Things to Know from ESM

As an EPC engineer, updating new technology is a must to find new ideas for engineering design.

Luckily, there is quite a lot online seminar or webinar nowadays.

On June 24, 2020, I had a chance to attend the Energy Storage Modules Webinar held by ABB Indonesia or known as PT. ABB Sakti Industri.

The speaker was Tae Sho Shiin from Project Management of Energy Storage, ABB Korea.

Meanwhile, the moderator was Astrid Damayanti, Marketing Communications Manager of Electrification from PT. ABB Sakti Industri.

Below are some points from the webinar that I have concluded. If there is any point that needs to be revised, please let me know by comment below.

The Energy Storage Module is A Big Power Bank

When the first time I heard the storage modules, my mind was thinking of battery in the UPS or Uninterruptible Power Supply.

However, after following the webinar, I understand that ESM has a different function from UPS.

UPS uses the battery to provide backup energy. However, ESM is some kind of power bank that is used to support the supply of the electrical network.

ESM is large scale in MW but UPS is small scale in kW.

ESM is connected with parallel but UPS is connected with series in the network.

When do we need to use ESM?

As we know that ESM is some kind of big power bank. We can use it to by charging it for one period of time and use it at another time.

In industry, the peak power is during day time. If the lack of power supply, the ESM can be used to increase power supply.

In the night time, the ESM can be charged back.

Lifetime of ESM

The lifetime depends on the design. The degradation of battery capacity is 1-2%/ year. Another factor that needs to consider is the cycle of operation.

Professional Engineering Development with PII


Hi. Thank you for reading my first blog on this website. I have written a few posts in another blog but I will use this in English.

As an expatriate, I have limitations to increase my network with Indonesian professionals due to the distance. However, since the COVID-19 pandemic happened, the world and including Indonesia utilize teleconference for formal meetings or occasions. It means as a person who has constraints, I can create a relationship with more professionals, including with the one from Indonesia.

Professional Engineering Development with PII

Thanks to my cousin. Because of him, I encourage myself to pursue a professional engineering program after I spend almost 8 years of work as an engineer. I understand well that as an experienced professional, we need to be acknowledged. To do so, there is a path need to be taken. In the beginning, I joined Persatuan Insinyur Indonesia (PII) or The Institution of Engineers Indonesia. By joining this society, not only getting more knowledge but also getting known by others. It can be happened by attending webinars and joining the messaging platforms, such as Whatsapp group.

Based on Imam Prasetyo’s Blog, Persatuan Insinyur Indonesia (PII) history was begun on May 23, 1952. It was when Ir. H. Djoenda Kartawdijaja and Prof. Ir. R. Roosseno Soerjohadikoesoemo gathered with their Indonesian engineer colleagues. The meeting location was at Aula Barat, of Institute which is known as Institut Teknologi Bandung (ITB) now. At that time, Indonesia only had 75 engineers. Meanwhile, the responsibility to develop a newly-independent country was huge. Therefore, PII was established in order to strengthen cooperation among engineers to empower Indonesia’s development. In 1957, PII also became one of the driving motors of ITB establishment. In addition, PII is the second oldest professional organization after Ikatan Dokter Indonesia (ID) or Indonesia’s Medical Doctor Society.


Back to our condition in 2020, This COVID-19 is surely a pandemic which has a very bad impact on our world. However, we have to keep moving with a new normal. Remote communication has become common things which make conferences, seminars, lectures, or another meeting can be held with attendees from all around the world at the same time. Therefore, it depends on us how to face this COVID-19. Being positive and being adaptive are the keys to survival.
