We are pleased to announce that the Climate and energy related variables from the Pan-European Climate Database derived from reanalysis and climate projections dataset (PECDv4.1) produced by the Copernicus Climate Change Service (C3S) in collaboration with ENTSO-E (European Network of Transmission System Operators for Electricity) has been published in the new Climate Data Store Beta (CDS-Beta): https://doi.org/10.24381/cds.f323c5ec
Since 2022, ECMWF has engaged in active collaboration with ENTSO-E to provide support in the preparation of the Pan-European Climate Database (PECD). The PECD is used by ENTSO-E for the purpose of conducting, among others, resource adequacy assessments (10.1088/1748-9326/aca1d3). These assessments are designed to evaluate, among other aspects, the tail of distribution events, which may result in load shedding, defined as the inability of the electricity system to supply all consumers.
The PECD has historically been developed and maintained by ENTSO-E, with previous versions based on climate data from the past. Since the signing of the cooperation agreement, the role of C3S has been to construct the new version 4 of the PECD, which for the first time allows to investigate the impact of climate change on the power system.
The coproduction of the PECD has been planned in a rolling manner. This approach allows the production of the PECD in a reasonable timeframe aligned with the publication of the annual resource adequacy assessments. Furthermore, it permits ENTSO-E to consult and provide feedback obtained from the different national Transmission System Operators (TSOs) on methods used.
While the PECDv4.2 will be better able to represent the inherent uncertainty of climate projections (by including a greater number of climate models and emission scenarios), the first consolidated version, PECDv4.1, is now available from the Climate Data Store.
Further details are available from the dataset catalogue entry in the Climate Data Store: https://doi.org/10.24381/cds.f323c5ec
