California is going through a dramatic energy transition. The state has set a goal to derive 100 percent of its electricity from carbon-free sources by 2045 and last week Gov. Gavin Newsom directed state agencies to look at moving the target up to 2035.

That means finding a way to eliminate greenhouse gas emissions from the state’s power grid while at the same time ensuring the power system remains reliable and affordable.

It’s a balancing act.
