Current legacy-system-based energy grids are increasingly being upgraded with systems that provide us data from various places in regards to various factors. Smart sensors in electricity transfer and communication platforms are used to create a smart grid, which enables power companies, grid operators and other parties to better bring us the energy we need.

Infusing the smart grid with blockchain systems can bring even more improvements by enabling near-instantaneous micro transactions between machines or people who want to sell excess energy stored in smart batteries or connect the wholesalers of electricity into a more efficient trading network.

Use cases in the energy sector are many and not limited to microgrids in which participants can trade power inside the grid or even to other grids, connecting power producers and consumers into shared systems without intermediaries, financing energy projects, recording and trading sustainability units and using electric cars as mobile batteries supporting the main grid when plugged into the network.
