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
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
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.
