Spill PPAs are ideal for projects that have not yet reached commercial operations or for projects that use a significant amount of their generation onsite.
All of our PPA products include commissioning periods for projects that are not yet operational. However, if the output from your project will be volatile then this may be the best PPA for you as you won't need to notify us of changes to the project’s availability.
In a Spill PPA, we pass-through a percentage of the System Sell Price (SSP) as well as agreed terms for renewable certificates and embedded benefits. The SSP is a price calculated by the National Grid for each half-hour period for exported generation that is “spilled” to the grid.
