Available in PDF, EPUB and Kindle. Book excerpt: The paper explores several market opportunities and challenges for pumped storage hydropower (PSH) related to ongoing changes in the electric power grid. Two PSH technologies are investigated - single-speed pump/turbine and variable-speed pump/turbine units - under three variable generation penetration scenarios. The results provide a way to do relative comparisons of the opportunities and challenges that pumped storage hydro faces as the variable generation in a system increases.
