An uninterruptible power supply (UPS) includes an energy routing circuit coupled to a grid and an energy storage device and configured to selectively provide energy to a first load from the grid and the energy storage device based on a state of the grid. The UPS further includes a controller configured to control the energy routing circuit and to implement a first UPS node configured to establish and execute a first smart contract for energy exchange with a first consumer node associated with the first load and at least one second smart contract for energy exchange with at least one of a grid node associated with the grid and a second consumer node associated with a second load coupled to the grid via a second UPS.
