Undersökning av kombinerade lönsamhetsstrategier för ett batterilager

Sammanfattning

The increasing electricity production from intermittent energy sources creates both challenges and possibilities in the future energy system. When the controllability in the production of electricity deteriorates, the flexibility of the electricity consumption must increase for the energy system to work. The study examines the possibilities for the profitability strategies load smoothing, peak shaving, participation on the flexibility market and its combinations to reduce the electricity bill for Vasakronan’s office building at Sperlingens Backe 47 in Stockholm using a nickel-metal hydride (NiMH) battery storage. The results indicated participation on the flexibilitymarket to be the most profitable strategy although none of the strategies nor their combinations managed to reduce the electricity bill of the office building. For an installation of a NiMH battery in the office building to become profitable, the price of NiMH batteries must decrease by approximately 80 %.
