READ MORE1 Introduction. As renewable energy penetration increases on a grid scale, the issues of intermittency and price control continue to grow. One method for tackling these issues is relying on large-scale storage technologies to provide grid flexibility [].Previous studies have investigated using large-scale storage to perform services like
READ MOREThe opposite effect is true of the high renewable energy cost scenarios; specifically, high renewable energy costs lead to a greater demand for natural gas, which in turn leads to higher prices. Thus, one of renewable energy''s effects on the annual average marginal energy price is its impacts on the demand for natural gas.
