ISO Today is a free mobile application developed by California Independent System Operator Corporation. It is designed to provide users with real-time information about the California ISO power grid conditions, prices, and renewable production. With ISO Today, users can stay informed about the state of the power grid, receive alerts, and track calendar events related to energy.

The main features of ISO Today include the ability to monitor available resource adequacy capacity, view grid status and available capacity, and track renewables and supply graphs. Users can also monitor emissions, view wholesale energy prices on a price map, and compare demand and net demand plus historic data. The application also allows users to receive Flex Alerts, which notify them when conservation is needed.
