A simple upgrade could expand the US electricity grid

A straightforward solution could double the capacity of the U.S. electricity grid, enabling a more efficient transition to renewable energy.

Shannon Osaka reports for The Washington Post.


In short:

  • Replacing old steel power lines with new carbon-fiber ones can double the power capacity without building new infrastructure.
  • The new wires, which sag less under heat, could handle increased electricity demands from renewable sources.
  • Regulatory changes and federal goals aim to expedite these upgrades, addressing grid congestion.

Key quote:

“This is something that could be a triple win. A win for the electricity system, a win for utilities and a win for consumers.”

— Brian Deese, innovation fellow at MIT

Why this matters:

Upgrading existing power lines with advanced materials is a cost-effective and rapid solution to enhance the electricity grid's capacity. This approach supports the integration of renewable energy sources, crucial for combating climate change and meeting growing energy demands.
