Kalayaan Power Plant

Kalayaan Power Plant - Philippines, 1999-2004

 The Project is fnanced by IMPSA (Argentina) under BROT (B uilt, Rehabilitate, Oerate, Trans!er) Trans!er) agree"ent #ith $P% $ational Po#er %ororation&

 The Plant consists o! t he construction o! the ne# 'alayaan PSP Stage II #ith a caacity o! *+ M- re.ersible u"ing/generating units& The rehabilitation o! the t#o eisting %aliraya and Botocan hydroo#er lant o! 0 M- and 1 M-, resecti.ely, is also included in the !ra"e o! the %B' roject&

 The 'alayaan u"ed storage lant i s the frst o! this tye in the Philiines, built to ro.ide "uch needed ea2 o#er caacity to the 3u4on electric electric grid& The Project Project "a2es use o! the head a.ailable a.ailable bet#een the uer %aliraya reser.oir reser.oir,, o! +0 "illion "0 caacity, built in the 516s to !eed a traditional hydroo#er hydroo#er lant, and 3aguna de Bay, a huge huge natural lagoon o! brac2ish #ater& #ater& The frst stage, co""issione co""issioned d in *7+0, is e8uied e8uied #ith t#o *1 M- re.ersible re.ersible units& units&
