Nusa Penida Hybrid Solar Power Plant Reduces CO2 Emissions In Bali

The Nusa Penida Hybrid Solar Power Plant (PLTS), which began operating ahead of the G20 Summit in November 2022, until now continues to consistently supply clean energy for the PLN electricity system in Bali. This PLTS with a capacity of 3.5 Megawatts peak (MWp) is even able to reduce emissions of 4.19 thousand tons of CO2e per year for the island of Bali.

Being one of PLN’s showcases for initiating the energy transition, PLTS Nusa Penida is a commitment to PLN’s efforts to increase the new renewable energy (EBT) mix in the country. In addition to electricity, the PLTS which spans over 4.5 hectares of land is also a location for educational tourism in Bali.

Chairperson of the Center for Community Based Renewable Energy (CORE) at Udayana University, Ida Ayu Dwi Giriantari said that the presence of the Hybrid PLTS in Nusa Penida had a significant impact on reducing the use of fossil energy, especially during the day.

“This is a good example that should be improved, especially since Nusa Penida is a tourist destination, so it is mandatory to prioritize the use of clean energy, which has become the government’s commitment at both the central and regional levels,” said Ida.

This PLTS is a generator that operates with a hybrid system configuration consisting of a diesel power plant (PLTD), and PLTS and uses a Battery Energy Storage System (BESS) with a capacity of 1.84 megawatt-hours (MWh).

The General Manager of PLN’s Bali Distribution Main Unit, I Wayan Udayana, said that in order to accelerate the energy transition process, PLN will continue to add generating capacity based on renewable energy.

Udayana added that in 2023 there are planned to be additional EBT generators, namely PLTS in east and west Bali, each of 25 megawatts (MW) and Titab Mini-hydro Power Plant (PLTMH) with 1.3 MW power.

“This development plan will be carried out by PLN Indonesia Power which will later add to the mix of EBT generators to support the net zero emission target in 2060,” he added.

He also explained that PLN continues to collaborate with various parties including investors, government, communities and other parties. To realize the energy transition together, so that all Indonesian people can have access to reliable, affordable and clean electrical energy.
