Net Excess Generation Notes
  • HEC continues to credit excess energy from solar installations at the same rate as the customer purchases from HEC as long as the customer is generating less than 100% of their annual usage.
  • Customers that wish to generate over 100% of their annual usage, up to 200%, may also enter into a net metering agreement, however, the excess energy generated over 100% will be credited at HEC’s avoided cost of wholesale power.

System Offset Notes

On residential systems if you size over 100% then the customer will need to go on our other agreement where any generation over 100% would be credited to the account at an avoided cost rate instead of the retail rate.

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with Harrisonburg Electric before you rely on this. The useful move: if an installer says you need a main panel upgrade, ask how these tap and interconnection policies were considered first.
