# Line Extension Cost

### Single Phase

For up to a ¼ mile of line there is NO line extension cost.

½ mile of line will cost:

2640 – 1320 = 1,320 x $6.50 = $8,580.00 x .9 = $7,722.00/60 = $129.00 for 60 months

$5,940.00 x .8 = $6,864.00 for lump sum

¾ mile of line will cost:

3,960 – 1320 = 2,640 x 6.50 = $17,160.00 x .9 = $15,444.00/60 = $258.00 for 60 months

$17,160.00 x .8 = $13,728.00 for lump sum

1 mile of line will cost:

5280 – 1320 = 3,960 x 6.50 = $25,740.00 x .9 = $23,166.00/60 = $386.00 for 60 months

$25,740.00 x .8 = $20,592.00 for lump sum

Please note:

For a single phase overhead primary construction, the cost is $6.50 per ft.

For a single phase primary underground construction, the cost is $10.00 per ft.

### Three Phase

¼ mile of line will cost:

1320 x 9.50 = $12,540.00 x .9 = $11,286.00/60 = $188.00 for 60 months

$12,540.00 x .8 = $10,032.00 for lump sum

½ mile of line will cost:

2640 x 9.50 = $25,080.00 x .9 = $22,572.00/60 = $376.00 for 60 months

$25,080.00 x .8 = $20,064.00 for lump sum

¾ mile of line will cost:

3960 x 9.50 = $37,620.00 x .9 = $33,858.00/60 = $564.00 for 60 months

$37,620.00 x .8 = $30,096.00 for lump sum

1 mile of line will cost:

5280 x 9.50 = $50,160.00 x .9 = $45,144.00/60 = $752.00 for 60 months

$50,160.00 x .9 = $45,144.00 lump sum

Please note:

For a three phase overhead primary construction, the cost is $9.50 per ft.

For a three phase primary underground, the cost is $15.00 per ft.
