Our verdict
Rushmore Energy, LLC sells electricity in US and takes contact by email and phone, so it suits households in Illinois, Maryland and Ohio who prefer writing or phoning a named supplier. The decision rests on the reference annual cost and exit fee in the comparison, against category unit rates that sit at €0.17.

Pros and cons
Pros
- Supply is listed as electricity, so the figure you compare is a single fuel quote rather than a pair to add up.
- The contract is with Rushmore Energy, LLC, a named company rather than a trading name.
- Support runs on email and phone, giving a written route and a spoken route at the same supplier.
- Coverage is set out state by state as IL, MD and OH, so eligibility can be checked before a quote is asked for.
- A US supplier in a category with a median unit rate of €0.17, which gives a clear benchmark for any price offered.
Cons
- Support runs on email and phone only, so a question that surfaces outside working hours has no live chat or help centre listed to take it.
- Supply covers electricity only (electricity), so a home with a gas supply still needs a second arrangement.
- Service is limited to Illinois, Maryland and Ohio, so a customer in any other state sits outside the listed coverage.
- Renewal is the pressure point: across this ranking the post contract median is €29.40 against an entry median of €23.03.
Who it suits
- Households in Illinois, Maryland and Ohio that need electricity only and like a written or spoken route, rather than the gas and electricity pairing at Powerpeers with electricity and gas.
- Buyers who read the terms before joining, since Rushmore Energy, LLC is named and the contract has a real entity to point at.
- People who are content to buy inside a listed service area and want support handled by email and phone.
Who should look elsewhere
- Anyone outside Illinois, Maryland and Ohio, who should start with a supplier that covers their own state.
- Homes that run gas as well as electricity, since electricity lists electricity alone where Endesa lists electricity and gas.
- Shoppers who prefer live chat or a self service help centre, because support runs on email and phone only.
Who runs it
Rushmore Energy trades as Rushmore Energy, LLC and is based in the United States, which answers the obvious questions before any price is read: there is a named company on the other side of the contract, and it works inside a single country market. The entity matters as much at renewal as at sign up, because a renewal, a credit or a complaint all need somewhere to land. Where a supplier trades only under a brand name, the company behind it can be harder to pin down, and here the name carried in the terms is the company itself. Contact runs on email and phone. That is short, and short cuts both ways. A household with a bill question and no wish to sit through a scripted phone queue can put the figures in an email, and anything urgent, such as a disputed meter reading or a move, can go down the phone instead. Set against that, no live chat window or self service help centre is listed, so a question that only appears outside working hours has nowhere else to go. Before committing to a term, the questions to put to that inbox or that phone line line up with the rows in the comparison: what the reference annual cost is for your own usage, what the unit rate and standing charge are at entry, what they become when the term rolls over, and whether leaving early carries an exit fee. Those answers carry more weight than a headline price, and a supplier that publishes a legal entity and a phone number gives you a party to ask.

Frequently asked questions
Which states does Rushmore Energy supply?+
Supply sits in the United States, and the areas served are listed as Illinois, Maryland and Ohio. That list is short enough to check against your own address in a moment, and it is the natural starting point, because a supplier outside your state cannot be quoted for your meter. If your state is missing from it, open the other suppliers on the comparison instead.
Who am I actually contracting with?+
The contract is with Rushmore Energy, LLC, and the company is based in the United States. A named legal entity is what you quote in a complaint, what stands behind the renewal price, and what you would search if a bill goes wrong. Trading under a brand alone leaves that harder to pin down, so read the entity in the terms before you sign anything.
Does Rushmore Energy sell gas as well as electricity?+
The fuels listed are electricity, so this is an electricity only supplier. A home that also runs a gas supply needs a second arrangement, or a supplier that lists both, such as Powerpeers with electricity and gas or Endesa with electricity and gas. Comparing a dual fuel plan against an electricity only one works, as long as both halves are added up on each side.
How do I get hold of Rushmore Energy?+
Support runs on email and phone. Email suits anything with numbers in it, such as a unit rate that does not match the bill or a standing charge you did not expect. A phone call suits anything urgent, like a disputed meter reading or a move. Both channels are listed for a customer base in the United States, and the legal entity behind them is Rushmore Energy, LLC.
What price figures should I compare before I join?+
Read the reference annual cost, the unit rate and the standing charge together, because a low unit rate can be offset by a heavy standing charge and the annual figure is what a bill reflects. Across the suppliers tracked in this category the median unit rate is €0.17 and the median starting price is €23.03, which gives you a benchmark to test against.
What happens to the price when the term ends?+
The pattern across suppliers in this ranking is that prices after a term sit above prices at entry, with a post contract median of €29.40 against an entry median of €23.03. Ask what you would be moved to at renewal and how much notice you get, because that question costs nothing now.
Is there an exit fee if I leave early?+
The exit fee sits in the comparison next to the reference annual cost, and it is worth reading on the row before you commit. Across the suppliers in this ranking the median exit fee is €0, so no charge is the common case, though the range reaches €131.54. If a move is plausible, weigh that figure first.
Can a single supplier cover gas and electricity instead?+
Yes, and all of the alternatives listed here cover both: Electricity Ratings with electricity and gas, Powerpeers with electricity and gas, and Endesa with electricity and gas. Rushmore Energy lists electricity, so a dual fuel household is weighing a single fuel plan against a pair. Add the missing fuel to both sides before deciding.
