How to Improve the Efficiency, Capacity and Reliability of the Grid with ACCC Conductor  

No matter what role you play in our industry you should read this:

The National Association of Regulatory Utility Commissioners (NARUC) Passes EL-1 Resolution Supporting Advanced Electric Transmission Technology

WHEREAS, A secure, reliable, and resilient power grid integrating generation resources serves as a foundation of a growing economy and is critical to our national security; and
WHEREAS, Regulators, policymakers, and consumers expect generating resources and the grid to perform extremely reliably; and
WHEREAS, A significant portion of the nation's transmission facilities are aged and will require a replacement strategy; and
WHEREAS, Environmental regulations, State renewable energy portfolio standards, State and federal tax policies, other economic factors, and technology developments are causing some electric generation resources to retire, while replacement generation, some of it fueled by intermittent resources, is being sited at other locations on the electric grid; and
WHEREAS, New innovative cost-effective transmission technologies (including, but not limited to, high-capacity/high-efficiency conductors, compact transmission towers, and variable frequency transformers) are commercially available that can increase grid capacity, improve energy transfers, promote greater stability and resiliency, make more efficient use of rights-of-way, reduce transmission line losses, and help to streamline siting and construction activities; and
WHEREAS, New and advanced replacement transmission facilities can be designed to enable a wide variety of new generating resources and can address technical, environmental, and aesthetic issues that might impede or limit the development and operation of these resources; and
WHEREAS, Crowded utility corridors often allow little room for expansion; and
WHEREAS, Some States have established policies that encourage the use of advanced transmission line technologies; now, therefore be it
RESOLVED, That the Board of Directors of the National Association of Regulatory Utility Commissioners (NARUC), convened at its 2016 Winter Committee Meetings in Washington, D.C., encourages utility efforts to: 1) investigate and consider new advanced transmission technologies when replacing aged transmission infrastructure; 2) evaluate new transmission technologies to determine whether they can cost-effectively ensure the continued reliable delivery of electricity while providing greater capacity and enhanced efficiency; 3) consult with the Department of Energy and its National Laboratories to understand advancing transmission technologies; and 4) consider the ability of these technologies to reduce environmental and visual impacts to communities; and be it further
RESOLVED, That NARUC encourages Regional Transmission Organizations/Independent System Operators and other planning authorities to support and consider cost-effective advanced electric transmission infrastructure options that can increase grid capacity, reduce transmission line losses, improve energy transfers, make efficient use of rights-of-way, improve energy efficiency, and help to streamline siting and construction activities in their planning, evaluation and oversight of transmission grid development; and be it further
RESOLVED, That NARUC encourages State public service commissions to include in their oversight of transmission facilities the consideration of cost-effective use of advanced electric transmission technologies in support of the continued provision of affordable, reliable electricity to consumers.

Project Example:

100 mile 345 kV line - Replace ACSR Drake with ACCC Drake

* Increased line capacity by 75% with 625 amp emergency reserve
* Reduced line losses by 30%
* Line loss reductions saves 300,606 MWh / year (assuming a load factor of 62%)
* At a cost of $0.06 / kWh this equals an annual savings of $19.2 million (the cost of the conductor is a fraction of that)
* Assuming the US national average CO2 emission of 1.372 # / kWh this equals a savings of 200,000 metric tons per year
* This is the equivalent of removing 42,000 cars from the road (1 car = 4.75 MT / year)
* Line loss reductions free up 40 MW of generation (saving over $40 - $50 million)
* Eliminated any possible sag violations for improved reliability
* Only a few existing structures were replaced (due to some corrosion)

CTC Global's Field Representatives Meet for Annual Summit
Earlier this month CTC Global's Field Service Team met to discuss field experiences, review installation learnings and capture best practice equipment and methods. As a result of the meeting, new service offerings are being developed, the installation training program has been substantially revised, and updated Installation Guidelines have been published.  You can review the updated guidelines HERE
ACSS vs ACCC Conductor
Why Over 150 Utilities in 40 Countries Have Selected ACCC
  • High Capacity
  • Low Sag
  • High Strength
  • Fatigue Resistant
  • Corrosion Resistant
  • Excellent Self Damping
  • Easy to Install
  • Great for Long Spans
  • Very Tough & Flexible
  • Extensively Lab & Field Tested
  • Excellent for N-1 Conditions
  • Reduced Line Losses & Emissions
  • Free's-up Generation Capacity that is Otherwise Lost


The ACCC Conductor's added aluminum content (without a weight or diameter penalty) allows it to run cooler under any load condition which translates into reduced line losses. Reduced line losses can save fuel, emissions and generation capacity.

The Bottom Line:

In nearly 400 cases the ACCC conductor has provided more than 150 utilities the best economic solution for their specific project needs.

Overview of ACCC Conductor Training, Installation and Operating Experience

With nearly 400 projects completed we have learned a lot. Our job is not only to help you learn the attributes of ACCC, its also to help keep your crews safe during installation. In an effort to share our knowledge base we have created a number of useful documents and training videos.

Free Engineering Manual

To help Transmission and Distribution planners, engineers, policy makers, grid operators, technicians and others take full advantage of the ACCC conductor's attributes, CTC Global has published a 250 page Engineering Manual. It offers a very comprehensive set of design guidelines, case studies, figures and facts about conductors and composite materials, and includes links to additional resources and FAQ's, To download an electronic version please CLICK HERE

Free Engineering Software

CTC Global created CCP to help system planners and engineers compare the ampacity, line losses, thermal and ice load sag, and economic aspects of nearly any conductor type and size, so the numerous advantages of the ACCC conductor can be fully realized. The user simply selects the conductor types and sizes from drop down menus and enters the appropriate values & assumptions highlighted in the yellow boxes. The program is fully functional and uses standard industry formulas (such as IEEE 738-2006). Outputs are readily comparable to Sag10®, PLS CADD™ and other similar programs.
