Run the numbers
on your energy bill.

Three free tools, all in one place. Each one uses only the numbers you type in and prices that are published and sourced. None of them is a quote, and none needs your email.

In PJM states, capacity prices have risen sharply. Enter your peak load contribution (PLC) to estimate your yearly capacity charge.

03

Load Factor Check

How evenly do you use power? A low load factor means short, sharp peaks, and demand and capacity charges take a bigger share of your bill.

Rate vs. Price to Compare

Is your rate above or below your utility's default price?

Your utility sets a default supply price. If you shop for a supplier, your rate can land above or below it. Pick your utility, then enter the supply rate from your bill and your monthly usage.

Use the supply (generation) rate in cents per kWh, not your total bill. It is on your bill or in your supplier contract.

This compares supply prices only. Your total bill also includes delivery charges, taxes, and fees, which this tool leaves out. Default prices change, so check the date shown. It is an estimate for comparison, not a quote or a guarantee of savings. See every utility's official price.
