Does Peak Load Occur at the Same Time as High Electricity Prices? : A Case Study of Sports Facilities

In this study, a simple framework was developed that can help identify and quantify peak load at sports facilities called Rocklunda Fastigheter AB. By analysing the electricity demand profiles and electricity prices from the Nord pool market, we characterize the equipment contributing most to a particular peak load. In addition, we quantified peak loads that occur during high electricity prices. This framework is beneficial in choosing an appropriate demand-side management strategy for reducing peak loads and electricity costs for both academic and public end-users. Finally, a load-shifting strategy based on Mixed Integer Linear Programming (MILP) was developed to minimize the total annual electricity cost. This approach suggests shifting the electricity demand to the early morning hours while reducing it in the evening when the electricity prices are higher. Finally, a cost-benefit analysis revealed the potential for savings of up to 9.5% when implementing a flexibility factor of 30%.
