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 .

DTEK, Ukraine’s largest private energy company, has selected Fluence Energy B.V., a subsidiary of Fluence Energy, Inc. (NASDAQ: FLNC) (“Fluence”), a global market leader delivering intelligent energy storage, operational services, and asset optimization software, to supply Ukraine’s first large-scale battery-based energy storage portfolio.

Sept. 10, 2025. (Bohdan Nazarenko/DTEK) Ukraine’s biggest private energy firm, DTEK, has launched a major battery storage facility that will bring power to hundreds of thousands of homes and strengthen the grid ahead of expected Russian attacks this winter, the company said.
The €140 million total investment aims to enhance power grid stability, bolstering Ukraine’s energy security and independence. The project will be the biggest operational energy storage portfolio in Eastern Europe at the time of commissioning.
Together, they will store up to 400 MWh of electricity – enough to supply two hours of power to 600,000 homes (equivalent to roughly half the households in Kyiv).
"Despite the war, we invest in Ukraine’s recovery and growth. Our energy sector, having withstood countless Russian attacks, now gains new momentum," owner of DTEK and Ukraine’s richest man, Rinat Akhmetov, said in a press release.
The batteries are spread out across six undisclosed locations in Ukraine, which helps de-risk the projects from Russian attacks compared to a centralized system, Julian Jansen, managing director covering southern and eastern Europe at Fluence, said during the briefing.
