The Problem
Slow portals
Elexon Insights and NESO require knowing what to search for. Regional constraint data is buried in settlement tables.
Raw data, no context
BOALF data shows actions. Carbon Intensity API shows intensity. Neither shows how one region compares to another, or whether today is unusual.
Fragmented sources
A complete regional picture requires Elexon, NESO, and N2EX. Five sources, five tabs, no integration.
Who It's For
Battery storage developers
Understand regional constraint patterns before committing to grid connection applications that cost £50,000-£250,000 to initiate.
Planning consultants
Evidence regional grid conditions in planning submissions and client reports with sourced, timestamped data and full methodology documentation.
Energy brokers
Support client conversations about flexible tariffs and demand response with regional grid data updated every 30 minutes.
