The 64-year old PT Perusahaan Listrik Negara (PLN) is Indonesia’s state-owned power company. With around 38 million customers across the country, it has always been in the lookout for new technologies that will help it maximize its productivity and achieve cost efficiency. As one fourth of its 40,000 workers using Microsoft products, it has also been a major Microsoft customer in Indonesia. When Microsoft® Indonesia Open License Program offered it an opportunity to test drive Windows® Vista, PLN’s IT team, under the leadership of Mawardi Mansoer, Assistant Deputy Director, IT Infrastructure Strategy, saw it as an excellent opportunity to determine whether the new features in Vista would benefit its sprawling operations. Their experience convinced them that the new operating system would boost their efficiency and productivity.
Through its three business units, PT Perusahaan Listrik Negara (PLN), Indonesian state electricity firm, generates, transmits and distributes electricity to around 38 million individual and industrial customers throughout Indonesia. However, it generates 80 percent of its revenues in Jawa and Bali. Every year, it has to struggle to meet the country’s rising demand for electricity, which grows by five percent on average. Currently, it has 25,000 MW of installed capacity, but the actual output is far less than the installed capacity due to its ageing plants. Almost one third of the plants use diesel fuel, making the company vulnerable to the fluctuation in global oil prices.
||Our goal is to achieve maximum efficiency in every aspect of our business. That is why we always search for new business enabling technologies and products, including information systems.

As the bulk of its business comes from customers in Jawa and Bali, it is understandable that its IT implementation is most advanced in these two regions. For example, PLN already uses fiber optics networks to connect the branch offices in these regions, while in the outer islands it is still using MPLS, VSAT and dial-up connections.
The core application at PLN is a Customer Information System (CIS), which handles customer billing and services. In addition, PLN has also implemented SAP R/3 ERP, complete with employee self-service of the HR module. Communications at the management level already relies on e-mail, Microsoft® Office SharePoint® Portal Server 2003, Microsoft® Office Communicator 2007 and video-conferencing.
Because of the skyrocketing fuel prices in recent times, coupled by rising infrastructure maintenance costs and operational costs, PLN has been under tremendous pressure to find ways to maximize its efficiency and boost employee productivity. Like other companies in similar industries, effective use of IT is one of the solutions that PLN has to look at seriously. More specifically, the company had to find ways to enable its management and employees to achieve more in shorter periods of time.
From time to time, the House of Representatives or the government may summon the company’s management for a hearing. Therefore, it is also very important for PLN to have the most current data available at any time.
PLN has been progressive in adopting new technologies. The IT team, led by Mawardi Mansoer, Assistant Deputy Director, IT Infrastructure Strategy, PLN, has the task of testing every promising IT product that it comes across to see whether they can use them to improve the company’s overall performance. In addition to the three business units, the team is also responsible for the IT systems and infrastructure in all PLN’s subsidiaries. They are also in charge of standardizing all the applications used by the companies, some of which are still self-developed using outdated programming languages. “We are always searching for the right enabling technologies for our business,” says Mawardi.
About one fourth of PLN’s 40,000 employees use computers, both desktop and mobile. Some are still using Microsoft® Windows® 98 because of hardware limitations. Others are still using the older version of Windows because they run applications that have not been updated to run on newer versions. All of the employees also use Microsoft® Office in their daily work.
The extensive use of Microsoft products places PLN on the list of Microsoft major customers in Indonesia. When Microsoft Indonesia Open License Program offered the power company an opportunity to test drive Windows® Vista, Mawardi and his team immediately accepted it. “We believe that new versions will have new and improved features, which will help us in our job,”
Mawardi explains. Mitra Integrasi Informatika (MII) helped PLN with the deployment of Vista at PLN’s Head Office and some of its divisions. Currently, the IT Division, HR and Finance departments are already using Vista while in the branch offices, the new operating system is used mostly by IT staff.
Currently, Vista is still in the evaluation stage. Only the IT people and a select group of managers are using it. “Although we have used only some of the new features, we have already enjoyed significant benefits of Vista, and it will become part of our IT”, says Mawardi.
PLN immediately saw multiple benefits offered by Windows Vista, including improved security through BitLocker™, faster search, simplified folder management, improved power management, more accessible user interface and quicker synchronization between computers and mobile devices.
BitLocker, which is an add-on to Vista Enterprise or Vista Ultimate, helps users encrypt their hard disks so that confidential data will not fall into the hands of the unauthorized. “In most cases, people’s awareness of the need to protect their data is still very low. This tool helps us make them recognize of the importance of data security,” says Mawardi.
Windows Vista incorporates indexing, which allows users to search the entire system and find the documents they need in a matter of seconds. “Now I no longer have to create a complex tree structure of folders,” says Mawardi. “All I need to do is create three folders that I call, for example, Archive, Current and Action. No matter in which folder the documents are stored, I can find them instantly,” he adds.
Improved Energy Consumption
Energy consumption is a major issue nowadays. Therefore, the ability to manage power usage in a notebook is a significant addition. “Besides, it also helps us use our batteries longer,” says Mawardi.
Intuitive User Interface
The user interface in Microsoft® Internet Explorer® 7, for example, has been redesigned with user-friendliness in mind. “We can, for example, open new pages in the same Explorer window and move from one page to another by clicking on the tabs,” says Mawardi. In addition, it is also much easier to find the answers to the questions that the users may have.
“The new Help in Windows will instantly provide us with the instructions on how to do the things we want to do,” he adds.
Seamless Mobile Connectivity
With Vista, users can synchronize their data with their mobile devices much more easily and quickly. “The synchronization works seamlessly and saves a lot of time, especially as more and more of our management staff now use smartphones to continue their work while on the go,” says Mawardi.
“In addition, the Backup and Restore tools are now far more reliable than in the previous versions of Windows. Microsoft has also enhanced the Multimedia experience in Vista,” concludes Mawardi.
