In the last five years, the energy sector has been shaken by many “disruptive” technologies: distributed renewable energy, smart grids, energy storage, and fuel cells.

Which one is the right one to pay attention to? Which one will truly cause the most disruption?

It seems the answer may very well be blockchain technology. Blockchain has hundreds of use cases and has the potential to disrupt the energy sector among many others.

If you’re very new to blockchain technology and looking to know more about it, I suggest you read this ultimate guide by Cryptomaniaks.

Blockchain will disrupt the energy sector in five overarching ways. Let’s take a look.

1. Blockchain-based microgrids empower individual consumers

Microgrids are aptly named. Unlike a typical power grid where electricity is distributed from a central authority to thousands on thousands of customers — a microgrid can be as small as one home, powered by solar panels, distributing and selling its oversupply of energy to other homes in the area.

One of the most obvious differences with regular power grids is pointed out in an article from Hackernoon: “This interconnectedness means that when part of the grid needs to be repaired, everyone is affected.

By contrast, the author points out that “a microgrid can disconnect from the traditional grid and operate autonomously.

A community may choose to use a microgrid for myriad reasons:

  1. Backup in case of emergencies;
  2. Cutting costs
  3. Connecting to a local resource that is too small or unreliable for traditional grid use
  4. Becoming “energy independent”
  5. Become more environmentally friendly

Blockchain will empower these individual consumers and producers.

Each household that can generate and store electricity can use “smart contracts.”

Smart contracts, to put it simply, are made to digitally facilitate, verify, or enforce the negotiation or performance of a contract. You don’t need a third party, digital or otherwise, to perform credible transactions — all you need is a smart contract.

These smart contracts are automated. In the energy world, they can connect, disconnect, reroute electricity, and make peer-to-peer transactions with other households a real possibility.

Using microgrids and smart contracts, these households will become “prosumers.

2. Blockchain will make P2P energy trading possible.

How can these prosumers make sure that they are buying, selling, and trading energy at fair market rates? Through peer-to-peer (P2P) energy trading.

P2P energy trading is just as the name states: trading energy from one person or entity (producer) to another person or entity (consumer), without the use of a middleman.

The rise in photovoltaic (PV) solar panels in the last 50 years combined with solar energy costs becoming cheaper in the past 10 years have opened the way for everyday consumers to become energy producers themselves.

The most common scenario is that their excess energy is sent back to the public utility. The public utility then credits the homeowner.


With blockchain, we once again see the power of smart contracts. Specially built smart contracts running on a blockchaincan provide a secure, transparent and decentralized ledger of all energy production, consumption data, and transactions thereof.

These specific smart contracts will not only be able to track, distribute, and adjust energy consumption — while recording all the data onto a transparent, secure ledger. They will also provide an automated marketplace where these prosumers can bid amongst each other to purchase renewable energy.

Example case study: the Brooklyn MicroGrid

Let’s examine a real-world use case.

Brooklyn MicroGrid is a blockchain-based P2P energy trading platform run by Transactive Grid in Brooklyn, New York. This setup is a collaboration of LO3 Energy, Consensys, Siemens and Centrica.

Brooklyn microgrid is disrupting the energy sector in the Gowanus and Park Slope communities. They’ve finished a three-month trial run of P2P energy trading between community members.

A Sciencedirect article sums it up nicely by stating that “prosumers can sell their energy surplus directly to their neighbours by use of Ethereum-based smart contracts and PBFT consensus, implemented by Tendermint. The first trial included 5 prosumers and 5 neighbouring consumers and resulted in the first-ever energy transaction recorded in blockchains worldwide.” A small but resounding success.

This microgrid is run on Ethereum, not only for smart contracts but also for payment. Residents use the Ethereum blockchain to run their power as well as to pay for it.

3. Blockchain will empower the electric vehicle boom

Tesla may be the biggest name in electric vehicles, but it’s certainly not the only one.

Nearly every automaker on the planet, from Chevy to Nissan to Toyota and back again, is building EVs.

Electric vehicles will take over. Mark my words. Electric vehicles are fast, fun, and fuel efficient.

Bloomberg New Energy Finance posted a forecast in its Electric Vehicle Outlook 2018. They estimated global EV sales to surge from 1.1 million in 2017 to 11 million by 2025. That’s a gigantic increase. Moreover, by 2040, more than half of new car sales and fully one-third of the global fleet will be electric.

