Potensi gas CBM di Kalimantan Tengah dapat digunakan sebagai pasokanbahan bakar pembangkit PLTGU namun belum adanya standarisasi harga jual gasCBM menyebabkan nilai keekonomian dari pembangkit berbahan bakar CBMperlu dikaji khususnya untuk harga produksi listrik yang cukup sensitif terhadapharga bahan bakar.Dalam perencanaan pengembangan pembangkit di Pulang PisauKalimantan Tengah akan dibangun pembangkit berkapasitas 2 x 60 MW, denganmemperhatikan produk pabrikan yang ada maka pembangkit yang dipilih adalahpembangkit berkapasitas 2 x 64 MW dengan total kapasitas 130,7 MW.Evaluasi pembangunan pembangkit PLTGU 130,7 MW dilakukan untukmenentukan harga produksi listrik dari kegiatan pembangkitan menggunakancadangan CBM yang ada. Evaluasi akan dilakukan dengan analisa sensitifitasharga listrik terhadap perubahan harga gas CBM dan nilai IRR. Harga listrik akandibandingkan dengan pembangkit PLTD, PLTU dan PLTGU Konvensional.Berdasarkan perhitungan dalam model finansial didapatkan kenaikan harga gas 1US$/Mmbtu, harga listrik akan naik 0,007 US$/KWh. Untuk harga gas CBM7US$/Mmbtu pada base case IRR sebesar 14% Interest Rate 10% didapatkanharga listrik PLTGU sebesar 0,083 US$/KWh.Pada kondisi base case harga listrik PLTGU dengan CBM mampubersaing dengan PLTD. Meskipun lebih rendah, harga listrik PLTU akan jauhmeningkat jika eksternalitas dimasukan dalam komponen biaya. Dan keterbatasanbahan bakar gas yang menyebabkan harga listrik PLTGU tinggi dapat ditekandengan memanfaatkan gas CBM sebagai bahan bakar alternatif.

CBM gas potential in Central Kalimantan can be used as a combined cycle

power plant fuel supply, but the lack of standardization of CBM gas price led to

the economic value of the CBM-fired plants need to be studied in particular for

the production of electricity prices is quite sensitive to fuel prices.

In planning the development of plants at Home Knives Central Kalimantan

plant will be built with a capacity of 2 x 60 MW, taking into account the

manufacturer's product then selected plants are plants with a capacity of 2 x 64

MW with a total capacity of 130.7 MW.

Evaluation of 130,7 MW Combined Cycle Power Plant construction is

done to determine the price of electricity production from generation activities

using existing CBM reserves. Evaluation will be conducted with sensitivity

analysis to changes in electricity prices CBM gas prices and the value of IRR.

Electricity prices will be compared with diesel generators, combined cycle power

plant and Conventional. Based on the calculation of the financial model obtained

gas price increase 1 U.S. $ / MMBTU, electricity prices will go up 0.007 U.S. $ /

kWh. For CBM gas price 7US $ / MMBtu in the base case IRR of 14% Interest

Rate 10% Combined Cycle Power Plant electricity prices obtained for 0.083 U.S.

$ / kWh.

In the base case conditions with CBM CCGT electricity prices competitive

with diesel. Although lower, the price at the plant will be much improved if

externalities are included in the cost components. And limitations of the fuel gas

combined cycle causing high electricity prices could be reduced by utilizing the

CBM gas as an alternative fuel.
