This medium-voltage electricity is then channelled through various distribution feeders to smaller primary substations and pole-mounted transformers. These secondary facilities step the voltage down further to the standard 230 V required for residential and commercial consumers.		The Galle Grid Substation is a transmission-level node.

	The '''Galle Grid Substation''' (also called '''Bataduwa Grid Substation''') is a {{Nowrap\|132 [[Volt\|kV]]}} electrical [[substation]] located in Bataduwa, near [[Galle]], in the [[Southern Province, Sri Lanka\|Southern Province]] of [[Sri Lanka]]. The facility serves as a distribution gateway for the [[Galle District]], stepping down high-voltage power from the national transmission grid for regional distribution. The substation is owned and operated by the state-owned National Transmission Network Service Provider (NTNSP). The site is notable for hosting Sri Lanka's first commercial-scale [[battery energy storage system]].<ref name="Newswire-BESS-1">{{cite news \|title=Sri Lanka begins Battery Storage Era with first 10 MW BESS – NPP MP \|url=https://www.newswire.lk/2026/09/12/sri-lanka-begins-battery-storage-era-with-first-10-mw-bess-npp-mp/ \|access-date=27 September 2026 \|publisher=Newswire \|date=12 September 2026}}</ref><ref name="Newswire-BESS-2">{{cite news \|title=Sri Lanka’s first commercial‑level Battery Energy Storage System joins National Grid in Galle \|url=https://www.newswire.lk/2026/09/15/sri-lankas-first-commercial%E2%80%91level-battery-energy-storage-system-joins-national-grid-in-galle/ \|access-date=24 September 2026 \|publisher=Newswire \|date=15 September 2026}}</ref><ref name="Newsfirst-1">{{cite news \|title=Sri Lanka To Commission Galle BESS Today \|url=https://www.newsfirst.lk/2026/09/20/sri-lanka-to-commission-galle-bess-today-20 \|access-date=27 September 2026 \|publisher=[[Newsfirst]] \|date=20 September 2026}}</ref>		The '''Galle Grid Substation''' (also called '''Bataduwa Grid Substation''') is a {{Nowrap\|132 [[Volt\|kV]]}} electrical [[substation]] located in Bataduwa, near [[Galle]], in the [[Southern Province, Sri Lanka\|Southern Province]] of [[Sri Lanka]].
