Blog: The Universal Market Participation Model
Read More: Blog: The Universal Market Participation ModelA new FERC order, while ostensibly addressing energy storage resources, actually provides an important opportunity to create a universal data model for all grid resources. The traditional way of looking at generators and loads is no longer sufficient. We should take advantage of this opportunity. FERC Order 841 requires electricity markets to create an energy…

Blog: DER Compensation, Solar Integration and Rate Reform
Read More: Blog: DER Compensation, Solar Integration and Rate ReformGrowing penetrations of distributed solar under net energy metering (NEM) have spurred debate, and in some cases, changes to how distributed solar will be compensated in the future. Perhaps just as importantly, these debates have highlighted the need for rate reform more generally. In an age when airline prices can motivate you to spend the…

Blog: How Low Can You Go? VG and Minimum Generation Problem
Read More: Blog: How Low Can You Go? VG and Minimum Generation ProblemThere’s probably a hundred things to get “right” when performing simulations of VG integration. From transmission to reserve requirements to high-quality, spatially diverse VG profiles, each element of an integration study can radically impact estimates of curtailment and other important performance metrics. One key parameter for a good integration study is the minimum generation level…

Blog: Bulk Solar PV is Different
Read More: Blog: Bulk Solar PV is DifferentSo why is bulk solar PV different? Should it be? I think many of us who have been attending UVIG meetings over the past ten or fifteen years were surprised by the explosion of solar PV in the US and around the world. We shouldn’t have been, in my opinion, as we had front row…
