What is Unlimited Energy?
It might be easier to start with what Unlimited Energy is NOT. Our Unlimited Energy Plan is not surprising. It’s not stressful. And it’s not hard to understand.
We’ll help you easily switch to Unlimited Energy, with no interruption to your service and, for the length of your contract, the supply portion of your bill will never change. Cold winter? Turn up the heat. Hot Summer? Crank the air. And you still won’t be surprised by your supply charge.
Why Choose Unlimited Energy?
Even if you’re the kind of person who loves surprises, there are some things you want know in advance — like how much you’ll owe for your electricity or natural gas supply, no matter how much you use.**

Energy Supply Charge Explained
Energy Supply charges refer to the cost of the actual electricity or natural gas itself — this is the rate you can lock in to access a supply of energy. With other plans, you may pay a different amount depending on the time of the year and the amount of energy you use…but with Unlimited Energy, this portion of your bill never changes.
Your Unlimited Energy rate does not include charges from your utility related to delivery or other fees, and state and local taxes.
Using Your Energy For Good
We all want peace of mind, knowing our needs will be met every month – stable, predictable, and stress-free. And we want to help provide that peace of mind in other ways, too. This is why we team with hunger–relief charities to help provide the security of healthy meals to those in need. With every Unlimited Plan, we’ll contribute to this cause, and you’ll be a force of good in the world simply by powering your home.***
