Estimate only. Uses your state's average residential rate for May 2026, assumes supply is about 55% of your all-in rate, and applies a 30% reduction to the supply portion alone. Delivery charges don't change. Your actual rate depends on your utility, your usage pattern and the plans available where you live.
