Introduction
CTC Global commends the authors of “Large-Scale Transmission Deployment Saves Consumers Money” – Zach Zimmerman, Michael Goggin, Rob Gramlich, and Gretchen Kershaw – for publishing a compelling and evidence-driven case for high-capacity transmission infrastructure. Sponsored by Americans for a Clean Energy Grid (ACEG), this June 2025 report confirms what grid planners and forward-thinking utilities have long understood: modernizing our transmission grid is a cost-effective, reliability-enhancing, and climate-aligned investment.
Key Findings from the Grid Strategies Report
The report underscores the magnitude of benefits from high-capacity, well-planned transmission:
- $6.3 to $10.4 billion in annual net savings for residential consumers – rising to $8.7 to $14.4 billion when post-construction benefits are considered.
- Across all sectors (residential, commercial, and industrial), total annual consumer savings could reach $38.3 to $88.0 billion.
- Every U.S. household could save over $100/year on electric bills if high-voltage, coordinated regional planning were adopted nationally.
- Benefit-to-cost ratios between 3.8 and 4.7 – meaning for every $1 invested, consumers receive up to $4.70 in benefits.
- High-capacity (765 kV) transmission can deliver power at just 25% of the cost per megawatt-mile compared to 230 kV lines.
- Delaying or underbuilding transmission leads to higher generation costs, greater emissions, and greater consumer vulnerability to outages and price shocks.
The report’s methodology is robust, analyzing benefit-cost ratios from 16 major regional and interregional studies across PJM, MISO, SPP, ERCOT, ISO-NE, and NYISO, as well as input from DOE’s National Transmission Needs and Planning Studies.
CTC Global’s ACCC® Conductor: A Ready-Made Solution for Today’s Grid Imperatives
The economic, operational, and environmental insights in this report map directly onto the proven capabilities of CTC Global’s ACCC® Conductor. As utilities strive to deliver more power through existing corridors or face high land and permitting costs for new routes, the ACCC® Conductor offers unmatched performance:
- Higher Ampacity and Greater Transfer Capacity
The ACCC® Conductor can double the capacity of existing transmission lines without requiring new towers or rights-of-way. This is essential when trying to relieve congestion or deliver bulk power over long distances – a key theme in the report.
- Superior Efficiency and Reduced Line Losses
The report emphasizes that transmission efficiency reduces energy costs during peak demand. The ACCC® Conductor has line losses 25% to 40% lower than ACSR and ACSS, translating to:
- Lower fuel burn and emissions at the generation side,
- Greater delivered power during congestion events,
- Higher returns on infrastructure investment.
- Proven Economics in the Field
Just as the report documents regional benefit-cost ratios as high as 4.7:1, multiple case studies show ACCC® Conductor deployments producing a positive ROI within years. For instance, a project in Texas demonstrated recovery of installation costs in under 3 years due to reduced system losses and deferred capacity upgrades.
- Enhanced Reliability and Climate Resilience
CTC Global’s composite core resists thermal sag even at operating temperatures of 180°C, maintaining clearance and safety even under extreme load or weather conditions – vital during grid stress events such as polar vortexes or heat domes.
- Rapid Deployment with Minimal Permitting
In a regulatory environment where building new transmission lines can take 7–10 years, reconductoring with ACCC® Conductor allows utilities to deploy higher-capacity lines in as little as 12 to 24 months, sidestepping major permitting delays.
Aligning With the Report’s Broader Vision
The Grid Strategies report makes a strong case that high-voltage transmission is a national economic and security imperative. It calls for:
- Coordinated regional and interregional planning,
- Investments that accommodate future demand from AI and manufacturing,
- Modern infrastructure that reduces generation overbuild and congestion,
- A departure from short-term, piecemeal fixes.
CTC Global is proud to provide a field-proven solution that advances every one of these objectives. The ACCC® Conductor has already helped more than 300 utilities in over 65 countries and 30 U.S. states expand capacity, improve reliability, and reduce emissions – often under tight timelines and constrained budgets.
A Call to Action
Utilities, regulators, and policymakers now have the economic analysis they need to act. As the Grid Strategies report shows, the cost of inaction is greater than the investment in transmission itself. With electricity demand surging and reliability concerns mounting, now is the time for strategic, large-scale upgrades.
CTC Global stands ready to support this effort with engineering expertise, a reliable global supply chain, and the industry’s most trusted high-performance conductor solution.
