The electricity generated from this system travels through a transformer, where voltage is "stepped up" or increased to 230kV or 400kV in preparation for its injection into the main power grid. Though electrical sockets in Singapore are supplied with only 220V to 240V of energy, "stepping up" the voltage is necessary to reduce energy loss as the electricity travels long distances.
After passing through the power plant's electrical substation, which acts as a monitoring point and safety switch in case of an emergency, the electricity enters Singapore's main power grid.
