# WELCOME!

Welcome to the January 20 1 1 issue of the Clean Cities Alternative Fuel Price Report, a quarterly report designed to keep you up to date on the prices of alternative fuels and conventional fuels in the U.S

. This issue summarizes prices that were collected between January 2 4

, 201 1 and February 7 , 201 1 from Clean Cities Coordinators, fuel providers, and other Clean Cities stakeholders.



# METHODOLOGY

In order to collect price information for both

alternative fuels and conventional fuels from areas across the country, Clean Cities Coor dinators, fue l providers, and other key stakeholders were contacted to request that they provide prices for fuels in their area on a voluntary basis

. Prices were collected on all major alternative fuels currently in widespread use (natural gas, propane, bi odiesel, and ethanol), as well as prices for conventional fuels at stations that also sell alternative fuels (or stations nearby)

. Prices were collected from public and private refueling stations throughout the country, and were collected between January 2 4

, 201 1 and February 7 , 201 1 . Prices were then averaged in order to determine regional price trends by fuel and variability in fuel price within regions (and among regions)

. Prices in this report are grouped by U.S. areas as defined by the

Petroleum Admini stration for Defense Districts (PADD): the districts are illustrated in the map to the right.

The prices collected for this report represent retail, at

- the

- pump sales prices for each fuel, including f ederal and s tate motor fuel taxes

. In some cases, price s were collected from government or utility refueling facilities and these taxes were not included in the reported price

. In these instances, although these users are not required to pay these taxes, the taxes were added to the reported price to p rovide

a more representative basis for comparison of fuel prices for the purpose of this report

. In some cases, states may charge a flat annual fee for motor fuel taxes (especially for gaseous fuels like compressed natural gas ) : these fees are not considered in the prices reported in these pages.

# SUMMARY OF CURRENT REPORT INFORMATION

Overall nationwide average prices for

conventional and alternative fuels are shown

in Table 1. 1 

### As this table illustrates, alternative fuel prices relative to conventional fuels vary, with some (biodiesel ) higher and some ( CNG, E85

, and propane ) lower

. CNG

is about $1. 15 less than gasoline on an

energy

- equivalent basis, while E85 is about

3 3 cents less per gallon than gasoline

. Propane is about 3 cents per gallon less than gasoline. B20 prices are higher than regular diesel by about 5 cents

. B99/B100 blends

have a cost of about 60 cents per gallon more than regular diesel

. 2



### Relative to the last rep ort from October 20 1 0, the average prices for all of the fuels included in this price report have increased by as

much as 38 cents. It should be noted that the price increases ( or decreases ) could be attributed both to an actual increase in price and to

a slightly differing sample of prices (both location and quantity).

Prices in this report were collected and are reported in the units in which they are typically sold (dollars per gallon or dollars per gasoline gallon equivalent)

. Because of differing energy contents per gallon for these fuels, the price paid per unit of energy content can differ somewhat from the price paid per gallon

. Table 2 illustrates the fuel prices from Table 1 for the current reporting period normalized to a price per gasoline gallon equivalent (GGE)

, per diesel ga llon equivalent (DGE)

, or per million Btu of energy

. This calculation involves the use

of nominal lower heating values in Btu per gallon of fuel which can be found in the Transportation Energy Data Book

. 3


### Note that prices for the alternative fuels in terms of cost per gallon equivalent are generally higher than their cost per gallon because of their lower energy content per gallon

. 4 

### It has been seen, however, that consumer interest in alternative fuels increases as the price differential per gallon increase s, even if

that differential does not directly translate to savings on an

energy

- equivalent basis.

1 A very small sample ( 4 points) of hydrogen information was received: average price for hydrogen was $ 4.88 per g asoline g allon equivalent in this report.

2 ASTM specifications now include blends of up to 5% biodiesel as regular diesel fuel, therefore the separate listing for B2/B5 has been discontinued from this and subsequent reports.

3 A listing of the conversion factors used appears as an appendix at the end of this report.

4 For ethanol flexible

- fuel vehicles, the actual difference in energy cost per mile is somewhat less than would be calculated simply on the differen ce in energy content of the fuels, as some

so urces have noted many FFVs can achieve better energy efficiency (miles per unit of energy) on E85 than on gasoline. This effe ct is not currently included in these calculations as the magnitude of the effect varies by vehicle.

# GASOLINE AND DIESEL PRICES

Average prices for gasoline and diesel as collected by Clean

Cities coordinators and other stakeholders (supplemented where necessary with other

reference sources for conventional fuels) are illustrated in Table 3. These prices were collected from refueling stations selling both conventional fuels and alternative fuels, a nd from conventional fuel refueling

stations near alternative fuel

stations

. There were 438 price points collected for gasoline and

389 for diesel, with average prices for gasoline ranging from

a low of $ 2. 89 per gallon i n the Rocky Mountain region to a high of $ 3.28 per gallon on the West Coast. Diesel prices ranged from $ 3.32 i n the Lower Atlantic region and $ 3.61 i n the New England region

. Because prices for conventional fuels were collected from stations and regions providing alternative fuel price in formation, data collection was not uniform across the regions of the country

. The information is, however, representative of refueling stations selling both alternative fuels and conventional fuels.

