GreenSync

Inspiration

Portugal has immense solar potential but faces regulatory bottlenecks. Producers have surplus energy they can't easily sell, while corporations need Net-Zero solutions but are stuck with generic carbon credits. We realized the physical grid is the barrier, but the financial market is the bridge. GreenSync was born to move environmental value without moving electrons, democratizing energy profits for every rooftop.

What it does

GreenSync is a marketplace using a Virtual PPA (VPPA) model to decouple energy flow from financial value. Instead of manual trading, our Automated Matching Engine pairs corporate "Green Budgets" with local producers via fixed-price contracts. This ensures price stability for buyers and significantly higher returns for sellers compared to standard grid tariffs.

How we built it

We focused on three technical pillars:

Data Layer: API connectors read real-time injection data ($$E_{injected}$$) from smart meters.

Matching Engine: An algorithm that calculates an optimal fixed price ($$P_{fixed}$$) where: $$P_{grid} < P_{fixed} < P_{retail}$$ This creates a secure arbitrage, beating both grid tariffs and retail market peaks.

Trust Layer: A blockchain ledger that mints Local Impact Certificates, ensuring every $$MWh$$ is unique and audit-ready for ESG reporting.
