Launch of CAISO’s Energy Imbalance Market Marks a Smooth transition for EnSuite and PG&E.

CAISO’s semiannual release schedule has seen two exceptionally busy schedules, with the spring release of the FERC 764 market revisions, and the fall release of CAISO’s new Energy Imbalance Market (EIM). Each release has brought major revisions to the structure of CAISO energy settlements, including the fifteen-minute market charges mandated by FERC 764 and a large group of new and modified charge codes with the inception of EIM. The release of the EIM market changes represents the second major market update that Northern California utility PG&E has managed since installing EnSuite Settlements.

In each case, EnSuite Settlements managed the change with aplomb. “EnSuite is designed from the ground up to manage this type of market change.” said EnDimensions CTO Elene Radinskaia, “In both the fall and spring releases, the changes to charge validation and shadow calculations were handled without compiling a single line of code. This allows for a clean and trouble-free transition for our customers, without disrupting system availability or the customer’s daily business process. In most cases, updates can be installed transparently to the user, and without shutting down the system.”

COO Ryan Heidari noted, “As we progress with our partners at PG&E, each market update cycle reinforces our confidence that the fundamentals of the EnSuite Settlements design are solid; Our aim with EnSuite is to provide a robust, full featured product suite that reduces long-term cost of ownership and supports our commitment to innovation and refinement that continually adds value to the product. Leveraging its modular design, we can now also offer an EnSuite product targeted toward EIM market participants who do not require the full scope of ISO settlements.”
