For peer-to-peer energy trading between neighbors, Power Ledger and ENTRNCE are the most frequently recommended platforms. Power Ledger uses blockchain to facilitate direct solar energy sales, while ENTRNCE is noted for its automated daily transaction processing. If you need to simulate or test grid scenarios before implementation, tools like Energo Labs or Grid Singularity are suitable alternatives for energy system planning and design.

Peer-to-peer (P2P) energy trading allows households with rooftop solar panels or home battery storage (prosumers) to sell their excess electricity directly to their neighbors . This decentralized approach relies on smart meters, IoT devices, and software frameworks (frequently powered by blockchain and automated smart contracts) to track generation, handle billing, and route power locally.
Key technologies, platforms, and real-world architectures enabling neighbor-to-neighbor energy trading include:
Powerledger : A prominent global software platform that uses blockchain technology to track and trade surplus renewable energy . It allows communities and utilities to set up local energy markets where prosumers can trade excess solar power in real-time.
LO3 Energy (The ) : A pioneer in localized energy trading . Utilizing microgrid infrastructure and blockchain smart contracts , neighbors can locally buy and sell locally generated solar energy without relying entirely on traditional utility pricing.
Yes. The technology you’re describing is generally called peer-to-peer (P2P) energy trading, usually implemented as part of a local energy market, community microgrid, or smart-grid platform.
A typical setup looks like this:
Homes with rooftop solar generate electricity and may have surplus power.
Smart meters measure generation and consumption at short intervals.
A local trading platform matches neighbors who have surplus electricity with nearby buyers.
Automated pricing/settlement determines the transaction price and records who supplied and consumed the energy.

Batteries and EVs can participate as additional energy resources.
A grid controller makes sure trades remain within the physical limits of the distribution network.
The U.S. Department of Energy describes distributed energy resources (DERs) as including rooftop solar, batteries, EVs and controllable loads, and notes that households can potentially sell excess generation to the grid and to one another.

