Srp pilot project
SRP Pilot Project

  • Assessed smart meter technical viability and benefits

    • Smart meter performance and metrics

    • Self healing and network capabilities

    • Business impacts, benefits and opportunities

  • Partnered with Elster and self-implemented pilot effort using trained SRP employees

  • Scope

    • Elster Energy Axis system with ~500 REX meters

    • Contained service area of single family, patio and apartment residences


Srp pilot project1
SRP Pilot Project

  • Evaluation and Testing activities:

    • Billing read accuracy – standard, TOU and demand metering

    • Meter read performance – cumulative ‘received’ energy / voltage

    • Remote handling of service requests

    • Tamper, error and outage features and reliability

    • Self healing and multi-level repeating functionality

    • Remote programming

    • Network performance with different gatekeeper configurations

    • Network time synchronization

  • Verified data gathering and system features at 99.9%


Benefits business case
Benefits – Business Case

  • Labor Savings – Field activities

    • Reduced manual meter reading

    • Substantially reduced field visits with back office support

  • Reduced maintenance

  • Safety

  • Billing Efficiencies – provided flexibility

    • Flexible reads / billing dates with reduced estimation or support

    • Rate changes without meter exchanges

    • Ease for bill adjustments and validation

    • Summary billing opportunities

  • Revenue assurance –improved detection/monitoring

  • Potential for distribution management and operations

    • Outage restoration

    • Load forecasting and distribution loading/loss studies


Implementation
Implementation

  • Moderate and sustained smart meter installation

    • Implemented by meter route for smooth transition

    • Targeted distant or hard to reach territories first

    • Safety considerations

    • Considered capital constraints and existing meter life

  • Meter quality / testing program

  • Established Customer notification program

  • Concurrent integration with customer relationship system for billing and orders – recognized operating efficiencies

  • Customer focus – empowered the Customer to better manage usage

    • Provided Customers with information and benefits via SRP web portal - MyAccount

    • Expanded TOU rate offerings with ‘Smart data’ enabled rate design targeted at summer critical peak (EZ-3)
