“At least 3,000 gigawatts (GW) of renewable power projects, of which 1,500 GW are in advanced stages, are waiting in grid connection queues—equivalent to five times the amount of solar PV and wind capacity added in 2022,” the report noted.
“This shows grids are becoming a bottleneck for transitions to net zero emissions.”
While investments in renewable energy such as solar and wind power, electric vehicles (EV), and heat pumps have been “increasing rapidly”—almost doubling since 2010—the investment in power grids has remained “static” at around $300 billion annually, it said.
The 2015 Paris Climate Accords agreed to hold the global increase in average temperature to 1.5 degrees Celsius above pre-industrial levels. Delays in establishing the necessary power grid could put this target “out of reach,” the report stated.
IEA presented a “Grid Delay Case” scenario in which the modernization of existing power grids and the setting up of new grids don’t happen in a timely manner…
