Overview
During the 9th China International Import Expo, at a China-Finland high-end equipment cooperation forum hosted by the Lingang Group, Wärtsilä Qiyao and Lingang Green Innovation signed an agreement to build the Lingang area’s first integrated “diesel-storage-solar-charging” (柴储光充) industrial green microgrid demonstration. Aligning with the 2026–2030 Industrial Green Microgrid Guidelines issued earlier this year by five ministries, the project centers on four elements—diesel, storage, solar and charging—using Wärtsilä marine-engine test generators as the core dispatchable resource, complemented by storage, distributed PV and charging infrastructure, achieving source-storage-load coordination via power forecasting and optimal dispatch.
The project is a frontier practice in on-site industrial waste-energy utilization, sharply cutting unit-product energy consumption and supporting Lingang’s national zero-carbon park and “Zero-Carbon Bay” goals. From “exhibitor” to “investor,” Wärtsilä Qiyao has attended four consecutive CIIEs, now upgrading from technology showcase and trade to industrial investment and ecosystem co-building.
Background & Interpretation
1. Industry and Policy Context
Under dual-carbon goals, the energy sector is shifting from single-equipment supply to digital, integrated energy services. The 2026 five-ministry guideline provides a top-level framework for park-level source-grid-load-storage coordination, encouraging diversified dispatchable resources for local green-power consumption and waste-energy use.
2. Drivers and Underlying Mechanism
The core is “multi-energy complementarity + intelligent dispatch”: diesel/gas generation as a backup dispatchable source, storage smoothing volatility, PV supplying green power and chargers absorbing flexible load, all optimized by forecasting algorithms. The mechanism turns scattered energy assets from passive consumption into active regulation, raising park self-sufficiency and resilience.
3. Market and Industry Implications
As a national heavy-equipment and foreign-invested manufacturing hub, Lingang is becoming a proving ground for green microgrids. Finnish leaders like Kalmar and Konecranes have expanded locally, turning decarbonization from compliance cost into a location advantage. The microgrid chain—storage cells, PCS, PV modules, EMS and gen-sets—offers broad localization synergy.
Implications & Outlook
Near term, the demo will validate the economics and decarbonization effect of the diesel-storage-solar-charging model in high-end manufacturing. Medium term, as the guideline rolls out and zero-carbon-park policy advances, industrial microgrids may scale from isolated pilots to replication. Key variables: payback period, storage cost curve, and breakthroughs in green-power-direct-connection and wheeling-price mechanisms.
Takeaways for Industry Participants
Equipment makers can couple waste-energy gensets with storage and PV to offer “dispatchable-resource-as-a-service.” Park operators should build source-grid-load-storage platforms early to attract tenants with green energy. Energy-service firms must accumulate industrial-scenario algorithms and O&M know-how to capture the microgrid integration high ground.
