A Major Step Towards Energy ModernisationSri Lanka is poised to take a significant leap forward in its energy sector, with commercial-scale Battery Energy Storage Systems (BESS) expected to be connected to the national electricity grid as early as September this year. What Are Battery Energy Storage Systems? Battery Energy Storage Systems are large-scale technology solutions designed to store electrical energy and release it to the grid when demand is high or supply is low. The government has set ambitious targets to increase the share of renewable energy in the national power mix, and large-scale battery storage is considered an essential component of achieving that goal reliably and efficiently. The integration of Battery Energy Storage Systems is widely regarded by energy experts as a critical enabler for countries looking to scale up renewable power without compromising grid reliability.
