What are we doing to green the grid?

The ISO is committed to supporting important energy and environmental policies while maintaining reliability through a resilient power grid system.

Installed renewable resources  

The installed renewable resource values reflect the reporting Net Dependable Capacity only (numbers are rounded). Only fully commercial units are counted, not partials or test energy, as reported via the Master Generating File and captured in the Master Control Area Generating Capability List found on OASIS under “Atlas Reference”.

Integrating renewables reliably

The ISO is focused on the reliable integration of zero-emission resources such as solar and wind power in support of the state's renewables portfolio standard.

Policy perspectives

The century-old electric grid is evolving into a modern and sophisticated machine to unlock a greener economy and fight off global warming. Coordinating the alignment of environmental and energy goals is critical to developing a cleaner, reliable and more weather-resilient power grid. The ISO is collaborating with state and federal agencies, policymakers, stakeholders and end-user groups during this historic transformation to meet the challenges and opportunities ahead.