Table 4 illustrates average prices as provided by the DOE Energy Information Administration (EIA) on the petroleum information section of

its website

. 5 

### These prices are averages of prices from a selection of 800 retail fuel stations across the country

. Note that the average nationwide price from EIA generally matches relatively closely with the averages from

the station information collected from Clean Ci ties stakeholders

. C omparisons in this document between conventional fuel prices and alternative fuel prices will be made using prices collected from Clean Cities representatives wherever possible, as these prices are most representative of

stations sellin g both conventional and alternative fuels.

# COMPRESSED NATURAL GAS (RELATIVE TO GASOLINE)

Average prices for compressed natural gas (CNG) for vehicle use are illustrated in Table 5, grouped by region. Information on prices for regular gasoline as provided by Clean Cities representatives is

also shown

. These prices were collected from across the country from Clean Cities Coordinators, fuel providers, and other stakeholders on a voluntary basis.

Over 295 CNG prices were collected in this report

. 6



### As Table 5 illustrates by region,

CNG has a lower price than gasoline for all regions of the country for which prices were obtained, with the largest difference ($ 1. 52 per GGE ) being in the Rocky Mountain region. On average, CNG costs about $ 1. 15 less than gasoline on a per gasoline gallon equivalent basis

. Variability of CNG prices was higher (based on a standard deviation analysis) than variability of gasoline prices.

The map to the right illustrates some cost differentials by state for natural gas rela tive to gasoline, based on differentials between natural gas prices and gasoline prices for each state (versus the regional averages illustrated in Table 5). In this map, negative numbers represent costs for natural gas lower than costs for gasoline. State s not highlighted with a color did not have any natural gas data points in the current report. As the map illustrates, CNG prices were favorable relative to gasoline in most states across the country.

6 Prices for CNG were provided by the individual stakeholders in gasoline gallon equivalents from the “price at the pump.” It should be noted that the internal conversion factor between the physical quantities of gas delivered and g asoline g allon e quivalent was not collected from each of the refueling stations. Regional differences in gas heat content relative to the internal pump

conv ersion factor may change the price per g asoline g allon e quivalent : these differences were not determined for this report, however.

# COMPRESSED NATURAL GAS (RELATIVE TO DIESEL) 7



### Average prices for compressed natural gas for vehicle use are illustrated in Table 6, grouped by region. Information on prices for

conventional diesel fuel as provided by representatives from

Clean Cities and supplemental

sources is also shown

. These price s were collected from across the country from Clean Cities Coordinators, fuel providers, and other stakeholders on a voluntary

basis

. Note that the CNG prices in Table 6 are the same group of prices as for Table 5, but converted to a cost per diesel gallon equivalent basis, in order to compare directly with diesel prices

.

As Table 6 illustrates by region, CNG has a lower price than diesel fo r all regions of the country, with the largest difference ($ 1

. 86 per DGE ) being in the Rocky Mountain region. On average, CNG costs about $ 1. 30 less than diesel on a per diesel gallon equivalent

basis

. Based on standard deviation calculations, CNG appears to have had more variability in price during this time period relative to

diesel fuel.

The map to the right ill ustrates some cost differentials by state for natural gas relative to diesel, based on differentials between natural gas prices and diesel prices for each state (versus the regional averages illustrated in Table 6). In this map, negative numbers

represent costs for natural gas lower than costs for diesel. States not highlighted with a color did not have any natural gas data points in the current report. As with the comparison to gasoline, natural gas prices relative to diesel were also favorable for many st ates, as the map shows

.

7 A total of 9 LNG price points were collected with an average fuel price of $ 1.75 per gallon.

# ETHANOL (E85)

Average prices for ethanol in an 85% blend with 15% gasoline (E85) are illustrated in Table 7, grouped by region

. Information on prices for regular gasoline as provided by Clean Cities representatives is also shown

. These prices were collected from

across the country from Clean Cities Coordinators, fuel providers, and other stakeholders on a voluntary basis . A total of

420 prices for ethanol were

collected in this data collection

effort.

Note that E85 has a lower average price per gallon than regular gaso line for all regions (see Table 7)

. On average, E85 is about 33 cents lower in price than regular gasoline on a per

- gallon basis, with the largest average differential ( 37 cents) being found in the Central Atlantic region . Based on the calculated standard deviations in this set of E85 price information, it can be seen that price variability for E85 was slightly higher than the price variability for gasoline for the period.

The map to the right illustrates some cost

diffe rentials between E85 and regular gasoline by state, based on differentials between E85 prices and gasoline prices for each state (versus the regional averages illustrated in Table 7). In this map, negative numbers represent costs for E85 lower than for gas oline, and positive numbers represent costs for E85 higher than gasoline. States not highlighted with a color did not have any E85 data points in the current report. In the time period for this report, E85 costs less per gallon than gasoline for most areas for which prices were available: the best pricing

was in the Midwest

# PROPANE

Average prices for propane are illustrated in Table 8, grouped by region

. Information on prices for regular gasoline as provided by representatives from Clean Cities

is also shown

. These prices were collected from across the country from Clean Cities Coordinators, fuel providers, and other stakeholders on a voluntary basis

. Just over 200 propane prices were collected in this reporting period.

