Webinar: Why Implement Active Power Curtailment on QF Sites?

How can QFs show they’re a valuable generation asset?

About the webinar

PV owners are concerned with keeping their sites running at maximum output. The problem is, utilities have the control to take them offline completely, and do so during grid instability, especially when it comes to small QF sites.

If implemented with the right controls, however, solar sites can actually avoid this curtailment. In fact, they can be commanded by those same utilities to run at lower output during times of grid instability. Small PV sites that have implemented active power curtailment controls are less likely to be shut off than larger sites without these types of controls.


It’s better for the utility to have QF sites at their disposal that can run at a low output on short notice. It provides a benefit to both parties. When other sites power back up, it’s less of a shock to the grid (which makes utilities happy) and it also allows smaller sites to provide a continual stream of revenue, even if reduced, to the site owner.


Avoiding curtailment

Active power curtailment isn’t just about the ability to flip a switch and turn a PV site on or off. It’s having the controls to adjust site output at any level between 0% and 100%. A control systems integrator, like Affinity Energy, has the know-how to implement these controls at QF sites.

The addition of controls to a solar project is pretty minor. But having a system that can respond slower and reduce grid disruption allows even small QF sites to make a difference on the grid.
