Background & Transition

Jim Ko


Background transition

Background & Transition

  • Generator Interconnections Process

  • Existing Process

  • F2006 CFT Process

  • SGIP Process

  • Transition Rules

  • Q&A on the Processes and Transition Rules

IPP Educational Workshop


Generator interconnections process

Generator Interconnections Process

  • Interconnecting Generators to the Transmission System

  • Basic elements in all processes:

    • Preliminary or Feasibility Study (Optional)

    • Impact Study and Facilities Study

    • Facilities Agreement

    • Facilities Design and Construction

    • Interconnection Agreement

    • Commissioning and Commercial Operation

IPP Educational Workshop


Existing process

Existing Process

  • Comprehensive presentation on BCTC web

    http://www.bctc.com/generator_interconnection/transmission_generator_interconnection_process_chart.htm

  • Used by BCTC since its formation

    • Interconnection studies

    • Facilities agreements and Interconnection agreements

  • Will be replaced by OATT SGIP on March 1, 2006

  • Will continue to be used for projects that are grandfathered from the OATT SGIP process

IPP Educational Workshop


F2006 cft process

F2006 CFT Process

  • BCTC is currently conducting preliminary studies for CFT participants under this process

  • Grandfathered from the OATT SGIP process by BCUC order - as published in the BC Hydro F2006 Call for Tenders and on BCTC website

  • For the exclusive use of projects participating in the F2006 CFT - valid for as long as a project is a part of this CFT and not valid outside this CFT

  • Projects unsuccessful/withdrawn from the F2006 CFT will need to pursue interconnection under the OATT SGIP process

  • Projects that are selected by the CFT must execute a Combined Study Agreement and pay associated deposit within 60 days of the EPA award.

  • A new and different interconnection process will apply to CFT issued by BC Hydro subsequent to 2006. BC Hydro and BCTC are developing the process under BCUC directions in the OATT decision.

IPP Educational Workshop


Oatt sgip interconnection process

OATT SGIP Interconnection Process

  • Approved by BCUC in the OATT decision

  • Standard Generator Interconnections Procedures (SGIP)

  • Effective 1 March 2006

  • Different than the existing process

  • Details of the process and implementation will be covered in later slides

IPP Educational Workshop


Transition rules

Transition Rules

  • All Interconnection Agreements executed prior to the effective date of OATT SGIP will be grandfathered.

  • A new Interconnection Request under OATT SGIP may be required for modifications to existing generating facilities

  • Projects responding to existing BCH CFT will follow the interconnection process published in the CFT (F2006 CFT Interconnection Process)

  • Projects that have executed an Combined Study Agreement prior to the effective date of OATT SGIP may choose the existing process or the OATT SGIP process during March 2006.

  • Projects that have not executed a Combined Study Agreement prior to the effective date of OATT must use the OATT SGIP.

Key Differences – Current & OATT

Introduction

Introduction

  • This presentation is just an overview, the new tariff is the best reference for details.

  • Found at http://www.bctc.com/generator_interconnection/

    • Standard Generation Interconnection Procedures (SGIP)

    • Standard Generator Interconnection Agreement (SGIA)

    • Recovery of New Facilities Costs (Attachment K)

IPP Educational Workshop


Key differences

Key Differences

  • Application

  • Interconnection Types – multiple

  • Timelines

  • Facilities – definition and funding

  • Clustering

  • Request Queue / Public Info

  • Third Party Use

  • Study Scope

IPP Educational Workshop


Application deposit

Application Deposit

Difference: a $15K deposit is required along with the Interconnection Request

OATT Reference: Section 3.3.1

Key Terms: Site Control – show the right to “develop a site for the purposes of constructing the Generation Facility”

*note*

Demonstrating Site Control within 15 business days of the Interconnection Request makes the deposit refundable.

IPP Educational Workshop


Interconnection types

Interconnection Types

Difference:

NRIS – used when selling to BCH. Integrates generator facilities on same basis as BCH generation.

ERIS – used when planning to market energy independently

OATT Reference: Section 3.2

Note:

  • can request to be studied for both for greater flexibility

  • NRIS study potentially identifies more NU’s than ERIS

IPP Educational Workshop


Specific timelines

Specific Timelines

Difference: prescribed timelines for responses (Interconnection Customer and Transmission Provider)

OATT Reference: Section 3.6, 6.3, 7.4, 8.4 etc

  • Current process — requests can sit at a given stage

  • SGIP — a continuous process from start to finish

IPP Educational Workshop


Facilities definitions

Facilities - Definitions

Difference: current definition of Network upgrade is based on sole use and benefit, OATT SGIP definition is based on location relative to the Point-of-Interconnection (POI)

OATT Reference:

SGIP — Sec 1

SGIA — Sec 1, 5.10 & 11

Key Terms:

  • Network Upgrades (NU) – Sec 11.3 of SGIA

  • Point of Interconnection (POI)

  • Point of Change of Ownership (POCO)

  • Interconnection Facilities (IF)

  • Transmission Provider Interconnection Facilities (TPIF) – 5.11, 11.2

  • Interconnection Customer Interconnection Facilities (ICIF) – 5.10

Facilities funding security

Facilities – Funding & Security

OATT Reference: OATT Attachment K, 11.4 of SGIA

  • Customer funds the Interconnection Facilities and Transmission Provider funds the Network Upgrades (NU).

  • Customer provides security for NU.

  • Release / reduction of NU security

    • ERIS – reduction equal to LTF PTP charges.

    • NRIS – annually reduced for an amount equal to the annual output times the LTF PTP rate.

IPP Educational Workshop


Request clustering

Request Clustering

Difference: allows for the study of multiple Interconnection Requests concurrently instead of serially

OATT Reference: Section 4.2

Key Terms: Queue Cluster Window

  • for efficient planning and sharing of facilities costs

  • after the Feasibility Study stage

  • Benefits to be investigated as SGIP comes into use

  • No surprises – 180 day notice prior to window opening

IPP Educational Workshop


Queue position public posting

Queue Position / Public Posting

Difference: SGIP features a queue to establish explicit priority and makes the list of Interconnection Requests public

OATT Reference: Section 3.4, 4.1

Key Terms: Queue Position

Posted info: type of generator, size, ISD, location, POI, study reports

Queue establishes order for performing studies and cost responsibility for facilities.

Customer name will be held confidential until an interconnection agreement is signed.

IPP Educational Workshop


Third party use

Third Party Use

Difference: Interconnection Customer is entitled to pro-rata compensation for TPIF used by a third party.

Via TPIF – Third parties cannot be unreasonably prevented from connecting to the Transmission Provider Interconnection Facilities. Capital and ongoing expenses will be shared by users.

Via ICIF – IC can negotiate the new interconnection directly.

Use of NU – no entitlement or reimbursement.

OATT Reference: Section 9.9 of SGIA / 11.4.4 of SGIA

Study scope

Study Scope

Difference:

SGIP Interconnection Feasibility Study has a more restricted scope than the current Preliminary Study.

OATT Reference: Section 6

Note:

  • Quicker – 45 calendar days

  • Simpler – powerflow and short circuit analysis only
