Interconnector Operator (ICO) Update

Jean-Gabriel Valentin (RTE)

ifa capacity management system user interface
IFA Capacity Management SystemUser Interface
  • The new system is proposed to be the sole commercial interface for Users for all IFA activity, including:
    • Conducting auctions
    • Users’ Mid-Channel Nominations (MCNs)
    • All general communications (results, ICEs, specifications, curtailments, general queries/notices etc)
  • IFA will require a single Mid-Channel Nomination
    • unlike current practice of nominating identical MCNs to both TSOs
  • Access to be via web-based format (secure, reliable, and using ETSO ECAN protocols)
ifa capacity management system next steps
IFA Capacity Management SystemNext Steps
  • Dec 07 Tenders invited
  • March 08 Contract award
  • *September 08 Product testing
  • *October 08 Commercial operation

*note – chosen Supplier capability will determine precise Go-Live date.

  • In spring 08 a further User workshop will be held to update Users on business process and interface issues.

losses relevant issues
LossesRelevant Issues
  • GB Market ≠ French Market
    • GB: Market Participants responsible for losses
    • Fr: RTE pass through all losses (except IFA) to consumers
  • Direct Current ≠ Alternating Current
    • AC: System line loss small in meshed network
    • DC: System conversion losses notable
  • NGET (TSO) ≠ NGIL (ICO)
    • NGIL (Interconnector Licence) not permitted to trade energy; cannot mitigate or pass through energy exposure
    • NGET (Transmission Licence): to take on losses for another BSC party is not resolving an imbalance issue in GB Market; outside Licence

losses potential options1
LossesPotential Options
  • GB Market ≠ French Market
    • Harmonise GB & French market arrangements?
  • Direct Current ≠ Alternating Current
    • Appropriate to consider harmonisation of IFA with other French AC borders?
  • NGET (TSO) ≠ NGIL (ICO)
    • Consider varying NGIL’s Interconnector Licence / NGET’s Transmission Licence?
  • Users already factor losses into the value of IFA capacity
    • Purpose of harmonisation?
losses conclusion
LossesConclusion
  • No change proposed to current losses arrangements on IFA
firmness potential harmonisation aspects
FirmnessPotential Harmonisation Aspects

IFA (Direct Current)

  • ATC = NTC = Rating
  • F2E = E2F Capacity
  • No Security Standards
  • No circuit redundancy
  • Reconcile at 100%
  • Force Majeure 100%

Other French AC Borders

  • ATC ≤ NTC < Rating
  • F2x ≠ x2F Capacity
  • Security Standards applied
  • Full circuit redundancy
  • Reconcile at 110%
  • Force Majeure 0%
firmness relevant issues
FirmnessRelevant Issues
  • IFA Risk ≠ Risk on Other French AC Borders
    • No European Grid Code to cover DC IFA
    • UCTE Handbook covers Other French AC Borders
    • Appropriate to consider harmonisation in FUI region?
  • NGET (TSO) ≠ NGIL (ICO)
    • Firm NGIL-NGET Connection to Firm GB Market
    • NGIL (Interconnector Licence) not permitted to trade energy; cannot mitigate or pass through energy exposure
    • NGET (Transmission Licence): to take on risk for another BSC party is not resolving an imbalance issue in GB Market; outside Licence
firmness options
FirmnessOptions
  • IFA Risk ≠ Risk on Other French AC Borders
    • Consider harmonisation across ETSO
    • Network Access & Congestion Management Task Force
  • NGET (TSO) ≠ NGIL (ICO)
    • Consider varying NGIL’s Interconnector Licence / NGET’s Transmission Licence?
  • Who is best placed to mitigate curtailment?
    • Curtailment is typically in increments of 500MW
    • Curtailment is proportioned across all User MCNs
nacm task force firmness
NACM Task ForceFirmness
  • Sub-group to Task Force led by E.On
  • Several interconnections to be studied
    • IFA, IFB, IFD, P-Cz, D-P, D-DW, B-NI, D-NI, D-CH
  • Analyse curtailments for 2006 CY data
    • Classified as caused by:
      • Internal AC Network
      • Interconnector assets
firmness study on interconnectors draft curtailment data 2006

IFA Curtailment Commentary*

AC Borders

Asset related maintenance/faults have not curtailed cross-border capacity because of Security Standards (UCTE Handbook) therefore redundancy in interconnection capacity

Unplanned Trips/

Reductions

Short-Notice Planned Outages

Annual Outages

* Discrete curtailment events shown (not duration)

Switching transitions 500MW / 1000MW not listed individually

Firmness Study on Interconnectors Draft Curtailment Data 2006
firmness summary
FirmnessSummary
  • CM Guideline
    • Optimisation of firmness
    • Combination of Firm & Non-Firm capacity allowed
  • Medium-Term Harmonisation Potential
    • ETSO NACM Task Force
  • Short-Term Harmonisation Potential
    • Firm & Non-Firm capacity
      • Include as option for settlement functionality in CMS specification
      • Consult IFA Users on combination of Firm/Non-Firm capacity
settlement invoicing current proposed
IFA Current

Products invoiced individually, with different payment terms

Products offered/invoiced at Target Availability, reconciled on last payment

Considers Users’ cash flow against IFA service delivery

Equivalent to 100% compensation

IFA User Proposal

Consolidated monthly invoices for all products, harmonised payment terms

Products offered at 100% availability, reconciled monthly for outturn

Considers Users’ cash flow against IFA service delivery

Equivalent to 100% compensation

Settlement & InvoicingCurrent & Proposed
intraday transfer limits itls current proposed
IFA Current

ITLs set after D-1 nomination

ITLs do not impact Users’ Interconnector Entitlement (ICE) at D-1

ITLs can restrict Users’ ability to re-nominate intraday if MCN < ICE

IFA Proposal

ITLs set after D-1 nomination, before Intraday allocation

ITLs will not impact Users Interconnector Entitlement (ICE) at D-1

CM Guideline (applying UIoSI/ UIoLI) will ensure MCN = ICE

Clarification underway regarding ITLs for intraday capacity

Intraday Transfer Limits (ITLs)Current & Proposed
use of interconnector fee so so trades
Use of Interconnector FeeSO-SO Trades
  • NGET (TSO) ≠ NGIL (ICO)
    • NGIL cannot subsidise NGET, or vice versa
    • NGIL must levy a fee for ‘Use of Interconnector’ capability post gate closure
  • Options for Fee basis
    • Market-based
      • Associate with retro-direction D-1/intraday auction clearing price?
      • Associate with arbitrage value?
    • Non-market-based
      • Is there a market to participate in, post gate closure?
      • Product (I/C capability) is variable by nature – how to value?
  • No change proposed to current arrangements
