Decision framework

Separating real load from speculative load.

  1. G1

    Does the requester control land and capital?

    PASSAdvance to study.

    FLAGDiscount in forecast.

  2. G2

    Is the request duplicated across utilities?

    PASSDe-duplicate across territories.

    FLAGCount at full probability.

  3. G3

    Can existing transmission serve it at N-1?

    PASSPlan distribution only.

    FLAGTrigger transmission plan.

  4. G4

    Does the tariff protect existing ratepayers?

    PASSProceed.

    FLAGRevise large-load terms.

How Stock & Milster helps

Independent intelligence for planning and executive teams.

Decision-grade deliverables

  • D01Independent load growth read by territory
  • D02Peer-utility posture comparison
  • D03Large-load tariff and policy intelligence
  • D04Data-center pipeline de-duplication
  • D05Infrastructure planning support

Questions leadership brings to us

  • How does our load formation compare to peers?
  • What is the realistic cadence of AI load in our footprint?
  • How are peers structuring large-load tariffs?

Stock & Milster advises on the decision. We do not sell the project. Engagements are scoped to geography, facilities and depth of analysis.
