Open source could make microgrids easier to plan, connect and adapt by sharing software, models, standards, data and some hardware designs. It is an opportunity to reduce specific development and coordination barriers—not a shortcut to guaranteed lower costs, reliability or scale. Real gains depend on compatible standards, capable implementation teams and local regulatory and utility conditions.
Why open source matters to microgrids
A microgrid brings together local generation, energy storage, loads and controls. Depending on its design, it can connect to a larger grid or operate independently as an island. Because each system must coordinate physical equipment and software, a project can involve more than choosing a controller: planners need to model resources and loads, engineers need to integrate devices, and operators need systems that work with utility infrastructure.

Open source is relevant across those layers. Shared tools can make planning and simulation more accessible; shared code and data can support development; common standards can help equipment exchange information; and open designs can contribute to education or hardware experimentation. Openness does not make different devices automatically compatible, but it can give teams a clearer starting point for examining how systems fit together.
In its June 2023 report, The Open Source Opportunity for Microgrids, Jessica Groopman and Jeff Lindstrom of Linux Foundation Research identified more than 20 open-source microgrid projects around the world and four standards developers that could be accessed at the time. Those are inventory counts from a sample landscape, not a comprehensive current census or a measure of market size.

Where the opportunity appears across the stack
The report’s landscape spans standards, education, modeling and simulation, software and platforms, foundations, and components or hardware. That breadth matters: shared code is only one part of the opportunity.
| Layer | Examples identified in the June 2023 report | Potential contribution |
|---|---|---|
| Standards and interoperability | OpenFMB; OpenADR | Common approaches can make it easier for systems and devices to exchange information and coordinate. |
| Modeling and simulation | GridLAB-D; OpenDSS | Models can help teams analyze grid and microgrid designs before implementation. The report describes GridLAB-D as open-source software for modeling and analyzing microgrids. |
| Software and platforms | Hyphae; Open Energy Microgrid Controller | Open software can provide a base for control and for distributing locally produced energy. |
| Components and hardware | Open Microgrid; Microgrid-in-a-Box | Open component designs can support experimentation, learning or modular system development; the report’s category does not establish that every design is ready for commercial deployment. |
These examples are not a ranked shortlist, and the report’s categories do not establish comparable deployment maturity, support or compatibility. A project’s fit depends on its function and evidence in the intended application.

Standards as a bridge between devices
The report describes OpenFMB as a reference architecture and framework for integrating distributed energy resources, including meters, relays, inverters and capacitor-bank controllers. It says the North American Energy Standards Board ratified OpenFMB in 2016. The approach uses common semantics and local data federation for control and reporting, including potential retrofits to legacy equipment. A framework can help define how information is represented and exchanged; it cannot by itself certify equipment or guarantee that a particular installation will interoperate.

DOE says PowerModelsONM evaluates candidate microgrid designs against resilience goals and predicted distribution-network threats, and can simulate recovery scenarios. DOE also reports software simulation and hardware-in-the-loop evaluation using utility-partner datasets. The software is described as available open source on GitHub, with a graphical interface through OMF. Tool features and access can change; check current project documentation and availability before selecting one.
Modularity in physical systems
DOE’s Microgrid Building Block concept connects power-conversion, communications, control and load modules to form a microgrid, with the possibility of connecting microgrids into larger systems. Common interfaces and modularity are intended to support plug-and-play operation and interoperability. This makes the physical architecture a useful complement to shared software: an open controller cannot make incompatible electrical equipment fit together, and a modular concept still requires system-level engineering.

What open source could improve
Linux Foundation Research grouped the potential value into five areas. They are plausible benefits, not results that follow automatically from publishing code or designs.
- Wider access to resources and education: Shared tools and learning materials may lower barriers for communities, researchers and smaller organizations that lack access to proprietary resources.
- Faster design and development: Reusable modules and shared data may reduce repeated work and help teams adapt existing approaches rather than start from scratch.
- Better interoperability: Common standards and semantics can help address the coordination problem between equipment, software and utility systems.
- More ways to provide services: Open tools can coexist with paid integration, customization, operations, training and maintenance.
- Resilience at broader scale: If designs and operating practices become easier to reuse, more communities may be able to plan systems suited to local resilience needs.
None of these possibilities establishes that open-source microgrids are already cheaper, more reliable or faster to deploy as a class. The reviewed sources do not establish a current, comparable market-size estimate specifically for open-source microgrids.

