A few of CTC’s International Customers:
Why Did These Utilities Choose ACCC?
Because, after discovering its technical merits and evaluating its durability, it provided the most economical solution for their specific projects
The Value of Line Loss Reduction
Reduced line losses saves money… every year
The Value of Generation Capacity Savings
Reduced line losses reduces generation capacity investmentIt is much less expensive to save energy than it is to produce it
The Value of Emission Reduction
Reduced line losses reduces fuel consumption …and associated emissions
Average car in US = 4.7 mt CO2 / scenario 1 = 13,513 cars / scenario 2 = 53,313 cars
345 kV Line – Replace ACSR with ACCC
• Increased line capacity by 75% with 625 amp emergency reserve• Reduced line losses by 30%• Line loss reduction saves 141,580 MWh / year (=$7.1M @ $50/MWh)• Emission reductions saves 83,316 Metric Tons CO2 / year• This equates to removing over 17,500 cars from the road• Line loss reduction also frees up over 17 MW of generation ($17 M+)
Notes: Double bundled Drake conductor. Load factor Assumption = 34% Texas State Average CO2 = 1.297# / kWh. (1 car = 4.75 MT CO2 / year) Cost of wire ~ $15.4M Assuming installation cost of $18.6 M – total project cost $34 Million Equals ~$285,000 per circuit mile (WECC Estimate basis)
120 Circuit Mile AEP Project Example
ACCC has become the first conductor in history to receive certification and validation for improved energy efficiency
• Over 7,000 circuit miles of ACCC in service • Estimated 3.4 Million Metric Tons CO2 saved annually• The equivalent of removing over 700,000 cars• Cumulative CO2 savings of over 12.5 Million Metric Tons
Environmental Impact… so far (December 2015)

Metric Tons of Carbon saved (added)* per year per $1M Capital investment
* Savings vs. equivalent NG fired plant at 1.12 lbs/KWh and 75% Capacity (wind=35%, hydro=50%). Savings for transmission based on replacing “Drake” sized ACSR constrained line with Drake ACCC - resulting from lower line losses and CO2 emissions at NG generation pollution rates Source: US Dept of Energy 2005 and 2007 studies.
Replacement of a constrained transmission line with ACCC™ conductor saves more CO2 emissions per invested dollar than all other “clean” generation options or transmission solutions
ACCC™ is quick to market and requires limited capital commitment vs:
NGCC = $564M / 2yrsNuclear = $2.8B / 6yrsWind = $60M / 3yrsSolar = $315M / 3yrs
(Source: Energy Information Administration, 2007)
It is cheaper to save a “NEGAWATT” than it is to produce a MEGAWATT
