Frequent blackouts and no sufficient backup possibilities
Although improving rapidly, unstable electricity as well as poorly maintained power backup equipment remains an ongoing problem in Indonesia. On 2 January 2018, Jakarta was hit by a major blackout during the morning rush hour, lasting as long as three hours in certain areas. Hundreds of thousands homes, businesses and commuters were affected as commuter train services leading into Central Jakarta were stopped due to the blackout.
National examinations halted due to blackouts
Another blackout incident that took place on 25 April 2018 at the Al Falah junior high school in Depok, West Java, caused panic as students who were undertaking the UNBK computer-based national examinations at the time were stranded and in the dark. The blackout started 20 minutes after the start of the examination and lasted for more than one and a half hours. Similar incidents occurred in April 2017 affected students across the country. In the Kendal regency in Central Java, over 11 high schools suffered a number of power outages while the UNBK computer-based national examinations were held. Even schools which rented diesel generators like the Kelua State High School in Tabalong, Kalimantan were affected, as the servers took over 15 minutes to bring back online after the generators were started.
Every millisecond counts
In sensitive, mission critical applications, power disruption events lasting mere milliseconds are sufficient to cause disruption to crucial systems such as a hospital's diagnostic imaging equipment, a bank's central server system, or a mobile operator's networks.
One company seeking to prevent this from occurring is Astra Graphia Information Technology (AGIT), a leading information and communications technology solutions provider in Indonesia and an Astra International subsidiary. While the AGIT team are intimately familiar with lead-acid battery Uninterruptible Power Supply (UPS) systems, they were looking for a solution that doesn't require a replacement of the batteries every 2 to 3 years—one of the multiple drawbacks of lead-acid batteries.
“Being prepared for everything is crucial in Indonesia”
“To keep your business running you have to be ahead with backup power. Being prepared for everything is crucial in Indonesia,” says Yakin Budi Wijaya Putra, Managing Director of PT Praptadaya Makmur Abadi, mentioned in regards to power security in Indonesia.
AGIT tested one of Ampd Energy's UPS products, the Ampd Silo P1 for nine months in one of their internal data centres, replacing an existing Merlin Gerin UPS. During this period, various grid voltage dips and spikes as well as a number of blackouts occurred. One of those events took place on 3 February 2018, when multiple blackouts happened between 13:04 to 14:16. During this period, the Ampd Silo provided continuous power and maintained a steady 220 volt supply to AGIT's data centre, which was entirely unaffected by the power disruption.
How AGIT found a way to be one step ahead
“I wanted to test something new, it sounded promising, but I still didn’t know what to expect. During this nine months trial period, the Ampd Silo gave AGIT 100% protection with no problems whatsoever,” says Wijaya, “We were happy with our decision to use the Ampd Silo to provide the ultimate form of power security to our customer's facilities. It provides a much longer runtime in a more compact footprint compared to conventional lead-acid UPSs and reduces the operating cost of AGIT's UPS by ninety percent.”
For AGIT's new, state-of-the-art Control Centre (pictured above), AGIT purchased a 20 kVA Ampd Silo P3 to provide a similar degree of power protection for over twenty devices used to monitor AGIT's operations, centrally.
With unstable electricity in Indonesia being an ongoing problem, the Ampd Silo series provides an ideal solution for facilities like AGIT's existing data centre and new Control Centre. As Asian society is more and more driven by technology, technology systems, which ensure security of power supply beyond what can be provided by grid utility companies, are increasingly an aspect of conducting business. Systems as the Ampd Silo provide one such alternative - an alternative with none of the drawbacks of existing lead-acid UPS systems or diesel generators.
