With more than 30,000 km of ACCC conductor in service in 35 countries, the ACCC conductor's improved efficiency is saving over 12.2 million metric tons of CO2 annually. This is the equivalent of removing 2.6 million cars from the road. Visit www.ctcglobal.com for more information

1. How Modern Technology
is Improving the Efficiency,
Capacity and Reliability of the Grid

2. 1900 2000
Generation, Transmission and Demand-Side Appliances saw improvements,
but the fundamentals remained basically the same.
During the last century not much changed

3. 2010 +++
Why…
Because Efficiency, Capacity and
Reliability Offer Substantial
Economic & Environmental Benefits
Globally, we invested billions of dollars improving the efficiency of generation and
demand-side appliances. Now we are investing billions more gathering data about
generation capacity & consumer habits. Some call this “Smart Grid.” What about
the grid itself?
Until Now

4. • Inaccurate telemetry data and computer glitches led to excessive conductor sag.
• Conductor sag led to a series of short circuit events that knocked out the entire grid.
• The economic impact was estimated to approach $10 billion dollars.
Recall the major blackout of 2003
Following that major event, the Energy Policy Act of 2005 provided a number of incentives
to leverage new technology that could be used to “improve the efficiency, capacity and
reliability of the grid.” This included modern high-capacity, low-sag conductors.

5. High-Capacity, Low-Sag Conductors offer several advantages
• They allow for load growth;
• They allow for the integration of renewables;
• They offer added capacity for emergency “N-1” conditions;
• They substantially reduce thermal sag to improve grid reliability;
• They offer improved resistance to corrosion and cyclic load fatigue;
• They offer improved toughness and resiliency.

6. High-Capacity, Low-Sag Conductors also offer:
Improved Energy Efficiency
• ACCC reduces line losses by 25 to 40% or more depending upon load level
compared to other conductors of the same diameter and weight.
• Line loss reductions can serve to reduce fuel consumption and associated
emissions and/or improve the economic viability of various renewables.
• Reduced line losses also frees-up generation capacity that is otherwise
wasted.

7. 100 mile 345 kV line – replace ACSR with ACCC
 Increased line capacity by 57% with 700 amp emergency reserve
 Reduced line losses by 30%
 Line loss reduction saves ~ 300,000 MWh / year (=$19M @$0.06 / kWh)
 Emission reductions saves ~ 200,000 Metric Tons CO2 / year
 This equates to removing over 42,000 cars from the road
 Line loss reduction also frees up ~ 50 MW of generation ($50M+)
Project Example:
Notes:
Doubled bundled conductor
No structural modifications
Load factor = 62%
US National Average CO2 = 1.372# / kWh
1 car = 4.75 MT CO2 / year
Cost of wire ~ $12.7M

9. 30,540 km ACCC energized
125,865 km in cumulative service
12,215,924 Metric Tons CO2 saved annually
This is the equivalent of removing 2.6 million cars
50,346,085 Metric Tons CO2 saved cumulatively
(1 passenger car produces ~ 4.75 MT of CO2/year)
Environmental Impact so far:
Note: over 35,000 km of high-capacity, low-sag ACCC
conductor has been selected by over 175 utilities in 35
countries for ~375 projects. ACCC conductor was
commercially deployed in 2005 and is now produced
by over 20 regional manufacturing companies globally.
