Aggregated Hourly Load and Generation Profiles for the Kurzeme Region, Latvia, 2025

This dataset provides aggregated hourly electrical load and generation profiles for the Kurzeme region of Latvia for the year 2025. The Kurzeme region is a western region of Latvia located along the Baltic Sea coast, characterised by a mixed urban, rural and coastal energy demand profile and increasing integration of renewable energy generation. The dataset is based on measurements from 17 transformer substations and contains only summed regional values; individual substation-level time series are not included.

The published time series includes active and reactive power components for both generation and load. The dataset contains 8760 hourly records covering the period from 1 January 2025 to 31 December 2025. The following variables are included: date, time, active generation, reactive generation, active load, and reactive load.

The aggregation covers transformer substations with a total installed transformer capacity of 553.9 MVA. The total installed generation capacity connected to the analysed substations is approximately 189.9 MW. This includes 108.6 MW of solar photovoltaic generation, 46.7 MW of wind generation, 25.3 MW of cogeneration, 3.8 MW of hydropower, and 5.4 MW of battery energy storage systems. 

The dataset can be used for regional energy system analysis, distribution-level load and generation profile assessment, energy community and flexibility studies, scenario development.
