Indonesia's utility landscape has a few features that catch newcomers off guard — most notably PLN's prepaid electricity token system, tap water you should never drink, and home internet that you absolutely must verify before signing a lease. None of it is hard once you know how it works.
Indonesia's electricity is supplied by PLN (Perusahaan Listrik Negara), the state-owned monopoly. The rate is reasonable. The system is functional. But two things will catch you off guard if you're coming from Thailand or Malaysia: the prepaid token system, and power outages that are more frequent than you're used to.
PT PLN Persero is Indonesia's sole electricity provider, serving the entire archipelago from Java to remote eastern islands. Grid reliability varies enormously by location — Bali and Jakarta have reliable modern infrastructure with infrequent outages in established areas. Lombok, Flores, and more remote islands experience significantly more disruptions, and in outer provinces the grid can be genuinely unreliable during peak periods or bad weather.
The standard non-subsidized residential rate for connections of 1,300 VA and above — which covers most expat villas and apartments — is approximately IDR 1,444.70/kWh (~$0.09 USD). This rate has been relatively stable since 2022 and is adjusted quarterly based on macroeconomic factors. Indonesia's rate sits slightly above Vietnam's but below Thailand's on a USD basis.
This is the thing most newcomers don't know about: the majority of Indonesian residential properties — particularly villas and houses in Bali — use a prepaid electricity system called prabayar. Instead of receiving a monthly bill, you purchase electricity tokens in advance. A 20-digit code is entered into the smart meter, and the corresponding kWh amount is credited to your balance. When the balance runs low, the meter beeps. When it hits zero, the power cuts.
Tokens are purchased at any Alfamart or Indomaret convenience store (ubiquitous), via the PLN Mobile app, through GoPay/OVO/Dana, or at bank ATMs. You can buy in amounts from IDR 20,000 upward — though for practical purposes, most expats top up IDR 200,000–500,000 at a time. The system is actually convenient once you're used to it; the only danger is forgetting to check your balance and running out at an inconvenient moment.
| Connection Category | Rate (IDR/kWh) | USD/kWh | Typical Property |
|---|---|---|---|
| R-1 / 900 VA (subsidized) | IDR 1,352 | ~$0.085 | Small local homes (subsidized category) |
| R-1 / 1,300 VA – R-2 / 5,500 VA | IDR 1,444.70 | ~$0.091 | Standard expat villa or apartment |
| R-3 / 6,600 VA and above | IDR 1,699.53 | ~$0.107 | Large villas, commercial properties |
Indonesia has exceptional solar potential — Bali and Java receive abundant sunshine year-round and solar adoption among villa owners has grown significantly. PLN operates a net metering program (PLTS Atap — rooftop solar) allowing homeowners to export surplus generation back to the grid at a credited rate. The program requires PLN approval and registration, which adds paperwork but is increasingly common among Bali property owners.
A 3–5 kWp system costs approximately IDR 30–60 million installed (~$1,900–$3,800 USD) — cheaper than Thailand and Malaysia due to lower local labor costs. For villa owners or long-term leaseholders in Bali, the combination of high sunshine hours, relatively high IDR electricity costs (compared to Vietnam), and frequent enough outages to motivate backup power makes solar with battery storage an increasingly attractive investment. Ask any reputable Bali-based solar installer for a site-specific payback analysis.
Unlike Malaysia and urban Thailand where outages are rare, power interruptions are part of life in Indonesia outside major city centers. In Bali's tourist zones, grid reliability has improved with infrastructure investment driven by tourism demands — but outages still occur during storms and at peak times. Remote areas of Lombok, Flores, and island destinations can experience outages lasting hours.
Long-term expats and villa owners in Indonesia routinely install backup infrastructure: a small generator (IDR 5–15 million for a quality unit) for extended outages, or an inverter/battery system that handles short cuts automatically. For remote workers whose income depends on connectivity, an uninterruptible power supply (UPS — IDR 1–5 million) for computers and networking equipment is essential. Budget this as part of your setup cost, not as an optional extra.
