Major Actors. Part 4/5 in ‘Blockchain Powers Solar Industry’

Forbes has in June 2019 named the following five major actors in application of blockchain across the global solar industry.


WePower leaned upon the Estonia’s 100% digital energy grid. The firm partnered with an independent energy provider and offered consumers to buy into their program using WePower own utility tokens. At its platform, consumers can monitor energy prices and diversify their energy portfolio. Positive results in Estonia brought WePower to expansion into Australia.

Power Ledger

Australian Power Ledger helps develop the country’s renewable energy market whilst also offering cheaper prices locally. In the past decade, the number of personal solar power generation in Australian households exploded, and it is the core customer based to Power Ledger.

Power Ledger installed microgrids that connected clean energy producers and residential developments. Thus, on the blockchain based platform, that allows consumers and producers to monitor energy production, their sources and their prices, Power Ledger drives forward the sustainable development.

Power Ledger works in the UK, Thailand, and at home in Australia.

Acciona Energy & Iberdrola

Acciona Energy and Iberdrola are two Spain’s largest energy companies. They have both used the United Nations’ Sustainable Development Goals (SDG) as the framework for their clean energy program.

Acciona Energy became the first utility company to use blockchain technology to certify the origin of its energy to consumers whilst Iberdrola used a similar platform in its own pilot program. After good initial results, the latter has indicated that it intends to integrate the platform in future large scale projects whilst the former has continued to pioneer the use of blockchain within established energy markets.

The Brooklyn Microgrid

The Brooklyn Microgrid is a community-based approach to blockchain. It has transformed a traditional energy grid model into concept of a communal energy network. While the utility provider still maintains the electrical grid that delivers power, the actual energy is generated, stored, and traded locally by members of the community, for a more resilient and sustainable clean energy model.

Rather than use an independent utility company, community members will be able to contribute electricity via their own solar panels or electric cars to the microgrid for other residents to buy and trade. Any excess energy will be stored amongst members of the grid and will give the opportunity for Brooklyn consumers to be a step closer to being self-sufficient energy wise.

The Sun Exchange

The Sun Exchange is a startup that focuses on investment-driven solar installations. It identifies sun-soaked areas in South Africa where solar panels could be at their most efficient, then sells the modules to private investors who can then lease them to local schools and businesses. This business model ensures that local communities are able to benefit from cheap, clean energy whilst investors help fund and develop several projects that will generate income for the twenty years that solar panels are viable. All transactions can be processed bitcoin simplifying international monetary transactions, and the Sun Exchange uses blockchain-based smart contracts to reduce the needs and cost of physical administration.

The Sun Exchange acts as a crowdfunding platform for small- to medium-scale solar projects in developing countries, allowing investors worldwide to help fund plants with national currency or bitcoin payments. It has already funded projects including an 18-kilowatt rooftop solar plant for a Cape Town-based nonprofit and a 60-kilowatt system for an elephant park in Knysna, on South Africa’s south coast.
