Do Battery Energy Storage Systems (BESS) avoid more carbon than they create? It's the question at the heart of responsible energy storage, and one Harmony Energy takes seriously.   Our latest article dives into the carbon footprint and carbon displacement of our BESS assets, discussing:   ⚡ Why BESS matter: BESS are the backbone of a renewable energy future. They store excess power when it’s abundant and release it when it’s needed most, smoothing out the natural variability of renewables and ensuring a reliable, clean electricity supply.   🌱 Our 2025 carbon footprint: Our total group carbon footprint was 55,570 tCO₂e in 2025. Of that, 99.86% came from Scope 3 activities in our upstream and downstream supply chain such as construction, procurement of batteries and other equipment and business travel.   🔋 Carbon displacement in action: Over their typical 35-year lifetime, a single 99MW BESS asset delivers a net emissions saving of approximately -186,690 tCO₂e, achieving a carbon payback period of just four years. For the ten UK BESS assets Harmony managed in 2025, the renewable energy stored and exported was 129,106 MWh and carbon avoided was 36,831 tCO₂e.   🍃 What’s next? The future of BESS lies in innovation and collaboration. From circular design principles and second-life batteries to cleaner manufacturing and smarter dispatch algorithms, Harmony is committed to lowering the carbon impact of BESS at every stage of their lifecycle.   The verdict is clear: while BESS have an initial carbon footprint, they avoid more emissions than they create, making them essential tools for a clean, reliable and resilient energy system.   Read the full story on our website and discover how we’re powering a sustainable future: https://lnkd.in/ehKHNV9U   #Sustainability #EnergyStorage #CarbonReduction #RenewableEnergy #BESS
