CHAPTER II A REVIEW CONDITION OF NATIONAL ELECTRICAL POWER
2.1 The Condition Demand on Electrical Power
The Indonesia economic growth currently required a reliable supply in energy including on electricity. The electricity need shall go increasing refers
to the economy growth and population. More increasing economy in a region shall result in increased consumption up in electrical power as well as. This
condition should be anticipated as early as possible for the supply in electrical power can be provided in sufficient as required in a better quality and good
price.

National rate consumption in electricity in Fig. 2.1 got increased about 8.99 in 2012, 7.33 in 2013, 5.74 in 2014, 6.11 in 2015 and about 5.46
in 2016. Per capita consumption 2010-2019 in figure 2.2.

Still, consumption rate existed on operation scope PT PLN Persero got a trend same decreasing growth, the consumption grew around 9.4 in 2010,
decreased into 7.3 in 20111, got increasing about 10.2 in 2012, then got decreased int0 7.8 in 2013 and decreased again into 5.9 in 2014. It is noted
that consumption per sector uses, got having decreased growth highest of consumption on industry. It is however not mean consumption go decreased,
its growth rate only tended decreasing. It is seemly on the rate of National economy growth got tendency decreased currently years. In addition, shortage
in supply on some region manly outside of Java Bali got impact to decreasing rate of consumption.
2.2 The Condition In Supply Electrical Power
The installed capacity of National electricity generating grew about 6.8 in 2010, increased about 16.4 in 2011, got decreased about 13.0 in 2012,
then decreasing into 6.7 in 2013 and still decreasing into 4 in 2014. The additional capacity of generating plant in total seemly highly relative but it got
18 not proportional in distribution, where on Java Bali region got sufficient supply
whereas almost region outside Java Bali got shortage.
