CBK Power Company Limited A partnership between two Japanese companies – the Electric Power Development Company Ltd. (JPower), a power wholesaler and power proect developer, and !"mitomo Corporation, an inte#rated b"siness enterprise both in Japan and overseas – the C$% Power Company Limited (C$% PCL) was created to implement the $"ild& 'ehabilitate&perate&rans*er ($') A#reement between C$% and the +ational Power Corporation (+PC). nder the a#reement, C$% plants will provide ancillary services and electricity *or +PC and will trans*er the plants to +PC at no cost at the end o* the cooperation period in --/. C$% PCL too0 over the operation o* the C$% Comple1 on 2ebr"ary 3, -4 and embar0ed on a comprehensive rehabilitation and "p#radin# pro#ram that aimed to e1tend the "se*"l li*e o* the three power #eneration plants in the power comple1, improve the plants5 available capacity, reliability and sa*ety, and also e1panded e1istin# p"mped stora#e power plant by addin# two more "nits.

n the sidelines o* a nat"ral #as s"mmit, !en. !er#e smena, chairman o* the Committee on Ener#y, said the C$% plants are now able to r"n by an additional > <7, reachin# *"ll capacity o* 3- <7 *ollowin# the ener#i@ation o* the L"mban line.
he +BCP has ener#i@ed the L"mban line so we will now have 3- <7 ( *rom C$%), he said.
9e said with > <7 added to the capacity o* C$%, which was r "nnin# at ro"#hly ; <7 prior to the ener#i@ation o* the line, the chances o* the L"@on #rid e1periencin# a blac0o"t have been diminished.
7ith that, we reall y lessen the chances o* browno"ts, smena said.
At the same time, he said it5s impossible to cate#orically say that there wo"ldn5t be blac0o"ts this s"mmer.

!till, he e1pressed optimism the power s"pply shorta#e in s"mmer wo"ld be mana#eable with power *rom both the C$% and the 8nterr"ptible Load Pro#ram (8LP).
7e may not have any blac0o"ts b"t i* we do, it5s in the peripheral areas and not the ind"strial or commercial areas, he said.
nder the pro#ram, bi# power "sers will "se their own power to ease demand *rom the #rid.