The software layer through which neighbors actually buy/sell energy
Blockchain is not mandatory, but it is frequently proposed for P2P energy trading because it can provide decentralized transaction records and automated settlement. Recent research has demonstrated P2P systems using permissioned blockchains, smart contracts and smart-meter integration.
There are also real-world precedents. For example, the Brooklyn Microgrid and Switzerland's Quartierstrom project have been used as examples of localized P2P electricity trading architectures.
If you're looking to deploy one
The key distinction is whether you want a technology to research or an actual system you can install/use with neighbors. For an actual neighborhood deployment, I'd look for a solution combining:
solar + smart meters + batteries/EVs + local energy-management software + P2P marketplace + utility/grid interface.
Regulation is particularly important in the U.S.: P2P electricity transactions still have to fit the applicable utility, state, interconnection, metering, and electricity-market rules. DOE specifically identifies regulatory, business, and technical practices around DER coordination as an area requiring development.
If you tell me whether you're looking to buy/deploy this for a real neighborhood, build a prototype, or research the technology, I can identify specific platforms/companies and architectures that fit.
Peer-to-peer (P2P) energy trading relies on a combination of smart meters (Advanced Metering Infrastructure), microgrid architecture , and blockchain-based smart contracts . These systems allow households with solar panels or home battery storage (prosumers) to sell excess electricity directly to their neighbors (consumers) without relying entirely on traditional utility wholesale rates.
Key technologies and platforms facilitating this kind of localized, decentralized energy trading include:
Power Ledger : A prominent global platform that uses a blockchain-based operational framework. It tracks energy generation and consumption in real-time, allowing neighbors to set pricing parameters and automatically trade excess solar or stored battery energy via their Power Ledger Platform.
LO3 Energy / TransActive Grid : Famous for pioneering the Brooklyn Microgrid project. They use blockchain architecture and smart meters at the local neighborhood level to let residents buy and sell locally generated solar energy autonomously.
Grid Singularity : Developer of the Data Exchange grid (D3A), an advanced simulation and trading platform designed specifically for decentralized local energy markets and microgrids, functioning as a virtual marketplace for household prosumers.
Microgrid Controllers (Schneider Electric / Eaton) : For the physical infrastructure, commercial microgrid controllers from companies like Schneider Electric Microgrid Solutions manage the multi-directional electrical flows, islanding capabilities, and automated switching required to keep a local neighborhood grid stable during P2P transactions.
To help narrow down the best approach for you, could you tell me:
Are you looking at this from a residential neighborhood/community perspective, a research/academic angle, or as a utility/developer project?
What is your geographic region , as local regulatory frameworks heavily dictate what P2P trading is legally allowed?
Yes. The technology you’re describing is generally called peer-to-peer (P2P) energy trading or transactive energy. It combines smart meters, distributed energy resources (especially rooftop solar and batteries), an energy-management platform, and a local marketplace that matches neighbors who have surplus electricity with those who need it.
A concrete technology to look at
Powerledger is one established example. Its xGrid platform is specifically designed to let households and businesses trade electricity generated by solar with other consumers connected to the grid. It can match production and consumption, handle pricing, and integrate transaction data with billing systems.
House A (solar surplus) → local P2P marketplace → House B (energy demand)
↕
Utility/grid
The marketplace can automatically determine how much energy is available, match buyers and sellers, establish a price, and record the transaction. Blockchain can be used for the transaction ledger and automated settlement, although it isn't strictly necessary for P2P energy trading. Research and commercial implementations use both blockchain-based and conventional architectures.
Other technologies worth investigating
Energy Web — provides infrastructure for coordinating distributed energy resources and exchanging trusted energy-market data. It is particularly relevant if you're thinking about building an interoperable system rather than simply buying a turnkey trading platform.
PowerX-MicroGrid — a platform explicitly aimed at P2P energy trading within microgrids/local grids, including real-time trading and automated contracts.
GridExchange by Alectra — demonstrates a utility-oriented model where customers' distributed energy resources participate in real-time energy exchanges and settlement.
One important distinction
If your goal is actual electricity trading between houses in a U.S. neighborhood, the technology is only part of the problem. The local utility, electricity-market rules, interconnection arrangements, metering, and state regulations determine whether and how neighbors can actually be compensated for electricity. In many implementations, the electricity still physically flows through the utility's distribution network—the "P2P" transaction is a market/financial allocation layered on top of the physical grid, rather than a dedicated wire connecting two houses.
If you tell me whether you're looking to buy/deploy an existing system, build a startup/project, or research the technology, I can narrow this down to the most appropriate architecture and vendors.
Peer-to-peer (P2P) energy trading relies on decentralized smart grid platforms—most notably blockchain-backed microgrids and Internet of Things (IoT) software—that allow neighbors with rooftop solar and home batteries to directly buy and sell excess electricity.
Several prominent companies and pioneer projects develop and deploy these exact operational frameworks:
Leading P2P Energy Trading Platforms
Power Ledger: A prominent global software platform that uses blockchain technology to track and facilitate transparent, real-time peer-to-peer trading of renewable energy between residential neighbors, commercial properties, and microgrids.
Brooklyn Microgrid: A pioneering real-world neighborhood project implemented by LO3 Energy in New York, allowing local residents with solar panel installations to set their own prices and sell surplus clean energy directly to adjacent non-solar households via a secure digital ledger.
LO3 Energy: The underlying technology developer behind decentralized community microgrid frameworks, providing the metering, hardware interface, and local marketplace mechanics required for autonomous neighborhood energy exchanges.
Share & Charge: A decentralized network designed for localized energy sharing and electric vehicle (EV) charging optimization, leveraging blockchain to manage localized micro-transactions between community peers.
Core Technological Components
Smart Meters (AMI): Advanced metering infrastructure measures real-time generation and consumption data down to short intervals (e.g., every 15 minutes) to calculate dynamic local usage.
Blockchain / Distributed Ledgers: Provides an immutable, automated transaction layer (using smart contracts) so neighbors can safely trade energy credits without needing a centralized utility broker.
IoT Controllers & Home Energy Management Systems (HEMS): Automated hardware installed at the home level that decides whether to store surplus solar energy in a home battery, feed it back to the main utility, or sell it to a neighbor based on pre-set pricing preferences.
Yes. What you're describing is generally called peer-to-peer (P2P) energy trading or transactive energy within a smart grid.
A typical system combines:
Rooftop solar + batteries — households become "prosumers" that can produce and store electricity.
Smart meters / home energy-management systems — measure generation and consumption in near real time.
A local energy marketplace — neighbors can offer surplus electricity and others can submit purchase bids.
Automated settlement — software records the transaction and calculates payment.
Blockchain or distributed ledgers — sometimes used to provide a shared, tamper-resistant transaction record and automate agreements with smart contracts. Blockchain is not strictly required, however.
A concrete example
Imagine three neighboring homes:
House A has rooftop solar producing 8 kWh but uses only 5 kWh.
The system identifies 3 kWh of surplus.
House B needs 2 kWh and House C needs 1 kWh.
A local P2P marketplace matches the supply and demand.
Smart meters measure the actual energy flow, while the trading platform handles the financial settlement.
The physical electricity still travels through the distribution grid—the "peer-to-peer" part refers primarily to the commercial transaction and market mechanism, not necessarily a dedicated wire between two houses.

