# Use Cases
With the ability to tailor payment flows to any smart energy or DER use case or geography, the OpenVPP tech stack enables first-of-its-kind applications which are almost unlimited in their potential.\
\
Our initial high priority use cases:
1. **Real‑Time Settlements**
The OVPP Payments Network enables instant settlement for solar and battery customers: the moment renewable generation is exported, USDC is credited to the customer’s utility‑linked wallet and could begin accruing 4 % APY or real-time APYs offered by the stablecoin issuer.
2. **Energy Procurement & Demand Response**
Utilities can purchase capacity from power plants or connected devices seamlessly with participants in demand‑response or virtual‑power‑plant programs receiving token rewards the instant their connected devices reduce load during weather‑driven grid events. Power plants receive compensation on-chain, in real time, instead of accounting on paper with payments often months later.
3. **EV Payments Everywhere**
A driver simply scans the QR code on any participating public charger; the session starts automatically and the cost posts straight to the user’s utility bill, eliminating the need for multiple charging apps and enabling EV charging in apartment buildings which otherwise wouldn’t be willing to deal with the complexity of billing tenants.
4. **Electric‑Bill Pre‑Payment**
Utilities can issue kWh-denominated tokens, each redeemable for one kilowatt‑hour. Customers pre‑purchase energy at a small discount (e.g., 4%), locking in today’s price ahead of rising rates, while the utility secures immediate cash flow.
5. **Peer‑to‑Peer Renewable Energy Trading**
Apartment dwellers, or even large corporations, can buy solar output from homeowners or utility‑scale plants. Buyers pay a slight premium for verified green power; sellers receive the renewable‑energy credits directly.
6. **On‑Chain Energy Attributes**
A decentralized validation registry records every renewable‑energy or carbon‑offset credit, supporting a 24/7 marketplace with an immutable audit trail of generation, transfer, and retirement.
7. **Cross-Border Transactions**
Cross-border energy trades between Independent Service Operators (ISOs) and transnational grid operators can use stablecoins as a settlement currency instead of foreign exchange-based transactions. Smart contracts can programmatically handle tiered pricing models, late fee adjustments, and prepaid energy credits.
These are initial use cases that have been proposed by our current and prospective partners, but the applications are endless with payment solutions tailorable to almost any energy utility need.
