College Station Automated Metering Infrastructure
- 1. Prepared by Schneider Engineering, Ltd. | ADVANCED METERING INFRASTRUCTURE PLANNING DISCUSSION
- 2. Presentation Goal Continue the conversation regarding advanced metering for the City’s electric and water utilities. Our presentation will address the following areas: o Review of AMI implementation in Texas / ERCOT o Discussions of the need / benefits of possible pilot project(s) o AMI features, benefits and costs – what functionality will consumers and CS Utilities realize? o Discussion and recommendations on how to proceed 2
- 3. Quick Review of AMI 3
- 4. What is Advanced Metering Infrastructure? Electronic meters with high-speed / two-way communications Various technologies / systems in the “advanced metering” industry Distinctions are related to the type of communication network utilized 4
- 5. Review of AMI adoption and implementation by utilities in Texas 5
- 6. Current AMI Status - Texas Investor-Owned Utilities (IOU) Drivers •2005: HB-2129 – “…PUCT shall establish a non-bypassable surcharge for IOUs to use to recover reasonable and necessary costs incurred in deploying advanced metering and meter information networks…” •2007: HB-3693 – “…it is the intent of the legislature that …advanced meter information networks be deployed as rapidly as possible to allow IOU customers to better manage energy use and control costs and to facilitate demand response initiatives.” Legislation • 2009: PUCT approves non-bypassable surcharge fees to pay for IOU advanced meter deployment. • IOU customers will pay those monthly fees from 2009 through 2020 Regulation 6
- 7. 7 1. IOUs have installed over 6 million AMI meters in Texas 2. CenterPoint Energy received a Smart Grid stimulus grant from DOE which covered approximately 50% of their AMI project implementation costs 3. SE is working to confirm end of surcharge timeframe Current AMI Status – Texas Investor-Owned Utilities (IOUs) Numbers Number of AMI Meters1 Deployment Complete Residential Surcharge Surcharge Timeframe CenterPoint 2.3 M 2012 $3.05 2011 – 20142 Oncor 3.0 M 2012 $2.19 2011 – 2020 AEP TCC 809 K 2013 $2.26 2011 – TBD3 AEP TNC 193 K 2013 $2.35 2011 – TBD3 TNMP 200 K 2016 $3.40 2011 – TBD3
- 8. Current AMI Status - Texas Public Power Situation Municipal Owned Utilities (MOUs) and Electric Cooperatives Local Control (no mandates) Cooperative segment were early adopters AMR/PLC (due to rural profile and associated meter reading costs) Drivers for AMI adoption / implementation • Linked to attainment of strategic goals • Failing 1st Generation AMR system • Operational and Customer Service benefits 8
- 9. 9 City / Utility Total Meters Number of AMI meters deployed Deployment Schedule San Antonio (CPS Energy) 740,000 electric Pilot program 40,000 in 2011 Started mid-2014 Full deployment by 2018 (RF Mesh) Austin (Austin Energy) 435,000 electric Full deployment 2004-2011 Bryan (BTU) 52,000 electric Full deployment 2012 (P2P) Denton (DME) 48,500 electric 44,000 to date Complete late- 2014 New Braunfels (NBU) 31,000 electric 29,500 water 0 Initial study only Georgetown (GUS) 23,000 electric 23,000 water Full deployment Completed recently (RF Mesh) Current AMI in Texas Public Power Deployment
- 10. Is there any need to pilot AMI? 10
- 11. To Pilot or Not to Pilot? Leading AMI manufactures all have operational systems that can be observed (nearby) The various types of AMI (difference communication technologies) are proven / mature technologies Pilots require significant communication, software / IT costs – whether it is 1,000 or 100,000 meters At this point – AMI Pilot projects are expensive and risky – and not necessary 11
- 12. AMI in College Station 12
- 13. Key Business Case Factors / Considerations 13 •Electric Meters: 10-15 years life •Meters have…more electronics…more plastic •Water Meters: Several variables / assumptions •Battery life impacted by number of reads per day / per month •Some manufacturers have 20 year accuracy guarantee and 10 year battery life guarantee—(prorated in years 10-20) Expected life of new “AMI Electric and Water Meter” •Elimination of manual meter reading •No more trips to connect /disconnect accounts (electric only) •Increased efficiency related to customer service and operations •Reduction in water losses (leak detection) Savings Drivers •Need additional IT, communications and meter /system techniciansOffsets to Savings
