Bali has no public charging network for electric yachts. Boats charge at their home berth from marina shore power, usually 220V/50Hz single phase in the 16–63A range, topped up by solar during the day and by a small generator on long runs. For guests this means one thing: an electric rental day is planned around the state of charge the boat left with, so the cruising radius is agreed the night before, not on the pier.
The honest picture: charging happens at base
Renters often imagine an electric boat pulling into a cove and plugging in somewhere. That infrastructure does not exist in Indonesian waters, and it will not for years. Every electric or hybrid vessel working out of Bali charges where it sleeps — on a marina pontoon in the Benoa harbour area, at a private mooring with a shore cable, or at an operator’s own yard. The charge that matters to your day was put into the batteries overnight, before you woke up.
That is not a limitation so much as a planning fact. A diesel boat can refuel almost anywhere fuel is trucked; an electric boat carries its whole day in a battery bank. So the conversation with the operator moves earlier: instead of asking how far the boat can go, you ask what the boat will leave the dock with and what that buys in hours at cruising speed.
What the dock actually supplies
Indonesian shore power is 220V at 50Hz. Marina pedestals in Bali commonly offer 16A and 32A single-phase outlets, with 63A available on some commercial berths. Larger yards and commercial piers sometimes carry three-phase supply, which is what makes an overnight full charge realistic on a bigger battery bank rather than a two-day affair.
| Supply | Rough continuous draw | Practical use |
|---|---|---|
| 16A single phase | ~3.5 kW | Trickle charge, hotel loads, small tenders |
| 32A single phase | ~7 kW | Overnight charge on a mid-size hybrid bank |
| 63A single phase | ~13 kW | Same-day turnaround between two rental slots |
| Three phase (commercial berth) | 20 kW and up | Full charge on a large catamaran bank overnight |
Figures are indicative and vary by berth, cable and the vessel’s own charger rating — a boat with a 7 kW onboard charger cannot absorb more than 7 kW no matter how generous the pedestal is. If the state of charge matters to your itinerary, ask which pedestal the vessel uses and what the onboard charger is rated at. Any operator running electric seriously will know both numbers.
Solar is the second plug
The panels on a modern electric catamaran are not decoration. A hard-top array on a 45–50ft catamaran commonly runs somewhere between 2 and 6 kWp, and in Bali’s light a well-oriented array will return several usable kilowatt-hours across a clear day. That does not propel the boat by itself at speed, but it is often enough to carry the hotel load — fridges, water maker, lights, fans, entertainment — which is the load that quietly drains a bank while you are anchored for lunch.
Two things move solar yield in practice: cloud and shading. October to March brings more cloud, and an awning or a badly furled sail across the array costs more output than most guests would guess. Crews on electric boats spend real attention on this, which is why the array is usually kept clear even when it would be convenient to hang something over it.
The generator question
Most electric vessels working commercially in Indonesia are hybrids rather than pure battery boats. There is a compact diesel generator aboard, sized to charge the bank rather than to drive the propellers. It exists for the day the plan changes: a longer crossing, an unexpected current, a guest who wants two more hours at Nusa Penida.
Ask how the operator uses it, because the answer tells you what kind of day you are buying. Some run the generator only as a reserve and will shorten the route rather than start it. Others treat it as normal range extension. Neither is wrong; they are different products. If silence is the reason you booked, say so at enquiry, and read our note on silent electric charters in Bali before you choose the vessel.
What charging means for your rental day
- Departure time is real. A late start eats the charge window if the boat is on a same-day turnaround between a morning and a sunset slot.
- Range is agreed, not improvised. Route changes on the water are possible but they are a battery decision, not just a navigation one.
- Speed is the biggest lever. Energy use climbs steeply with speed; dropping two knots can add a surprising amount of cruising time.
- Anchoring is free. Time at anchor costs almost nothing on an electric boat, which is why these vessels suit long, slow days in one or two bays rather than sprint itineraries.
How this changes the boats you should shortlist
If your plan is a full-day run to the Nusa islands with three stops and a fixed return time, a conventional motor yacht is the more honest tool, and our motor yacht rental notes set out the speed and range trade-off. If your plan is a long lunch in a quiet bay with swimming, paddleboards and no engine drone, the electric fleet is genuinely better at that job, not merely greener.
Rates reflect the difference. Electric and luxury catamarans in Bali sit around USD 2,500–5,500 for a full day and USD 1,400–2,900 for a sunset or half-day slot, against USD 1,800–4,500 for a comparable 45–60ft motor yacht — the full picture is on our electric yacht pricing page and the wider Bali day rate bands.
Questions worth asking before you book electric
- What state of charge will the boat leave the dock with on my date?
- What is the cruising range at the speed you actually plan to run?
- Is there a generator, and under what circumstances will the crew start it?
- Is my slot a same-day turnaround from an earlier booking?
- What happens to the route if the day is heavily overcast?

Frequently Asked Questions
Can I charge an electric yacht anywhere in Bali?
No. There is no public charging network for yachts in Indonesia. Vessels charge at their home berth from marina shore power, supported by onboard solar and, on hybrids, a small generator.
How long does a full charge take?
It depends on the pedestal and the vessel’s onboard charger. A 32A single-phase supply feeding a roughly 7 kW charger will typically cover an overnight charge on a mid-size bank; larger banks need a commercial three-phase berth to finish overnight.
Does solar really contribute anything useful?
Yes, mainly by carrying hotel loads. A hard-top array on a 45-50ft catamaran commonly runs 2-6 kWp and in Bali light will cover fridges, water maker and lighting through a clear day, leaving more of the bank for propulsion.
Will the crew start the generator during my day?
That is an operator policy question worth asking at enquiry. Some run the generator only as reserve and will shorten the route instead; others treat it as normal range extension. If silence is why you booked, state that when you enquire.
