1. An electricity generation system that uses multiple engine powered generators to provide electricity to a grid;
wherein the engines are modified automotive engines;
wherein the electricity generation system provides electricity to the grid when there are shortfalls in electricity supply from variable renewable electricity created from wind and/or solar energy;
wherein the engine powered generators are disposed in truck transportable container power modules that each includes multiple engine powered generators;
wherein the maximum power produced per power module is at least 1 MW;
wherein each of the container power modules weighs less than 20 tons;
wherein the electricity generation system comprises more than one power module;
wherein the power generated by the electricity generation system can be varied by turning engines in the power modules on and off and/or by turning power modules on and off;
wherein at least one engine is powered by a gaseous or liquid fuel; and
wherein at least one of the automotive engines is a spark ignition engine operated with a stoichiometric fuel/air ratio and uses a three-way catalyst for reduction of NOx emissions.
