Stand-alone or micro off-grid systems can be used to electrify remote areas when it is not economically justifiable to connect to the power grid. In Sweden there are several flood gates that are used to regulate the water level in hydropower dams, these dams are not always easily accessible. Furthermore, some flood gates are not electrified making the adjustment of the water level complicated and time consuming. An off-grid solution could be used to electrify the water level adjustment and this report aims to identify one remote dam, owned by the company VB Kraft, that could be electrified by implementing an off-grid solution. The report will also investigate which off-grid solution that is most applicable concerning maintenance demand, technical and economic aspects. Sensors for monitoring the status of the dam will also be identified which are required to preserve dam security. The chosen off-grid solution will be simulated on a yearly basis and the most appropriate size of the components will be specified. The report has been conducted by collecting material from the company, a literature study and by interviews and email conversations. Calculations have been performed by using MATLAB and Excel. The data is based on measurements from the Swedish Meteorological and Hydrological Institute. The result revealed that Lilla Ursen, a remote dam in Dalarnas county, is maneuvered often and therefore this study will investigate electrification of this dam. Out of the four alternatives (small wind, hydro and hydrokinetic power and PV), PV was considered the most suitable in an off-grid system combined with a lead-acid battery. Sensors considered important for dam security are water level and flow monitoring, position indicator for the flood gate, camera monitoring and a temperature sensor. It also important with a logger and transmitter. The battery is protected with a charge controller. A series of sensitivity analysis have been conducted and the result showed a large variation concerning the battery capacity and the modules area and peak power. For Lilla Ursen it is recommended with a PV module of 30 Wp and a lead-acid battery with a capacity of 280 Ah.
