Along the construction line of the Henan-Gu'an Expressway, an unassuming outdoor energy storage cabinet operates. As part of the project's temporary power supply, its presence ensures not only reliable electricity but also meticulously calculated efficiency. This energy storage project, developed by Easytop Group, is converting peak-off-peak electricity price differentials into a measurable monthly revenue of nearly 4,000 yuan.
EAST Focus: Infusing Green Energy Benefits into Highways
This project features a fully integrated outdoor cabinet energy storage system with a capacity of 100kW/215kWh provided by E-SITE. Since its commissioning, it has become a precision “efficiency unit” within the power system of the Gu-Wan Expressway project.
This system is not merely an assembly of components, but a deeply integrated solution featuring Yisite's proprietary 50kW PCS modules, a 215kWh high-safety lithium iron phosphate battery system, and intelligent BMS (Battery Management System) and EMS (Energy Management System). This integration ensures stable and efficient value creation within complex engineering environments.
EAST Smart Algorithm: Turning Peak-Valley Price Differences into Tangible Returns
The core innovation of the project lies in Yisite's precise execution of “peak-valley arbitrage” strategies through its intelligent energy management system. The system automatically charges during off-peak periods like nighttime or midday when electricity rates are low, then seamlessly discharges during daytime peak hours to supply construction loads.
This “buy low, sell high” model directly translates into quantifiable economic benefits. Field testing confirms the energy storage system generates an average daily profit of over 140 yuan, yielding an annualized return of nearly 47,000 yuan. This not only directly reduces the project's electricity expenses but also transforms what was once a cost center into an asset capable of generating positive cash flow, demonstrating Yisite's technological prowess in converting economic benefits.
EAST Full-Stack Capabilities: Delivering Certainty from Products to Trust
The project contractor, China Construction Seventh Engineering Division, selected E-SITE based on multiple factors of certainty. The decision was grounded not only in a clear revenue model but also in trust in E-SITE's comprehensive capabilities: “full-stack in-house R&D, efficient delivery, and worry-free service.”
Full-stack in-house R&D technical prowess: E-SITE insists on independent R&D of core technologies from PCS and BMS to EMS, ensuring high system synergy and long-term reliability.
Efficient Integration and Delivery Capabilities: The integrated outdoor cabinet design enables rapid “plug-and-play” deployment, perfectly aligning with the tight schedules and temporary nature of highway projects.
Nationwide Support Network: With 268 service centers across China, Yisite provides robust after-sales support, ensuring stable operation throughout the project lifecycle and eliminating all customer concerns.
Extending the EAST Solution: Empowering the Green Transformation of Infrastructure
The Guwan Expressway project stands as a successful case study of Easytel applying its mature energy storage solutions to traditional infrastructure. It demonstrates that even under complex operating conditions and limited construction timelines, Easytel's solutions can be rapidly deployed to deliver stable value.
This achievement stems from Easytop's deep commitment to its “AI + New Energy” strategy, which involves the seamless integration of hardware, intelligent algorithms, and specific application scenarios. Today, this capability is being replicated beyond expressways into broader “high-energy consumption, cost-sensitive” scenarios such as ports, mines, data centers, and zero-carbon campuses.
The value of every kilowatt-hour is defined by Yisite's smart solutions.
From meticulous management of every kilowatt-hour to cost reduction and efficiency gains in individual projects, Yisite Group has consistently embraced the concept of “low-carbon transformation,” actively contributing to the realization of the “dual carbon” goals.
In the application of energy storage technology, Yisite has not only achieved remarkable results in domestic projects but also continuously expanded application scenarios in the global market, driving the efficient development of the energy industry.
From industrial parks to transportation systems and urban power grids, Yisite delivers innovative energy storage solutions that help diverse industries reduce energy consumption and enhance efficiency during their transformation processes. The company consistently provides robust and reliable energy technology support for major national infrastructure projects and the development of the real economy.
