A Peek Into California’s Energy Future: Grid Operator Releases 20-year Outlook

A long-range outlook released by California’s grid operator offers a glimpse at what the state’s electric system may look like in 20 years — a portfolio with dramatically more renewable energy sources in the power mix, accompanied by a price tag of about $30.5 billion in transmission costs alone.

The California Independent System Operator, known as the CAISO for short, manages the electric grid for about 80 percent of the Golden State and a small part of Nevada. Every year, the organization conducts an annual transmission analysis and then updates its 10-year planning horizon.
