          "Under the flagship \"Delivering a Secure, Sustainable Electricity System\" (DS3) operational framework, the transmission system operators can now reliably manage System Non-Synchronous Penetration (SNSP) levels of up to 85%.",
          "The report highlights that the addition of 1,020 MW / 2,100 MWh of operational BESS provides sub-second Fast Frequency Response (FFR), while utility synchronous condensers at Moneypoint and Shannonbridge inject crucial physical inertia and short-circuit fault current."

          "Unlike previous winter seasons marked by capacity margin tightness, the coordinated dispatch of grid storage, demand-side response, and 110 kV static VAR compensators secures adequate generation adequacy margins throughout peak evening periods.",
          "The report validates the role of inverter-based flexibility in stabilizing isolated island electricity grids."
