China has formally issued its 15th Five-Year Plan for building a new energy system, setting a 2030 installation target of 300 GW for new energy storage and naming long-duration storage, sodium-ion batteries and flow batteries as priority technology pathways. The plan was issued on June 25, 2026, by the country’s top energy and macroeconomic planning authorities.
Policy visibility for flow batteries
The plan places long-duration and flow technologies alongside more established lithium-ion storage in national planning. According to MarketScope Live, the confirmed facts in the plan are limited but commercially meaningful, and the plan signals technology selection direction rather than detailed project mandates.
For flow battery suppliers, the inclusion matters because it gives the technology route stronger policy visibility. The reported facts do not set out project-level procurement rules, but they indicate that long-duration storage is being treated as part of the build-out rather than a niche add-on.
Export support measures
Alongside the 300 GW target, the plan strengthens export-related support measures. It encourages energy storage system integrators to pursue green power direct-connection certification and mutual recognition of international standards. The article stresses that this is a policy direction, not a confirmed mandatory execution path or detailed enforcement mechanism.
Even so, the direction raises the importance of certification readiness, test reports, standards cross-reference materials and bid documentation. For suppliers targeting overseas markets, those elements could become more visible in customer due diligence.
What it means for overseas buyers
MarketScope Live’s analysis says the plan may shift overseas importer supplier screening from price-first comparison toward review of technology route and certification readiness. Suppliers of long-duration storage, sodium-ion or flow battery solutions may need to review how those technologies are presented in quotations, technical submissions and qualification packages.
The policy gives these routes stronger visibility that could affect how overseas customers compare shortlisted options. It does not, by itself, confirm that every project will use long-duration or flow batteries, but it changes the planning context in which suppliers present their technologies.
The plan signals technology selection direction rather than detailed project mandates, according to the analysis.
