ESA Comments: In the Matter of Resource Planning and Procurement in 2015 and 2016
In comments filed with the Arizona Corporation Commission, ESA would like to lend its support of comments filed by the Western Resource Advocates and the Southwest Energy Efficiency Project (“Joint Parties”). Specifically, ESA echoes the Joint Parties’ recommendations that additional and more thorough evaluation of energy storage is warranted in this Integrated Resource Planning (“IRP”) cycle and that utility assumptions about current costs and cost curves moving forward in the 2017 IRPs are in need of updating. Lastly, ESA provides recommendations on modifications to the resource planning process moving forward to ensure more effective consideration of energy storage.
