Telecommunications in Equatorial Guinea include radio, television, fixed and mobile telephones, and the Internet. no AM, 3 FM, and 5 shortwave stations (2001). 1 TV station (2001). The state maintains direct or indirect control of all broadcast media. The government owns the only national radio and television broadcast system, RTVGE.
This paper focuses on the modernization of the first national Mobile Network of Equatorial Guinea, called GETESA. Equatorial Guinea has three telecommunication companies: GETESA, Muni and Gecomsa. Getesa is the largest and the historical Equatorial Guinea telecommunication company established in 1987.
This paper focuses on the modernization of the first national Mobile Network of Equatorial Guinea, called GETESA. The government's decision to invest and take full control of the network was motivated by the lack of network quality, which had poor capacity, with 69% of the network coverage Received-Signal-Code-Power (RSCP) below 95dMm.
The Equatorial Guinea government did not respond to the AP’s inquiry about the island, its condition and internet access. Located in the Atlantic Ocean about 315 miles (507 kilometers) from Equatorial Guinea’s coast, Annobón is one of the country’s poorest islands and one often at conflict with the central government.
Vaal University of Technology, Vanderbijlpark, Sou th Africa. Abstract - This study gives a critical review of flywheel energy storage systems and their feasibility in various applications. Flywheel energy storage systems have gained increased popularity as a method of environmentally friendly energy storage.
A flywheel-storage power system uses a flywheel for grid energy storage, (see Flywheel energy storage) and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to serve as a short-term compensation storage.
A grid-scale flywheel energy storage system is able to respond to grid operator control signal in seconds and able to absorb the power fluctuation for as long as 15 minutes. Flywheel storage has proven to be useful in trams.
Application areas of flywheel technology will be discussed in this review paper in fields such as electric vehicles, storage systems for solar and wind generation as well as in uninterrupted power supply systems.

In Ontario, Canada, Temporal Power Ltd. has operated a flywheel storage power plant since 2014. It consists of 10 flywheels made of steel. Each flywheel weighs four tons and is 2.5 meters high. The maximum rotational speed is 11,500 rpm. The maximum power is 2 MW. The system is used for frequency regulation.
The city of Fresno in California is running flywheel storage power plants built by Amber Kinetics to store solar energy, which is produced in excess quantity in the daytime, for consumption at night. Intermittent nature of variable renewable energy is another challenge.
Flywheel energy storage systems are suitable and economical when frequent charge and discharge cycles are required. Furthermore, flywheel batteries have high power density and a low environmental footprint. Various techniques are being employed to improve the efficiency of the flywheel, including the use of composite materials.
However, the high cost of purchase and maintenance of solar batteries has been a major hindrance. Flywheel energy storage systems are suitable and economical when frequent charge and discharge cycles are required. Furthermore, flywheel batteries have high power density and a low environmental footprint.
