Project Update

This project was approved in October 2025. Initial activities included the project kick-off and finalizing subcontracts. In 2026 the project team will begin initial tasks of defining use-cases, control, and testing specifications within the existing microgrid; and begin software development and testing in simulation.

The Issue

Today’s microgrids typically operate building loads and some DER in isolation from each other. The microgrid controller often only manages the DERs, missing opportunities to coordinate them with the building loads. Currently, building automation system (BAS) are not responsive to grid signals, which limits their ability to optimize energy use in real-time. Furthermore, to compensate for energy needs during blackouts, microgrids often rely on fossil-fueled generators, which undermines efforts to reduce carbon emissions and improve sustainability.

Project Innovation

Leveraging recent advancements in advanced controls for buildings and DERs, this Agreement will develop and demonstrate an Integrated Microgrid and Building Orchestration and Optimization System. This technology aims to enhance the efficiency of building equipment and improve the resiliency of the microgrid, thereby reducing the reliance on backup generators and lowering carbon emissions. The innovation will enable the coordination of the microgrid and building systems under various modes of operation to sustain critical loads for as long as possible in islanded mode and to minimize emissions in grid-connected mode.

Project Goals

Demonstrating the ability of a new integrated microgrid and building orchestration to reduce cost and risk for operators

Evaluating how to scale up the technology and integrate it in the applicant’s commercial offer

Project Benefits

The expected benefits of this project include: 1) increased resiliency through the extension of the operation of the critical services during islanding; 2) reduced carbon footprint by minimizing energy use and reliance on fossil-fuel backup generators and grid power; 3) increased load flexibility by enabling optimal coordination of DERs to respond to grid signals; and 4) enhanced economic benefits for IE by reducing costs and lowering the company's financial risk. The proposed technology will also be demonstrated at a microgrid test facility and at the Viejas Enterprise microgrid site. Overall, the project will enhance IE technology and support the company's growth.
