Solar Power
Member Generated Power
More than 800 OPALCO members are generating renewable energy tied to the OPALCO electric grid. You can produce renewable energy at your home or business and become an interconnected member with solar, wind, micro-hydro or other small-scale renewable resources.
Getting Started
Preapproval for interconnection to the OPALCO grid is required. Please review the entire Interconnect Packet before continuing.
Contact Solar Installer
OPALCO doesn’t recommend specific installers, but we do have a list of local installers to help you get started.

Review the policy
The policy covers interconnection of any member owned generating facilities, storage facilities or other facilities supplying energy to the OPALCO grid.
Please read Member Service Policy 13 for more information.
Fill out the application and agreement
Pay special attention to requirements. Projects must meet OPALCO Interconnect Standards. Presently, 200 kilowatts is the maximum size for a system.
How Interconnection Works
The most common topic we discuss with new Member Generators is how OPALCO keeps track of their locally generated power, and how generated and consumed kWhs are reflected on their monthly bill.
An important point to understand is Member Generators have two separate meters – a billing meter and a production meter.
Bi-Directional Billing Meter
A Member Generator’s billing meter is the meter presented on their monthly OPALCO bill. It measures two things:
- The flow of electricity from the grid toward the house (power the household consumes from OPALCO)
- The flow of electricity “backward” (what their renewable system feeds back to the OPALCO grid when the system produces more power than the household needs)
When you deliver energy to the grid, you will receive a credit on your next bill. This will be noted on your bill as a Generation Credit. You will carry that credit until you use it all up and start consuming more power than you are generating.
Production Meter
The production meter accounts for every kWh the member’s renewable system generates. This meter reading represents total kWhs produced and is indifferent to the way the power is distributed (whether to the member’s home or to the OPALCO grid).
If the member participates in state and local production incentive programs, OPALCO obtains a reading from the member’s production meter annually on June 30th to calculate the incentives.
Local Contractors: Solar
Members are fully responsible for selecting and coordinating with contractors. The contractors listed are familiar with OPALCO’s programs and policies. OPALCO does not endorse any contractor. Here’s a list to get you started:
