How are prices set and trades matched in this P2P energy market?

By a repeated auction: buyers and sellers submit bids, and the market clears at a price that balances supply and demand, settled periodically (e.g. daily).

Instead of a fixed tariff from a distributor, pricing is auction-based. Sellers (prosumers with surplus) and buyers submit bids to a shared order board; the market clears at a price where offered supply meets demand, and this repeats on a regular cycle. Auctioning does two jobs at once: it discovers a fair market price transparently, and it incentivizes production — clean generation is rewarded when it is scarce. Settlement happens periodically (for example once a day) rather than continuously, which stabilises prices and lets the system reconcile predicted against actual flows each cycle.