As Table 8 illustrates regionally,

propane prices are somewhat higher than gasoline in some regions and lower in others. Overall, propane was about

3 cents per gallon less than gasoline. Based on calculations of standard deviation in prices, it can be seen that propane prices for vehicle use seems to have varied more than gasoline prices during this sampling period. 8



### The map to the right illustrates some cost differentials between propane and regular gasoline on a per

- gallon basis, based on differentials between propane prices and gasoline prices for each state (versus the regional averages ill ustrated in Table 8). In this map, negative numbers represent costs for propane lower than costs for gasoline, and positive numbers represent propane prices higher than gasoline. States not highlighted with a color did not have any propane data points in t he current report. Several regions had states with favorable p ropane prices including the Midwest

, West Coast , and Atlantic regions

.

8 Prices for propane in this report are from both private fleet refueling stations and public refueling sites that can provide propane for vehicles and for other uses. The prices at private stations are generally lower, and may be more representative of the prices the majority of propane vehicle users pay.

# BIODIESEL BLENDS: B20

Average prices for biodiesel in a

20% blend with 80% diesel (B20) are illustrated in Table 9, grouped by region

. Information on prices for regular diesel as provided by Clean Cities representatives is also shown

. These prices were collected from across the country from Clean Cities Coordinators, fuel providers, and other stakeholders on a voluntary basis

. Over 1 25

pr ices were obtained for B20 across the country.

As Table 9 illustrates, biodiesel in a B20 blend has an average price per gallon that is somewhat

more than conventional diesel

fuel in most regions (ranging from 8 cent s less to 16 cents more per gallon). Based on calculations of standard deviation on B20 prices, variability in B20 prices was larger than the variability in price of conventional diesel in most region s

. On average in the U.S.,

biodiesel in a B20 blend costs about 5 cents more per gallon than conventional diesel fuel based on current information

.

The map to the right illustrates some cost differentials between B20 and diesel on a per

gallon basis, based on differentials between biodiesel prices and diesel prices for each state (versus the reg ional averages illustrated in Table 9). In this map, negative numbers represent costs for B20 lower than costs for diesel, and positive numbers represent B20 prices higher than diesel. States not highlighted with a color did not have any B20 data points in the current report. B20 had favorable pricing in a number of states located around the country including in the West

Coast

, Rocky Mountain, Atlantic, and New England regions. Table 9 . Biodiesel (B20) Average Prices by Region from Clean Cities Sources

# BIODIESEL BLENDS: B100/B99

Average prices for high

- level blends of biodiesel (99% or

100% biodiesel with diesel fuel)

are illustrated in Table 1 0

, grouped by region

. Information on prices for regular diesel as provided by Clean Cities representatives is also shown

. These prices were collected from across the country from

Clean Cities Coordinato rs, fuel providers, and other stakeholders on a voluntary

basis . A total of 36 price points

were collected from stations offering B99/B100 for sale across the country.

As Table 1 0 illustrates regionally, the cost of B99/B100 is generally more than the cos t of diesel fuel per gallon in the regions for which data were collected

, up to $1. 80 more than diesel. On average across the nation, B99/B100 is about 60 c ents per gallon higher than regular diesel

. Based on standard deviation calculations on these price points, it appears that prices for B99/B100 varied more widely for most areas in this time period than regular diesel.

The map to the right illustrates some cost differentials between high

- level biodiesel blends and regular diesel on a per

- gallon basis, based on differentials between biodiesel prices and diesel prices for each state (versus the regional averages illustrated in Table 10). In this map, negative numbers represent costs

for these blends that are lower than costs for diesel, and positive numb ers represent prices for these blends that are higher than diesel. States not highlighted with a color did not have any high

- level biodiesel blend data points in the current report. Where data was available for this report, p rices for B100 were

most favora ble in two state s located in the

Gulf Coast and New England regions

# COMPARISON OF PRICES BY REGION FOR PUBLIC AND PRIVATE REFUELING STATIONS

Table 1 2 below summarizes the comparison of prices for all of the fuels included in this report, separated into averages for stations open to the public (public refueling stations) and stations available only to selected fleets or privately

- owned stations (private refueling stations). Private fleet fueling stations can typically negotiate prices lower than retail public stations, if they are willi ng to commit to purchasing large quantities of fuel over an extended period of time. However, private fleet pricing can s ometimes be higher than retail public stations if there are unusual circumstances (remote locations, sites that use very small quantities of fuel, or specia l contracts where unique billing & accounting services or fleet service management fees are rolled i nto the price of the fuel).

As with the other prices in this report, all of these averages are prices with state and federal taxes included, using the pr otocols outlined at the beginning of this document.
