Paiton Extra High Voltage Substation is one of the large substations that serve transmission with a voltage of 500 kV in East Java, which gets electricity supply from PLTU Paiton of 4600 MW, for outgoing Paiton GITET also sends electrical power to Grati 1, Grati 2 and Kediri 1, Kediri 2 with a voltage rating of 500 kV. Based on the Decree of the Minister of Energy and Mineral Resources (ESDM) Number 0074.K / 21 / MEM / 2015 concerning the Ratification of the 2016-2025 Electricity Supply Business Plan (RUPTL), the load growth every year has increased. Therefore, there will be additional Generating Units with a capacity of 1000 MW at PLTU Paiton, it is necessary to analyze the effect of additional loads in 2017 - 2022 on the 500 KV GITET system before and after the addition of a 1000 MW generator. Based on the analysis, it is known that the additional power of 1000 MW will strengthen the Paiton GITET reserve margin in bearing the load growth, it can be seen from the reserve margin value before the addition of power plants by 16% and after the addition of 29%. For the ability of the Paiton - Grati GITET transmission line until 2022, the load is 62% with a power loss of 35.41 MW (2.85%) and the load on the Paiton - Kediri GITET transmission line is 62% with a power loss of 35.41 MW (2.85%) indicates that the channel still in good shape. In addition, the load condition for the IBT transformer until 2022 is 84%, it can be concluded that the transformer is in good condition.

When the pressure of an oil well is not too large to do Natural Flow, Artificial Lift is one of the methods that can be used to replace it, artificial lift usually using ESP (Electric Submersible Pump). ESP oil pump in petroleum is equipped with VSD (Variable Speed Drive) component to adjust motor speed as softstarter and oil rate regulator and as pump motor protection. For ESP construction with a motor tandem system installed on wells with different characteristics and depths that are different from ESP single motors. However, submersible pumps are augmented by increasing the number of pump stages according to the depth of the well by coupling, submersible electric motors can be mechanically coupled and electrically on a spindle between upper motor and center motor.
