ISO facilitates the timely installation and certification of revenue measurement and telemetry for participating production units. www.caiso.com/rules/Pages/BusinessPracticeManuals/Default.aspx Entities that generate electricity are (of course) essential to the grid. California has always had a wide range of types of generators and, in recent decades, they have always been renewable production (mainly hydrothermy and geothermal). In the 1980s, I participated in a project to set up a control system (then new) for the Geysirs geothermal complex. This complex was originally developed by PG-E and commissioned in the early 1960s. The geysers are now mainly operated by Calpine and are the largest geothermal field in the world, which includes a complex of 22 geothermal power plants and draws steam from more than 350 wells with a peak power of more than 1500 MW. It is located in the Mayacamas Mountains in an area that includes parts of Napa, Sonoma and Lake Counties.

I spent a lot more time studying how CAISO will handle solar and battery storage projects (where they are integrated into the same resource). This seems to be a decision being developed, even as solar developers start building big projects like this. In addition, there is (at least) a class of generators that seems to be a collection factor for system production resources that are not otherwise identified, a specific system resource (RSSR), so this may be where they fall in the short term.
The RSSR requirements are dealt with in point 4.12 and we will not specifically address these requirements. CAISO defines two classes of Utility Distribution Company. The first is the normal UDC, as used in the title of this subsection, and the other is a small utility distribution company (SUDC). The main difference between these companies is that the Small Utility Distribution Company has a peak annual need of 25 MW or less. I also expect that their requirements for interaction with CAISO will be less painful.
