Many people put solar panels on the roofs of their homes. When they produce more energy than they consume, they can sell the excess back to the grid for a small profit. This is called net-metering. However, many power companies do not allow net-metering, or allow people to sell back at very low rates. Our mobile app allows communities to make better use of their surplus energy by allowing peer-to-peer energy transactions to happen at the local scale, using microgrids and blockchain technology.

What it does

Instead of going through government and corporate-owned power grids, our microgrid system allows communities to make more effective use of excess solar energy by transferring electricity directly from local provider to local consumer. You can buy and sell energy within your neighborhood using our mobile app, at fairer prices than those provided by your power company. The app allows you to set the price at which you are willing to sell or buy energy when you have a surplus or a deficit, and keep track of how much money you make or save by using the app.

How we built it

The app was built using native-react. Simulated data was used in place of actual data from solar panels and power grids. The informational website was built using's website builder tool.

Challenges we ran into's website builder tool was buggy and unreliable. It allowed for quick development, but in the end, resulted in us being unable to edit the website further without re-creating it from scratch.

Accomplishments that we're proud of

Creating a sleek, user-friendly design.

What we learned

We learned what blockchain is.

What's next for Currentcy

For wide-scale implementation, the next step is to organize actual community microgrids, to get the necessary infrastructure for our system out into the world.
