REBUILD
FPL rebuilt a 17-mile 230kV line, doubling capacity from 1,495 to 3,198 amps and using smaller single-piece structures instead of the two-piece structures required for ACSS.
This resulted in substantial CapEx savings, with total structure and conductor costs reduced by over $2.5 million.

GREENFIELD
Basin Electric constructed a new 27-mile 230kV line in North Dakota, reducing structure height and quantity by 15%, from 183 to 155.
These reductions offset the price difference between traditional ACSR and TS Conductor while providing increased capacity for future RTO requirements.

RECONDUCTORING
MDU completed a 11-mile reconductoring project on a 230kV line, avoiding all structure modifications required by ACSS.
The project saved 40% on estimated construction costs. Reconductoring was completed a year ahead of schedule, resulting in $1.8 million in savings.
8.5 MI
SRP upgraded 8.5 miles of double circuit 230kV line in Phoenix, significantly increasing capacity without replacing existing towers.
The project was completed ahead of schedule, with final costs coming in under the $11.5 million budget at $10.1 million.
