Beyond Peer-to-Peer Energy Transactions with Blockchain

Blockchain technology will play a key role in the transactive grid of the future. A blockchain is an immutable, distributed, shared ledger that makes it possible for energy and energy-related financial transactions to be securely recorded and settled. Not all blockchains are created equal, however. A blockchain that would be able to support the complex services and interactions fundamental to managing energy grids and markets has very specific requirements related to its consensus and storage models, and services for identity, access control, and contracts.

Before we can define what those requirements are, it’s important to first understand the use cases and applications that the energy blockchain would support.  A report from late 2016 by the German agency, dena, provides a very good overview of several key use cases.  They conducted a survey of German energy executives which provides great insight into how blockchain can and is being used by the energy industry.

This excerpt from the introduction of the report highlights some of the key findings you'll find in the report:
More than half of the 70 respondents have already experimented with Blockchain or plans to do so. 21 percent consider Blockchain a game changer for the energy supply industry. 60 percent of the respondents believe that a further dissemination of the Blockchain is likely, and 14 percent expect niche applications. The survey also covered potential use cases: Around half of the use cases mentioned by respondents are related to process optimization, including billing, sales and marketing, automation, metering and data transfer, mobility, communication, and grid management. The second half is linked to public and private trading platforms, in particular peer-to-peer trade, and decentralized energy generation.
Another great discussion can be found in a report produced by PwC around the same time titled Blockchain – an opportunity for energy producers and consumers?.  As a brief introduction, this excerpt summarizes some of their key points:
Blockchain technology shows a lot of promise. Other than being used to execute energy supply transactions, it could also provide the basis for metering, billing and clearing processes. Other possible areas of application are in the documentation of ownership, the state of assets (asset management), guarantees of origin, emission allowances and renewable energy certificates.
This comprehensive report provides detailed explanations for how blockchains work and how blockchain can be applied to various use cases.  PwC also discusses some of the features certain blockchains have and why they are especially important for an energy blockchain.

These are two good resources for a comprehensive overview of energy blockchain use cases.  In a future post, I'll go into detail to describe the key characteristics of what I see as the most important use cases for the energy industry, and particularly for how distributed energy resources can participate.  I'm thinking beyond the sphere of peer-to-peer energy transactions, which are really popular right now as a first use case for an energy blockchain.  What do you see as the most beneficial or lucrative use cases of blockchain technology to the energy industry?

What is Power Ledger's play in the energy blockchain space?

Power Ledger is building an energy blockchain platform to connect all of the players of the energy ecosystem together - prosumers, consumers, market operators, utilities, etc. They want to “enable interoperability between diverse market management/pricing mechanisms and units of electricity (kWh) by way of pre-purchased tokens.”  Here's my take on what they are up to. Business Model / Offering Power Ledger's offering is a blockchain-based platform that facilitates participation by “all” parties in the energy ecosystem, called the Platform. Utilities and other 3rd-party businesses that will facilitate trading on the platform are called Application Hosts. Examples of Application Hosts include energy retailers, property managers, and EV-charging businesses. Participants are the consumers or non-Application Hosts and the users. There will or can be an unlimited number of applications that run on the Power Ledger Platform. The first, and only one currently available, is FuseBox...

Intro Topic: Distributed Ledgers vs. Blockchains

What's the difference between distributed ledgers and blockchains?  "Bits on Blocks" published a brief introduction on this topic earlier this year.  The key takeaways from that article are pretty high level but still helpful when thinking about this.  For example, this: If you want to include all the initiatives going on, use the term “distributed ledgers”. If you mean blockchains, where unrelated transactions are bundled into blocks, which are chained together using hashes and (in most cases) broadcast to all participating entities for batch processing, use “blockchains”. If you like acronyms, use “DLT”: Distributed Ledger Technology Colin Pratt also provided some very interesting detail on this concept along with a discussion on taxonomy in general in his blog post "Thoughts on the Taxonomy of Blockchains & Distributed Ledger Technologies." Colin highlights that Bitcoin's blockchain has some key features that really illustrate what makes it dif...

Can Grid+ actually disrupt energy markets in the US?

Overview Grid+ spun out of, and is owned by, New York blockchain development house ConsenSys.  ConsenSys, which uses blockchain technology to create applications in many different fields, identified the opportunity to create a solution for the energy space.  The goals of Grid+ are to demonstrate production-ready blockchain-based energy solutions at scale in competitive commercial environments in order to enable the transactive grid of the future and prove the advantages of Ethereum over incumbent technologies. To get started, Grid+’s strategy is to become an energy retailer in Texas and to win customers by offering energy savings compared to the incumbents.  They will use their own hardware solution for energy management combined with efficiencies from trading using Ethereum.  Their hardware solution is called the Intelligent Agent.  It is a computer that basically pays for the customer’s electricity use in real time by reading from the smart meter. The Inte...
