Diamond Generating Corporation is a subsidiary of Mitsubishi Corporation that develops, owns, and operates electrical generation facilities in North America. It has 11 operating facilities and is currently constructing two simple cycle plants totaling 1000 MW in California. The presentation discusses two of Diamond's projects - the 195 MW Mariposa Energy plant and 800 MW CPV Sentinel plant. Both projects went through California's rigorous Application for Certification process to obtain permits from the Energy Commission.
