Summary
The RCCS Methodology defines how costs for redispatching (RD) and countertrading (CT) of cross-border relevance are shared between TSOs in Capacity Calculation Region (CCR) Hansa. Required under CACM Regulation Art. 74. Developed jointly by all CCR Hansa TSOs; each national NRA must approve amendments.
Amendment history: original approved February 2019; amended March 2021, October 2022, and this version November 2024.
What the 2024 amendment adds: NorNed (NO2–NL) and NordLink (NO2–DE/LU) were added to CCR Hansa by ACER Decision 08/2023 (31 March 2023) and were missing from the cost-sharing methodology. The amendment adds them at 50%/50% (Statnett/TenneT). Also renames “Regional Security Coordinator” → “Regional Coordination Centre” throughout. No other material changes.
CCR Hansa — bidding zone borders in scope
Since ACER Decision 08/2023 (March 2023), CCR Hansa covers eight bidding-zone borders:
| Border | Interconnector | TSOs | Sharing key |
|---|---|---|---|
| DK2–DE/LU | Kontek | Energinet, 50Hertz, Vattenfall AB | Southbound 585 MW: 190/195/200; Northbound 600 MW: 1/3 each |
| Krieger’s Flak CGS | — | Energinet, 50Hertz | 50%/50% (wind forecast error: responsible party pays) |
| DK1–DE/LU | — | Energinet, TenneT TSO GmbH | 50% / 50% |
| SE4–PL | SwePol Link | Svenska Kraftnät, PSE S.A. | 50% / 50% |
| DK1–NL | COBRAcable | Energinet, TenneT TSO B.V. | 50% / 50% |
| SE4–DE/LU | Baltic Cable | Baltic Cable AB | 100% |
| NO2–NL | NorNed | Statnett, TenneT TSO B.V. | 50% / 50% |
| NO2–DE/LU | NordLink | Statnett, TenneT TSO GmbH | 50% / 50% |
Cost-sharing principles
Three situations, three different rules:
1. HVDC technical limits, fault/failure, or KF wind forecast error → costs split between owners of the relevant interconnector per Annex 1 sharing key above.
2. Operational security analysis identifies congestion (normal case) → costs covered by the TSO in whose control area the physical congestion took place. This is the most common situation. It creates a direct financial incentive for TSOs to manage congestion in their own control area — letting it develop becomes costly.
3. Cross-CCR requests → same principle: TSO in whose control area the congestion took place.
The Baltic Cable 100% rule
The SE4–DE/LU sharing key assigns 100% of costs to Baltic Cable AB. Every other CCR Hansa interconnector uses 50%/50% or thirds. This means:
- When redispatching or countertrading is needed to relieve congestion on the SE4–Germany link, Baltic Cable AB bears the full cost
- No sharing with Svenska kraftnät or German TSOs for this link’s congestion costs
- The rationale is not explained in the methodology text; likely reflects the unique private ownership structure of Baltic Cable AB (the cable is privately owned, unlike most public TSO-operated interconnectors)

| Wiki page | Connection |
|---|---|
| Baltic Cable | 100% cost rule for SE4–DE/LU redispatching/countertrading costs |
| Congestion Management | Cross-border cost-sharing framework; “physical congestion location” principle creates incentive for TSOs to manage domestic congestion |
| Flow-Based Capacity Calculation | RCCS Methodology is the cost-sharing complement to the flow-based capacity calculation methodology for CCR Hansa |
| Svenska kraftnät | Proposed the amendment; operates SwePol Link (SE4–PL) at 50%/50% cost sharing with PSE |
| ACER | ACER Decision 08/2023 expanded CCR Hansa to include Norwegian interconnectors |
