The Current State of Wind Energy in Bulgaria: By the end of 2023, Bulgaria’s installed wind capacity reached 705 MW, accounting for 3.9% of the nation’s annual gross electricity generation. Wind farms in Bulgaria generated 1,584 GWh in 2023, marking a 5.9% year-on-year increase.
Bulgaria is paving the way for a resurgence in wind energy investment after years of stagnation, as detailed in a new study produced by business intelligence provider SeeNext, in collaboration with Gugushev & Partners Law Office.
The first solar plant, near Stara Zagora, is already operational, and two more solar plants will be built near Kyustendil and Vidin. The wind farm, situated in northeast Bulgaria, will set new benchmarks for innovation and efficiency in the region.
Investor interest is especially high for locations in Bulgaria’s south and northwest. The news outlet highlighted the Tenevo hybrid project in Yambol area in the southeast. Eurowind Energy and Renalfa IPP started the construction of a 238 MW solar power plant there in 2023.
"We will strive to build the Hainan Free Trade Port into an important gateway leading China's opening up in the new era, contributing to the sustained development of the Chinese economy as well as injecting stability and certainty into the world economy," said Yuan, assistant minister of commerce. ■
The Ministry of Commerce will make more efforts to support Hainan in aligning with high-standard international economic and trade rules, enhancing institutional openness, and fostering new growth drivers through targeted measures, Jiang said.

[Photo/Xinhua] The Hainan Free Trade Port will launch island-wide independent customs operations on Dec 18, a key step in transforming the tropical island into a globally significant free trade hub, a senior official announced Wednesday.
Vice Minister of Finance Liao Min noted that the number of duty-free items in Hainan will increase from about 1,900 to around 6,600, marking a significant boost in openness.
5G Outdoor integrated cabinet is well suited for power equipment, batteries, telecom gear, all integrated into a robust, economical package. The cabinet contains internal mounting rails, which allow installation of standard 19" equipment. Lockable front door with rubber seal ,with AC or DC Air conditioner mounted on the door Support custom-made.
Notably, China, Korea, and the US are vigorously engaged in this field, specifically related to the 5G network. This review paper identifies the possible potential solutions for reducing the energy consumption of the networks and discusses the challenges so that more accurate and valid measures could be designed for future research.
Despite their very low capital cost and high energy density (300-400 Wh/L), molten sodium–sulfur batteries have not achieved a wide-scale deployment yet compared to lithium-ion batteries: there have been ca. 200 installations, with a combined energy of 5 GWh and power of 0.72 GW, worldwide. vs. 948 GWh for lithium-ion batteries.
Due to the high operating temperature required (usually between 300 and 350 °C), as well as the highly reactive nature of sodium and sodium polysulfides, these batteries are primarily suited for stationary energy storage applications, rather than for use in vehicles.
The construction of a free trade port in Hainan can strengthen economic, trade and investment ties with BRI partner countries, especially ASEAN countries, enhance the level of opening up to the outside world and expand foreign trade.
"With the independent customs operations, Hainan FTP is poised to become a key gateway for China's new era of opening up and innovation," Cai added. China's Hainan Free Trade Port (FTP) is set to launch an island-wide independent customs operation on Dec. 18, 2025, underscoring the country's wider push for high-standard opening up.
Since the launch of the FTP initiative in 2020, Hainan has experienced a surge in foreign trade activities: Over 70,000 new foreign trade companies have been registered. These businesses have significantly contributed to the province’s growing role in international trade.
BEIJING, Aug. 8 -- China's Hainan Free Trade Port (FTP) is set to launch an island-wide independent customs operation on Dec. 18, 2025, underscoring the country's wider push for high-standard opening up.
Grid energy storage, also known as large-scale energy storage, is a set of technologies connected to the electrical power grid that store energy for later use. These systems help balance supply and demand by storing excess electricity from variable renewables such as solar and inflexible sources like nuclear power, releasing it when needed.
Energy storage cabinets are crucial in modern energy systems, offering versatile solutions for energy management, backup power, and renewable energy integration. As technology advances, these systems will continue to evolve, providing more efficient and reliable energy storage solutions.
An energy storage system (ESS) for electricity generation uses electricity (or some other energy source, such as solar-thermal energy) to charge an energy storage system or device, which is discharged to supply (generate) electricity when needed at desired levels and quality. ESSs provide a variety of services to support electric power grids.
Because power systems are balanced at the system level, no dedicated backup with energy storage is needed for any single technology. Storage is most economical when operated to maximise the economic benefit of an entire system. Don’t we need storage to reduce curtailment?
Fundamentally, the BMS maintains individual cell balance, tracks the state of health (SOH) and state of charge (SOC), and relays important metrics to external systems. Even the most sophisticated lithium-ion battery pack would be vulnerable to malfunctions and safety risks in the absence of a BMS. How Does a BMS Battery Management System Work?
The battery management system includes a battery control unit and multiple cell supervision circuits. The electronic disconnect unit serves as an all-in-one solution that integrates a battery disconnect unit, a battery management system, and optionally the cell monitoring units. based on volume production possible due to global production network
Centralized battery management systems utilize a single control unit that monitors and manages all cells in the battery pack through dedicated wiring harnesses. This approach offers excellent cost efficiency for smaller battery packs and provides centralized processing power for complex algorithms.
Cell balancing: Over time, the cells in a battery pack can become unbalanced, with some cells having higher or lower charge levels than others. A BMS can balance the cells by ensuring each cell is charged and discharged evenly, which helps maximize the battery run time.
