Meet rising energy demand without waiting for the grid. This session explores how data centers can secure fast, resilient capacity through investment‑light, dual‑fuel on‑site generation designed to operate in open cycle for FLEX connections and ancillary‑service participation. For longer bridge periods, the same architecture can evolve into high‑efficiency combined‑cycle with optional absorption chilling. A future‑proof pathway to reliable, flexible, and sustainable power across Europe and the UK.
