1. Technological Breakthrough in Electrochemical Energy Storage System (ESS)

   CEEC’s ESS for the Andijan project adopts ​lithium iron phosphate (LiFePO4) battery cells with modular cluster design, each cluster providing 3.35MWh and a total capacity of 300MWh. The technology features high energy density (≥160Wh/kg), long cycle life (≥6,000 cycles @80% depth of discharge), and millisecond-level response, addressing Uzbekistan’s urgent needs for frequency regulation, peak shaving, and renewable energy integration.

   The ESS is equipped with ​liquid cooling thermal management, maintaining battery temperature within ±2°C through intelligent control. This ensures stable operation in Central Asia’s extreme temperatures (-30°C to 50°C), with overall system efficiency (AC-AC) exceeding 88%.

2. Integrated Grid-Side Engineering: End-to-End Infrastructure

• ​Booster Station & Transmission Network: The 220kV booster station utilizes GIS (Gas Insulated Switchgear) technology, reducing footprint by 40% with 99.99% reliability. The 6.1km double-circuit transmission line employs high-strength aluminum alloy conductors, minimizing line losses to below 2.5%.
• ​Smart EMS (Energy Management System): Powered by AI algorithms, the system predicts grid load and renewable generation in real time, optimizing ESS charging/discharging strategies to reduce renewable curtailment by 15%-20%.

3. Innovation in EPC Lifecycle Management

• ​Localized Collaboration: CEEC partnered with Uzbekistan’s National Electric Grid (NEGU) and local suppliers, achieving over 30% localized procurement to streamline logistics and reduce carbon footprint.
• ​Digitalized Construction: BIM (Building Information Modeling) and drone-based monitoring ensured precision in civil works and equipment installation across the 6-hectare site, cutting project timelines by 20%.
• ​Safety & Sustainability: The project meets UL9540A safety standards, integrates multi-level fire suppression systems (pack, container, and station levels), and uses recyclable battery materials, targeting a total lifecycle carbon reduction of 120,000 tons.
