Abstract

Sektor ketenagalistrikan merupakan salah satu kontributor utama emisi gas rumah kaca (GRK) di Indonesia, sehingga diperlukan strategi pengurangan emisi yang terukur dan bernilai ekonomi. Penelitian ini bertujuan untuk mengevaluasi potensi carbon offset pada Pembangkit Listrik Tenaga Gas dan Uap (PLTGU) Gresik berkapasitas 1500 MW melalui inventarisasi emisi GRK, analisis posisi emisi terhadap batas emisi nasional, serta perhitungan potensi emission reduction (ER) dari skenario mitigasi. Metode penelitian menggunakan pendekatan deskriptif-kuantitatif dengan inventarisasi emisi berbasis aktivitas mengacu pada GHG Protocol, IPCC Guidelines, dan ISO 14064-1:2018. Emisi diklasifikasikan ke dalam Scope 1, Scope 2, dan Scope 3. Hasil perhitungan menunjukkan bahwa total emisi GRK PLTGU Gresik sebesar 2.311.282 ton CO₂e per tahun, dengan kontribusi dominan dari Scope 1 sebesar 2.310.910 ton CO₂e. Dengan produksi listrik tahunan sebesar 5.504.590,8 MWh dan batas emisi PTBAE 0,448 ton CO₂e/MWh, diperoleh Cap emisi sebesar 2.466.057 ton CO₂e, sehingga PLTGU Gresik berada di bawah Cap dengan surplus emisi sebesar 154.775 ton CO₂e. Analisis skenario mitigasi menunjukkan tambahan potensi ER sebesar 2.207–3.679 ton CO₂e per tahun dari pemasangan PLTS auxiliary (3–5 MW) dan 69.328–115.546 ton CO₂e per tahun dari penerapan hydrogen co-firing (3–5%). Total potensi ER yang dapat dicapai berada pada kisaran 226.310–273.999 ton CO₂e per tahun, yang berpotensi dikonversi menjadi carbon offset dan dimonetisasi melalui mekanisme perdagangan karbon. Penelitian ini menyimpulkan bahwa PLTGU Gresik memiliki peluang signifikan untuk berpartisipasi dalam skema carbon offset dan perdagangan karbon nasional melalui pengelolaan emisi yang terintegrasi, berbasis data, dan memenuhi prinsip measurement, reporting, and verification (MRV).

The power generation sector is one of the major contributors to greenhouse gas (GHG) emissions in Indonesia, thus requiring emission reduction strategies that are both measurable and economically viable. This study aims to evaluate the carbon offset potential of the 1,500 MW Gresik Combined Cycle Power Plant (PLTGU Gresik) through GHG emissions inventory, assessment of the plant’s emission position relative to the national emission cap, and estimation of potential emission reductions (ER) from mitigation scenarios. The study employs a descriptive–quantitative approach using an activity-based GHG inventory in accordance with the GHG Protocol, IPCC Guidelines, and ISO 14064-1:2018. Emissions are classified into Scope 1, Scope 2, and Scope 3. The results indicate that total annual GHG emissions of PLTGU Gresik amount to 2,311,282 tCO₂e, with Scope 1 emissions dominating at 2,310,910 tCO₂e. With an annual electricity generation of 5,504,590.8 MWh and a national emission limit (PTBAE) of 0.448 tCO₂e/MWh, the emission cap is calculated at 2,466,057 tCO₂e, placing PLTGU Gresik below the cap with an emission surplus of 154,775 tCO₂e. Mitigation scenario analysis indicates additional ER potential of 2,207–3,679 tCO₂e per year from the installation of auxiliary solar photovoltaic systems (3–5 MW) and 69,328–115,546 tCO₂e per year from the implementation of hydrogen co-firing at 3–5%. The total achievable ER ranges from 226,310 to 273,999 tCO₂e per year, which can potentially be converted into carbon offsets and monetized through carbon trading mechanisms. This study concludes that PLTGU Gresik has significant potential to participate in national carbon offset and carbon trading schemes through integrated, data-driven emission management that complies with the principles of measurement, reporting, and verification (MRV).
