Critique:
-A huge part of the electricity will be wasted going through such a long way from source to destination of use.
-The estimated cost estimate of RM10b is conservative at best and will likely balloon over the years, just like the Bakun dam itself going many times over it's original estimated cost.
-The amount of money spent could be used for more power per ringgit projects elsewhere.
-The fact that highly polluting aluminum smelter industries are specifically invited to suck up the excess electricity just shows that this project did not take into account the state's demand level for power.
-Usually, the hundreds of kilometers along the pathway of the cables would open up new housing, commercial and industrial areas... but what can be built alongside it under the sea?
1) Sorry but, the losses wouldn't be as big as you've thought it'd be. Let me give you a bit of insight.-A huge part of the electricity will be wasted going through such a long way from source to destination of use.

On regular transmission lines, electrical power are transmitted in AC. Due to the inductance and capacitance in the line, there will be reactive losses.
However, when the transmission length is long (>500km), it will be converted to DC. In DC, due to the absence of frequency parameter, there won't be any losses due to reactive components. Real power loss will only come from the resistance of the line, which is very small compared to the distance in total.
2) & 3)
so is many of the government projects.4) I can sort of agree with this. TNB is paying alot of money to the IPPs for their power generation. But thing is, not all their power generated is fed into the national grid. Worse is that, some IPP are still being paid even though they did not generate electricity (it violates the law, but it's hard to detect)
So question is, do Peninsular Malaysia need that extra electricity?
5) Really? The way I see it, on-land transmission opens for squatters too.
