Power Ledger (POWR) is an Australian company facilitating electricity and environmental commodity trading through blockchain technology. Power Ledger's platforms and products are focused on peer-to-peer energy trading, and includes the ability for the decentralized selling and buying of renewable energy. Power Ledger's scalable platform provides qualified consumers with access to a variety of energy markets, and has been integrated with various energy infrastructures and regulations, worldwide. Dr. Jemma Green, co-founder and chairman of Power Ledger described the company as "a technology company that facilitates peer-to-peer trading of electricity, so everyday people that have got solar panels can trade electricity with their neighbours". 
Founded in 2016, Power Ledger was Australia's first cryptocurrency raising  in which they raised $17 million and received criticism for allegedly using "bounty hunters" after their ICO funding model finished in 2017. AUD. In response to criticism surrounding their funding, during a 2020 Select Committee on Financial Technology and Regulatory Technology,  Dr Jemma Green asked that more consideration be given to allowing ICOs to operate in Australia, stating "that Australian entrepreneurs are really suffering from a lack of access to venture capital". 
Power Ledger has received support from those in Environmental Sciences  for their approach to decentralizing energy trading, and has found support in State Government, where on July 2nd, 2020, Western Australia's Governor, Kim Beazley, visited two sites at which Power Ledger's block-chain technology was in use - the White Gum Valley Project – three different apartment buildings, all with solar and battery systems, and the East Village Project – a 670kw hour battery which allows 36 homes to trade with each other via the battery. In his stated reflections, the Governor stated Today I saw the future. It is such a lucky thing that an organisation like Power Ledger should be founded here. To be able to look at how the whole system works, which I think I understand about 20 percent of, is a privilege.. 
Plans for a blockchain energy trading platform based in Perth, Australia were publicly announced on 11 August 2016 by chair Dr. Jemma Green and managing director Dave Martin. On 24 August the company announced that it would utilize Ecochain technology to store energy readings. Power Ledger's white paper was officially released in a company press release on 27 July 2017. In the white paper, the company revealed an ERC-20 Ethereum-based token called POWR, which would be implemented into the Power Ledger platform, and Sparkz, on their own Consortium Ethereum Network. The company maintained that demand for POWR tokens would increase as the platform user-base grows, thereby changing the price of the token and allowing for the exchange of POWR tokens for Sparkz tokens.
In October 2017, Australian Energy company, Origin Energy performed a three month technical trial with Power Ledger in which they simulated a market based on their customer data.  - Origin Energy subsequently decided not to proceed further.
The company paid spruikers to pump the price of the token in 2018. 
The company launched its pre-sale on 27 August 2017. In three days, over 100 million POWR tokens were sold, with 25% sold in the first hour. An extra 5% of tokens was awarded to every transaction that took place during the pre-sale. Power Ledger raised $17 million AUD during its pre-sale, which ended on 3 September 2017.
Public sale of POWR tokens officially began on 6 October 2017, during the company's initial coin offering (ICO). An additional 150 million POWR tokens were offered during the main sale. On 6 October 2017 the company had reported that it had raised over $34 million AUD ($24 million USD) overall during its ICO, including the amount raised during the pre-sale. A reported 15,000 supporters backed the token.
On 17 November 2017 the company announced in a press release  that the Australian government had awarded $2.57 million AUD in grants for a two-year research project to take place in the City of Fremantle. The project is expected to be Power Ledger's first examination of the potential of blockchain technology in integrating distributed energy and water systems. Seven additional project partners contributed a combined value of $5.68 million for the project for a total funding of $8 million. The project was the second-largest recipient of the 2017 Smart Cities and Suburbs Program award, a $50 million grant from the Australian government supporting innovative smart city projects.
Peer-to-Peer Trading Platform
The platform's trading market is based on a dual-token ecosystem operating on two blockchain layers: POWR and Sparkz. POWR tokens allow consumers and hosts providing energy to interface with the ecosystem and are protected through Smart Bond technology. POWR tokens can be converted into Sparkz tokens, which can be used for frictionless transactions in the energy exchange market. The initial coin offering for POWR tokens became the largest crowdfunding project in Australia and the 14th highest in the world.
The platform also allows users to gift their generated power to others, such as their parents, children, a local school, or charity.
