Options Cost

Traditional ApproachTrim tree’s, replace equipment $6 - 12 M per loop

Smart Grid TechnologyLimit risk, add communications (fiber), and leverage technology

$2 - 4 M per loop

Both options produce similar SAIFI results for the first year

OutcomeA device based

program that has optimized

SAIFI reduction and spend

…will mitigate rising electric distribution SAIFI trends.

Targeting extended customers interrupted, a two part asset evaluation algorithm was

developed, modeled after our current inside plant CMMS system structure.

I. Incident Evaluator Algorithm:

Device Health Score provides the basis for an initial prioritization of potential projects, subject to further field inspections and cost estimates as described below.

SAIFI Yieldon Investment

(Yield Score)Remediation Cost Estimate

SAIFI Benefit Validation

• Scope of work assessment by field engineering /

asset management

– SAIFI benefit validation

– Remediation cost estimates

II. Field Inspection, SAIFI validation and Cost Estimates:

Scope of work assessment in field provides basis for cost estimate and validation of SAIFI benefit.

Benefits and costs form basis for SAIFI Investment Yield calculation and final prioritization of projects.
