Alcad battery system provides life-saving power at Thailand’s Siriraj Hospital

High-performance nickel cadmium battery systems ensure continuity of power for uninterrupted care of important patients at Thailand’s leading hospital

Siriraj Hospital

Oskarshamn, Sweden, 17th of June  2020Alcad, one of the world’s leading manufacturer of advanced nickel cadmium battery solutions for standby applications, has supplied backup systems to support vital continuous electricity supply at Siriraj Hospital in Bangkok.

The hospital ordered the batteries through the Metropolitan Electricity Authority (MEA) of Thailand, which was delivering upgrades to the hospital substation.

MEA’s needed the Alcad nickel cadmium battery system to deliver power in two phases. First, it should deliver a burst of power to operate the hospital’s main switchgear and clear electrical faults. Second, it should provide stable backup energy over a longer period to support critical loads such as life-support and safety equipment.

MEA also stipulated that Sunton Intertrade, the electrical contractor, should oversee delivery of the new Alcad nickel cadmium battery system while the existing time-served installation remained live and in service. This objective was to ensure uninterrupted critical service, which was essential as His Majesty King Bhumibol Adulyadej of Thailand was receiving treatment as a patient of the hospital at the time.

“Alcad’s technical capabilities, outstanding reputation and optimized TCO (Total Cost of Ownership) helped us to win this prestigious contract at Siriraj Hospital. We supported the installation with extensive logistical planning and by using an expert team to deliver the on-site installation. These steps were essential to ensure continuous support for critical power and healthcare systems, both during the contract delivery and long after.” said Patara Soontornpokin General Manager of Sunton Intertrade.
