Australia is one of the countries with the highest solar PV capacity in the world. The capacity of solar PV installed in Australia has reached 16,319 MW and 600 W per capita at the end of 2019, making Australia the country with the highest per-capita capacity in the world. The Australian Government has established policies, regulations, and budgets as commitments to support the achievement of the solar PV capacity. This paper reviews and analyzes policies, regulations, and funds in Australia from federal to state levels on the side of solar PV development. Analysis showed that policies and regulations supported by the suitability of the government budget have a consequential effect on increasing the capacity of solar PV to implement and realize renewable energy targets in Australia. Several policies aforementioned as Feed-in Tariff, RET, NSSP, and budgets that focus on R&D have a significant impact on increasing the capacity of solar PV installed. Thus, realistic targets that are phased in, structured policy and regulatory support, budget compliance, and continuous education to the public are essential aspects that could be adopted in Indonesia to accelerate the realization of the national solar PV capacity target.

Berdasarkan peramalan beban sistem Bali dari tahun 2012 hingga tahun 2021 dengan pertumbuhan 6.16% sistem Bali harus dapat menyuplai daya sebesar 1059.45 MW pada tahun 2021. Upaya yang dilakukan untuk dapat memenuhi suplai daya listrik sistem Bali hingga tahun 2021 dengan suplai tambahan daya listrik melalui Saluran Udara Tegangan Ekstra Tinggi (SUTET) 500 kV sistem interkoneksi Jawa-Bali. Rencana beroperasinya SUTET 500 kV di Bali perlu mempertimbangkan susut energi yang terjadi. Susut energi dipengaruhi oleh panjang SUTET yang dioperasikan. Analisa susut energi dilakukan dengan menggunakan analisis “Load Flow” dengan tiga skenario beroperasinya SUTET 500 kV. Skenario pertama SUTET sampai di GI Kapal, skenario kedua SUTET sampai di GI New Kapal dan skenario ketiga SUTET sampai di GI Gilimanuk. Skenario dilakukan pada kondisi beban tahun 2015 dan kondisi beban tahun 2021. Berdasarkan hasil analisis diperoleh susut energi terendah jika rencana SUTET dioperasikan sampai di Kapal dengan susut daya tahun 2015 sebesar 11.328 MW atau 1.4% dari suplai dan pada tahun 2021 susut daya sebesar 19.594 MW atau 1.8 % dari suplai. Dari susut daya tersebut dapat diperoleh susut energi tahunan saat SUTET 500 kV dioperasikan di Kapal tahun 2015 sebesar 68.47 GWh dan pada tahun 2021 susut energi sebesar 118.43 GWh. Sehingga dari hasil analisis tersebut skenario SUTET 500 kV beroperasi di GITET kapal merupakan skenario dengan operasi sistem yang optimal dan efisien karena susut daya dan susut energi yang terjadi sangat rendah.
