Policy Analysis: MHHS Migration Impact on P2P Energy Suppliers
Executive Summary
Market-Wide Half Hourly Settlement (MHHS) will fundamentally change how electricity suppliers handle metering and settlement data. For P2P platforms like UrbanChain that match generation and consumption in real-time, the transition to half-hourly granularity creates both operational challenges and strategic opportunities.
Core Requirements
All licensed suppliers must complete M15 qualification testing by Q2 2026 under SLC 49.
Data Collection Agents must provide half-hourly consumption data for all meter points in the supplier's portfolio.
BSC credit cover calculations will shift to half-hourly settlement volumes, potentially increasing or decreasing exposure depending on portfolio shape.
Impact Assessment
Settlement Systems
P2P matching algorithms need upgrading to half-hourly granularity. Data pipeline changes required across metering and billing stack.
Credit Exposure
HH settlement may reduce imbalance exposure for well-shaped portfolios. UrbanChain's renewable matching could benefit from granular data.
Compliance Risk
Failure to meet MHHS milestones triggers Ofgem enforcement under SLC 49. Fines scale with supplier volume.
