ADB backs $70bn Asia grid

Electric grids are the unglamorous part of the energy transition — but they decide whether all those new solar panels, wind farms, and batteries can actually do useful work. Asia is adding clean power fast, but the wires between countries and even within countries have not kept up. That gap is what the Asian Development Bank is trying to hit with a new pledge announced on May 3 in Samarkand. The bank says it will back $70 billion of energy and digital infrastructure projects across Asia and the Pacific by 2035, with most of that aimed at connecting power systems across borders.

The other is a broader digital-connectivity push under what it calls the Asia-Pacific Digital Highway. The power side is the real center of gravity here — the bank say(adb.org)able power to move to wherever demand is highest. (adb.org) ### Why are grids the hard part? Because renewable energy is often built far from the cities and factories that need it, and because solar and wind output rises and falls through the day. A bigger, better-connected grid smooths that out. If one area has excess power and another is short, transmissio(adb.org)tment was holding back the region’s energy transition even as clean-energy spending surged. (adb.org) ### What does the $50 billion pay for? Mostly the boring but essential stuff — cross-border transmission lines, substations, storage, and grid digitalization. ADB also says the initiative can support generation tied directly to power trade, including renewable export projects, regional renewabl(adb.org)bout building the hardware and control systems that let multiple countries run a shared electricity network without constant instability. (adb.org) ### How big is the target? ADB’s 2035 goals are pretty concrete. It says the grid initiative aims to integrate about 20 gigawatts of renewable energy across borders, connect 22,000 circuit-kilometers of transmission lines, improve energy access for 200 million people, create 840,000 jobs, and cut re(adb.org)the rest from cofinanciers, including private capital. (adb.org) ### Where would this show up first? Not as one giant continent-wide grid. More like a stack of regional projects that eventually knit together. ADB says the plan builds on existing efforts in South Asia, the Bay of Bengal, Southeast Asia, and Central Asia. The clearest example is ASEAN, where the lo(adb.org)nched a financing initiative for that in October 2025. (adb.org) ### Why bundle digital networks with power grids? Because modern grids are software-heavy systems. They need sensors, communications links, forecasting, and fast control tools to handle variable renewable power. ADB is also making a separate bet that broadband and regional data links matter for grow(adb.org)ement looks like two sectors, but the logic is shared: cross-border infrastructure lowers costs and makes fragmented national systems more useful. (adb.org) ### What is the catch? Money is only one constraint. Cross-border power trade also needs aligned regulations, common technical standards, and political trust. ADB is setting aside up to $10 million in technical assistance for feasibility work and rule-harmonization because that soft infrastructure i(adb.org)is coordination. (adb.org) ### Bottom line This is a grid story disguised as a finance story. Asia already knows how to build renewable generation at scale. The harder task now is building the regional wiring — and the rules — that let cheap clean power move across borders instead of getting stranded where it is produced. (adb.org)
