Constructing a 6,000 ton chilled water plant with Thermal Energy Storage Initial phase will be for 4500 tons based upon campus needs. • • Changes initiated by the customer (ACC) to include a well on site • Working towards obtaining Certificate Of Occupancy and • Cost of this change is approx. $1 million but will save several million addressing inspection punch-list items over the lifecycle of the plant • Turnover to AE Operations anticipated in August 2021 • Final completion of project altered by 4 months • Beneficial use of the plant will be October 2021 • On-Target for substantial completion in Q4 2021 Mueller Energy Center #2 (Mueller Redevelopment Zone) Constructing a 6,000 ton chilled water plant with Thermal Energy Storage • Project still in the design phase. • Plant status under evaluation due to budget increase • Decision how move forward is InProgress. 11 Austin Energy Operational Update Future State 12 Grid Resilience AE Strategic Goals 2020-2025 Grid Resilience Improve Distribution System Reliability Identify, Rank, and Address feeder maintenance needs in areas historically beset by outages. Identify, Rank and Address system hardening needs in areas most susceptible to wildfire risk. Phase I – Top 10 Feeders in both Performance and Wildfire Criticality addressed (CY/2021) Improve Substation Reliability Evaluate substation equipment operation and address legacy equipment needs. Phase I - Fiskville Substation Upgrades (COMPLETE) Phase II- Slow Breaker Operation – Review, Rank and Schedule Substation Breakers for maint. and remediation Improve Underground Network Reliability Starts with enabling greater Visibility to our downtown network through the integration of our network model into our Advanced Distribution Management System Phase I - Network fully Modeled in ADMS – (Q3/2020) (COMPLETE) Phase II - Enhance model through GIS/ADMS to increase system mapping and visibility- Primary– (Q2/2021) (COMPLETE) Phase III - Enhance model to increase system mapping, visibility; support analysis of load and flow (Q1/2022) Transmission System of the Future As part of the 2030 generation plan, Austin Energy is commissioning a Transmission system study that will investigate ways to achieve our goals set forth in the plan while compensating for the loss of generation plants. Phase I - Development of evaluation criteria (Q1/2021) (COMPLETE) Phase II – Develop SOW for RFP release (Q3/2021) (COMPLETE) Phase II – Evaluating RFP bid responses (ongoing) 13 Austin Energy Operational Update Appendix 14
