The world must add or replace nearly 50 million miles of transmission lines in the next 17 years to allow countries to meet climate goals and achieve energy security, according to a new report by the International Energy Agency covered by CNBC.
What’s going on: The amount of transmission line needed—49.7 million miles—“is roughly equivalent to the total number of miles of electric grid that currently exists in the world, according to the IEA.”
- The undertaking “will require the annual investment in electric grids of more than $600 billion per year by 2030,” double current global investment levels in transmission lines.
- Countries must also make changes to the way they operate and regulate their grids.
Why it’s important: Investment in global transmission lines has not kept pace with the growing appetite for renewables, and without replacements and additions to transmission lines, power bottlenecks will become “ever larger.”
Growing gridlock—and demand: “There are currently 1,500 gigawatts of renewable clean energy projects in what the IEA calls ‘advanced stages of development’ that are waiting to get connected to the electric grid around the world.”
- Meanwhile, demand for electricity will only rise as more of the globe moves to electric power.
- But building new transmission lines takes time, owing to lengthy permitting processes—which is why the NAM has long advocated speeding the process in the U.S.
Our view: “The NAM has identified building additional transmission lines as a top priority for the next round of permit reform negotiations,” said NAM Vice President of Domestic Policy Brandon Farris.
- “We will continue to fight to break down barriers to building new projects, including manufacturing facilities, energy generation, transmission lines, bridges, roads and more.”
