CAISO Study Claims $1.5 Billion in Savings From Potential Creation of Western Market
July 13,2016
The California Independent System Operator (ISO) released a final study on the potential effects of creating a multi-state, regional wholesale electric market in the West.
The study claims that customers would save $1.5 billion by 2030 under the expanded market.
Savings are from: (1) savings from reduced capital investments for RPS-related procurement; (2) reduced production, purchase, and sales costs for wholesale electricity; (3) reduced capital investments from regional load diversification; and (4) reduced grid management charges for system and market operations
The study analyzed the bookends for the scope of a regional market: at one end, a regional market that consists only of CAISO and PacifiCorp in 2020; and at the other end, an expanded regional ISO that includes most of the U.S. portion of the Western Electricity Coordinating Council
Consumer Watchdog denounced the study as a "snow job" written to justify the use of California ratepayers to build new plants and transmission to allow utilities to profit from exports. Consumer Watchdog said that a regional market, "would once again commoditize electricity, divorce the costs of generation from the needs of ratepayers, and threaten consumers with higher costs to benefit investors."
