TS Conductor's reconductoring bet: carbon-core cables carry 3x power, $134M plant
TS Conductor bets carbon-core cables will replace steel wires on existing towers; $60M Series B in 2024, $134M plant opened May 2026.
TS Conductor
What the business is
TS Conductor makes AECC (aluminum-encapsulated carbon-core) transmission cables that carry two to three times the power of standard steel-core ACSR wires on the same towers, sold to utilities for reconductoring projects.
Starting capital：$60M Series B announced 2024-07-30, led by Wellington Management with Breakthrough Energy Ventures, National Grid Partners, Edison International, NextEra Energy Resources and Quanta Services (Canary Media).
How it started
Jason Huang founded TS Conductor in Huntington Beach, California to commercialize a pre-tensioned carbon-composite core that replaces the steel in ACSR cables. Its first US deployment was with Montana-Dakota Utilities in 2021; the Southern California factory opened in 2023 and quickly ran near capacity.
What happened
Policy turned its way in 2024–2025: FERC Order 881's ambient-adjusted rating mandate (compliance July 2025), FERC interconnection and transmission-planning reforms, DOE grant programs and state laws pushed advanced conductors onto utility plans. GridLab and UC Berkeley studies (April 2024) found advanced conductors could quadruple the pace of capacity expansion by 2035 at lower cost. On 2024-07-30 TS Conductor raised a $60M Series B to build a factory with roughly 10x the 5,000-miles-per-year capacity of its California plant.
How it ended up
The $134M Hardeeville, South Carolina plant (three phases, 462 jobs, $28M DOE support) opened 2026-05-13, lifting phase-one production capacity 10x. SRP's 8.5-mile Phoenix reconductoring with AECC Cloudveil M3 delivered an 80% capacity jump, ahead of schedule and 12% under budget.
Background
TS Conductor, founded by Jason Huang in Huntington Beach, California, makes AECC — an aluminum-encapsulated carbon-core cable that carries two to three times the power of the steel-core ACSR wires standard on the US grid, on the same towers and with standard fittings. Its bet was that utilities would re-conductor existing lines rather than spend a decade permitting new corridors.
Regulatory tailwinds arrived in 2024–2025: FERC Order 881's ambient-adjusted rating mandate (compliance by July 2025), FERC interconnection and transmission-planning reforms, DOE grant programs and state laws all forced advanced conductors onto utility plans. GridLab and UC Berkeley studies in April 2024 found the technology could quadruple the pace of capacity expansion by 2035 at lower cost than new lines.
In July 2024 TS Conductor raised a $60M Series B led by Wellington Management with utility and infrastructure investors, and in May 2026 it opened a $134M South Carolina plant with $28M in DOE support, lifting production capacity 10x in phase one. A flagship project with SRP in Phoenix delivered an 80% capacity jump on an 8.5-mile line, ahead of schedule and 12% under budget — the proof utilities needed to treat reconductoring as a default option.
What has to be true
- TS Conductor bet on reconductoring because new transmission corridors take up to a decade or more and are often killed by permitting and legal challenges.
- FERC Order 881 and later planning and interconnection reforms forced utilities to consider advanced conductors, lowering the buyer's adoption risk.
- The $60M Series B from utility and infrastructure investors, then the $134M factory, show capital followed the policy window rather than waiting for organic demand.
- The SRP Phoenix result — 80% more capacity at 12% under budget, with 1970s towers preserved — turned advanced conductors from a niche experiment into a mainstream option.
What can be applied
A mandate that only forces utilities to consider a better technology still opens a market: it lowers buyer risk, letting a premium-priced product win on total-project economics.
Aftermath
As of May 2026 TS Conductor is scaling: the Hardeeville, South Carolina plant opened 2026-05-13 with phase-one capacity 10x the Huntington Beach facility (up to 20x at full buildout), roughly 462 jobs planned, $28M in DOE Manufacturing Deployment Office support, and a $1.9B DOE SPARK reconductoring initiative announced two months earlier. Deployments include Montana-Dakota Utilities (its first, 2021), Tennessee Valley Authority, Arizona Public Service, and SRP's Phoenix line.