Indonesia's tap water is not safe to drink anywhere in the country — not in Bali, not in Jakarta, not in any major city. This is non-negotiable and applies universally. The practical solutions are simple and well-established; they just need to be set up from day one.
Water supply in Indonesia varies more dramatically than in any other country in this guide. In established urban areas of Jakarta and parts of Bali (particularly in developed villa zones), municipal piped water from PDAM (Perusahaan Daerah Air Minum — local government water companies) is available. Outside these areas, properties commonly rely on private wells, water tanker delivery, or rainwater collection.
Many Bali villas — particularly those away from central Seminyak and Canggu — do not have PDAM connection at all. Water is delivered by tanker truck to a property storage tank, which then supplies the taps. This is a normal and functional system but means your water supply depends on tank capacity, delivery schedules, and the dry-season availability of the tanker service. Ask specifically about water source and tank capacity before committing to any rental.
Whether your water comes from PDAM pipes, a private well, or a tanker truck, it is not safe to drink directly. PDAM water may be treated at source but distribution infrastructure is inconsistent. Well water contamination — from septic systems, agricultural chemicals, and in coastal Bali from saltwater intrusion — is well-documented. Tanker water quality depends entirely on the supplier's standards, which are unregulated.
The result: every expat and local who cares about their health in Indonesia filters or buys their drinking water. No exceptions. This isn't paranoia — it's the universal standard practice across the entire archipelago.
Expats staying in Indonesia for a year or more — particularly those in villas rather than serviced apartments — typically invest in a multi-stage filtration system. Given that Indonesian tap/well/tanker water quality is lower than in Thailand or Vietnam, a full reverse osmosis system with UV sterilization is recommended rather than a basic sediment filter alone.
A quality whole-house or under-sink RO+UV system costs IDR 3–10 million installed (~$190–$630 USD). This eliminates the ongoing galon delivery cost, provides cooking and brushing water directly from the tap, and significantly reduces the daily logistical overhead of water management. Filter replacement costs IDR 500,000–2,000,000 per year. For anyone in a fixed property for more than 12 months, the investment pays for itself quickly and dramatically improves quality of life.
Many Bali villas and rural Indonesian properties rely on private wells as their primary water source. Bali's well water quality varies significantly by area — in densely built areas of south Bali where septic systems are numerous and close together, groundwater contamination is a real risk. Saltwater intrusion affects coastal areas. Agricultural chemical contamination affects farming regions.
Rainwater harvesting is viable in Indonesia's wet climate — a 6-month rainy season provides abundant collection opportunity. For properties with sufficient roof area and storage tank capacity, harvested rainwater combined with a good filtration system provides a reliable supply independent of delivery services. Long-term expats in rural Bali and Java often operate hybrid systems — well for household use, rainwater for garden irrigation, filtered water for drinking. This is a practical and sustainable approach that many experienced Indonesia-based expats end up on.
Internet availability in Indonesia is the utility that most commonly blindsides newcomers — particularly in Bali. Fiber is available in many areas, but which providers serve which streets, buildings, and villas is highly variable. Confirming your internet situation before committing to a rental is not optional.
Indonesia's mobile market is competitive with several strong operators. The coverage gap between Telkomsel and the others is the most significant in Southeast Asia — if you travel beyond tourist zones, it matters significantly which SIM you carry.
Telkomsel is Indonesia's largest and most reliable mobile operator by a meaningful margin. Its 4G and expanding 5G network covers virtually all of Java, Bali, and extends further into remote areas than any competitor. For expats who travel around the archipelago — or who simply want the most reliable connection in Bali's more remote areas — Telkomsel is the answer. It's slightly more expensive but the coverage difference is real.
