Recently, the annual operational data for Envision's Yancheng Sheyang Energy Storage Power Station was released. As Jiangsu's largest energy storage facility, the 250MW/500MWh Sheyang Energy Storage Station has demonstrated outstanding performance since its grid connection on July 12, setting multiple provincial records. In terms of revenue, the station achieved an annual MWh income 11.7% higher than the provincial average, translating to an additional 21.3 million RMB over its full lifecycle per 100MWh compared to similar energy storage projects.
Sheyang Energy Storage Station is equipped with Envision’s smart transactional energy storage system, featuring fully in-house developed battery cells, PCS, BMS, EMS, and SCADA systems. The station is also integrated with the EnOS Energy Storage Integrated Production and Sales Management Platform, ensuring high safety, high performance, and intelligent operation. These capabilities have enabled Sheyang Station to outperform competitors in both Jiangsu's capacity guarantee and spot market scenarios.
In Jiangsu’s capacity guarantee market, new energy storage projects settle at fixed electricity prices, with higher-priced dispatches during peak summer and winter periods and lower-priced dispatches otherwise. During these peak demand periods, safety and performance are key differentiators for revenue generation.
Since its grid connection, Sheyang Station has undergone high-frequency dispatching tests, averaging two full charge-discharge cycles per day, with some days reaching three cycles, all with zero failures and a 100% grid dispatch response rate. The station recorded no safety incidents throughout the year, achieved 100% power availability, and maintained a 98.3% capacity availability rate, ranking first in Jiangsu in overall efficiency among large-scale (100MWh+) energy storage stations.
During the summer peak period, Sheyang Station set a provincial revenue record, earning 40 million RMB in just 40 days, with an average daily revenue exceeding 1 million RMB. Its monthly revenue was 30% higher than the provincial average, outperforming the second-place station by 15%, securing first place in both total station revenue and per-MWh income in Jiangsu.
At the end of 2024, Sheyang Station participated in Jiangsu’s sixth electricity spot market trial. In spot market trading, differences in trading capabilities can lead to significant revenue gaps.
Sheyang Station actively submitted bids and offers in electricity spot market trading, leveraging the AI-driven EnOS Energy Storage Integrated Production and Sales Management Platform. Envision’s smart transactional energy storage system enables AI-driven automated trading, adaptive compliance with Jiangsu’s spot market rules, and a higher-dispatch bid strategy. This resulted in 14-day settlement period earnings of 11.54 million RMB, which was 54.2% higher than the provincial average.
Since establishing its energy storage division in 2020, Envision Energy has adhered to the principle that "the essence of energy storage is trading", developing integrated hardware-software smart transactional energy storage solutions. These solutions are designed for real-time electricity market fluctuations, allowing for precise trading opportunities and maximum profitability.
Currently, all Envision-operated energy storage stations utilize this smart transactional energy storage technology, achieving superior revenue performance in various power markets, including Inner Mongolia (Western), Shandong, and Gansu. Across multiple case studies, AI trading strategies implemented with Envision's smart transactional energy storage have increased revenue by approximately 15-20% compared to traditional manual trading.
Recently, China’s National Development and Reform Commission (NDRC) and the National Energy Administration (NEA) issued a Notice on Deepening Market-Based Renewable Energy Pricing Reform to Promote High-Quality Renewable Energy Development. This policy aims to fully integrate renewable energy into electricity markets, shift price formation to market mechanisms, and eliminate mandatory energy storage allocation requirements. Additionally, the NEA’s 2025 Energy Work Guidance outlines plans to achieve full coverage of provincial electricity spot markets by 2025.
Envision Energy believes that recent policies in the renewable energy, energy storage, and electricity markets will accelerate the transition of energy storage into a value-driven phase. Energy storage will shift from "built but underutilized" to high-frequency dispatch, introducing new safety challenges. Electricity market trading will become the primary revenue source for energy storage, and performance and trading capabilities will significantly differentiate profitability among energy storage projects, driving the industry toward survival of the fittest and sustainable development.
Moving forward, Envision Energy will continue to advance full-stack technological innovation, ensuring higher safety, better performance, and lower levelized cost of storage (LCOS). The company will also enhance intelligent trading algorithms to optimize energy storage profitability across its lifecycle, providing customers with "stable and profitable" energy storage solutions in the evolving market environment.
