Create a Decentralized P2P Energy Trading System

Enable households and producers to trade electricity directly on a blockchain-based marketplace, ensuring transparency, automation, and energy equity.

Why Use Blockchain for Energy Trading?

Centralized electricity grids lack transparency and flexibility, especially for small-scale renewable energy producers. Blockchain enables a decentralized, trustless system where individuals can trade excess energy directly and securely.

Project Objective

Build a smart contract-powered marketplace where users with solar panels or other renewable sources can sell their surplus energy to nearby consumers at fair prices, verified and settled on-chain.

Key Features of the Energy Trading Platform

Smart Energy Contracts

Automate buying and selling based on energy availability, demand, and pricing logic.

Tokenized Energy Units

Represent kilowatt-hours (kWh) as tokens that can be transferred peer-to-peer.

Real-Time Metering Integration

Connect smart meters or IoT sensors to log and verify energy generation and usage.

Transparent Pricing and History

Users can view historical prices, energy flow, and peer transactions for full transparency.

System Architecture Overview

Producers and consumers register on a Web3 platform. Producers log available energy via IoT devices, and consumers place bids through the DApp. Smart contracts handle match-making, pricing, settlement, and recordkeeping. Energy tokens represent transferable energy credits.

Solidity smart contracts for trade matching and settlement
ERC-20 tokens representing energy credits (kWh)
IoT integration for metering via external oracles or sensors
React frontend for user dashboards and live trading
Wallet-based authentication and energy wallet balances

Recommended Tech Stack

Blockchain

Ethereum, Polygon, or EnergyWeb Chain

Smart Contracts

Solidity with token issuance, trade logic, and event logging

Frontend

React.js + Ethers.js for trading interface and metering stats

IoT Integration

MQTT or REST APIs from smart meters; Chainlink for oracle data

Development Roadmap

1. Develop Energy Token Smart Contract

Implement an ERC-20 token that represents kilowatt-hours (kWh) with mint/burn functions.

2. Build Trading Smart Contract

Create a contract to handle listings, bids, trades, and settlement between peers.

3. Connect Smart Meter Data

Use oracles or MQTT APIs to verify energy generated and consumed in real-time.

4. Design Frontend for Buyers and Sellers

Allow users to manage energy balances, place offers, and view trade history in a clean UI.

5. Simulate Grid and Trade Scenarios

Run mock energy trades on testnet to validate pricing models and power flows.
