Looking to restart my blogging effort as utility rates are constantly rising.
If you’ve ever wondered why your power bill seems to change even when your usage doesn’t, you’re not alone. One of the biggest factors is the delivery rate—the cost your utility charges to bring electricity to your home. If your bill feels higher in 2025, it’s not just your imagination—delivery rates are up about 33% compared to early 2023. I’ve tracked my own rates over the past few years, and here’s what I found when comparing 2023 and 2025.
Delivery Rate Trends: 2023 vs. 2025
2023: A Year of Sharp Increases
- Started at: 13.91¢/kWh (January)
- Ended at: 17.55¢/kWh (December)
- Peak: 17.55¢/kWh (September)
- Total increase: +4.44¢ (+33.8%)
2025: Higher, But More Stable
- Started at: 17.89¢/kWh (January)
- Ended at: 18.81¢/kWh (October)
- Peak: 20.06¢/kWh (July)
- Total increase: +0.92¢ (+5.1%)
What Does This Mean for Your Bill?
If your bill feels higher in 2025, it’s not just your imagination—delivery rates are up about 33% compared to early 2023.
2023 saw a steep climb in delivery rates, especially in the second half of the year.
2025 rates started higher but increased more gradually.
Electric Supply Rate Comparisons: 2023 vs 2025
How My Electric Supply Rates Changed: 2023 vs. 2025
When reviewing my power bills, I always pay close attention to the electric supply rate—the price I pay for the actual electricity I use, before any delivery or service charges are added. In 2023, I was enrolled in the Sustainable Westchester flat rate plan. In 2024, I switched to a variable rate plan using Constellation Energy as my supplier. Here’s what I discovered when comparing my supply rates in 2023 and 2025.
What Is the Electric Supply Rate?
The electric supply rate (cents per kWh) is the cost of the electricity itself, set by your utility or energy supplier. This rate can change based on market conditions, contracts, and regulatory decisions.
Supply Rate Trends: 2023 vs. 2025
2023: Stable Supply Rates
- Start: 0.157¢/kWh (January)
- End: 0.157¢/kWh (December)
- Change: 0.00¢ (0.00%)
- The supply rate remained completely flat throughout the year.
2025: Noticeable Increase, But Still Below 2023 Flat Rate
- Start: 0.108¢/kWh (January)
- End: 0.135¢/kWh (October)
- Change: +0.027¢ (+25.5% increase)
- The supply rate started lower than in 2023 and climbed steadily through the year. Even with variable rates in 2025, the peak rate has not surpassed the 2023 Sustainable Westchester flat rate—it’s still about 13% lower than the 2023 flat rate.
Comparing Sustainable Westchester Flat Rates to Variable Constellation Sustainable Rates
If you’re considering which supply rate plan is best for you, it’s helpful to compare the current options available in Westchester County.
Sustainable Westchester Flat Rate Plan (2025)
- 100% Renewable Supply: 13.298¢/kWh (fixed through November 30, 2025)
- 50% Renewable Supply: 12.178¢/kWh (fixed through November 30, 2025)
- Supplier: Constellation New Energy
- Note: These rates do not include Gross Receipts Tax (GRT), which may be added depending on your municipality.
My Variable Constellation Rates (2025)
- Lowest monthly rate (Jan 2025): 10.8¢/kWh
- Peak monthly rate (Oct 2025): 13.5¢/kWh
- Average rate (Jan–Oct 2025): ~12.2¢/kWh
Cost Comparison: Flat vs. Variable Supply Rates in 2025
- The Sustainable Westchester flat rate for 100% renewable supply is 13.298¢/kWh.
- My variable rate with Constellation ranged from 10.8¢/kWh to 13.5¢/kWh.
- Most months in 2025, my variable rate was below the flat rate. Only in October did my rate slightly exceed the flat rate.
- On average, I paid less with the variable rate plan—but there is always a risk that rates could spike above the flat rate in the future.
Summary:
If you value predictability and want to support renewable energy, the Sustainable Westchester flat rate is a solid choice. If you’re comfortable with some risk and want to potentially save money, a variable rate plan may offer lower costs—at least based on my experience in 2025.
That’s it for now. Next post I’ll compare 2023 vs 2025 gas rates.
