Cornwall LEM Residential Electricity Dataset with Solar Production and Battery Storage, 2018-2020

Three categories of data are included in this dataset: Measurement Datasets; Forecast Datasets; Dimension Datasets. The Measurement Datasets include the following: 1) Timeseries Database Table: t_msb1m (resolution 1-min): Sonnen data recorded from the 'MySonnenBatterie' (MSB) portal, including a range of Energy records and State of Charge data. 2) Timeseries Database Table: t_ims1m (resolution 1-min): Independent Monitoring System (IMS), consisting of Energy, Power, Grid Voltage, Grid Frequency & Grid Power. 3) Timeseries Database Table: t_ims1s (resolution 1-sec): Independent Monitoring System (IMS), consisting of Power (PV, Grid, BESS) and Grid Frequency. The Forecast Datasets include the following: 1) Timeseries Database Table: t_prodconsforecasts (resolution 1-hr): Production & Consumption Forecasts from Sonnen, via Sonnen VPP. 2) Timeseries Database Table: t_weatherforecasts (resolution 1-hr): Weather Forecasts from external provider, via the MSB portal, including precipitation, solar irradiance and sunshine hours, available at Post Code District level. The Dimension Datasets include the following: 1) Database Table: t_sites: Site List, linking the persistent site ID, to Battery Energy Storage System (BESS) type, BESS power/energy capacities, photovoltaic (PV) capacity and major load type. 2) Additional MetaData: including the following: a) Original Web Questionnaire; completed by respondents from the original recruitment exercise - results available for 66 sites; b) Desktop & Site Surveys, Design & System Costs; completed by SunGift (Installation Contractor) on behalf of Sonnen (BESS Vendor) - results available for 71 sites; c) Summary of EPC data; data retrieved from the EPC register[1] completed by TLC - results available for 75 sites.
