ARKANSAS, Nov 23 (Future Headlines)- A groundbreaking analysis by climate analytics non-profit TransitionZero reveals that investing in global grid upgrades is not only a crucial step in preparing for the surge in renewable energy capacity but could also yield savings of $3 trillion in the clean energy transition by 2040. This ‘first-of-its-kind’ analysis covers 163 countries, representing 99% of the global population. It underscores the significance of modernizing power grids to accommodate the imminent influx of diverse renewable energy sources, emphasizing the potential economic benefits and cost-effectiveness of proactive grid investments.

The research estimates that an extra $1.7 trillion in investment for transmission infrastructure may be necessary between now and 2040 to support the global clean energy transition. Implementing extensive grid upgrades and clean energy infrastructure could save countries collectively $3 trillion in capital costs associated with achieving net-zero targets.

Upgraded power grids could transform many countries into clean power exporters, leading to additional economic gains. The International Energy Agency (IEA) predicts the need for 1.5 terawatts (TW) of additional electricity transmission cables and grid upgrades over the next two decades.

The analysis compares the costs of building a global net-zero power system under optimal transmission expansion against constraints on transmission and interconnector deployment (business as usual scenario). TransitionZero calculates the $3 trillion savings based on the difference in costs between the two scenarios, showcasing the economic advantages of prioritizing grid upgrades.

Matthew Gray, CEO and co-founder at TransitionZero, highlights grid modernization as a “blind spot of the net-zero transition,” emphasizing the critical need for open data and timely infrastructure development.

Gray underscores the urgency, stating that time is the main challenge, and any delay in grid investment decisions results in the construction of more expensive capacity, such as nuclear and biomass.
