Smart Meter Cost Recovery

1 Smart Meter Cost Recovery Presented by Adam Cooper National Governor s Association Center for Best Practices Webinar #2: How will the Smart Grid be paid for? December 16, 2010

2 Utility-scale smart meter deployments, plans, and proposals about 65 million meters will be deployed over next 5-7 years. About 50% of US households. Deployment for >50% of end-users Deployment for <50% of end-users *This map represents smart meter deployments, planned deployments, and proposals by investorowned utilities and large public power utilities. IEE September 2010 update 2

3 Smart meters: What do we know so far? Several approaches for cost recovery Smart meters are a building block and an enabling technology for: Smart consumers, smart appliances, smart rates Distributed generation, Plug in hybrid electric vehicles, The smart grid. Smart meters are accurate Structure Consulting Group study of PG&E meters, Sept Navigant study of smart meters across Texas, Aug., 2010 Multiple other studies by utility companies. Utilities are getting some pushback on deployments 3

4 Cost Recovery Mechanisms Surcharges Approved tariff rider with true-ups (actual estimate) Removes regulatory lag, single-issue focus Rate Base Recovery Treated as capital expenditures Costs and benefits are collected and accounted for by the utility, but not recovered until future rate case Trackers Recovers cost as they arise Hybrid (Rate Base + Tracker) Track some costs and recover others thru rate base 4

5 Surcharge Example CenterPoint Energy (Texas) 2007: PUCT provides rules for smart meter functionality and cost recovery process Allowed for expedited cost recovery thru a surcharge Surcharge= Reasonable Cost Expected Savings Original cost recovery via monthly surcharge over 12 years $3.24/mo, first 24 months, $3.05/mo, June 2010 PUCT filing to reconcile AMS cost as of 3/31/10; reflect $150 M in DOE funding used on AMS Accelerate 5 year deployment to ~3 years ( ) Shorten residential surcharge from 12 years to 6 years 5

6 Cost Tracker Example Southern California Edison (CA) Cost: $1.633 Billion Deployment: ( ) Uses energy balance account with monthly reporting of the balance account Prudency review done prior to investment Significant planning process $1.633 billion of reasonable expenditures tracked through Edison SmartConnect Balancing Account Cost overrun up to $100M; 10% borne by SCE shareholders Costs exceeding $1.733B could be recovered in future rate case 6

7 Rate Base Recovery Example BGE (MD) Cost: $835 million Schedule: 3 years ( ) Establish regulatory asset for costs incurred net federal funding with costs to be recovered in future rate case post-deployment Previous case requested tracker Mandatory TOU withdrawn by BGE Focus on consumer education Decision seen as model to protect consumer interests BGE concerned with legacy cost of old meters 7

8 Smart meters: Why the pushback? Traditionally, utilities upgraded their infrastructure with little input from the public. However, smart meters are not the typical system upgrade. Why? Over hyped by vendors and media Federal government spending has sped up the process Some benefits occur in front of the meter; some behind the meter. Pushback Some examples PG&E - Bakersfield billing issues started in In September, installation halted in areas of Marin County. MD PUC concerns about BGE s deployment BGE s initial proposal rejected by PUC; refiled and accepted. BGE now rolling out smart meters. Duke Energy s proposal in Indiana for statewide rollout initially rejected; Duke moving forward with pilot. 8

9 Concerns raised regarding smart meters and smart rates* Smart meters must be cost effective Make dynamic pricing voluntary not mandatory Educate customers Maintain consumer protections Maintain privacy and security Verify investments *Source: AARP, NASUCA, et al. The need for essential consumer protections: smart metering proposals and the move to time-based rates, August

10 Smart meter platform & new home technologies will take demand side management to new levels It s all about giving customers the tools and the know-how to be smarter energy consumers. Educate, educate, educate! HAN communication SmartMeter communication 10

11 $ Billions Hey, ratepayers, can you spare a trillion? Meters represent $22 billion of $1.26 trillion less than 2% $250 $1,259? 1000 $ $500 $167 $22 $50-250B Carbon cost $40-120B for % compliance $120 0 EPA Compliance 15% RPS Compliance Transmission for RPS Smart Meter Nuclear Replacement Carbon Electric Car Total Potential Spend Assumptions EPA Compliance: $600/KW; RPS: 15% by 2020, Tranmission Cost 1/3 of RPS Spend; Smart Meter: 85% Implementation; Nuclear Repl acement: 25 GW Replacement at $8000/KW Source: "Impediments to Achieving the Vision," Dan Eggers, Presented to the Aspen Institute Energy Policy Forum July 3rd, Base d on Energy Velocity, NRC, Company Data, Credit Suisse Estimates. 11

12 Summary: Getting smart meters right is only a small part of the bigger picture Smart meters represent an integral part of a clean energy future and a more efficient grid. But, meters are only a small fraction of the future cost of developing clean power (1.7%) Is the debate over smart meters clouding the real issue? What does the high cost of developing clean supply side resources renewable energy, new nuclear, and clean coal mean for U.S. electricity prices? 12

13 Smart meters: Lessons learned Customer education and engagement are critically important Smart meters represent a new paradigm Especially important for low income customers Smart rates are one way to engage customers; information, social marketing, and real time load control are others Going forward, state regulators are asking/will ask for detailed customer communications plans This is a reasonable request 13
