Forecast headroom (MW) for demand, inverter-connected and synchronous generation at every UKPN grid (BSP) and primary substation, per DFES 2025 scenario, from the baseline year to 2050.

What is withheld, and why

Nothing is withheld. Values are served with the attribution the licence asks for: UK Power Networks, Distribution Future Energy Scenarios Network Scenario Headroom Report (DFES NSHR), https://ukpowernetworks.opendatasoft.com/explore/dataset/ukpn-dfes-network-headroom-report/. Keep it with any figure you show.

UKPN's portal terms prescribe the attribution as the company, the dataset name, its URL and the date of last update; the date travels beside the attribution as freshness.source_effective_at. The same terms prohibit use of the UKPN logo. technical_access is unknown until a key exists: what a valid key unlocks is untested.

UKPN Network Scenario Headroom Report (DFES 2025, LTDS November 2025 baseline)

gb_ukpn_dfes_nshr_2026 · v2026-05

Unused firm substation capacity (MW) per year and DFES scenario, from LTDS November 2025 network loading and the Distribution Future Energy Scenarios 2025; demand headroom against the latest firm capacity, generation headroom against LTDS equipment ratings.

Capacity basis: operator calculated
Network state: unknown
Binding: No
Additive across assets: No — do not sum these figures
The method accounts for: reserved: not stated · allocated: not stated · pre-reserved: not stated · pending requests: not stated
Comparability class: gb_ukpn_nshr
Documentation: Operator’s method (opens the operator’s site)

The operator’s own caveats

please note unused capacity may be contractually committed to customers.
Those seeking connection should contact our connections gateway to understand the latest view of available capacity.
more capacity may be available for customers on a non-firm, flexible or curtailable connection.

notes: ["One value per record: headroom_mw for one substation, category, scenario and year. category maps demand to offtake / generic_load, and inverter-connected and synchronous generation to injection / generic_generation with the operator's split kept as the variant (inverter_connected, synchronous). A category with none of those words is refused, not filed under the nearest.","Firm: UKPN defines the value as \"unused firm capacity; negative values indicate a deficit\" and says the headroom tables are based on firm capacity. Negative values are kept and flagged.","Horizon: target_year from the year field (baseline year and forecast years), with the DFES scenario as published (Holistic Transition, CounterFactual, Electric Engagement, Hydrogen Evolution).","Identity: site functional location plus LTDS substation name, because split busbars of one site are published separately. The functional location is kept as an attribute and not offered as a cross-source identifier, since split busbars share it.","headroom_percent (of firm capacity) and demand_rag are kept in each value's details, not as capacities.","Written against the published schema; exact category strings and year formatting are unverified until a keyed run."]
