PV–GES techno-economic datasets for flat-terrain and terrain-leveraged configurations in Spain

This dataset supports the manuscript “Market-coupled techno-economic assessment of photovoltaic–gravity energy storage under solar price cannibalization in Spain”, submitted to Journal of Energy Storage. The record includes two Excel workbooks and one README file. The first workbook contains the processed data and simulation outputs for flat-terrain PV–GES configurations, where the useful storage head is provided entirely by the tower height. The second workbook contains the processed data and simulation outputs for terrain-leveraged PV–GES configurations, where the useful storage head combines built tower height and natural terrain elevation. The datasets include OMIE day-ahead electricity price scenarios, PV production profiles, GES design parameters, height-dependent loading/unloading speed assumptions, CAPEX and OPEX inputs, delivered energy, stored energy, LCOD, LCOS, profitability indicators, minimum viable PV size calculations, scalability analysis and sensitivity analysis.
