Independent Power Producers (IPPs), Renewable Electricity Producers, and Investor-Owned Utilities (IOUs), to name a few, are increasingly interested in sustainability metrics to evaluate solar, wind and battery storage projects. Just as buildings can be evaluated and receive green building certification such as LEED, more tools and processes are available to similarly evaluate infrastructure projects including renewable energy projects. There are several types of tools and metrics. In this session, we take a close look at some of them. We work with participants to examine how these tools are designed, the metrics they have devised, and some of the details regarding how they measure success and offer certification. We examine several case studies and discuss in detail the pros and cons of using sustainability metrics for solar and battery storage projects.
