A new visualization tool from Berkeley Lab allows users to explore trends in wholesale electricity prices and their relationship to wind and solar generation. Variable renewable generation can have important impacts to pricing patterns at the local level, but those patterns are often obscured when looking at regional average annual pricing trends.
The Renewables and Wholesale Electricity Prices (ReWEP) tool allows users to compare pricing trends across locations, regions, and a number of different timeframes, down to the nodal level. These comparisons illustrate the ongoing interactions between wind and solar generation and wholesale energy prices.
