Upgrading Power Grids to Accommodate Renewable Energy Is a Key Issue at Climate Talks
Officials say outdated grids are slowing renewable growth and requiring billions in new investment to keep solar and wind power flowing.
At United Nations climate talks in Turkey this week, organizers are pushing for ambitious goals to upgrade power grids, including the recently launched Global Grids Accelerator for Africa and Southeast Asia.
Outdated power grids, originally designed for fossil fuel plants, are failing to absorb renewable energy, creating a 'real bottleneck' that forces continued reliance on coal and gas, according to Oxford University's Jan Rosenow.
To meet 2030 electricity demand, the International Energy Agency calculates annual grid investment must increase by about 50% from today's $400 billion, while China and India curtail massive amounts of renewable power.
The Association of Southeast Asian Nations is promoting an interconnected power grid to allow countries to trade electricity, with Abdul Razib Dawood of the ASEAN Center for Energy calling it a safeguard against future shocks.
Massive scaling up of grid investments is required to meet climate goals, said Selwin Hart, special adviser to the U.N. secretary-general, warning that infrastructure and storage development must accelerate to keep pace with the energy transition.
