The way in which you decide the price for electricity is on it’s way to change in Sweden and to decrease the amount you pay for electricity you can use something called Peak Shaving. Peak Shaving is a method to reduce the overall power kWh peaks that an average power consumer uses monthly in order to reduce the price of the electricity bill. Furthermore, Peak shaving can be a method to resolve the lack of power in bigger cities. This is done by installing battery packs which store power when the power consumption is low. When power peaks occur, the power in the battery pack is used to help the grid and lower the peaks in the amount of power bought. With this method, you can reduce the power peaks you draw from the grid which leads to a lower monthly fee for the consumers. In this report we investigated if Peak Shaving was profitable, more specifically for farmers and households with already installed solar panels. A model was designed to determine whether or not it is beneficial for the farmer to install battery packs for Peak Shaving depending on the power peaks they had per month. Data was received from two different farmers in Sweden containing energy bought, sold, produced(solar) and consumed. When comparing this to the price of power peaks per month as well as the price of the battery packs needed to contain the power to Peak Shave, the conclusion was made that Peak Shaving is not profitable with the current prices for batteries and their lifespan. However the price is on it’s way down. This could lead to Peak Shaving becoming a solution to save money for the customer but also to reduce the stress on the grid when Sweden transitions to fully renewable power.
