Meesha rakibidda ee ka hortagga kor u kaca shimbiraha:

Sababaha ugu waaweyn ee cilladda dhaawaca shimbiraha waa gariirka shimbiraha, wareegga gaaban ee walxaha madow ee buulka, wareegga gaaban ee jirka shimbiraha, iwm. Kuwaas waxaa ka mid ah, safarka khadka ee ay sababaan shimbiraha biyaha waaweyn sida qoyska Heron iyo qoyska gorgorka ee munaaradda ku yaal waa qiyaastii 90% cilladda dhaawaca shimbiraha ee khadka gudbinta, taas oo ah sababta ugu weyn ee safarka la xiriira khadka gudbinta shimbiraha. Wareegga gaaban ee walxaha buulka shimbiraha iyo albaabka wareegga ee ay keento wareegga gaaban ee jirka shimbiraha ayaa inta badan ka dhaca khadka qaybinta. Sidaa darteed, qodobka ugu muhiimsan ee ka hortagga dhaawaca shimbiraha ee khadka gudbinta waa in laga hortago dhaawaca shimbiraha ee ay keenaan shimbiraha waaweyn. Ka hortagga qaniinyada shimbiraha waa "irbad bir ah" oo lagu rakibay munaaradda. Ujeeddadu waa in laga hortago shimbiraha waaweyn inay ku dhaqaaqaan munaaradda, si loo gaaro yoolka ah in la baabi'iyo gariirka shimbiraha. Ka hortagga gariirka shimbiraha waxaa inta badan loo isticmaalaa in laga hortago gariirka khadadka gudbinta ee 110 kV ilaa 500 kV.
