Learn how CTC Global ACCC Conductor can be used to improve grid efficiency and reduce carbon emissions by reducing electrical power line losses and help reduce global warming

1. Why We Need to Modernize the Grid
• Following the Major East Coast Blackout of 2003 – that was caused by excessive
transmission line sag – CTC Global Introduced a High Capacity, Low Sag Conductor.
• CTC Global leveraged its composite materials expertise to develop a next
generation overhead conductor that would not exhibit excessive sag even when
carrying twice the current of a conventional steel reinforced conductor.
• The new conductor leveraged carbon fiber composites widely used and proven
in aerospace and other highly demanding applications.
• Today, the technology has been deployed to over 400 projects in 40 countries to
increase line capacity and improve reliability.
• We are here to present an unrecognized benefit that must now be considered
Transmission Line Efficiency

2. Background
100 Year old transmission technology isn’t keeping pace with modern demand
• We are moving to renewables in an effort to meet emission reduction targets
• We are developing advanced demand side technologies to improve efficiency
• But we are missing a key component…
The Solution: Modern Conductors carry twice the power with 30% lower electrical losses
The wires that connect them are highly inefficient

3. The Most Cost Effective Solution…
High Capacity, Low-Sag ACCC conductors have been deployed and proven at more
than 400 project sites in 40 countries since first commercialized over 10 years ago
HIGH PERFORMANCE CONDUCTORS
• Double the capacity of existing corridors – with minimal environmental impact
• Opens up pathways for increased renewable access
• Mitigates excessive line sag and potential FERC clearance violations
• Improves grid reliability and redundancy to help prevent costly blackouts
• Reduces line losses by 25 to 40% or more
• Reduced line losses frees up generation capacity
• Reducing line losses is the LOWEST COST method of reducing CO2 and other GHG emissions

4. The Situation… GRID CONGESTION & LACK OF EFFICIENCY
• Costs consumers billions of dollars every year
• Limits or completely prevents access to clean renewables
• Reduces reliability during unplanned outages
• Represents security risks during cyber or physical attack (inadequate redundancy)
• Causes excessive line sag (and potential NERC violations) which can lead to blackouts
• Causes lines to run inefficiently with very high line losses
The major east coast blackout of 2003 was caused by excessive conductor sag
after telemetry devices, computer glitches and communication systems failed
Excessive line losses waste generation capacity, burn additional fuel,
generate unnecessary emissions and cost consumers money

5. The Situation Continues… We now own climate change
What we should be doing is working to IMPROVE TRANSMISSION LINE EFFICIENCY
• We are building cleaner generation – which is often subsidized
• We are improving the efficiency of demand side appliances – also subsidized frequently
• We are leveraging information and controls to reduce peak demand “Smart Grid”
• We are attempting to build new lines – which continues to face much resistance
We are loosing anywhere between six and twenty percent of all electricity generated

6. The Technology… CARBON FIBER COMPOSITES
Carbon fiber composites have been widely deployed in highly demanding
applications to improve performance, efficiency and longevity for decades
• Developed to improve performance in highly-demanding environments
• Widely proven in aerospace, automotive and infrastructure applications
• Will not rust, rot, corrode, yield or fatigue
• Twice as strong as steel at 1/3 the weight
• Low coefficient of thermal expansion prevents conductor sag
• Lighter weight allows 28% increase in aluminum content – with higher quality
• Added aluminum content and quality IMPROVES TRANSMISSION EFFICIENCY

7. 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 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)
The Proof… 120 Circuit Mile AEP Project Example
 Payback (not including installation cost or generation savings) = 2 years
 30 year advantage (line losses only) = $212 Million
 30 year emission reductions savings = 2.5 Million Metric Tons

8. The National Perspective…
Benefits of Upgrading the Grid with High Performance ACCC Conductor
US Consumption 3,990,000,000 MWh
Transmission Losses (6%) 239,400,000 MWh
30% Reduction using ACCC 71,820,000 MWh
Generation Capacity Savings (100% Capacity Factor) 8,200 MW
Value of Line Loss Reduction (at $50/MWh) $3.6 Billion
Value of Generation Capacity Savings $8.2 Billion
Annual CO2 Reduction (1,372#/MT) 44,688,000 Metric Tons
Equivalent Cars Removed 9,408,000 Cars
Equivalent Homes Powered 7,378,767 Houses
Equivalent Oil Saved 294,883,129 Barrels
According to the Edison Electric Institute the US currently has
~200,000 circuit miles of transmission lines (144 kV and higher)

9. • 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
Over 21,000 miles of high-capacity, low-sag ACCC conductor has been selected by over 175 utilities in 40
countries for >400 projects. ACCC conductor was commercially deployed in 2005 and is now produced by over
20 regional manufacturing companies globally. ACCC has been widely adopted to increase line capacity, but
few utilities, regulators and/or policy makers have considered or valued the highly important efficiency aspect.
The Environmental Impact… SO FAR

10. The Possibilities
According to EEI the US currently has ~200,000 circuit miles of transmission lines
Imagine the impact of upgrading the most highly stressed lines?
If 25% of the most highly stressed lines in the US were upgraded, a
savings of over 24 Million Metric Tons could be realized each year. That
is the equivalent of removing over 5 Million Cars from the road.
This equates to a cost of $592 per Metric Ton or $2,812 per 4.75 Tons (1 Car)
The current Federal consumer incentive for buying an electric car is $7,500
(which will further stress the electric power grid as they are recharged)
Compared to building 1 MW of wind at a cost of $1 Million per MW
At a capacity factor of 35%, 1 MW of wind saves 1,909 Metric Tons per year
(assuming the National average CO2 value of 1,372 # / MWh). This translates into a
cost of $524 per MT. What do incentives add to this cost?
The estimated cost of reconductoring with ACCC = $285,000/mile.
Reconductoring 25% (50,000 miles) = $14.3 Billion.
