Indonesia
What an Indonesian household should know before buying a home battery: why net metering ended, how the PLN rooftop quota works, what that means for storage, blackout risk and portable power stations.

- Legal and press sources
- Checked 13 November 2026
- MEMR Regulation No. 2 of 2024 abolished net metering for rooftop solar and replaced it with a quota system. Households can no longer offset exports against imports the way they could under MEMR Regulation No. 26 of 2021.
- PLN sets rooftop solar quotas: 485 MW opened for January 2026, and PLN was reported to be seeking about about 1,400 MW for the full year. Quota decides whether you can connect, so ask before you buy.
- Without net metering, the value of rooftop solar lies in self-consumption. A press report notes that on-grid users used to avoid a battery because exports offset their costs. Now a battery is the way to use daytime power in the evening.
- Blackouts and outer-island diesel costs are a strong second reason: IEEFA argues that rooftop solar plus a battery gives households resilience.
- We could not confirm whether any exports are paid after the rule change, nor any subsidy, VAT or import duty relief for household batteries.

How the Indonesian market works
PLN is the state electricity company. Households are its largest customer group: 42% of the 318 TWh PLN sold in 2025, according to IEEFA, in a country of about 287.2 million people (IEEFA). Rooftop solar for households is regulated by the Ministry of Energy and Mineral Resources (MEMR) and connected through PLN.
Indonesia is an archipelago, so grid quality varies widely between Java and the outer islands, and so does the cost of diesel. That affects the case for a battery.
Net metering ended in 2024
In early 2024 MEMR enacted MEMR Regulation No. 2 of 2024, which abolishes net metering for rooftop solar (pv magazine). Net metering had allowed owners to export surplus power to PLN and offset it against their evening use. A law firm summarises that the new rule removes the net metering scheme but also removes the capacity charge that commercial customers had to pay (SSEK).
A news report quotes users who say that, with the export stipulation gone and a quota in place, rooftop solar is less attractive, because residential customers use a large part of their electricity in the evening (Asia News Network).
We could not confirm whether any exported energy is paid for after the change, or at what rate. Ask your PLN office in writing, and design the system for self-consumption.
The PLN rooftop quota
Under MEMR Regulation No. 2 of 2024, the installed rooftop capacity PLN will allow is set by quota (Baker McKenzie). A trade report says the programme sets quotas to 5.7 GW by 2028 (Reccessary).
The quota for January 2026 opened at 485 MW (pv magazine). The Jakarta Post reported in January 2026 that PLN was being asked to raise the 2026 total by 400 MW to about about 1,400 MW (Jakarta Post). We could not read the full articles, so the figures are as reported.
Before you order a system, ask the installer to confirm that quota is available for your PLN area and that the application is filed.

Why batteries matter now
Before the change, on-grid owners did not need to invest in costly battery storage because they could offset costs by selling electricity to PLN (The Star). That reasoning is now reversed: if the grid no longer credits your exports, storing midday power for the evening is the main way to use it.
IEEFA recommends reinstating meaningful net metering, revising quota rules and supporting the ESCO model, and says rooftop solar plus a battery gives households resilience against fuel supply shocks and local outages (IEEFA).
Size the battery to your evening load, not your daytime load. An air-conditioned home with a large night load needs more storage than a home that uses power mostly in the day.
Heat, humidity and safety
Heat and humidity shorten battery life. Choose lithium iron phosphate (LFP), install the battery in a shaded, ventilated place away from direct sun and standing water, and check the manufacturer's operating temperature range. Flooding is a risk in many areas, so mount equipment above expected water levels.
A grid-tied inverter normally shuts down in an outage. For backup, ask for a hybrid or backup-capable inverter, with a backup circuit wired by a qualified electrician. We found no Indonesian rule specific to household battery installation, so follow the manufacturer's instructions and ask PLN what it requires.
Tax, duty and incentives
We could not confirm VAT treatment, import duty, local-content rules for households or any subsidy for household batteries. Local-content (TKDN) rules apply to some government-linked projects, but we found nothing that says how they affect a private household purchase. Ask your installer to show VAT on the quote and ask an accountant before you rely on any relief.
Portable power stations versus a home battery
Interest in portable power stations in Indonesia is higher than in home batteries. A power station is a battery with sockets that you can use immediately for phones, lights, a router, a fan or a laptop. It is not wired into the house and does not feed power into the grid.
A home battery is installed by an electrician, can run whole circuits and works with rooftop solar. Choose a power station for portable backup of a few devices, and a home battery to move solar power into the evening and keep a house running.
Outside Indonesia
Rules, tariffs and incentives for home batteries differ from country to country, so do not apply the figures on this page to a home elsewhere. We are adding guides for other countries to this section.
Common questions about Indonesia
Does Indonesia still have net metering for rooftop solar?
No. MEMR Regulation No. 2 of 2024 abolished net metering for rooftop solar installations.
Do I need permission from PLN to install rooftop solar?
Yes. Grid-connected rooftop systems are connected through PLN, and capacity is allocated by quota. Ask your installer to confirm that quota is available and the application is filed.
Is a home battery worth it in Indonesia?
Without net metering, using your own solar in the evening is the main way to benefit, which is what a battery enables. Whether it pays depends on your evening use, tariff and quote.
Are exports paid after the rule change?
We could not confirm whether any exports are paid, or at what rate. Ask PLN in writing.
Is there a subsidy or tax relief for a home battery in Indonesia?
We could not confirm any. Ask your installer and an accountant.
Is a portable power station the same as a home battery?
No. A power station plugs into individual devices and is not wired into the house. A home battery is installed by an electrician and can run whole circuits and work with solar.
