TEMPO.CO, Jakarta - State-owned electricity company PT PLN expects that coal-fired power plant (PLTU) Jawa 4 to begin operations in May and September 2021. The power plant with a capacity of 2 x 1000 MW is being built in Jepara Regency, Central Java.
“PLTU Jawa 4 is expected to contribute in improving the interconnected power system in Java and Bali and will be connected to a 500 KV transmission line in Tanjung Jati-Tx Ungaran,” Energy and Mineral Resources Minister Ignasius Jonan told a press conference yesterday.
Jonan broke ground on PLTU Jawa 4 project on August 31. He confirmed that the power plant will enhance power supply to consumers and industries. “The PLTU project is part of the accelerated power plant development program with a total capacity of 35,000 MW.”
He explained that the government and PT PLN are aiming to establish 109 power plants, including PLTU Jawa 4. The project is signed under an independent power producer (IPP) scheme on 77.4 hectares of land. The construction phase is expected to be completed in 50-54 months, starting in April.
Tempo learned that PLTU Jawa 4 will adopt the latest ultra-supercritical (USC) technology that operates above the critical pressures and temperatures for water. The system creates equilibrium between gas and liquid, resulting in higher efficiency.
A power plant with USC technology is 8-10 percent more efficient compared to other coal-based power plants. Another advantage is it will need less coal consumption and create lower gas emission, making it more environmentally friendly.