Those figures show one thing: an entirely new class of customers previously locked to the petroleum/gas industry.

But how will this growth affect utilities and grid operators? After all, this new class is both a new source of demand and electricity sales and a major challenge. How will companies handle millions of EVs simultaneously plugging into 100+ kW high-capacity charges? Will they overload the power grid? Or worse — will they face a “fuel shortage” like the ones that used to hit gas cars?

During my travels around the world — 1 year on 1 Bitcoin — I encountered a handful of innovators working to address these issues.

I recently found a webinar by two such innovators with the title ”Blockchain for EV charging: How data platforms make it happen.”
They pointed out that the blockchain will take the burden off utility companies. Blockchain, especially smart contracts related to payments for prosumers, will create “a win-win scenario where economic incentives are aligned.”

Here is what this means:

  1. Homeowners get a faster return on their investment (of buying/installing a charging post) by also allowing their charging post to sell electricity to other EV owners
  2. EV owners get more charging locations to choose from, reducing EV “range anxiety” — just like petrol drivers can have an empty tank — EV drivers can too. But EV drivers currently have more anxiety because finding an EV charging station is difficult! However, with microgrids and blockchain — more EV charging posts would pop up. Maybe even one in every neighbourhood!
  3. Utility companies get a new, digital market in which they offer products and/or services.
  4. The shortening of settlement periods from 20 days to hours and the changing of settlement cycles from monthly to daily.

Blockchain will disrupt the energy sector by allowing individuals on microgrids to offer their electricity not only to other homeowners — but also to passing motorists.

Think of it like “AirBnB for gas stations.” EV owners can get on their smartphones and find a ‘gas station’ that is located simply in someone’s driveway — or at the curb of a housing subdivision running its own microgrid — and charge up! Now that’s disruption.

4. Blockchain makes smart grids possible

Microgrids are all well and good, but what about typical large grids? Turning these into “smart grids” is in the realm of possibility for blockchain technology.

The vision of Smart Grids is to enable and manage smart appliances, ventilation and air conditioning (HVAC) units, automated control of heating, and the EV’s previously mentioned.

The smart grid is a grid allowing interconnected smart devices to coordinate and react to price, renewable availability or grid stability signals. These smart grids would adjust accordingly, fluctuating their power consumption according to price and other factors.

Such smart grids are superior to traditional centralized approaches because, when it comes to managing many smart devices, traditional approaches become inefficient when scaled to large numbers of devices that produce high volumes of data at high frequencies.

Blockchain applications would come to the rescue. Blockchain would enable IoT (internet of things) platforms to have interoperability in IoT applications. Blockchains, by their very nature, would provide a solution to control and manage increasingly decentralized complex energy systems.

Let’s face it, Integrating microgrid renewables, flexibility services, and prosumers in the energy market is a demanding task. Blockchains would reduce transmission losses and defer expensive network upgrades.

Energy Executives are already considering blockchain.

An article from Sciencedirect tells us that “a survey of the German Energy Agency on the views of energy decision-makers shows that near 20% believe that blockchain technology is a game-changer for energy suppliers.

70 executives working in the energy sector participated in this survey. They were from utility companies, energy suppliers, network operators, generators, and aggregators. Even more telling, the majority of these energy executives said they have already undertaken initiatives for blockchain innovation.

The article goes on: “according to senior consultancy and commercial reports by Deloitte and PWC, blockchains have the potential of radically disrupting energy-related products and commodities.

5. Blockchain will enable variable electricity rates

The most significant disruptions in any sector happen when the price of things is affected. Well, I have news: Blockchain technology will disrupt the energy sector through price too.

At the moment, for the majority of people, electricity rates are set by centralized utility companies. But with blockchain technology, rates will no longer be fixed by these centralized authorities. Only the market (supply and demand) will determine the price.

The same article in Sciencedirect points out that “electricity tariffs will begin to behave like tradable commodities that respond to demand and supply signals in a fully functioning distributed electricity market.

Such a distributed market model will empower prosumers and another consumer to select their electricity from an array of choices. Consumers will be able to get on their phones and scroll through listings of all sorts.

We will soon consume electricity in a whole new way

Blockchain solutions will enable smart charging arrangements and sharing of resources in ways that will open our economy in new ways.

Airbnb has already opened up personal homes to the sharing economy. Uber opened up personal cars to the sharing economy. It’s only a matter of a few short years before blockchain opens up our electricity usage to the sharing economy.