Indosat Ooredoo Hutchison (the result of a major 2022 merger) offers competitive pricing and large data quotas — favored by heavy data users and those staying primarily in urban areas. XL Axiata is popular among digital nomads in Bali's major hubs (Canggu, Seminyak, Uluwatu) where coverage is strong. Smartfren is the budget option with more limited coverage — useful as a secondary SIM.
SIM cards are available at Ngurah Rai Airport (Bali) and Soekarno-Hatta (Jakarta) immediately on arrival, at official operator stores, at Alfamart and Indomaret convenience stores, and at phone shops in every shopping center. Passport registration is required — a legal requirement since 2018. Never buy SIMs from unofficial street vendors — the risk of receiving an already-registered or problematic SIM is real.
Tourist SIMs are available with 15–30GB of data from IDR 50,000–150,000. For longer stays, standard monthly data plans range from IDR 80,000–300,000/month depending on data allowance. eSIM is available from Telkomsel and can be activated digitally before arrival — useful for immediate connectivity on landing. Dual-SIM phones with both a home eSIM and a local Indonesian SIM is the setup most digital nomads in Bali use.
| Plan Type | Provider | Cost | Data | Best For |
|---|---|---|---|---|
| Tourist / Short Stay | Telkomsel / XL | IDR 50,000–150,000 | 15–30GB high speed | Visits under 30 days |
| Monthly Data Pack | Indosat / XL | IDR 80,000–200,000/mo | 30–100GB | Budget-conscious medium stays |
| Monthly Unlimited | Telkomsel / Indosat | IDR 150,000–300,000/mo | Unlimited (fair use daily cap) | Remote workers, long stays |
| eSIM (Tourist) | Telkomsel | IDR 100,000–200,000 | 10–25GB | Activate before arrival, no SIM swap |
The major streaming platforms all operate in Indonesia, and on Bali's decent fiber connections they work well. The local streaming ecosystem is also the most developed in this guide outside Malaysia — Indonesia has its own strong digital entertainment market.
Netflix, Disney+, HBO Max, Amazon Prime Video, and Apple TV+ all operate in Indonesia with local-market content libraries. Netflix's Indonesian original content has become significant — several Indonesian series have become internationally recognized. YouTube is unrestricted and widely used. Spotify works normally.
Local streaming services are genuinely strong: Vidio (owned by Emtek) offers Indonesian TV channels, sports (including Premier League rights in Indonesia), films, and local originals — monthly plans from around IDR 35,000–70,000/month. GoPlay (Gojek's streaming service) and iQIYI (popular for Asian drama content) are also widely used. For expats who want live Indonesian TV or sports coverage, Vidio is the primary local option.
VPN use is common and generally tolerated in Indonesia for personal use. Indonesia blocks gambling sites, pornography, and some political content — but does not implement anything approaching China-level censorship. The vast majority of Western services and social media platforms work without restriction. WhatsApp, Instagram, Facebook, Twitter/X, and Google services all function normally.
VPNs are primarily used by expats for accessing home-country streaming libraries — the Indonesian Netflix library differs from US/UK/Australian libraries. ExpressVPN, NordVPN, and Surfshark all work reliably on Indonesian internet connections. Note that connection quality through VPN will only be as good as your underlying internet — on a shared villa WiFi with limited bandwidth, VPN streaming may be unreliable regardless of VPN quality.
Traditional satellite TV (MNC Vision, K-Vision) provides Indonesian channels and some international options for those who want it. More practically for expats, IndiHome's fiber subscription includes a TV package (IndiHome TV) at no significant extra cost — accessible on a set-top box with Indonesian channels and some international news (CNN Indonesia, BBC World). For most expats, this functions as background noise TV rather than a primary entertainment source, with streaming platforms handling actual content consumption. Dedicated international sports coverage in English (Premier League, F1) typically requires either Vidio's premium subscription or a VPN to access a home-country streaming sports service.
Indonesia's utility costs are low in absolute terms — but higher than Vietnam and with more setup complexity. The dual columns show the difference between a Bali tourist-zone villa and more local living situations outside the inflated expat corridor.
