As the global power sector confronts rising demand, climate volatility, and the urgency of decarbonization, the World Bank’s Utility Knowledge Exchange Platform (UKEP) has become a vital forum for utilities seeking practical, deployable solutions. This came through clearly during the recent session, “Integrating Climate Adaptation into Power Systems: Advanced Conductors, Smarter Grids,” where two seasoned practitioners – James Berger, presenting American Electric Power’s (AEP) case study, and Arifur Rahman of Power Grid Bangladesh PLC (PGCB) – shared compelling evidence of how Advanced Conductors are transforming transmission performance in very different settings.
From the outset, the discussion underscored a central point: the world no longer has the luxury of slow, capital-intensive grid expansion. Utilities need solutions that can expand capacity, improve climate resilience, and reduce losses without the delays associated with building new corridors. In both the United States and Bangladesh, CTC Global’s ACCC® Advanced Conductors emerged as a decisive enabler of that shift.
Rahman described PGCB’s ongoing national upgrade program with a matter-of-fact clarity. Bangladesh’s grid must carry more power every year, he noted, yet the physical footprint of the transmission system cannot grow fast enough to keep pace. By replacing ACSR Hawk with ACCC® Hawk, PGCB sharply increased the capacity of its Barisal and Saidpur – Purbasadipur 132 kV corridors – jumping from 646 amps to 852 amps per circuit – while controlling thermal sag and avoiding tower reinforcement. The composite core’s lighter weight, coupled with its ability to operate safely at higher temperatures, allowed PGCB crews to upgrade aging assets without overloading structures or expanding rights-of-way. The photographs he shared of the field crews at Barisal and Saidpur made the scale of the effort unmistakable: this was practical modernization, executed under tight timelines and challenging conditions.
Berger’s presentation traced a parallel story from a very different landscape: the fast-growing Lower Rio Grande Valley in Texas. A decade earlier, a severe winter storm exposed how vulnerable the region had become as peak load outpaced the capabilities of its legacy 345 kV lines. AEP faced a fundamental choice – build new infrastructure or find a way to double the capacity of what already existed. Berger explained how deploying CTC Global’s ACCC® Conductor allowed AEP to reconductor live, maintain system reliability, and complete the work roughly nine months ahead of schedule. The benefits were immediate and measurable: sharply reduced line losses, substantial CO₂ reductions, and a strengthened backbone that has operated without issue ever since.
While the technical details differed between Bangladesh and Texas, the underlying lesson was unmistakable. Advanced Conductors are no longer exotic materials reserved for unique circumstances; they are becoming core infrastructure for utilities that must adapt quickly to both climate realities and new load dynamics. They enable capacity without expansion, resilience without reconstruction, and operational savings that accumulate year after year.
What UKEP made clear – through the voices of Berger and Rahman – is that the future of transmission will not be defined solely by new lines, but by smarter lines. And as utilities search for pragmatic ways to modernize systems under intensifying pressure, the World Bank’s commitment to facilitating this exchange of experience may prove as essential as the technologies themselves.
