Lessons learned from Brazilian’s Experience

CBS has reported that some blackouts in Brazil (in 2005 and 2007) were caused by some dirty works of bad hackers (see: http://www.wired.com/threatlevel/2009/11/brazil/). The recent massive blackout in Brazil might also the result of bad hackers. This happened two days after CBS reported the possible cause of blackouts in 2005 and 2007.

This has clearly shown that computerized system is very vulnerable to electronic attack. It has shown that total integration is very risky. The centralized software managed control system might be very efficient and also easy to monitor but it is also easy to be attacked. There is no perfect system made by mankind. There are always trade offs. In the case of Brazil, the trade off is easiness to be hacked.

Luckily the system in Indonesia might still very old and manual. No hacking system can do much harm to the system. A real “terrorist style” attack on transformer stations might do better. Moving to centralized software managed control system surely takes a lot of energy and resources and PLN has none of them.

Right now PLN is struggling to normalize power generation and distribution in Jakarta. Kompas reported that the scheduled blackouts might still happen until December. We are used to blackouts therefore we actually need an independent power source like for example personal solar powered electricity generator or “dreaming mode on” fuel cell powered electricity generator (like the one in Japan shown in Discovery channel) or anything like that.

Conclusion: since PLN’s financial condition is not yet very healthy, centralized software managed control system might still far from realization. If it were materialized, there should be a manual back up system so that if the software system fails, the manual system can still do the job.
