Value of Distributed Energy Resources (VDER)

Guided by the principles of Reforming the Energy Vision (REV), the Value of Distributed Energy Generation Phase One Decision [PDF] was released by the Public Service Commission in March of 2017, and the Phase One Implementation Order [PDF] was released Sept 14, 2017. This new methodology takes the first step in moving beyond Net Energy Metering (NEM) to a more accurate valuation and compensation of Distributed Energy Resources. VDER factors include the price of the energy, the avoided carbon emissions, the cost savings to customers and utilities, and other savings from avoiding expensive capital investments.

VDER Value Stack Calculator (NEW)

The Value Stack Calculator was developed to provide an accurate estimate of a PV project’s compensation under the Value Stack.

The Value Stack Calculator will be periodically updated and revised: please check back periodically. It requires a recent version of Microsoft Excel.

Locational System Relief Value (LSRV) Zone Maps

The below proposed LSRV maps are broken out by utility. The LSRV zones, capacity caps, and values were approved by the Public Service Commission in the September 14, 2017 VDER Implementation Order.
