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 $4.50 = $5,940.00 x .9 = $5,346.00/60 = $89.00 for 60 months
$5,940.00 x .8 = $4,752.00 for lump sum
¾ mile of line will cost:
3,960 - 1320 = 2,640 x 4.50 = $11,880.00 x .9 = $10,692.00/60 = $178.00 for 60 months
$11,880.00 x .8 = $9,504.00 for lump sum
1 mile of line will cost:
5280 - 1320 = 3,960 x 4.50 = $17,820.00 x .9 = $16,038.00/60 = $267.00 for 60 months
$17,820.00 x .8 = $14,256.00 for lump sum
Please note:
For a single phase overhead primary construction, the cost is $4.50 per ft.
For a single phase primary underground construction, the cost is $7.00 per ft.
Three Phase
¼ mile of line will cost:
1320 x 7.50 = $9,900.00 x .9 = $8,910.00/60 = $149.00 for 60 months
$9,900.00 x .8 = $7,920.00 for lump sum
½ mile of line will cost:
2640 x 7.50 = $19,800.00 x .9 = $17,820.00/60 = $297.00 for 60 months
$19,800.00 x .8 = $15,840.00 for lump sum
¾ mile of line will cost:
3960 x 7.50 = $29,700.00 x .9 = $26,730.00/60 = $446.00 for 60 months
$29,700.00 x .8 = $23,760.00 for lump sum
1 mile of line will cost:
5280 x 7.50 = $39,600.00 x .9 = $35,640.00/60 = $594.00 for 60 months
$39,600.00 x .9 = $31,680.00 lump sum
Please note:
For a three phase overhead primary construction, the cost is $7.50 per ft.
For a three phase primary underground, the cost is $12.00 per ft.
