The Dinglun Flywheel Energy Storage Power Station, the World’s Largest Flywheel Energy Storage Project, represents a significant step forward in sustainable energy. Its role in grid frequency regulation and support for renewable energy will help stabilize power systems as China continues to increase its reliance on wind and solar energy.
China has connected the world’s biggest flywheel system to its national grid. Built in the city of Changzhi, Shanxi Province, the $48m Dinglun Flywheel Energy Storage Power Station can store 30MW of energy in kinetic form, the Interesting Engineering website reports.
First-generation flywheel energy-storage systems use a large steel flywheel rotating on mechanical bearings. Newer systems use carbon-fiber composite rotors that have a higher tensile strength than steel and can store much more energy for the same mass. To reduce friction, magnetic bearings are sometimes used instead of mechanical bearings.
On October 30, it was publicly tested, alongside important state officials, such as Prime Minister, Edi Rama. The full rollout of 5G to consumers has commenced on November 26, 2024. As of August 2025, Vodafone Albania expanded its 5G coverage in Tirana, Durrës, Fier, Gjirokastër and in popular tourist destinations around Albania.
On October 16, 2019, AKEP gave the authorisation to test 5G networks on the 3600 MHz-3700 MHz frequency band. On October 30, it was publicly tested, alongside important state officials, such as Prime Minister, Edi Rama. The full rollout of 5G to consumers has commenced on November 26, 2024.
The regulatory authority for telecommunication in Albania is the Electronic and Postal Communications Authority. The company invested more than €1,415 million in Albania including investments in infrastructure, spectrum, regulatory fees, distribution channels, human resources etc.
Mongolia has officially activated its 5G mobile network, marking a major milestone in the country’s ongoing digital development efforts. The rollout fulfills a core objective set by the Ministry of Digital Development, Innovation, and Communications for 2025, reinforcing Mongolia’s ambition to build a more connected and inclusive digital society.
But with the plan of Communications Regulatory Commission of Mongolia that will allow the nationwide introduction of 4G mobile Internet technologies by approving licenses to use radio spectrum for 4G LTE service to Mobicom Corporation, Unitel, Skytel according to the first commission meeting in 2016 this problem should be resolved.
Unitel (GSM)- The No.1 ICT group in Mongolia who have the first and nationwide 3G/4G/5G network. Mobicom Corporation (GSM) – The first mobile operator. service resembling that of landlines, but uses technology similar to mobile phones.
According to research, 5G technology is estimated to account for 1-4 percent of Mongolia’s GDP by 2030, creating an economic growth of MNT 800 billion annually.” In Mongolia, 1GB of data costs an average of USD 0.6, which is cheaper than the world average of USD 4.2.
