A new study published on arXiv explores the hidden costs of battery degradation in home energy management systems (HEMS) that solely optimize for energy costs. Researchers used a mixed-integer linear programming model with data from the REFIT dataset to analyze the sensitivity of degradation costs across various battery and photovoltaic (PV) sizes. The findings indicate that degradation costs can significantly exceed energy cost savings, by up to 1,060% in some scenarios, highlighting the need for degradation-aware control formulations in HEMS.

Renewable energy sources like solar and wind, when paired with battery storage, can now provide reliable, 24/7 electricity at costs competitive with or even lower than fossil fuels. This shift challenges the long-held assumption that fossil fuels are inherently more reliable. The International Renewable Energy Agency (IRENA) projects that fossil fuels will constitute only 20% of the global electricity mix by 2050, down from 70% currently. AI
