InfoSAWIT, JAKARTA – PT Perkebunan Nusantara (PTPN) II, the subsidiary of PT Perkebunan Nusantara Holding PTPN III (Persero) in the early of this year starts to supply the electricity to network system of PT PLN (Persero) in North Sumatera. The electricity derives from Biogas Power Plant (PLTBg) Kwala Sawit and Biogas Power Plant Pagar Merbau.
The Secretary of PT Perkebunan Nusantara Holding PTPN III, Irwan Perangin-angin said that the selling of electricity to PT PLN is done by Independent Power Produce (IPP) scheme. It derives from the renewable energy which is advantaging palm oil mill effluent (POME) from the liquid waste in the palm oil factory.
In operating the two biogas power plants, there has been cooperation in the operational and maintenance (O&M) with the subsidiary of PT Pertamina (Persero), PT Pertamina Power Indonesia (PPI).
“This is the synergy among the Enterprises and could be profitable for every side,” he said in the press conference which InfoSAWIT recently got.
Manager of Biogas Power Plant of PTPN II, Dedy Gurning said that the biogas alternative energy development from PTPN II is one program of energy security to increase the supply. “Alternative energy development, not include the geothermal, is the renewable energy in POME – base which derives from the liquid waste in the palm oil factory. The electricity from POME for thirty ton – of fresh fruit bunch (FFB)/hour – capacity could be equal to one megawatt of electricity per hour,” he said.
He thought that PTPN II as one enterprises in plantation within the palm oil as the main commodity processes it in the factory to produce crude palm oil and kernel.
“From the process in the factory, there are liquid wastes and the compound liquid waste (POME) has methane gas (CH4). Besides advantaging the electricity from POME, biogas power plant could deny the negative issues to the environment because of waste process which releases CH4 to the air,” he said .
The methane gas releasing in the air, he continued, should be captured and become the main material to the generator set. It could also be used to gas combustion in the boiler steam in the factory.
Meanwhile the Public Relation Coordinator of PTPN II, Sutan Panjaitan said that PTPN II has two units of biogas power plants based on the document of appointment published by General Directorate of New and Renewable Energy and Energy Conversion, Ministry of Energy and Mineral Resources (EMR) saying that PTPN II has project location plans as biogas power plant. The documents are No. 49/04/DEB.01/2014 on 10 February 2014 in PKS Pagar Merbau and No. 50/04/DEB.01/2014 on 12 May 2014 in PKS Kwala Sawit. The both have realibility run test and get operational certificate which General Directorate of Electricity, Ministry of EMR accredited.
He also explained that PT PLN has published the Commercial off Date (COD) to Biogas Power Plant Kwala Sawit and Pagar Merbau on 27 December 2019. The publication of COD means that both power plants could fully operate to supply and sell the electricity to PT PLN. (T2)
