Pros and cons
Pros
- Exit fees come to $0, and the brand places 1 of 29 suppliers ranked on exit fees.
- Renewable supply rests on own generation, so the green claim is tied to generation the supplier owns rather than certificates it buys.
- Support covers email, phone and help centre, so a call, an email and a help centre are all available.
- The tariff line-up is deliberately short, green, which keeps the decision simple for a new entrant to green supply.
- A customer base of 65,000 and a trading history back to 2006 point to a provider with staying power.
Cons
- Coverage stops at CO, MD and DE, so households elsewhere in US cannot join.
- Electricity is the only fuel, electricity, so gas has to come from another supplier.
- Tariffs are limited to green, where Endesa offers fixed, time of use and ev and 100Green offers fixed, variable and green.
- Support runs on email, phone and help centre only, so anyone who prefers live chat has fewer ways to get an answer.
Who it suits
- Households in Colombia, MD and DE that want green electricity and an exit fee of $0.
- Readers who want a green-only tariff, green, rather than the mixed rate structures at 100Green, fixed, variable and green.
- Customers who want a phone line and a help centre, email, phone and help centre, from a supplier trading since 2006.
Who should look elsewhere
- Anyone outside CO, MD and DE, because the plan does not reach their state.
- Households after a fixed, variable or time-of-use structure, which Octopus Energy covers under fixed, variable and green and Endesa under fixed, time of use and ev.
- Dual-fuel households, since electricity is the only fuel on offer.
Who runs it
The legal entity behind the plan is Nautilus Solar Energy, LLC, headquartered in the United States. It has been trading since 2006, which places it among the longer established names in renewable supply. Support comes through email, phone and help centre, so you can call, write or work through the online help centre, and a call is the quickest route for anything urgent about your account.

Frequently asked questions
Does Nautilus Solar charge an exit fee?+
The listed exit fee is $0, so there is nothing to pay to leave once the plan is running. That places the brand at 1 of 29 suppliers ranked on exit fees, which matters if you expect to move home or change supplier part way through.
Which states can I sign up in?+
Service runs in Colombia, MD and DE, and the supplier's market is US. An address outside those states falls outside the service area, so it is worth checking your own post code before switching. Coverage is narrow rather than nationwide.
Does Nautilus Solar supply gas as well as electricity?+
Electricity is the only fuel, electricity. There is no gas product, so a household already on a dual-fuel contract would need a second supplier for that side. The green tariff, green, covers electricity alone.
What kinds of tariff are on offer?+
The range is narrow. Nautilus Solar lists green as its tariff type, where Endesa lists fixed, time of use and ev and 100Green lists fixed, variable and green. Fixed, variable and time-of-use structures are not part of the offer, which suits readers who want a straightforward product rather than a long rate sheet.
Where does the green electricity come from?+
The renewable basis is own generation, so the power is generated by the supplier rather than bought from a wholesale market and resold under a green label. That is a different starting point from suppliers who rely on certificates, and it is the reason the tariff line is described as green.
How do I get help from support?+
Support runs on email, phone and help centre. Email and phone are both offered, and there is a help centre for written questions. Live chat is not among the listed routes, so anyone who prefers instant messaging would need to use one of the channels above instead.
Who owns the company behind the plan?+
The supplier is Nautilus Solar Energy, LLC, based in the United States. It has been trading since 2006 and serves 65,000 customers. The company sells a green tariff, green, rather than a broad set of fixed and variable products.
How large is the customer base?+
The stated base is 65,000 customers, and the market served is US. The plan reaches CO, MD and DE, so those customers sit inside a limited set of states rather than across the whole country. Anyone outside those states should look at suppliers with wider coverage.
