How Much Does Con Edison Charge Per kWh?
The short answer: Westchester County residential customers on Con Edison pay between $0.33 and $0.38 per kWh as a blended rate. But that number is misleading if you only look at the supply charge on your bill, which shows approximately $0.178 per kWh. The real cost is much higher because Con Edison bills include both supply and delivery charges, plus surcharges, taxes, and system benefit charges that add up significantly. When you divide your total electricity charges by your total kWh used, the effective rate for most Westchester homeowners lands in the $0.33 to $0.38 range. If you are unsure what you are paying, our Con Edison bill guide walks through exactly where to find your effective rate.
Con Edison Supply Charge vs Delivery Charge
Your Con Edison bill has two main components. The supply charge covers the cost of the electricity itself, purchased on the wholesale market through NYISO. As of 2026, the standard residential supply rate (PTC) is approximately $0.178 per kWh. This rate fluctuates seasonally based on weather, demand, and wholesale energy prices. Summer months are typically higher. The delivery charge covers the cost of moving that electricity from power plants to your home through Con Edison infrastructure. Delivery includes transmission, distribution, system benefit charges, and various surcharges. Delivery charges are often equal to or greater than supply charges, which is why the total blended rate is roughly double the supply rate alone.
Why Are Con Edison Rates So High?
Westchester County has some of the highest residential electricity rates in the country. Several factors drive this. Con Edison is investing heavily in grid infrastructure to handle increased demand from EV adoption, electrification mandates, and growing data center construction across the region. These capital investments get recovered through delivery rate increases approved by the New York Public Service Commission. For 2026, Con Edison received approval for a 2.8% delivery rate increase, and Westchester residential customers using 425 kWh per month will see their bills increase by approximately $5.32 (a 3.6% total increase). The rate trajectory has been consistently upward, with no signs of reversing.
Con Edison Rates: Flat Rate vs Time-of-Use
Most Westchester homeowners are on the EL1 flat rate, which charges the same blended rate regardless of when you use electricity. The alternative is TOU Rate III (time-of-use pricing), which splits your rate by time of day. On TOU Rate III, off-peak hours (midnight to 8 AM weekdays, all weekend) cost approximately $0.05 per kWh. Peak hours (8 AM to midnight weekdays) cost approximately $0.38 per kWh. That is a 7.6x spread. For homeowners with battery storage or the ability to shift usage to off-peak hours, TOU Rate III can reduce the effective rate by 25 to 40 percent compared to the flat EL1 rate.

NYSEG Rates Per kWh in Westchester
NYSEG serves northern Westchester towns including Yorktown, Cortlandt, Peekskill, and parts of Putnam County. NYSEG residential rates are lower than Con Edison, averaging approximately $0.23 per kWh blended. The gap between Con Edison and NYSEG pricing is significant. A household using 10,000 kWh per year pays roughly $1,000 to $1,500 more per year on Con Edison than the same household would pay on NYSEG. This rate gap makes solar economics stronger in Con Edison territory because the savings per kWh offset are higher.
How Westchester Homeowners Are Lowering Their Rate
The homeowners paying the least per kWh in Westchester right now are using a combination of three strategies. First, solar panels to generate their own electricity and reduce grid purchases. Second, battery storage to store cheap off-peak electricity and discharge during expensive peak hours. Third, TOU Rate III to maximize the value of that battery arbitrage. This combination can drop the effective cost per kWh from $0.35+ down to $0.10 to $0.15, depending on system size and usage pattern. NYSERDA incentives reduce the upfront cost of both solar and battery systems, and the NY State 25% tax credit (up to $5,000) applies to the full installation cost.
What Will Con Edison Rates Be in 2027?
Based on approved and filed rate cases with the NY Public Service Commission, Con Edison delivery rates will continue increasing through 2027 and 2028. The PSC has a multi-year rate plan framework that locks in annual adjustments. Supply charges are harder to predict because they depend on wholesale energy markets, natural gas prices, and weather patterns. However, the long-term trend is clear: residential customers in Westchester have seen a roughly 6% compound annual growth rate in blended electricity costs from 2023 to 2026. At that trajectory, a homeowner paying $0.35 per kWh today would be paying approximately $0.42 per kWh by 2028. Every dollar of rate increase makes solar and battery storage more valuable because it widens the gap between grid cost and self-generated cost.
