How Net Metering Works in Connecticut (UI & Eversource Explained)

If you’re a Connecticut homeowner considering solar, one of the most important things to understand is net metering. It’s the policy that determines how you get credited for the extra electricity your solar panels produce—and it can make a major difference in your long-term savings. In simple terms, net metering allows you to send unused solar energy back to the electric grid and receive credits that offset your future electric bills.

What Is Net Metering?

Net metering is a billing system that tracks the difference between:

• The electricity your home uses from the grid

• The excess solar energy your system sends back to the grid

When your solar panels produce more electricity than your home is using (for example, during sunny afternoons), that extra energy doesn’t go to waste. Instead, it flows back into the grid and earns you utility bill credits.

Later—like at night or during winter—you can use those credits when your system produces less energy.

Think of it like a running energy bank account with your utility company.

How Net Metering Works in Connecticut

Connecticut has strong net metering policies, but the exact credit system depends on your utility provider:

• UI (United Illuminating)

• Eversource Energy

Both utilities follow state-regulated net metering rules, but there are small differences in how credits are tracked and rolled over.

UI vs. Eversource: What’s the Difference?

⚡ United Illuminating (UI)

• Credits are tracked monthly

• Excess credits roll forward to future months

• Annual reconciliation determines final payout or carryover

• Typically more straightforward monthly tracking system

⚡ Eversource Energy

• Credits also roll month to month

• Annual “true-up” period determines remaining credit value

• Some homeowners see seasonal fluctuations reflected more clearly

• Slightly more detailed breakdown of usage vs. generation on bills

👉 Bottom line: Both utilities offer net metering, but your billing statement layout and credit timing may look slightly different.

How Do Credits Actually Work?

Here’s a simple example:

• Your solar system produces more electricity in July (sunny summer month)

• You export extra energy to the grid

• You receive credits in kilowatt-hours (kWh)

• In January, when production is lower, you use those credits instead of paying full price for electricity

Over time, this helps balance out your yearly energy costs.

💡 Important note: Credits are usually applied at the retail electricity rate, meaning you’re effectively getting full value for the energy you produce—not wholesale pricing.

Why Seasonal Production Matters in Connecticut

Connecticut homeowners see a clear seasonal pattern:

☀️ Summer

• Longer days = higher solar production

• Often generates excess credits

• Ideal “banking season” for energy credits

❄️ Winter

• Shorter days + snow cover can reduce production

• Homes rely more on stored summer credits

This seasonal balance is one of the biggest advantages of net metering. Your system is designed to perform over a full 12-month cycle, not just month to month.

What Happens at the End of the Year?

Both UI and Eversource typically conduct an annual reconciliation (sometimes called a “true-up”).

At this point:

• Remaining credits may roll over

• Some unused credits may be compensated at a lower rate (depending on utility rules)

• Your account resets for the next cycle

This is why system sizing and usage analysis matter so much—proper design ensures you maximize credit usage before the year resets.

Connecticut Solar Incentive: Net Metering + Bill Review

One of the most valuable steps before going solar is understanding your actual energy usage and how net metering applies to your home specifically.

That’s why we offer:

🔹 Free Net Metering & Utility Bill Review

We analyze:

• Your monthly kWh usage

• Seasonal consumption patterns

• Potential solar offset

• Estimated credit accumulation under UI or Eversource

This helps you see exactly how much of your bill could be offset with solar—before you commit.

Why This Matters for Homeowners

Net metering is what makes solar financially effective in Connecticut. Without it, excess energy would have little value. With it, every extra kilowatt-hour your system produces works toward lowering your future bills.

For many homeowners, this means:

• Lower or significantly reduced electric bills

• Protection against rising utility rates

• More predictable long-term energy costs
