PV and energy storage manufacturer LONGi has signed a 1 GWh energy storage strategic partnership with power grid equipment manufacturer Zhongtian Technology (ZTT). LONGi says it is the first commercial deployment of its recently unveiled LONGi ONE integrated solar-plus-storage strategy (see China Solar PV News Snippets).
Launched earlier this month, the LONGi ONE framework is based on native integration of 5S technologies, including BMS, ICCS, EMS, TMS, and PCS, to support end-to-end energy management from generation to consumption. Under the agreement, LONGi will provide integrated solutions covering solar modules, energy storage systems (ESS), and lifecycle operations and maintenance (O&M) to support coordinated power generation, storage, and utilization.
SCEGC Investment Group, a provincial investment group in Shaanxi, plans to build a 1 GW PV power project in Manas County, Xinjiang, with a total investment of about RMB 2.38 billion and DC-side installed capacity of 1,069.36 MWp.
The project will adopt a grass-solar complementary model by deploying PV systems in desert areas while planting grass to restore degraded desert steppes, combining renewable energy generation with desertification control. The project is designed for an operational period of 25 years.
Shenzhen Gas disclosed in its 2025 annual report that its PV encapsulation material subsidiary Sveck recorded revenue of RMB 3.66 billion, down 3.33% year-on-year (YoY). It recorded a gross margin of 2.65% for the period, down 3.54 percentage points from 2024.
Solar encapsulant film sales totaled 794 million m² during the year, up 21.22% YoY, and the company ranked second globally in market share. As of the end of 2025, Sveck operated 4 production bases with an annual PV film capacity exceeding 1 billion m².
The Hainan Provincial Development and Reform Commission has issued a policy setting load factor standards and pricing rules for local renewable energy absorption projects, including integrated source-grid-load-storage facilities and zero-carbon industrial parks.
The policy sets the average load factor for transmission and distribution tariff calculation at 40.93% and requires an annual renewable energy self-consumption rate of at least 60%, aiming to standardize billing mechanisms and improve local renewable energy utilization.
In December 2025, Hainan issued a policy notice requiring at least 50% building PV coverage in zero-carbon industrial parks (see China Solar PV News Snippets).
