Zhengmei Group’s Yongyao Energy Storage Project Successfully Delivers Electricity
On March 20, after 100 days of intensive work, Zhengmei Group’s 33.3MW/100MWh Yongyao Energy Storage Project overcame various challenges and successfully passed all tests, confirming that all indicators met the required standards for successful initial power delivery.
Zhengzhou Yongyao Green Energy Co., Ltd., a wholly-owned subsidiary of Zhengmei Group, was established in November 2023. In line with Zhengmei Group’s strategic deployment, the company focuses on developing integrated new energy solutions that combine wind, solar, and storage technologies, marking a crucial step in the group’s transformation and development.
Yongyao Energy Company leverages resources from Zhengmei Group’s industrial buildings and rooftops, effectively utilizing the internal grid and large industrial loads. Following the principle of “overall planning and implementation,” the company focuses on developing photovoltaic projects as an entry point to actively promote integrated new energy industries, including solar power, energy storage, and wind power.
The 33.3MW/100MWh energy storage project at Dongfeng Power Plant is the first commercial energy storage project implemented by Yongyao Energy Company under the group’s directive. This energy storage system serves as a milestone demonstration of Zhengmei Group’s implementation of integrated wind and solar energy solutions. It provides a strong guarantee for the group’s diversified energy transition while ensuring reliable power supply for the mines.
This project aims to optimize electricity consumption for Zhengmei Group and its related coal and power companies by peak shaving and valley filling. To ensure the project is constructed to high-quality standards, Zhengzhou Yongyao Green Energy Co., Ltd. meticulously planned and publicly tendered the EPC project in November last year, following industry practices.
After several rounds of intense competition, Pinggao Group emerged as the winner due to its technological strengths, reasonable pricing, and convenient maintenance, securing a comprehensive turnkey project that includes design, construction, and equipment supply. Completing the engineering design, equipment manufacturing, and civil construction within a limited timeframe proved challenging. Pinggao Group developed a detailed advancement plan and set strict completion deadlines for daily tasks, ensuring that work was finished on the same day it was started.
To expedite progress, all team members, including designers, equipment manufacturers, technicians, and construction personnel, willingly forfeited holidays to push the construction timeline forward significantly. Notably, on February 26, when all equipment was installed, the installation team worked late into the night despite adverse weather conditions, including rain and snow.
Throughout the project, leaders from Pinggao Group’s Energy Storage Division frequently visited the site to offer guidance and resolve issues. They motivated on-site personnel and reinforced their determination to overcome challenges. During critical phases, especially on March 13, technical leaders worked alongside the construction team, sharing meals and long hours to address problems collaboratively and ensure the project’s progress, all while prioritizing safety to prevent accidents.
Pinggao Group’s commitment to addressing customer needs and concerns earned widespread appreciation from stakeholders, facilitating the project’s timely grid connection.
2025 CIES Energy Storage Conference Introduction
The CIES 2025 Energy Storage Conference is co-hosted by the Energy Storage Application Subcommittee of the China Chemical and Physical Power Industry Association, China Energy Storage Network, and Digital Energy Storage Network, with academic support from the expert committee of the subcommittee. The conference will feature an opening ceremony, expert presentations, and discussions on topics such as the integration of intelligent distribution networks with new energy storage, new power systems, and collaborative development of energy storage with large-scale renewable energy bases.
Additionally, the conference will cover international energy storage, ancillary power services, spot trading, and capacity markets, as well as specialized topics like industrial green microgrids and national energy storage standards. A series of research reports will be released, including the “2025 White Paper on the Development of China’s New Energy Storage Industry,” the “2025 White Paper on Industrial Green Microgrid Development,” and the “2025 Analysis Report on Energy Storage Project Bidding and Pricing.” The event is expected to attract over 60,000 attendees from government agencies, research institutes, grid companies, power generation groups, EPC contractors, system integrators, energy storage device manufacturers, project developers, investment firms, and international buyers.
Since its inception in 2011, the China International Energy Storage Conference and Exhibition (CIES) has been a benchmark for promoting high-quality development in the energy storage industry, facilitating over 500 billion yuan in domestic and international supply chain collaborations and assisting local governments in attracting investment exceeding 100 billion yuan. The upcoming exhibition will include various sectors such as energy storage system integration, power generation groups, electrical equipment, temperature control devices, and safety products, aiming to showcase cutting-edge technologies and practices in the energy storage field.
We welcome you to participate in the 15th China International Energy Storage Conference and Exhibition in 2025.
