Know exactly what you're paying for electricity — and why. CurrentCost shows your local electricity rate, how it's changed over the past year, and what it's costing you to power your home right now. Live grid data — See real-time wholesale electricity prices from your ISO/RTO — ISO-NE, NYISO, MISO, SPP, CAISO, ERCOT, and PJM. Understand the difference between what utilities pay for power and what shows up on your bill. Energy resource mix — See exactly what's generating your electricity right now — natural gas, nuclear, wind, solar, hydro. Watch the mix shift hour by hour as solar peaks at noon and gas ramps up in the evening. Appliance cost calculator — Find out what it actually costs to run your air conditioner, electric dryer, or EV charger. Enter your wattage and hours — get daily, monthly, and annual cost estimates. EV charging optimizer — Compare the cost per mile of driving electric vs. gas. See time-of-use rate schedules for your region and find the cheapest, cleanest window to charge overnight. Data center explorer — Map data centers across the U.S. — both online and planned. See who operates each one and how much power it draws, and get a clearer picture of where major new electricity demand is taking shape. Rate trend — Track how your state's residential electricity rate has changed over the past 12 months and how it compares to the national average.
