- The impact of COP21 and growing renewable generating capacity are driving new behaviors and technologies; an increasing proportion of intermittent resources require power systems to adapt to large fluctuations in both supply and demand to maintain grid stability. - The GE hybrid electric gas turbine (Hybrid EGTTM) addresses these challenges, coupling a 10-megawatt battery with a 50-megawatt GE LM6000 Gas Turbine, operated by an integrated digital turbine control system. - Key benefits include “spinning reserve” without firing the gas turbine utilizing near instantaneous battery power through inverters, enhanced primary frequency response and voltage support, reduced greenhouse gas emissions, smooth transient response with less turbine thermal stress, thereby lowering maintenance costs, and lower T&D congestion.
