How It Works

1

Connect Your Tesla Powerwall

Sign in with your Tesla account. Takes 2 minutes. We use Tesla's official API - your password is never shared.

2

Let Tesla Optimize or Automate

Let Tesla's autonomous mode use the synced rates, or create custom automations that trigger on price thresholds.

Why ComEd + Powerwall + BatteryProfit?

Real-Time Rate Sync

We fetch ComEd's 5-minute real-time prices and push them directly to your Powerwall's tariff settings. Tesla's autonomous mode can then optimize based on actual rates.

Day-Ahead Planning

ComEd publishes tomorrow's predicted prices each evening. We sync these to your tariff so Tesla can plan overnight charging during the cheapest hours.

Custom Automations

Want more control? Create automations that trigger on price thresholds - like setting reserve to 100% when rates spike above 10ยข/kWh.

Solar + Battery Optimization

Have solar panels? We factor in your production forecast to maximize self-consumption and minimize grid purchases during expensive hours.

Understanding ComEd Hourly Pricing

What is Hourly Pricing?

Unlike flat-rate plans, ComEd's hourly pricing charges you the actual wholesale electricity rate, which changes every hour based on supply and demand. Prices are typically lowest overnight (1-5 AM) and highest during peak demand (4-8 PM).

Why It's Perfect for Powerwall

With a battery, you can buy electricity when it's cheap and store it for later. BatteryProfit keeps your tariff in sync so Tesla's autonomous mode has accurate rate data to work with.

Typical Price Patterns

Summer afternoons often see prices spike to 10-20+ cents/kWh during heat waves. Overnight rates can drop below 2 cents. That spread is where your savings come from.

No Guesswork Required

We sync both day-ahead (planning) and real-time (actual) prices to your tariff. Tesla's autonomous mode and your automations respond to real rates.

Simple, Affordable Pricing

$19.99/year

That's $1.67/month. Most ComEd hourly pricing customers save that in a single day.

Frequently Asked Questions

How does ComEd hourly pricing work with a Tesla Powerwall?
ComEd hourly pricing charges you the real-time wholesale electricity rate, which varies every hour. With a Powerwall, you can charge your battery when rates are cheap (typically overnight and midday) and use stored energy when rates spike (usually 4-8 PM). BatteryProfit syncs ComEd rates every 5 minutes to your Powerwall's tariff, so Tesla's autonomous mode can optimize based on actual prices - or you can create custom automations.
How much can I save?
Illinois Powerwall owners on ComEd hourly pricing typically save 20-40% on electricity compared to flat-rate plans. The exact savings depend on your usage patterns and the price spread between peak and off-peak hours. Summer months with high air conditioning demand often see the biggest savings.
What's the difference between day-ahead and real-time pricing?
Day-ahead pricing is published the evening before and shows predicted hourly rates for the next day. Real-time pricing is the actual rate you pay, updated every 5 minutes based on current grid conditions. BatteryProfit syncs both - using day-ahead for planning overnight charging and real-time for immediate decisions during the day.
Do I need to manually check ComEd rates?
No. BatteryProfit automatically fetches ComEd rates every 5 minutes and pushes them directly to your Tesla Powerwall's tariff settings. Tesla's autonomous mode will use these rates to optimize, or you can create automations that trigger on specific price thresholds.
I'm not on hourly pricing yet. Should I switch?
If you have a Powerwall, hourly pricing is usually a great choice. You can shift your consumption to cheap hours using your battery. Check ComEd's hourly pricing program details and compare historical rates to your current plan. Most Powerwall owners see significant savings after switching.
