Standard Settlement Configuration

The Standard Settlement Configuration (SSC) is a four-digit field found in positions 3-6 of the newer 22-digit MHHS-format MPANs. It replaces the legacy three-digit MTC (Meter Timeswitch Code) and provides a nationally standardised settlement configuration.

Key facts about SSC:

Position in MPAN:

• MHHS MPANs (22 digits): Positions 3-6 (four digits, after Profile Class)
• Legacy MPANs (21 digits): Not present (use MTC instead)

Why SSC was introduced:

• Legacy MTCs were DNO-specific and inconsistent
• SSC provides industry-wide standardisation
• Supports the Market-wide Half-Hourly Settlement (MHHS) reforms
• Removes regional ambiguity in settlement processing

SSC values:

• 0000 - Default/not applicable (common during transition)
• Other four-digit codes map to specific settlement rules defined by Elexon

Relationship to MPAN length: The extra digit in SSC (4 vs MTC's 3) is why MHHS MPANs are 22 digits instead of 21.

Impact on EnergyCode: SSC is captured when parsing MHHS-format MPANs but doesn't directly affect DUoS tariff determination - that's still handled by the LLFC.
