LF Energy Edge Interoperability and Flexibility is a special interest group advancing open source solutions for behind-the-meter energy coordination, flexibility management, and device-to-grid interoperability.
As energy systems become increasingly decentralized, the need for seamless coordination between behind-the-meter resources and the broader grid is growing rapidly. The LF Energy Edge Interoperability and Flexibility SIG brings together utilities, vendors, researchers, and open source developers to collaborate on technologies that enable interoperable, secure, and flexible energy operations at the grid edge. The group supports and aligns LF Energy projects focused on home and building energy management, device interoperability, EV charging, and distributed energy resource integration. Through shared standards, reusable software components, and cross-project collaboration, the SIG aims to accelerate the adoption of open, vendor-agnostic solutions that unlock greater system flexibility, empower consumers, and strengthen overall grid resilience.
The projects currently included in this SIG are:
- EVerest: EVerest is a versatile open source charging station software stack, designed for both private and public charging stations. Built on a modular microservice architecture, it supports a broad range of industry protocols, including OCPP, ISO15118, IEC 61851, and others.
- CitrineOS: CitrineOS is an open source Charge Point Management System (CPMS) for OCPP 2.0.1, designed to support the transition from legacy OCPP 1.6 implementations. Key features include support for Core, Advanced Security, UI, and Device Management capabilities of OCPP 2.0.1; OCPI 2.2.1 integration for roaming; interoperability tools for testing and building OCPP 2.0.1-compliant systems; and more.
- FlexMeasures: FlexMeasures is the intelligent and developer-friendly EMS to support real-time energy flexibility apps, rapidly and scalable.
- Hyphae: With energy resources and infrastructure increasingly challenged to meet the coming impacts of climate change and natural disasters, Hyphae aims to make the grid more resilient and flexible with microgrids.
- ORES: ORES (Open Renewable Energy Systems) is an open source initiative under LF Energy focused on accelerating the development and adoption of interoperable, modular, and intelligent energy systems.
- OpenLEADR: OpenLEADR provides free and open source implementations of the Open Automated Demand Response (OpenADR) protocol – an industry standard for enabling energy flexibility across grids, devices, and services.
