Con Edison Electric Rates Per kWh Calculator
This calculator helps you estimate your Con Edison electricity costs based on your usage and the current tiered rate structure. Understanding your electricity rates is crucial for managing your energy bills. Con Edison, like many utility providers, uses a tiered rate system, meaning the price you pay per kilowatt-hour (kWh) can change depending on how much electricity you consume within a billing period.
There are several rate classes, but for residential customers, the primary structure often involves different prices for different tiers of usage. Higher usage typically incurs a higher per-kWh rate. This calculator simplifies this by allowing you to input your estimated monthly kWh usage and see the potential cost based on the current Con Edison residential rates.
