The energy storage industry is full of technical terms that can sometimes be difficult to understand. This glossary provides clear and concise explanations of the most important concepts, technologies, and applications in energy storage. Whether you are new to the field or an experienced professional, you will find this resource helpful for understanding the terminology that drives the industry.
→ ESS (Energy Storage System) – A complete system that stores energy and releases it when needed.
→ BESS (Battery Energy Storage System) – An ESS that specifically uses batteries for energy storage.
→ PCS (Power Conversion System) – Converts energy between AC and DC to integrate storage with the grid.
→ EMS (Energy Management System) – Controls and optimizes the performance of the storage system.
→ BMS (Battery Management System) – Ensures the safety, efficiency, and lifespan of batteries.
→ LFP Battery (Lithium Iron Phosphate) – A safe and long-lasting lithium-ion battery chemistry.
→ NMC Battery (Nickel Manganese Cobalt) – Known for high energy density and performance.
→ Depth of Discharge (DoD) – The percentage of battery capacity that has been used.
→ State of Charge (SoC) – The remaining available energy in a battery.
→ Cycle Life – The number of complete charge and discharge cycles a battery can handle.
→ Peak Shaving – Reducing energy use during periods of high demand.
→ Frequency Regulation – Stabilizing the grid by balancing supply and demand.
→ Microgrid – A local energy system that can operate independently from the main grid.
→ Virtual Power Plant (VPP) – A network of distributed energy resources managed as one system.
→ Backup Power – Providing electricity during outages or grid failures.
→ LCOS (Levelized Cost of Storage) – The total cost of building and operating a storage system per unit of energy stored.
→ CAPEX & OPEX – Capital expenditure vs. operational expenditure.
→ Grid Parity – When renewable energy costs match or beat conventional power.
→ Energy Arbitrage – Buying electricity when it’s cheap and selling it when prices are high.
→ Power Purchase Agreement (PPA) – A contract for the sale of electricity.
→ Smart Grid – A modernized grid using digital technology to improve reliability and efficiency.
→ Carbon Neutrality – Achieving net zero carbon emissions.
→ Long-duration Energy Storage (LDES) – Storage technologies that can operate for many hours or days.
→ Second-life Batteries – Reusing EV batteries in stationary storage applications.
→ Hydrogen Storage – Using hydrogen as an energy carrier for long-term storage.
