Abstract

This dataset contains the modelling results of the abovementioned study on the risks and economic costs of cooling water shortage of the UK electricity system. The netCDF files each contain multiple variables cast along the same dimensions of time (daily timestep, 30x 360-day years), and Weather@Home (WAH) climate sample run. Each dataset contains the variables for electricity "demand" in MWh (per day); "unadj"usted electricity spot price (£/MWh); "adj"usted electricity spot price (£/MWh); the electricity price "spike" (£/MWh), which is "adj" minus "unadj"; "cumcost" which is the cumulative cost of the drought-induced price spike (£) found by spike * demand; "unadjcost" which is the cumulative cost of the unadjusted wholesale supply in £; and "adjcost" which is the cumulative cost of the adjusted wholesale supply in £. Five files are included in the dataset: three for each of the climate change scenarios, Baseline (BS), Near Future (NF) and Far Future (FF); two sensitivity runs in the Baseline scenario under high (0.9 quantile) and low (0.1 quantile) renewables production; and two sensitivity runs in the Baseline scenario under high (“HIGH: +25%) and low (“LOW” -25%) fuel price scenarios.
