GridNode Microgrid Solutions

Global energy trends of electrification, decarbonization, digitization, and decentralization are changing the current energy landscape. These trends combined with customer’s demand for solutions that provide increasing reliability, resiliency, sustainability, energy independence and energy cost reduction has led to the growing demand for microgrids.

GE’s GridNode Microgrid Solution provides real-time control and energy optimization that enables customers to obtain the maximum return on investment (ROI) from their systems.

The GridNode Microgrid Solution includes control and automation features such as operations management, transition management, dispatch control and energy optimization, operations planning, and market participation.

Customers Outcomes

  • Increased Reliability enhancements through real-time detection of unstable system behavior and isolation of the affected system ensuring your most critical infrastructure stays online until normal system operation is restored
  • Improved Resiliency by providing a system that can self-isolate from the affected grid and continue to support its loads independently for desired periods of time
  • Energy Cost Reduction through a solution that can efficiently manage and optimize your energy resources based on real-time energy market prices, operational costs and energy resource mix
  • Increased Revenue by enabling your system to provide ancillary services to the grid such as Frequency Control, Reserve Capacity, and Demand Response
  • Energy Security by effectively controlling, monitoring and optimizing your local energy assets reducing your need to rely on a centralized supply
  • Increased percentage of Renewables Integration through an energy management solution that supports the transition to new renewable energy targets and policies
  • Reduced Emissions from on-site generation sources through the optimal dispatch and management of your energy resource mix
  • Reduced Levelized Cost of Hydrogen (LCOH) through the optimization energy resources and advanced integration with the electrolyzers

What is a Microgrid

"A microgrid is a group of interconnected loads and distributed energy resources (DERs) with clearly defined electrical boundaries that acts as a single, controllable entity with respect to the grid. A microgrid can connect and disconnect from the grid to enable its operations in both grid-connected or islanded mode" – US DOE Microgrid Exchange Group, 2010

What is a microgrid

Why a Microgrid

Today’s energy trends of Decarbonization, Digitization, Decentralization, and Electrification are changing the energy landscape.