What still makes deployment difficult
The 2023 report identifies technical, institutional and market barriers. They help explain why shared software alone cannot resolve the harder parts of deployment.
- Fragmented standards and middleware: Gaps in standards, software interfaces and technical rules for power flows can leave components difficult to integrate. Low interoperability with utility systems or proprietary controls can also limit what a microgrid can do.
- Project-specific engineering: Designs vary with location, purpose, timing, devices and energy sources. Customization can increase engineering effort and makes shared interfaces and standards more important.
- Policy and utility incentives: The report describes policy and regulation that may favor centralized infrastructure, slow permitting, and utility incentives that may not reward customer investment in microgrids. These observations are context-dependent, especially in regulated U.S. utility markets, and should not be generalized to every jurisdiction.
- Skills and institutional capacity: Technical learning gaps and shortages of experienced people can constrain planning, integration and long-term operation.
- Incumbent and supply-chain constraints: Resistance from established interests and the availability of components—including batteries, semiconductors and solar panels—can affect whether projects move from design to deployment.
- Assurance and compatibility: Publicly inspectable code can support scrutiny, but openness alone does not provide security, reliability, certification or compatibility with proprietary equipment. Those require testing, governance and system-specific engineering.
How projects can create value without charging for the code
Open source does not mean the whole microgrid project is free. The Linux Foundation Research report describes business opportunities in the services and implementation work around shared tools and designs.
- Integration and ongoing management: A provider can configure equipment and software for a site, connect systems and maintain the installation.
- Energy-as-a-service: A provider may design, build, own, operate or maintain a system, potentially allowing a customer to avoid some upfront capital spending. The terms and allocation of risk depend on the contract.
- Retrofits and renewable upgrades: Existing backup systems may be upgraded or integrated with renewable resources, subject to technical and site constraints.
- Training and specialist support: Education, consulting, certification and customization can help organizations build the skills and processes needed to use shared tools.
- Utility-community partnerships: Collaboration can bring together local needs, utility systems and project expertise. Prosumer or peer-to-peer models are also possibilities identified by the report, not proof of a universally available market offer.
Public technical assistance is part of the implementation picture, too. DOE’s Community Microgrid Assistance Partnership supports communities seeking to build or optimize microgrids, including historically underserved and Indigenous communities in remote areas. In 2024, a six-month NREL and WRI Clean Energy to Communities peer-learning cohort involved 15 municipalities, municipal utilities, colleges and Tribes and addressed planning, design, procurement and funding for resilience projects. These examples show that institutional capacity and project preparation matter alongside software.

A project name or open license is not enough to establish suitability. Compare candidates against the job the system needs to perform and the conditions in which it will operate.
- Define the objective. Specify whether the need is planning, simulation, control, interoperability, education or a hardware design. State the resilience, energy-access or cost goal and the site conditions that matter.
- Check evidence and maturity. Look for documented deployments, validation methods, maintenance activity and clear project governance. Treat a sample landscape listing as evidence that a project was identified, not that it is production-ready.
- Map interfaces and equipment. Identify the relevant protocols, standards, devices and utility connections. Confirm compatibility with the intended equipment rather than assuming that open interfaces guarantee it.
- Review access and support. Examine the license, documentation, contributor community, training needs and available technical support. Plan for integration and maintenance even where the software itself is freely available.
- Test against local rules and operating needs. Evaluate permitting, utility requirements, safety and reliability expectations, and the availability of components and qualified personnel in the project’s jurisdiction.
- Plan a system-level validation path. Determine how the complete design—not just a software module—will be tested, secured, commissioned and maintained, including how it will behave during grid outages and restoration.
The strongest case for open source is therefore not “no-cost microgrids.” It is the possibility of reusable building blocks, shared knowledge and clearer interfaces, paired with the engineering, standards and local partnerships needed to make a particular system work.
