Introduction

• CTC Global is an ACCC conductor
  manufacturing company that was founded to
  develop, certify and deploy advanced technologies
  to improve the efficiency, capacity, reliability
  and resiliency of the electric power grid.
• Our primary product is high-capacity, low-sag
  CTC Global ACCC Conductor solutions.

• Most of us associate the word efficiency with
  improvements in generation equipment,
  transformers and demand side appliances.
• While new more efficient components in many cases
  are more expensive than the less efficient units
  they replace, their higher prices have generally
  been easy to justify due to their reduced
  operating and lifecycle costs.

Smart Grid Strategy 

• Smart Grid strategy was developed to help
  decrease peak load demand by shifting certain
  tasks to off peak hours. Recharging electric
  vehicles, being one example.
• Whats surprising is how little any of us
  actually think about the efficiency of the grid
  itself that connects our appliances, homes and
  electric cars to generation. Most of the wire
  used for this currently consists of aluminum
  strands wrapped around a steel core. This wire is
  called ACSR (Aluminum Conductor Steel
  Reinforced) and the technology is more than 100
  years old.

A new conductor design was created

• It was named ACSS (Aluminum Conductor Steel
  Supported). Its very similar to ACSR, but the
  aluminum strands were pre-annealed in the
  factory. This allowed ACSS to operate at higher
  temperatures to accommodate increased loads.
• The problem with ACSS is that at higher operating
  temperatures, line losses climb exponentially.
  The other problem is that as the wire heats up
  due to electrical resistance, its high
  coefficient of thermal expansion causes it to sag
  which can lead to sag-trip outages. The major
  east coast blackout of 2003, for instance, was
  caused by excessive conductor sag.

To Mitigate Conductor Sag

• In the wake of the major east coast blackout a
  number of companies including 3M and Composite
  Technology Corporation (now CTC Global)
  introduced HCLS (High-Capacity, Low-Sag)
  conductors.
• The ACCR core is actually a fiber reinforced
  aluminum, so its electrical resistance (and
  efficiency) is greatly improved over conventional
  steel core that offers very poor conductivity.
  The CTC Global product ACCC (Aluminum Conductor
  Composite Core) uses a non-conductive carbon and
  glass fiber core.
• Because CTC Globals ACCC core is so much lighter
  than steel, the design incorporates an additional
  28 percent more aluminum without a weight or
  diameter penalty. The added aluminum content (and
  improved quality) serves to lower electrical
  resistance and therefore effectively reduces line
  losses by 25 to 40 percent or more compared to
  steel reinforced alternatives.

While many leading executives have stated

• Its cheaper to save a Nega Watt than it is to
  produce a Mega Watt, in the case of delivering
  power, this is also very true. To put this in
  even greater perspective, a CO2 reduction of
  80,000 Metric Tons is the equivalent of removing
  nearly 17,000 cars from the road. 
• If you clip this down into a one-mile section,
  that will equate to a CO2 reduction of 667 Metric
  Tons or a reduction of 140 cars per mile.
  Assuming a reconductoring cost of 300,000 per
  mile, this would equate to a one-time cost of
  450 per Metric Ton using a high-performance
  conductor. Though things are changing quickly,
  the feds currently offer a 7,500 rebate for
  purchasers of electric cars. That equates to a
  government investment of 1,579 to save one
  Metric Ton of CO2 not including the cost of the
  car on top of it.
