LISINER Commissions Qijiang’s First Integrated PV-Storage Microgrid

Recently, the Chongqing Qijiang PV-ESS Integrated Intelligent Microgrid Project (7.43 MWp PV + 6.96 MWh ESS) developed by LISINER has been connected to the grid. As the first PV-ESS integrated project in the region, the power station realizes digital reconstruction of the energy system and provides a replicable green model for cost reduction and efficiency improvement in precision manufacturing and metal smelting industries.

Long-Term Partnership, Scalable Energy Solutions

The client enterprise is a leading magnesium alloy producer affiliated to a Fortune Global 500 group. As a strategic partner, LISINER has supported multiple subsidiaries of the group in intelligent energy upgrading and built a series of benchmarks for smart energy utilization in the metal industry. The partnership has explored a decarbonization path balancing economic efficiency and sustainability for high-energy-consuming industries.

Magnesium alloy precision machining imposes extremely stringent requirements on the stability and continuity of power quality, and production lines are highly sensitive to breaker switching surges and power fluctuations. The client enterprise partnered with LISINER to launch Phase I of the PV-ESS project in 2025. Following capacity expansion and upgrading, further capacity addition was carried out to scale up the PV capacity to 7.43 MWp.

The on-demand and dynamic capacity expansion model precisely matches the client’s energy demands at different stages of development, and demonstrates the high scalability of LISINER’s smart energy solutions.

High-Performance Systems for Resilient Production

The project adopts a total of 30 sets of LISINER YUANTELIU® distributed energy storage cabinets. Equipped with end-to-end safety protection from cell level to system level, the cabinets support long-term operation under complex working conditions. With an operating temperature range of -20 °C to 50 °C paired with intelligent liquid cooling temperature control, the system delivers stable power output and substantially improves overall system performance.

Calculations show the project can generate over 5 million kWh of PV power annually, with an annual energy storage discharge of approximately 3 million kWh. The PV-ESS integrated intelligent microgrid significantly optimizes overall energy costs. While greatly lifting the self-consumption ratio of green power and enabling peak shaving and valley filling, it achieves controllable energy consumption and maximizes asset value.

LISINER Intelligent Microgrid Solution

As a pioneer in green microgrids, LISINER microgrid solutions feature prominent strengths of flexible switching, multi-resource coordination, stable operation and easy replication.

Supported by the self-developed SESCLOUD digital energy platform, the system senses, forecasts and optimizes the operating status of PV generation, energy storage and production loads in real time to realize coordination among multiple distributed energy resources. Covering AC, DC and AC-DC hybrid coupling architectures, the solution supports large-scale deployment across diverse scenarios.

The system allows subsequent connection to virtual power plant platforms, with reserved interfaces and capabilities to participate in demand response, ancillary services and green power trading, helping customers advance toward digital operations of integrated generation–grid–load–storage.

As a pioneering initiative for Qijiang, Chongqing to pursue the Dual Carbon goals, the project sets an exemplary model for optimizing the energy mix of high-energy-efficiency industries in Southwest China.

Clean energy underpins green intelligent manufacturing, and smart microgrids bolster advanced productive capacity. LISINER will continue advancing toward a greener future and safeguard the high-quality development of China’s manufacturing sector.
