Glenmarie electricity substation explosion reported in Shah Alam

EIR-1278

Provisional entry. A news report and social-media footage describe a substation explosion in Glenmarie during flooding and possible blackouts in Shah Alam, but the report said there was no official confirmation of the site, cause or outage. Next update: 26 September 2026.

Video posted online was reported to show the Glenmarie electricity substation in Glenmarie, Shah Alam, producing a large ball of fire and several explosions during flooding. A news report said the explosion was believed to have contributed to blackouts across Shah Alam, and that the footage had been reported to Tenaga Nasional Berhad. The report said there was no official confirmation at the time of writing.

The footage was described as showing the explosion during a flash flood. A causal link has not been officially confirmed.

  1. Treat flood-related substation reports as unconfirmed until the operator or authorities verify the site, cause and outage impact.
  2. Review flood exposure and isolation arrangements for substations in flood-prone areas.
  3. Keep a clear channel for public reports of substation fires during extreme weather, without treating them as confirmed findings.
