The Power Construction Corporation of China (PowerChina) has started building a 220 MW solar PV power plant in the Biskra wilaya (northern Algeria), while a Chinese consortium of China Electricity and Water Company (CWE), Chinese Nuclear Industries Corporation (HXCC) and Yellow River Company for Consulting Engineering (YREC) has launched construction of an 80 MW solar PV project in the Ouled Djellal wilaya, located just south of Biskra.Both solar projects are expected for completion in 2025.

The state-owned China State Construction Engineering Corporation (CSCEC) began building a 300 MW solar power plant in Algeria’s Oued Province in March 2024 as part of the Solar 1,000 MW program. The project is slated for completion by late 2025 or early 2026.
Currently under construction in Biskra province, the 300MW solar plant is the first of eleven PV facilities planned under Algeria’s Solar 1000 programme, which aims to install 1GW of capacity across the country.
Building on the Solar 2,000 MW and Solar 1,000 MW programs launched by Algeria’s state-owned company Sonelgaz, which include a wide range of solar energy initiatives, the government aims to diversify its revenue streams and reduce reliance on natural gas, which is currently primarily used for power generation in the country.
The launch of the Biskra 300MW Solar Power Plant—the nation’s largest photovoltaic (PV) project to date—marks a major step forward in Algeria’s renewable energy ambitions.
The two photovoltaic projects have a capacity of 220 megawatts and 150 megawatts, respectively, and will be constructed by POWERCHINA using an EPC model. The two projects are parts of the 15 gigawatts photovoltaic network planned and constructed for Algeria by 2035.
Among them, the 233-megawatt photovoltaic project completed in 2016 was Algeria's first new energy project and also the first large-scale grid-connected photovoltaic power station project in Africa. It was honored with the Luban Prize for Overseas Projects in 2018-2019.

These include the signing and landing of the 20 GWh sodium-ion battery project in Suining, Sichuan; the Jinlongyu solid-state battery materials project in Huizhou entering the approval stage; the rapid construction of the 4 GWh lithium battery project by Hubei Yijia Tong Technology Co., Ltd. in Hubei; and the steady advancement of Gaiya New Energy’s 3 GWh large cylindrical lithium (sodium) battery base in Zhejiang.

The system collects and integrates the data of wind farms and decentralized wind turbines, and presents each turbine's power generation, output, operation status, power generation status, fault information and other important parameters from three levels: wind farms, wind turbines and components by Web page and cell phone APP, so as to monitor the operation of wind turbines anytime and anywhere.

Through handling large-scale plants, we have refined our remote monitoring technology to monitor equipment status and detect prediction using various sensors. Utilizing these technologies, human resources, and experience, we will develop comprehensive O&M services for offshore wind power generation facilities.
O&M (operation and maintenance) for offshore wind power generation is much more difficult than that for onshore facilities, and the impact of equipment failures will be greater and more critical. We have provided EPC and O&M services for various power generation facilities, including onshore wind power generation facilities.
Effective operation and maintenance (O&M) management is significant for enhancing the economic performance of offshore wind farms. Despite recent research progress in O&M, there remains a gap in integrating health prognostics and spare parts inventory into decision-making processes at the scale of offshore wind farms.
Moreover, in practical O&M for offshore wind farms, it is common for the original equipment manufacturer (OEM) or maintenance service provider to assume dual roles as decision-makers responsible for both maintenance planning and spare parts provision.
The O&M scheduling strategy of offshore wind farms refers to arranging appropriate maintenance tasks and power generation tasks according to the operating status, maintenance requirements, resource conditions, and other factors of wind farms, to improve the economy and reliability of wind farms.
Up to 30% of the total cost of wind energy is attributed to operation and maintenance (O&M) , , and maintenance activities and spare parts account for the largest portion (43%) of O&M for wind turbines .

This article will introduce in detail how to design an energy storage cabinet device, and focus on how to integrate key components such as PCS (power conversion system), EMS (energy management system), lithium battery, BMS (battery management system), STS (static transfer switch), PCC (electrical connection control) and MPPT (maximum power point tracking) to ensure efficient, safe and reliable operation of the system.
