ROOFTOP SOLAR PV
Fears of losing revenues, PLN is perceived as unfavored of rooftop
solar PV
RUEN mandates 45 GW of renewables installed capacity by
2025, of which 6.5 GW should come from solar power plants.
Much of this target can be met with the development of rooftop
solar PV in the country.
The Regulation 49 stipulates that PLN will only compensate
65% of rooftop solar PV electricity exported into the grid.
Stakeholders see this as a setback for the rooftop solar PV
development in Indonesia and the regulation only aims to
prevent PLN from losing revenues as more consumers use the
system on their rooftops.
The fears of losing revenues, however, are unfounded. By
assuming there will be 1 GW of rooftop solar PV by 2020, we
calculated that PLN revenues will be only declining by 0.58%, a
negligible reduction compared to benefits it brings to the
country. When the new regulation is applied to the calculation,
PLN revenue is reduced by only 0.52%.

With the new net metering scheme is seen unattractive and the battery costs continue to decline, a system of rooftop solar PV with batteries will
become a more viable option for PLN consumers. When this happens, PLN is expected to see more rapid decline in electricity sales. PLN, therefore,
needs to consider this in its business plan or find new business models to mitigate the risk.
