FERC Order 890 Principles & NTTG Straw Concepts Coordination

: Three level Local, Sub-regional & Regional Coordination

Openness

: Open architecture and stakeholder/customer process, unfettered Board

Transparency

: Data, criteria, ATC methods, etc. disclosure to all customers/stakeholders

Information Exchange

: Planning information coordinated and open; exchanged with WECC, IRPs, Stakeholder/customers, other Planning groups; native load, NT & PTP data exchanged on comparable basis

Comparability

: All similarly situated customers/stakeholders equal in processes

Dispute Resolution

: NTTG ADR to use WECC ADR with member agreement to use for planning related disputes

Regional Participation

: Participation in WECC TEPPC, NWPP’s NTAC, coordination with neighboring sub-regional planning groups

Economic Studies

: Economic and re-dispatch/congestion studies in planning cycle that influence plan; incorporates direction and analysis from Transmission Use committee

Cost Allocation

: Multi-state Cost Allocation Committee to develop and apply cost allocation principles 12

Related: Re-Dispatch & Conditional Firm N on-Rate Terms & Conditions (PR 901-1164)

– TP is obligated to offer Planning Re-Dispatch and/or Conditional Firm • If Long term Firm ATC is not available – “Planning” Re-Dispatch: Can be requested by PTP customer if less expensive than expansion – “Reliability” Re-Dispatch: Re-dispatch of network resources to avoid curtailment of network load – TP to provide “estimates” for re-dispatch, conditional firm, & expansion costs • Ex-Ante

(Latin for “beforehand”)

owned resources – TP is required to post: estimates required for: – Planning Re-Dispatch costs (non-binding) – Hours & conditions for firm service for Conditional Firm – TP required to provide Planning Re-Dispatch with own generation. However, if Re dispatch is insufficient from owned generation: • Must identify re-dispatch options on “others” generation within & outside Control Area • Must Coordinate between TP, third party generator & customer – TP also obligated to offer Conditional Firm • If Planning Re-Dispatch is insufficient (or doesn’t meet customer requirements) from TP • Re-dispatch costs & offers of re-dispatch from other’s generation –

Issues with Planning

• •

Planning studies required to include economic studies to ID congestion & re-dispatch $ Identification of Re Dispatch options on other’s systems

• • •

Consistency with Economic and Congestion Planning studies, especially in Base Case Need to align products (i.e. conditional firm) across multiple control areas Reconciliation of posted actual costs with congestion studies

NTTG Planning Straw Proposal -

Key Features Two step planning & implementation process to inform stakeholders and facilitate implementation of individual or joint projects

• Open architecture structure with Planning Committee open to all interested parties.

• Provides stakeholder/customer input and review process to evaluate transmission service and upgrade alternatives without formal OATT service request process. • Informs stakeholders on technical performance, benefits, costs, and potential cost allocation of individual and joint plans • Provides stakeholders/customers analysis of economic benefits (as well as reliability) of projects to inform their decisions on formal service requests and participation • Within present OATT responsibilities & framework, gives practical level of up-front cost certainty • Provides method to batch or cluster requests for economic studies • Provides estimates of benefits of aggregated requests in common areas, re-dispatch costs, and congestion 14

•

NTTG Planning Process Key Features, continued Three level integrated process produces synchronized, coordinated single system plan with local, sub regional, and regional stakeholders; and neighboring systems.

• Augments member Transmission Provider’s OATT service request study processes. • Utilizes WECC & WECC TEPPC for congestion and economic studies, base cases, other • Coordinates with neighboring planning groups via – direct coordination, – joint study teams, – and through WECC • Stakeholder and member triage process to determine study priority. Process similar to NRTA voting class org.

• Utilizes NWPP TPC’s NTAC to – identify overlapping projects effecting parties outside NTTG but within NWPP footprint, – Identify & establish joint study teams; – Help triage NWPP footprint study requests to WECC TEPPC.

NTTG Planning Process

Key Features, continued Informed customers can individually or jointly on aggregated basis submit OATT service requests

– Via aligned and open season service request process on NTTG member systems – Multiple party and multiple system requests that would be individually uneconomic

Balanced Steering Committee

– Composed of member transmission provider execs & footprint State regulatory and consumer agency representatives.

