September 2026: what the register recorded
30 incidents dated September 2026 are on the register as of 2026-09-26: 20 at grid infrastructure, 4 at hybrid co-located, 3 at solar PV, 2 at battery storage, 1 at wind (onshore). 2 classed major, 18 significant. That is 19 more than August 2026 (11).
Read this as a count of what is recorded, not of what happened. Entries for a month keep arriving for weeks as reporting catches up and the recheck confirms them, so this page is regenerated on every build and the figures move. 620 entries were published during the month, most of them about earlier years; that number is not incidents in the month. The methodology says how entries are found and checked.
