GMC Chart, page-91

Before commenting you should actually know what you are talking about. Your travelling to Malaysia means ZIP, the only thing you have proved is that coal fired power stations producing electricity is expensive. I do not disagree with that. The PLN power station near GMC is coal fired and the new power being installed is diesel/gas.
If you think power is going through the roof you should be more concerned about Indonesian power prices as after 2019 election the power price will be considerably higher. Don't believe me, then google it yourself. PLN is losing money handover fist, the Indonesian Gov't are greatly concerned and aware. They do not want problems with the local population prior to the elections.
OM Sarawak is in Sarawak and doesn't use coal fired power, it uses hydro power and all the power requirements are locked into a 20 year contract for power usage. The price for the power contract is currently set in 2018 at 0.14sen/KWh or US$0.034/kWh and in 16 years time in 2034 it will 0.1784 sen or US$0.043/KWh.

"With OMH such low profitability I think u better consider to divest OMH and join GMC"
What are you smoking? OM Sarawak has the cheapest power in SE Asia and the only other alloy plant in the world with cheap power isNorway again using hydro power. You'd better checkout OMH Financial report next week before you make such foolish and uninformed comments.
