The California Independent System Operator (ISO) — in November — launched Siemens' (NYSE: SI) energy market management software to support the operation of the growing western Energy Imbalance Market (EIM). The software allows utilities across a broad footprint to more efficiently exchange and share energy resources, including renewables like wind and solar, based on generation and demand needs.
Siemens software is a component of the EIM system that allows the ISO to analyze the energy requirements of the grid every five minutes and automatically determine the lowest-cost generation to meet demand while maintaining the security of the grid.
A report released in April 2015 shows $5.26 million in benefits for the first quarter of 2015. This resulted in a benefit of over $11 million in five months for the ISO and its first and current participant, Pacificorp, whose serves customers in six western states — California, Oregon, Washington, Utah, Idaho and Wyoming.
