Grid+ created a computer (called Grid+ Smart agent) with natively integrated hardware and software for the Ethereum protocol, that pays for a customer's electricity usage in real time. Grid+ operates with a two-ERC20 token model. The BOLT token, required to use the Grid+ platform is treated as a stable-coin. It's redeemable by customers for $1 worth of energy from Grid* and backed by USD deposits. The GRID token allows Grid+ customers to purchase electricity from Grid+ at wholesale price.
