The client
An energy platform operator connecting generation sources and consumption points.
The challenge
The operator wanted an indisputable record of energy produced and consumed, and a way to settle usage that is billed after the fact. Pre-paid token models did not fit, because consumers pay only after they have used the power.
What we built
We turned electricity itself into tokens. Smart meters at generation sources and consumption points record readings on-chain, and tokens are minted for every watt-hour produced and consumed. A two-token model — ENERGY for production and CONSUMPTION for usage — lets the platform compute the bill and then burn both tokens 1:1 at settlement. The contracts were tested and audited for security, are portable across EVM chains, and every transaction and event can be checked on the Hedera explorer.
Workflow
- Smart meters and consumption points registered in the contract via an on-chain transaction
- Meter readings signed and stored on-chain at regular intervals
- ENERGY tokens (ERC-1155) minted per reading to the generator’s wallet; metadata carries the reading and meter ID
- CONSUMPTION tokens minted at each consumption point for energy used
- Cost computed from usage and current pricing; consumer pays in fiat or crypto
- On settlement, CONSUMPTION and ENERGY tokens burned 1:1 for that consumption point
- Dashboards for active meters, energy generated and consumed, balances, burns and unsettled amounts
How success is measured
The platform reports active meters, cumulative energy generated and consumed, token balances, tokens burned and unsettled amounts at every consumption point — all verifiable on Hashscan.
