To reduce the cost for energy, it is possible to either reduce the energy consumption or to shift the energy consumption to times when energy is cheaper. With an increasing share of renewable energy, the latter becomes more and more important. To shift the energy consumption, one of the most important steps is to forecast the water demand. In this repository, we provide a collection of eleven water demand datasets.</p> <h2 class="code-line">Datasets</h2> <h3 class="code-line">Key Information</h3> <ul class="code-line"> <li class="code-line">Number of Datasets: 11</li> <li class="code-line">Granularity: 15 minutes</li> <li class="code-line">Time Range: 2024-01-01 to 2026-01-28 (differs across datasets)</li> <li class="code-line">Number of Records: 47448 - 70161 (differs across datasets)</li> <li class="code-line">Features: 1 (water demand in m³/h)</li> </ul> <h3 class="code-line">Origin</h3> <p class="code-line">The datasets are collected from three different water utilities in Germany. The datasets represent real water demand data that is collected from sensors placed at outflows of reservoirs.
