As the world continues to emphasize the importance of energy conservation and cost-efficiency, having real-time access to electricity prices can make a significant difference for both residential and commercial consumers. While ComEd provides a basic five-minute pricing page, it often lacks the detailed visualization and user-friendly features that can help consumers make informed decisions. That’s where our new web application comes in.

Why I Built This App

The primary motivation behind developing the Real-Time ComEd Hourly Pricing Display was to create a more interactive and informative platform for tracking electricity prices. ComEd’s own five-minute pricing page provides raw data but lacks the dynamic features that many users desire. my web app aims to fill this gap by offering real-time updates, interactive charts, and a user-friendly interface.

Key Features of The App

Real-Time Data Updates

The application fetches data directly from ComEd’s API every minute, ensuring that you always have access to the latest pricing information. This frequent update cycle means you can react quickly to changes in electricity prices, optimizing your energy usage and potentially saving on costs.

Dynamic and Interactive Charts

Unlike ComEd’s static data display, the app uses Chart.js to create dynamic bar charts that visualize price changes over time. The charts are interactive, allowing users to hover over data points to see detailed information. The x-axis labels are formatted to show time in a 12-hour format with AM/PM indicators, making it easier to read and understand.

Visual Alerts

To provide immediate visual cues about pricing conditions, the app changes the background color based on the current price:

  • Light Red: When the price is above 10 cents/kWh, indicating higher costs.
  • Light Green: When the price is 5 cents/kWh or below, signaling more affordable rates.

These visual alerts can help you quickly assess whether it’s a good time to increase or decrease your energy usage.

Easy-to-Read Labels

All labels on the charts are black and slightly larger than standard, improving readability. This small but significant change ensures that users can easily read and interpret the data, even on smaller screens or from a distance.

Mobile-Friendly Design

My app is designed to be responsive, ensuring that it works seamlessly on various devices, including smartphones, tablets, and desktops. Whether you’re at home or on the go, you can always stay updated with the latest electricity prices.

Technical Details

Our app is built using a combination of PHP for the backend and HTML/CSS/JavaScript for the frontend. Here’s a quick overview of the technical implementation:

  • Backend: A PHP script fetches data from the ComEd API every minute, ensuring that the latest pricing information is always available.
  • Frontend: The HTML/CSS/JavaScript code leverages Chart.js to create dynamic and interactive charts. The page automatically updates every minute to reflect the latest data.

Conclusion

The Real-Time ComEd Hourly Pricing Display offers a more comprehensive and user-friendly way to track electricity prices compared to ComEd’s own five-minute pricing page. With real-time updates, interactive charts, visual alerts, and a mobile-friendly design, our app helps you stay informed and make better decisions about your energy usage.

I invite you to try out our app and experience the benefits of having real-time electricity pricing information at your fingertips. For more information and other projects, check out my YouTube channel.
