Power Ledger (POWR) is an Australian blockchain energy trading company and protocol, founded in 2016 by Dr. Jemma Green (co-founder, Chairwoman) and Dave Martin (co-founder/CEO) in Perth, Western Australia, that provides software infrastructure for peer-to-peer energy trading — specifically enabling owners of rooftop solar panels, small wind generators, and battery storage assets (collectively “prosumers”) to sell their surplus energy directly to specific buyers on the local electricity grid using blockchain settlement — without requiring the routing of value through the traditional utility company, using POWR as the platform access token and a secondary local-currency-pegged token (SPARKZ) as the energy payment unit, to create a dual-token model separating platform access costs from real-world energy billing fluctuations.

How It Works
- Dual-token model — Power Ledger operates two tokens: POWR (access, staking, governance; ERC-20 on Ethereum) and SPARKZ (energy payment unit, pegged to local fiat currency, representing 1:1 energy value in the trading market). Electricity buyers pay in SPARKZ; SPARKZ are obtained by converting POWR via the Power Ledger exchange ecosystem.
- Prosumer registration — Households and businesses with solar panels (or other DER — Distributed Energy Resources) register on the Power Ledger platform managed by a local utility (the “Application Host”). Smart meters connected to the grid measure actual energy generation and consumption.
- Energy offer posting — Solar prosumers set their sale price for excess electricity (within utility-allowed ranges). When their solar panels generate more than they consume, excess generation is logged in real time via smart meter IoT data.
- Matching and settlement — Power Ledger’s platform matches buyers and sellers in the local grid area. Settlement (payment of SPARKZ from buyer to prosumer) occurs on-chain at regular intervals (typically 30-minute energy distribution periods aligning with grid settlement windows).
- Grid integration — Energy still travels over the physical electricity grid (power distribution is not changed). What changes is the financial settlement layer — who gets paid for the electrons — which is handled by the blockchain platform rather than the utility company’s billing system.
- Carbon markets — Power Ledger has also developed EcoChain, a renewable energy certificate tracking product for carbon credit and renewable energy certificate (REC) markets.

Use Cases
- Peer-to-peer solar energy trading — Homeowners sell surplus solar energy to neighbors at better rates than the utility buyback feed-in tariff.
- Microgrids — Isolated communities (remote Australian towns, island microgrids) use Power Ledger to manage internal energy trading without grid connection.
- Shared solar — Community solar gardens where shared panel owners receive credits based on their ownership share without collocating with the panels.
- Renewable Energy Certificates (RECs) — EcoChain product tracks and trades RECs on blockchain for carbon markets and sustainability reporting.
- Electric Vehicle (EV) charging — P2P charging settlement for EV deployments where building owners monetize chargers.
History
- 2016 — Power Ledger founded in Perth, Western Australia by Dr. Jemma Green (academic researcher in distributed energy) and Dave Martin. First pilot projects conducted in the Perth area to prove the technical viability of blockchain energy settlement.
- 2017-09-15 — Power Ledger ICO raises approximately $34 million AUD in just 72 hours. The sale is one of Australia’s largest blockchain fundraises at the time. The project gains international attention.
- 2017-10 — Power Ledger wins the Richard Branson Extreme Tech Challenge, a global competition for innovative technology start-ups. Branson publicly endorses the project.
- 2018 — Power Ledger deploys pilots in multiple geographies: United States (Fremantle pilot), Thailand (BCPG energy company partnership for Bangkok microgrids), Japan (Kansai Electric Power Company partnership), and India (Uttar Pradesh grid trial).
- 2019 — Power Ledger begins working with the US-based company Clearway Energy and expands into community solar programs in the United States. Partnership with BCPG (Thailand) produces the first commercially operational P2P energy trading system in Southeast Asia.
- 2020–2021 — Power Ledger pivots toward institutional energy market clients and RECs/carbon market tracking products (EcoChain). The company refocuses from retail-only prosumer markets toward commercial and utility-scale deployments.
- 2022 — Power Ledger launches uPower, a retail energy platform built on the blockchain infrastructure for consumer-facing energy management.
- 2023 — Power Ledger reports commercial deployments across 12+ countries. The POWR token remains listed on major exchanges but the company operates increasingly as a B2B energy software vendor rather than a token-centric protocol.
- 2024 — Power Ledger continues operating as an active company. The gap between the token’s market presence and the company’s actual commercial traction in energy markets remains a communication challenge for the project.
Common Misconceptions
“Power Ledger delivers electricity directly between buyers and sellers.”
Physical electricity still travels over the existing power grid infrastructure — electrons don’t flow point-to-point between neighbors. What Power Ledger changes is the financial settlement and attribution: who gets credited/debited for the energy that travels over shared grid infrastructure.
“POWR is used to pay for electricity.”
SPARKZ is the energy payment token, pegged to local fiat. POWR is a platform access token and not spent directly on electricity purchases. This dual-token model separates speculative token price volatility from actual energy billing.
Social Media Sentiment
Power Ledger occupies an unusual position as a blockchain project that has genuine real-world pilots and commercial clients in regulated energy markets, but whose token (POWR) has significantly declined from 2018 ATH prices. The community sentiment is split: energy sector followers appreciate the genuine commercial deployments and award-winning technology, while crypto investors (many of whom bought near the 2018 peak) are dissatisfied with token price performance. The project is cited in academic and policy discussions about distributed energy resources and blockchain applications in regulated utility markets — a more legitimate long-term endorsement than token speculation.
