The economics of battery storage continue to improve as lithium-ion battery costs decline and performance improves. Utility-scale installations can now provide energy storage services at costs competitive with traditional grid infrastructure, particularly when multiple value streams are considered. Battery systems can participate in energy markets, capacity markets, and ancillary service markets simultaneously, maximising their economic value while providing critical grid services.
Vehicle-to-grid technology implementation in urban areas
Vehicle-to-grid technology enables electric vehicles to serve as distributed energy resources, providing electricity back to the grid during peak demand periods or emergencies. This bidirectional charging capability transforms electric vehicles from simple load consumers into valuable grid assets that can provide frequency regulation, voltage support, and emergency backup power. Urban areas with high electric vehicle adoption rates are beginning to realise significant grid benefits from these mobile storage resources.
Fleet operators are finding that vehicle-to-grid services can provide additional revenue streams that improve the economics of electric vehicle adoption. School bus fleets, delivery vehicles, and ride-sharing services can generate income by providing grid services during periods when vehicles are parked and connected to charging infrastructure. This creates a compelling business case for electrification while providing valuable flexibility resources to grid operators.
Microgrid development for community resilience
Microgrid systems are enhancing community resilience by providing localised energy generation and distribution that can operate independently during grid outages. These systems typically combine renewable generation, energy storage, and intelligent control systems to serve critical facilities like hospitals, emergency services, and community centres. During normal operations, microgrids can reduce energy costs and provide grid services, while during emergencies they ensure continued power supply for essential services.
Community-scale microgrids are enabling greater local control over energy resources and supporting the integration of distributed renewable generation. These systems can incorporate rooftop solar arrays, small wind turbines, and combined heat and power systems to provide comprehensive energy services at the neighbourhood level. The modularity of microgrid designs allows them to be expanded over time as community needs evolve and additional resources become available.
