# 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

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
