Emporia Energy offers two features for managing your EV Charger's energy consumption: PowerSmart and Peak Demand Management. Here's how to choose between them.
PowerSmart
Prevents your home's electrical system from exceeding supply limitations by dynamically adjusting EV Charger rates
Ideal for you if:
You have limited electrical service capacity (100A or 200A panels) and want to avoid service upgrades
You regularly use multiple high-consumption appliances alongside your EV Charger
You want to charge at the highest possible rate without exceeding panel limits
Important notes:
Requires an Emporia Energy Monitor (Vue 2 or Vue 3)
Cannot independently manage multiple EV Chargers on a shared circuit
Only monitors main service lines, not individual branch circuits
Peak Demand Management
Helps avoid costly utility charges by staying below peak demand pricing thresholds.
Ideal for you if:
Your utility charges are based on peak demand
You want to automate energy savings during high consumption periods
You have multiple smart devices connected to your Emporia system
Key features:
Supports multiple connected devices (EV Chargers, Smart Plugs, Thermostats)
Allows prioritization of devices when approaching peak demand thresholds
Requires an Emporia Energy Monitor (Vue 1, 2, or Vue 3 with 200A CTs)
PowerSmart vs. Peak Demand Management: A Quick Comparison

Primary Focus | Total system load | Utility pricing thresholds |
Devices Supported | Single EV Charger | Multiple smart devices |
Energy Monitor Required | Yes (Vue 1, 2 or Vue 3 with 200A CTs) | Yes (Vue 1, 2, or Vue 3 with 200A CTs) |
Automatic Control | Adjusts EV Charger charge rate | Controls multiple devices based on priority |
Use Case | Limited electrical panel capacity | High utility peak demand charges |
Which Should You Choose?
Choose PowerSmart if your concern is keeping your home's electrical system within safe limits without upgrading your panel. May be required for local code compliance.
Choose Peak Demand Management if your goal is to manage energy costs by avoiding peak demand pricing tiers.