– CREPC type decision process with NTTG dispute resolution utilizing WECC ADR

Cost Allocation Committee in Planning Step (Following)

– Comprised of State regulatory & consumer staff, member representatives – Develops and applies cost allocation principles, determines cost allocation for projects included in the Plan approved by the Steering Committee

Planning Process meets 9 principles and philosophy of FERC Order 890

16

NTTG Planning Process

Key Features, continued

•

Transmission Planning & Use Committee coordination

– Consistent definitions of products • Service types, margins, POD & PORs, ATC definitions • Among NTTG Companies • Between NTTG Planning & Use analysis – ATC Coordination • analysis generated study requests & study request aggregation • Frequency of ATC determination and coordination with planning cycles – Website posting of re-dispatch costs & generation re-dispatch availability • Compilation & validation of re-dispatch costs for NTTG resources & modeling for TEPPC/SRPG database – Coordination and Development of: • Data submittal processes and standards for use with WECC and TPs • Subregional TP Re-dispatch & Conditional Firm system impact studies with Regional congestion studies – Pooling of re-dispatch & CF studies 17

Proposal Development

Cost Allocation Principles Work Group

– Created by Steering Committee • Response to Order 890 Planning Principle 9 • NTTG Planning Framework – Starting Point: CREPC White Paper • Transmission Regulatory Principles Work Group – Work Group Products • Steering Committee discussion draft 4/13 • Revised draft 5/15 28

Cost Types

Type 1: Provision of retail service to transmission owner’s native load

– 1-A Single LSE/Single State – 1-B Single LSE/Multi-State – 1-C Multi LSE/Single State – 1-D Multi LSE/Multi-State – 1-E Specific Retail Customer or Customer Group • Provide Service • Lower Costs • Increase Quality of Service 29

Cost Types

Type 1 Purposes

– Provide capacity to serve load – Fulfill reliability or technical operating requirements – Lower costs to consumers – Fulfill Federal or State policy requirements 30

Cost Types

Type 2: Provision of Wholesale Services (FERC Jurisdictional)

– Sales & purchases – Generator request – Transmission service request

Mixed purposes – Types 1 & 2

– Potentially mixed jurisdiction 31

Cost Types

Type 3: Alternatives to/Deferrals of Transmission Line Costs

– Usually Type 1 Costs – Distributed Resources

Important Distinction between Projects & Cost Types

– Any given project may have multiple cost types!

32

Principles

Principle 1: Equity

– Cost causers = cost bearers – Beneficiaries pay

Principle 2: Efficiency

– Supports federal and/or state resource choice policies – Efficient & stable resource planning processes 33

Principles

Principle 3: Fair & Full Cost Allocation

– Reasonable opportunity for full cost recovery,

but no more

– Order 890 deems this principle critical – Multi-jurisdictional allocations – Not an automatic reallocation mechanism in the event of less than full cost recovery 34

Principles

Principle 3A: Cost Assignment Follows Benefits

– Elaborates on Principle 1 – Direct cost assignment costs to single or multiple transmission customers based on benefits distribution

Principle 3B: Customer Specific Allocation

– Type 1-E Costs 35

Principles

Principle 4: Allocation for Wholesale & Merchant Project Costs

– Type 2 Costs – Outside Scope of NTTG Cost Allocation – FERC Jurisdictional 36

Process

Cost Allocation Committee

– Appointed by state agency and publicly and consumer-owned NTTG members – Process dovetails with Planning process – Input from NTTG members & stakeholders through public process – Steering Committee: Final say & dispute resolution 37

Process

Interface with Planning Process

– Study Plan Development & Study Phases: Preliminary & Iterative Analysis – Plan Report: Recommendations

Responsibility for Providing Sufficient Information

– Project developers, requestors, other interested stakeholders – NOT THE COMMITTEE!

38

Process

Step 1: Application Step 2: Review & Response Step 3: Analysis during Planning Process Step 4: Recommendations for Plan Report Steps 5 - 7: Steering Committee

• Determination Letter – Plan & Cost Allocation • Project Updates/Additional Review • Dispute Resolution 39

Issues/Comments?

Cost allocation v. cost recovery Risk analysis Reliability benefits Interface with future State & Federal regulatory proceedings Negotiated cost allocations Others???
