1 kWh = 3,413 BTU's

 

Tariff Adjustment Sheet

The Tariff Adjustment Sheet fully discloses the rates used to recover energy resource costs by the district cooling, electric, and natural gas utilities.  The district cooling fuel factor (DCFF) recovers the cost of purchasing electric power.  DCFF is added to the rate per ton hour ($/Ton Hour).  The electric energy cost adjustment factor (EECAF) recovers fixed and variable electric power costs of planning, acquiring, and administering power supplies and associated transmission services not collected by the electric utility's generation energy charge.  EECAF is a per kilowatt-hour charge ($/kWh) that is added to a customer's electric bill referred to as Electric Fuel Cost Adjustment.  The purchased natural gas cost adjustment factor (PNGCAF) is a per therm charge that is added to the customers gas bill, referred to as Gas Cost Adjustment, which allows the City to recover fixed and variable costs of planning, acquiring, and administering natural gas supplies and associated transportation services.
