Abstract

Power system decarbonization requires utility-scale energy storage, with Brownfield Pumped Hydropower Energy Storage (B-PHES) proposing a dual solution for grid stability and post-mining recultivation. While B-PHES sites may exhibit substantial geometric storage potential, current evaluation frameworks rarely integrate hydrological pit flooding dynamics in sedimentary basins, despite their decisive role in determining the feasibility of pit lakes as lower reservoirs of B-PHES plants.
