A Micro Hydro at PLTGU Priok

The massive advance of desalination technology seems to offer an answer to the clean water issue in north cost of Jakarta, where the power plants of PT. Indonesia Power are located. Priok Power Generation and O&M Services Unit (POMU), a subsidiary of PT PLN (Persero), manages 4 blocks of Gas and Steam Power Plant (PLTGU) operating 10 gas turbines and 4 steam turbines with total installed capacity of 2,723 MW and 6 Diesel Power Plants (PLTD) with a total capacity 101 MW.

In the power plant area, water distilled from saltwater is used for the units operational needs, fire-fighting system, domestic water, etc. The excess distilled water is then pumped back to the sea.

Since 2017, however, the excess distilled water has been used to power a micro hydro (PLTMH), and the generated electricity has been used to light up the office buildings and help meet the electricity needs of community hydroponic gardens in Sunter, North Jakarta.

"Previously, the excess of desalinated water was pumped back to the sea through an outfall with average discharge of 207.4 m3/h. Now, the potential energy from the desalination is turned into electric power by a micro hydro. The generated electricity is used to light up the office buildings, while some is saved in 12V 100AH battery to be used as electricity source for hydroponic gardens in Sunter area, North Jakarta," explained M. Syaifuddin, Senior Environment Officer of PRO POMU, when meeting the esdm.go.id team in Jakarta on Friday (20/6).

Syaifuddin went on to explain that the micro hydro offers potential energy saving equal to 6 kW-8 kW. The electricity is used to light up the "Priok Learning Center" building; some is saved in 12V 100Ah battery to power the community empowerment program and solve the food security challenge within the ring 2 area of PRO POMU in Sunter Muara via a program titled "Taman Hatinya Sunter", which carries on hydroponic business planting organic vegetable such as pakcoy, spinach, kale, lettuce, etc.

"Not only is it energy saving and environmentally friendly, the new, renewable energy stored in the battery helps the local communities to power the pump at the hydroponic gardens. As the plant operator, we'll support this program by ensuring the micro hydro reliability and carrying out periodic monitoring," added Raihan Muhammad, the operator of GT, HRSG & ST of BLOCK 3.

In fact, Raihan continued, during the Covid-19 pandemic when most people face life's hurdles, the micro hydro can still power people's activities and add their income. "Besides powering the hydroponics, the energy from the battery is used to make cookies and light up the production workshop," he said.

The electricity supplied by the battery has helped reduce production costs so that the local community can both save money and make more profit. The Mayor of North Jakarta had even expressed his appreciation during the Panen Raya, bumper harvest, which was held online on 12 May 2020. (IY)
