Data as published by the named source on the stated date. N84 may contain matching or processing errors. Not investment, legal or technical advice. The official register prevails. Not a government service.
Every email has a one-click stop link.
Free sends this weekly, Pro daily or weekly, Team also as it happens. Only changes in newly retrieved files are sent; archived copies never are.
History held: NESO TEC Register since 31 May 2024, NESO Embedded Register since 7 Nov 2025, NESO Interconnector Register since 15 Feb 2022, SSEN Embedded Capacity Register since 1 Aug 2023, NGED Embedded Capacity Register since 14 Aug 2026. Paid plans show every edition in this list and no more; the list grows as earlier editions are collected.
How units work
Each API call costs units: a list or a single record 1, a timeline or a connection-site queue 2, the changes feed 1 per 100 changes returned (at least 1). The dashboard does not use units.
The rules
The dashboard is free with an account. You pay for depth: every edition N84 holds, more watches and faster alerts, CSV of a view, API volume and bulk data through the API. Annual billing first; monthly billing is offered on Pro. No VAT is charged. Cancel any time from the billing link; the plan runs to the end of the paid period. You have 14 days from payment to cancel and get a refund, less the service already provided.
Sold by N84 Labs. Enterprise and beta plans are invoiced.
