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

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

Page 3: CTC Global ACCC Conductor efficiency presentation 2016

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

Page 4: CTC Global ACCC Conductor efficiency presentation 2016

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

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

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

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

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)

Page 9: CTC Global ACCC Conductor efficiency presentation 2016

• 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

Page 10: CTC Global ACCC Conductor efficiency presentation 2016

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.

The time has come to leverage high performance conductor technology to improve our Nation’s electric power grid• Reduce line losses to reduce fuel consumption and associated emissions• Double the capacity of existing corridors – with minimal environmental impact• Open up pathways for increased renewable access• Cost effective solution with many added benefits

An Efficiency Standard Needs to Guide, Inspire & Reward Transmission Developers to Use High Efficiency Conductors – if not a huge opportunity will be missed and consumers will pay the price. Thank You
