Just Back from NARUC

Back from San Antonio.  The most interesting panel was a NASUCA panel called:

"Grid-Side Storage:  What do advocates need to consider when evaluating proposals to add battery storage to Utility Systems."

Not only is the topic relevant, but also three of the four panel members are from Arizona.  Residential Utility Consumer Office Director Jordy Fuentes moderated.  Then we had ACC Chairman Bob Burns and APS Vice President Barbara Lockwood. 

APS's announcement that it wants to install an additional 850 MW of batteries by 2025 has been made more complicated by a recent fire.   Obviously safety is their top consideration.  

Barbara Lockwood emphasized that batteries have to be affordable and reliable and that economics drives all of their planning decisions, but that the decisions are more complex than just cost.    

Chairman Burns said that the ACC is redesigning the IRP process to rely on my stakeholder input.  

If you have any questions about the presentation, give me a call.  


About the Arizona Competitive Power Alliance

In the late 1990s the forces of law, technology and economics intersected in a way that would be critical to Arizona's Future. Law:   FERC's order 888 guaranteed wholesale electric generators access to the electric grid.  Technology:  Combined cycle gas turbines with low heat rates and low emissions took advantage of low natural gas prices in order to produce power at marginal rates that were lower than incumbent utilities' coal fleets.  Economics:  Maricopa County consistently placed number one or two in the fastest growing counties in the nation.  

As a result of these forces, Independent Power Producers invested billions of dollars into Arizona by constructing a series of power plants in order to sell power throughout the western United States, and especially to Arizonans through Arizona Public Service and Salt River Project.  Independent producers eventually built enough generation that they could replace APS's entire generating capacity--twice over.  

In 2001 a group of these Independent Power Producers formed the Arizona Competitive Power Alliance.  They hired Greg Patterson* as the founding Director in order to represent them at the Arizona Corporation Commission and Arizona Legislature.

In the subsequent 18 years, the record has become clear;  Independent Power Producers have saved Arizona consumers hundreds of millions of dollars, provided increased electric reliability and flexibility all while paying millions of dollars in taxes to the state and local jurisdictions.  

Over the last 18 years, the AzCPA has participated in every APS rate case as well as Arizona Corporation Commission Rule Making proceedings, Integrated Resource Planning, Biennial Transmission Assessments and scores of workshops.  Throughout that time, the AzCPA has fought for open markets, increased competition and an opportunity to bid for the right to serve Arizona consumers.

A lot has changed since 2001.  Natural gas prices have become so low that coal plants are no longer economically viable.  Wind and solar power have become so cost effective that they are the lowest priced marginal resource.  Storage in becoming increasingly viable and cost effective.  

AzCPA members have evolved as well and AzCPA members continue to provide the most cost-effective resources to Arizonans.   Through the AzCPA, they will continue to fight for the right to compete in order to provide those resources.
