This Article introduces a framework to assess water systems as potential sources of energy flexibility using energy storage metrics and levelized costs.
As can be seen from the table, while the initial costs of pumped water storage may have been $100/kW, those estimates are all from the 1970's. Once adjusted for inflation, the capital cost ranges from $353/kW to $2,216/kW (2000 dollars) with median cost of about $615/kW, a 20% premium on the cost of a natural gas turbine.
Energy intensity and electricity costs vary considerably across the water sector 19, 20; electricity typically represents approximately 30–50% of advanced water treatment lifetime costs, 60–80% of distribution and transmission costs and 20–30% of wastewater treatment costs 20, 21, 22.
Here we present a unified framework for representing water asset flexibility using grid-scale energy storage metrics (round-trip efficiency, energy capacity and power capacity) and assessing the technoeconomic benefits of energy flexibility at the water facility scale (levelized cost of water and levelized value of flexibility).
Nature Water 2, 1028–1037 (2024) Cite this article Water systems represent an untapped source of electric power load flexibility, but determining the value of this flexibility requires quantitative comparisons to other grid-scale energy storage technologies and a compelling economic case for water system operators.
Provided by the Springer Nature SharedIt content-sharing initiative Water systems represent an untapped source of electric power load flexibility, but determining the value of this flexibility requires quantitative comparisons to other grid-scale energy storage technologies and a compelling economic case for water system operators.
Providing energy services (for example, demand response, frequency regulation and so on) may advance the worthy goal of enhancing system affordability, but the degree of energy flexibility in the water asset, and the extent to which flexibility is deployed, depend on first meeting water system reliability targets.
