As more renewable energy sources, like solar and wind, feed into the grid, prices can fluctuate due to their dependency on the weather. . Energy storage reduces price volatility by shifting cheap power to peak demand periods, but its total system cost is governed by thermodynamic losses and global material geopolitics. The cost of electricity is not determined by the price of the fuel you cannot see, but by the thermodynamic violence. . NLR analyzes the total costs associated with installing photovoltaic (PV) systems for residential rooftop, commercial rooftop, and utility-scale ground-mount systems. This work has grown to include cost models for solar-plus-storage systems. One area of particular interest is the way in which energy storage systems directly influence electricity prices.
