CAISO Raises Pay for Replacement Power, Inches Up Budget

14 Dec

The grid operator’s board Dec. 14 approved allowing more flexible resources to come online soon after unexpected transmission disruptions. The newly approved modeling enhancement at issue also would increase the compensation paid to resources that come online quickly to rebalance the system. “This has the potential to increase reliability and reduce costs,” said Eric Hildebrandt, […]

New Western Grid Entity on Horizon

JUICE: Grid Familiarity

24 Oct

If California becomes part of a western grid, is the vehicle important? Specifically, is it better for the California Independent System Operator to formally grow or for western states to join an expanded Southwest Power Pool? While nobody expects the Southwest Power Pool to ever reach California, there’s growing concern about the pool expanding into […]

The Buzz

20 Oct

Greening the grid is the talk of the town. At the CAISO’s annual confab held this week, most bets are that a westward grid expansion will happen. Why? Because proponents insist it will promote renewables, which will decarbonize both the grid and economy, near and far. Achieving that goal, however, requires paying new alternative resources […]
