Battery Storage for Self-Consumption & Demand Shifting

Batteries store electrical energy for later use, transforming what renewables and smart tariffs can deliver. They are central to maximising self-consumption, shifting demand, and providing resilience, and their falling cost is steadily widening the range of buildings where they pay. This lesson covers what batteries do, the dominant lithium-ion chemistry, the key metrics, the uses for buildings, the economics, and sizing.
