Deep dives

The Economic Imperative of Transmission Expansion

The construction of electricity transmission lines is essential for lowering energy costs and facilitating the access of renewable energy sources to urban demand centers. As renewable energy is often located far from where people live, building adequate transmission infrastructure is critical to transport this power efficiently. Furthermore, integrating a robust transmission network enhances grid resilience against natural disasters and allows for better use of the most cost-effective power plants. Failure to do so can lead to substantial economic losses, as seen in recent years where $2 billion in excess costs arose from transmission constraints in the grid system.
