Allows specific sites within a group to be marked as "inactive" if they are experiencing abnormal behavior (like maintenance), preventing them from skewing the group's baseline data. By reducing financial risk, P376 encourages more independent

Instead of using that potentially inaccurate FPN, Elexon now uses a Baselining Methodology . This looks at a site’s historical behavior to calculate what its energy flow would have been without the intervention, ensuring more accurate compensation.

, formally titled "Utilising a Baselining Methodology to set Physical Notifications," is a modification to the UK's Balancing and Settlement Code (BSC) . Approved by Ofgem and managed by Elexon , it aims to level the playing field for smaller, flexible energy providers—such as demand-side response aggregators—participating in the Balancing Market. The Problem: The "Physical Notification" Barrier This looks at a site’s historical behavior to

Understanding P376: The Shift to Baselining in Energy Settlement Introduction

Implements standardized algorithms (like the BL01 methodology) that account for differences between working days and weekends.

If the FPN was inaccurate, these providers could face financial penalties for "non-delivery," even if they successfully delivered the requested energy service. The Solution: Decoupling Dispatch and Settlement
