Value Stack Calculator
NY-Sun developed the Value Stack Calculator to help contractors better estimate compensation for specific solar and energy storage projects. The calculator combines the wholesale price of energy with the distinct elements of distributed energy resources (DERs) that benefit the grid: the avoided carbon emissions, the cost savings to customers and utilities, and other savings from avoiding expensive capital investments.
We periodically update the calculator—please revisit this page regularly to ensure you are using the most recent version. To download the calculator, you will need a recent version of Microsoft Excel (older and web-based versions of Excel may have performance issues). The password to unlock the file is nysun.
