Narada High Temperature Battery Selected for UN Assistance Project

Recently, the Yemen Hospital power supply project funded by the World Bank and under the responsibility of the UN project office for general contracting, design and supervision was officially launched. The Narada HTB series high-temperature battery was selected by the United Nations project affairs to participate in the project with its superior high-temperature operation performance.

Yemen Power Situation

Aden, Yemen , located at the southwestern tip of the Arabian Peninsula, is the gateway to the Indian Ocean from the Red Sea. It is known as the maritime traffic hub of Europe, Asia and Africa. It is also a world famous port. However, the power situation of Yemen is weak. There is a shortage of power supply, the transmission and distribution environment is unstable, and residents use solar energy systems to solve the problem of lighting power, but they cannot meet the power supply requirements of important equipment such as Aden Hospital.


Power Assistance Project Completed

In order to meet the power supply needs of the two hospitals in Aden, the Hybrid Solar Systems Project funded by the World Bank and contracted by the United Nations project office was installed at Birth and Neotatal Care equipment at Al-Shaab Hospital and  the Dialysis Center equipment in the – Al Jamhoria Hospital. The smooth operation of the project will effectively improve the electricity consumption conditions of local hospitals. The use of solar energy system and high-temperature batteries can reduce the operating costs of hospitals. The stable power supply can not only ensures the normal operation of hospital equipment, but also provides better living conditions for patients.

Narada High Temperature Battery in Yemen

Yemeni Aden is a tropical desert climate. The hot season is from May to September every year, with an average maximum temperature of 41.8˚C, and the highest ever reached 45.7˚C,. It is a high temperature environment that ordinary batteries cannot adapt. Narada HTB series high temperature battery was selected by the UN project affairs to participate in the project due to its superior high temperature operation performance. Narada high temperature battery does not require air conditioning to cool down even in the high temperature environment of Aden in summer, which can effectively reduce system operating costs.
