Launch of World’s First Smart Energy Storage EN 8 Pro to Drive Clean and Intelligent Energy Transformation

On April 10, Envision Energy officially launched the world’s first intelligent energy storage system, the EN 8 Pro, in Beijing. This groundbreaking product is built on a large AI model and incorporates two intelligent agents: the Trade Agent for trading automation and the Grid Agent for network construction. The EN 8 Pro aims to facilitate efficient and autonomous interactions between energy storage systems and the electricity market, bolstering the transition towards a cleaner and smarter energy system.

The hardware foundation of the EN 8 Pro is a standard 20-foot container equipped with an 8MWh+ system. It features Envision’s advanced 700Ah+ energy storage cells, boasting a cycle life of up to 15,000 times. The system’s energy density reaches 541kWh/㎡, significantly lowering the cost per kilowatt-hour over its lifecycle.

The EN 8 Pro comes with several specialized AI models embedded within its trading agent. These models automatically integrate meteorological data, market information, electricity price curves, and load forecasts to make precise predictions of peak and off-peak electricity prices. For instance, Envision’s dedicated AI weather model enhances forecasting accuracy by 30% compared to traditional sources. Additionally, it improves the accuracy of renewable energy power forecasts. On the consumer side, the AI load forecasting model achieves an accuracy rate of over 97%.

By integrating power and load forecasts with multi-source information at both the station and provincial levels, the Envision trading agent can predict day-ahead and real-time electricity prices with over 90% accuracy, outperforming the industry average by 5 to 10 percentage points.

Based on these precise price forecasts, the trading agent automatically consolidates real-time equipment status information and local trading rule models to generate AI-driven trading strategies. This allows for automated reporting and control, as well as continuous optimization of trading strategies through post-trade analysis. The trading agent also connects trading, production, and operations, ensuring optimal revenue throughout the system’s lifecycle.

As the proportion of renewable energy increases, it is noted that a higher share of renewable sources will reduce system inertia, potentially impacting the safety and stability of the power system. High-frequency trading of large-scale renewables in the electricity market will introduce new steady-state and transient characteristics, leading to more voltage and frequency disturbances.

Envision Energy is at the forefront of integrating AI with network construction technology. Utilizing its proprietary GenGrid generative grid technology, they have upgraded to a network construction intelligent agent. This agent combines capabilities from the Galileo grid perception system, the Kongming weather prediction model, control algorithms, and trading agents. Driven by a dual engine of data and models, it autonomously develops network construction plans for precise grid formation.

The Envision network construction intelligent agent is equipped with self-perception, self-adaptation, and self-evolution capabilities. It can monitor multiple sources of data in real-time, updating core metrics like voltage, current, frequency, and harmonics within milliseconds. Through dynamic system adjustments and robust control, it achieves damping inertia coordination and seamless switching between strong, weak, and islanded modes. By constructing digital twin models from real-time operational data, it can optimize control strategies autonomously without human intervention.

As the proportion of renewable energy continues to rise, the significance of integrated solutions that combine AI and energy storage, termed “Storage +“, becomes increasingly apparent. In the electricity market, the combination of different generation curves can create greater revenue opportunities. Off-grid systems and source-grid-load-storage configurations are also emerging as crucial components of new power systems and energy frameworks.

Leveraging its intelligent energy storage systems and its systemic capabilities, Envision can provide comprehensive “Storage +” solutions, including wind-storage, solar-storage, and source-grid-load-storage systems. With its collaborative control hub, Envision’s intelligent energy storage can optimize transactions and resource allocation, enhancing overall profitability. It can also autonomously construct networks in off-grid and microgrid scenarios.

Envision Energy’s President, Tian Qingjun, emphasized that the integration of energy storage and AI is essential for the development of energy storage in the AI era. Envision’s intelligent energy storage systems can actively participate in market dynamics, automatically respond to price signals, and ensure efficient allocation of resources for system balance. Additionally, they can adapt to the random fluctuations brought by renewable energy, facilitating seamless interactions between human and machine, as well as dynamic coordination between machines and grids.

Energy storage is transforming into an intelligent component of the new power system and energy framework. As a fundamental unit of smart energy, it is addressing the challenges of integrating high proportions of renewable energy, ultimately contributing to the transition towards cleaner and smarter energy systems.

Envision Energy continues to lead technological advancements in the industry, promoting the application of energy storage globally. According to the latest statistics from the Zhongguancun Energy Storage Industry Technology Alliance, Envision ranks third in energy storage shipments both domestically and globally in 2024. Currently, Envision has participated in over 300 projects worldwide, delivering more than 30GWh of energy storage solutions, including major projects like the Jurong Island project in Singapore and the Wormald Green project in the UK, with backlogged orders exceeding 50GWh.
