[QUOTE="jarance, post: 186139, member: 21"] Power produced by power station are AC currect. Battery can stored only DC supply. There is no such device that can stored this excess energy. But the power station can be operated at 75% capacity with a spinning reserve of 25% for Coal and Oil Firing power Station. Unlike Gas turbine they can only operate at 100% capacity with 0% reserve. The spinning reserve can be utilised for PEAK load demand when office or factory come online. Previously, TNB have rely heavily on oil firing power station. Kapar was the first power station in Malaysia where it operated on triple fuel. i.e. oil, coal and LNG. This mean that which ever fuel is cheapest it can still operate. However, the supply of LNG supply by Petronas is not enough to operate Kapar power station continously. Hence the next cheapest fuel was coal as TNB also have a share in a coal mine in Indonesia. Oil of is out of the question because of the relatively high cost. Secondly, most of the Power station own by TNB are near its lifespan. It need to be rehabit or else it not worth operating its at it low efficiency. In fact, PD is now being rehab due to its expiry of its lifespan. Silimarly, plant like Connaght Bridge, Iskandar Power and Pasir Gudang power station are relatively old power station. They need to be decommisioned and rehab in stages and make way for the new and more effecient Power station. [/QUOTE]
