So far, the main challenges in implementing renewable energy have been related to operation and maintenance, which is crucial for the sustainability of solar power plants built and implemented within the community.

Following the revitalisation of the Refurbishment of 75 kWp Solar Microgrid on Pulau Tiga, PLN Maluku and North Maluku (MMU), along with NZMATES and the Asian Development Bank (ADB), conducted a site visit on Friday, 17 May 2024, as part of the 2023 Annual Verification Mission Result Based Load (RBL) for ADB Kalimantan, Maluku, and Papua (KMP).

New Zealand Maluku Access to Renewable Energy Support (NZMATES) conducted a training session on the operation and maintenance of Solar Power Systems (PLTS) from 4-6 June 2024, following a similar session previously held in Buru District 4-6 December 2023.

Since May 1st, 2024, 56 households served by PLN in Pulau Tiga have enjoyed 24-hour access to electricity from renewable energy sources, thanks to a refurbishment project executed in collaboration between New Zealand and Indonesia.
