Whatever they call them, microgrids, local grids, or even auxiliary grids, the right word to use is decentralized. A decentralized grid is typically a small energy grid that allows to power up a community, that is independent of a large, central utility. Blockchain empowers residents of the community to monitor energy consumption online, to switch between various sources and prices. A decentralized grid is independent of the national or a regional energy provider, but may be connected to it, typically to sell the excess energy back (net metering).
Significant progress in decentralized grids has been in the US, England, Germany, Singapore. Australia and Thailand follow. Many more countries are looking into their examples. There are at least three major companies with expertise and experience, ready to scale their projects to overseas markets.
P2p trading is what most projects are for now. Sold to the fittest bidder. However, the objects of the trade between peers vary, from excess solar power generated by one household in the project to UN issued climate credits between enterprises.
One may assume, the next step to be total opening of all opportunities that tokenization brings, that may be fox example, crowdfunding to shift to solar power in a particular area as a part of strategic environmental development plan, in response to climate change, or tokenization of assets in solar corp, such as shares in particular projects, advanced monitoring system that reward users to using more clean energy etc.
The tokenization of solar corporate assets may one day result in an advanced market of such securities.
