The document discusses Power Ledger, a blockchain-enabled peer-to-peer energy trading platform. It describes how Power Ledger works, allowing consumers to trade electricity locally through a distributed ledger in a secure and transparent way. This helps encourage renewable energy adoption, reduces costs for consumers, and preserves the value of existing grid infrastructure. The blockchain ensures fast, low-cost settlements of transactions without a centralized authority. Microgrids and virtual power plants are also discussed as applications of this local energy trading.

10. ❖ Consumer-focused P2P trading platform that settles trades across
the distribution network at predetermined intervals.
❖ Encourage efficient PV up-take, reduce consumers’ power bills and
reduce emissions.
❖ Reduced load defection preserves the value of network assets.
❖ Trading platform provides product development and customer
service opportunities.

12. What is the blockchain
- A database (ledger) that no one is in control of but
is very secure
- It can be used to process transactions, act as a
hallmark or track provenance
- Information in the ledger is held in nodes
(computers) and to change an entry in the ledger,
majority agreement (consensus) of the nodes is
required
- Uses cryptography

13. ❖ Fast, cheap, secure, transparent settlement of multi-party
transactions.
❖ Formation of dynamic trading ecosystems.
❖ Development of autonomous, secure and transparent
distributed transactive markets with low-cost and virtually
instantaneous market reconciliation and settlement.
❖ Trading arrangements between any number of
counterparties where each counterparty is able to trust the
trading environment is free from the interference or
interpretation of any other counterparty.

15. Traditional vs blockchain databases

17. • A microgrid is a localised grouping of distributed electricity sources, loads
and storage mechanisms that can operate both as part of the central grid or
independently as an island
• A microgrid can be powered by distributed generators, batteries, and/or
renewable resources like solar panels, wind, diesel etc. Depending on how
it’s fueled and how its requirements are managed, a microgrid might run
indefinitely

18. • It is a locally
controlled
system
• it can function
both connected
to the traditional
grid (megagrid)
or as an
electrical island

25. • metering and revenue collection for utility services,
• monetisation of energy capacity, storage and ancillary service
provision,
• embedded network management,
• settlement of transactions relating to the selling of energy and
charging and use of electric vehicles.
• related financial payments and credit systems for energy networks
and energy related applications

27. •Secure interface for consumers to buy and sell energy. Supported by existing banking infrastructure and
transaction products. Supports real-time payment of retailer, network and other charges.
Transaction Layer
•Smart trading engine that matches demand with available generation in each discrete trading period. Ties
a physical energy transaction with a financial transaction within each trading period. Supports the
allocation of value to the owners/investors in distributed system assets.
Trading Layer
•Provides the trust in the system. Provides an immutable record of all generation, consumption and trade.
Auditable, immutable and permanent. Provides data to the market on off-market transaction (net trading
position). Supports reporting and data management obligations.
