Key Takeaways
- Global power grids must nearly double in size, needing $24.1 trillion.
- Grid investments must surpass renewables to achieve net-zero emissions by 2050.
- China and India can defer major grid costs until after 2035.
What Happened?
BloombergNEF’s New Energy Outlook reveals that global investment in power grids must outpace spending on renewable energy to achieve net-zero emissions by 2050. The grid network needs to almost double to 111 million kilometers, which will cost about $24.1 trillion. This compares to $22.7 trillion required for renewable energy investments to meet the same goal.
BNEF analyst David Hostert emphasized the importance of grids, noting that annual global investment must reach two to three times the historical $300 billion per year from 2020 to 2023.
Why It Matters?
A robust and expansive grid network is essential for achieving carbon neutrality by mid-century and aligning with the Paris Agreement goals. Despite the focus on renewables, grids act as the crucial enabler for distributing this green energy efficiently. Without sufficient investment, renewable energy advancements could be hampered by bottlenecks in the power network.
Nearly half of the $24.1 trillion will be directed towards distribution networks for homes and businesses, followed by $9.6 trillion for high-voltage transmission and the rest for electric-vehicle charging infrastructure.
What’s Next?
Investment in power networks will unfold in two phases. The first phase addresses current bottlenecks due to the decentralized nature of renewable energy, extending into the 2030s.
The second phase, starting in 2035, will focus on new power demand and distribution grids for industrial centers like hydrogen electrolyzers. While the U.S. and Europe will spend significantly on maintaining and upgrading aging infrastructure, China and India can defer most replacement costs until after 2035 due to their relatively newer infrastructure.