- 14. What will AMI in CS likely consist of? What will it do? Likely to select a Radio- Frequency based AMI system •Point-to-Point or Mesh •Backhaul with fiber, cellular or microwave Meter Data Management System •Manage all the interval data •Robust interactive consumer portal with graphs, charts, alerts Eliminate manual meter reading •Current annual cost is $372K •No need to go on consumer’s premise Remote connect / disconnect feature on electric meters •Current annual cost for manual service $73K Potential for utility to integrate AMI information and functionality •Reduce outage times / improve outage notifications •Support demand response / conservation voltage reduction •Improve system operations and planning •Provide data for Load/System Studies and Transformer Loading Studies •Enable new rate design(s) 14
- 15. Initial Project Costs - Estimate 15 AMI Component / Item Quantity Unit Cost Total Cost Comments Communication System (materials and installation) (Shared) 1 system $350K - $750K Depends on type of RF system selected Software / IT / MDM (Shared) Initial Setup $750K- $900K Upfront costs Electric Meters 40,000 $100 - $140 $4M - $5.6M Depends on type of RF system selected Electric Meter Installation 40,000 $15 $600K Water Meters 8,250 $60 $495K 25% of system has AMI compatible meters installed – just need a new registers 24,750 $140 $3.465M Water Meter Installation 8,250 $30 $247.5K 24,750 $60 $1.485M Total $11,392,500 – $13,542,500
- 16. Project Costs - Initial and Ongoing Initial Costs • $11.4 M - $13.6 M Ongoing Costs • Additional FTEs • $100K - $200K in annual licensing / maintenance fees Does this estimate square with IOU monthly charges ($2-3 per month on electric meters) ? • Yes. Counting both electric and water accounts – a $2.50 per meter per month charge equals $2.19M / year for CS • Recovery at this rate over 6 years equals $13.14M 16
- 17. Will Expected Savings Offset Costs? 17 •Savings related to the elimination of manual meter reading and trip costs for electric connects / disconnects equals approximately $.50/meter/month •These savings partially offset by additional O&M costs for AMI system (meter and communications technicians) •Hard to quantify / monetize: •Customer service benefits •Operational benefits (loss reduction, conservation voltage reduction and demand response) •Reliability benefits (reduction in outage times) •Water leakage reduction benefits •A detailed Business Case / Planning Study can get at some of this granular savings detail Hard to see how. Maybe over the life of the system..?
- 18. Where to go from here? 18
- 19. Current Situation No current statutory or regulatory mandate for College Station to have AMI metering system Current process / manual meter reading system is functional Other significant capital projects in the queue (ERP upgrade is scheduled thru 2015) Currently have a placeholder for an AMI system in the FY19 budget 19
- 20. Recommended Actions For a project of this size, complexity and magnitude A formal study is needed • Link to core strategies for reliability, affordability, safety and customer service • Determine (nail down) options, costs and benefits • Specify system type and functionality • Determine overall schedule • Plan for RFPs / AMI system selection and MDM system • Develop installation Plan (and RFP) • Plan for integration with IT, OMS, SCADA (other “Smart Utility” systems) • Start Study in FY17 20
- 21. Summary The City of College Station Utilities is in a good position related to eventual implementation of AMI for both the electric and water utilities 1. There is no mandate -- (it’s on your terms) 2. Time to evaluate, plan and “get it right” 3. Study, plan and engineer system in advance 4. Learn from the experience of other utilities 5. Monitor status of other CIP projects to ensure resources and funds available to take on AMI when time comes 21
