The software development process has evolved from vendors owning, controlling, and selling proprietary software into a collaborative, open source model. The process of producing energy is going through a similar evolution.Consumers have become producers, generating and sharing sustainable solar, wind, and hydro energy, and open source software is part of that energy production evolution. In this article, I will introduce PowerMatcherSuite, a Flexiblepower Alliance Network project licensed under the Apache License, version 2.0.The suite is comprised of two disruptive open source technologies: the PowerMatcher and the Flexible Power Application Infrastructure (FPAI). Both technologies are complementary, but can also function on their own. The PowerMatcher is a smart grid coordination mechanism. FPAI is an operating system that enables appliances, the smart grid, and smart services to communicate with each other.