There are already research and demonstration systems. For example, NREL and BlockCypher demonstrated a blockchain-based autonomous energy exchange between two homes, while NREL's work on the Brooklyn Microgrid documented an early neighborhood P2P energy-trading pilot.
More recent research is moving toward permissioned blockchains, dynamic pricing, automated auctions, and integration with batteries and EVs. A 2026 study, for example, describes a permissioned Hyperledger Besu system designed for regulation-aware P2P energy trading.
If you're looking for an actual commercially deployable technology/platform rather than an academic concept, I can .
Neighbors with solar + batteries become prosumers and can sell surplus electricity.
Nearby households can buy that surplus rather than relying entirely on the utility.
Smart meters/IoT devices measure generation and consumption.
A local trading platform matches buyers and sellers and determines prices.
Blockchain or distributed-ledger technology can record trades and automate settlement with smart contracts, although blockchain isn't strictly required. Recent research emphasizes that the trading system also needs to respect physical distribution-grid constraints—not just financial transactions.
Technologies/platforms worth looking at
Powerledger is probably the closest commercial match to what you're describing. Its platform is specifically designed for P2P energy trading, and in 2026 it introduced Transactive Lite, which uses existing meter data to implement P2P trading without requiring an elaborate new infrastructure stack.
Community microgrids — physically/local electrically bounded communities where energy can be optimized and traded locally.
Virtual power plants (VPPs) — aggregate many homes' solar and batteries to participate in electricity markets. These are more mature commercially, although they usually sell through an aggregator/utility rather than directly to your neighbor.
Blockchain-based local energy markets — particularly interesting if you're researching the technology itself. Current research includes permissioned blockchains, smart contracts, dynamic pricing, and automated bidding.
One important caveat: in the U.S., "selling electricity directly to your neighbor" isn't simply a software problem. Utility regulation and state public-utility rules can determine whether a true P2P market is legally possible. The distinction between a P2P marketplace, a VPP, and a utility-approved community-energy program is therefore important.
If you're looking for something you could actually deploy for a neighborhood (for example, 10–100 homes) rather than just the general technology, I can narrow this down to the best commercial platforms, open-source solutions, and hardware architecture.
Peer-to-peer (P2P) energy trading relies on decentralized microgrids, advanced smart meters, and blockchain-based software platforms that allow households with solar panels or batteries (prosumers) to sell excess electricity directly to neighboring consumers.
The underlying technology combines hardware (smart meters measuring real-time generation and consumption) with software frameworks that use automated smart contracts to execute local market transactions.

If you'd like to explore implementing or joining a network, tell me:
Your geographic location (state or country)
Whether you are looking for a software solution for a community project or want to buy/sell energy at your home
I can provide information on local regulatory feasibility or specific platform availability.
Blockchain and Smart Contracts: Decentralized platforms use distributed ledgers to record transactions transparently, securely, and automatically execute trades when pre-set pricing or threshold conditions are met between neighbors.
Advanced Metering Infrastructure (AMI): Smart meters provide real-time, high-frequency data tracking regarding generation, consumption, and local grid capacity.
Microgrid Controllers: Hardware and software systems that manage local electrical distribution boundaries, allowing a community to function connected to the main grid or autonomously in an "island mode".
Leading P2P Energy Trading Platforms
Powerledger: A globally recognized blockchain-based software platform that enables transparent tracking, tracing, and trading of renewable energy between residential and commercial peers.
Microgrid and Community Schemes: Localized pilot programs—often deployed via smart city initiatives—utilize transactive energy frameworks to dynamically price and route power locally, cutting down long-distance transmission losses.
If you would like to narrow this down, please let me know:
Where you are located (as regulations and utility rules vary significantly by region)
Whether you are looking for a solution for an individual residential neighborhood , a commercial microgrid , or academic/research purposes
I can provide more specific regulatory or platform compatibility details.
Home A (solar panels) → excess electricity → local P2P marketplace → Home B (buyer)
The system typically combines:
Smart meters to measure production and consumption.
Solar panels/batteries as distributed energy resources.
A trading platform to match buyers and sellers.
Dynamic pricing based on supply and demand.
Blockchain/distributed-ledger technology in some implementations for transaction records and settlement.
Utility/grid integration, because electricity still physically flows through the distribution grid even though the financial transaction is between peers.
Powerledger's xGrid can also support gifting electricity to friends, neighbors, schools, or community groups, and it has been deployed in projects involving utilities and energy communities.
Other technology worth considering
Energy Web is another major project in this space. Its current focus is broader—decentralized identity, data exchange, and coordination of distributed energy resources—rather than being simply a neighborhood electricity marketplace.
There are also academic/open-source approaches using blockchain + smart contracts + smart meters to create residential microgrid marketplaces. Research has demonstrated auction-based P2P trading in which households can buy and sell locally generated electricity.
If you're looking to actually deploy this
For a real neighborhood/community, I would evaluate Powerledger xGrid first. For a research project or prototype, a combination of smart meters + home energy management + a local market/auction algorithm + blockchain or another distributed ledger gives you more flexibility.
One important caveat: P2P trading doesn't necessarily mean your neighbor's electrons physically travel directly to your house. The distribution grid continues to manage the physical electricity flow; the P2P system primarily determines who gets credited/debited for locally generated energy. Regulatory rules and utility tariffs also determine whether a particular neighborhood can actually sell electricity directly to its neighbors.
