Solar Renewable Energy Credits

Solar Renewable Energy Credit (SREC) marketplace allows solar owners to sell the environmental attributes of their solar energy to interested buyers.  This is an expansion of the existing Oneota Tag Carbon Offset program and helps support the work of the Winneshiek Energy District.

What is an “SREC”?

SREC is a Solar Renewable Energy Credit. It is the environmental attributes associated with the production of 1-megawatt hour (or 1,000-kilowatt hours) of electricity. Your solar array produces slightly more than 1-megawatt hour per year per kilowatt of installed capacity. This means that a 10-kilowatt array will produce approximately 10 SRECs each year.

An SREC must be registered with a reputable tracking agency in order to be sold. In this case, your PV system is registered by the Winneshiek Energy District in the Midwest Renewable Energy Tracking System (M-RETS), which enables the tracing and transferring of your SRECs. All you do is provide your system information and annual production data.

How does this program work?

The Winneshiek Energy District will buy SRECs from you and other northeast Iowa solar owners and sell them to groups and individuals wishing to reduce their carbon footprint.

In addition to the cost savings you already receive from generating your own power, you will also receive an additional check each year from the Winneshiek Energy District based on the number of SRECs you create.

*You can opt out of all agreements at any time by contacting the Winneshiek Energy District at: (563) 382-4207.



Why shouldn’t you sell your SRECs?

If you are already tracking your carbon footprint you may not want to sell the environmental attributes of your solar energy in order to avoid double-counting emissions reductions. You can’t have your cake and eat it too.
