A better way to integrate distributed energy resources and the grid.

GridLink

As the technical platform for our two-sided business model, GridLink is a patented configuration of off-the-shelf components. At its core, GridLink relies on power electronics built, tested, and installed by General Electric (“GE”) at numerous sites around the world.

While GridLink boasts a variety of capabilities, three primary benefits have piqued the interest of utilities (DNOs) and transmission network operators (TNOs) as well as DG owners: 1) protecting the macrogrid from the microgrid (eliminating fault current contributions); 2) allowing the microgrid to maintain power seamlessly during a macrogrid outage (i.e. ride through faults from the macrogrid); and 3) qualifying the microgrid as a least-cost option for the DNO/TNO to maintain grid stability (e.g. voltage/frequency control). At a cost of less than half of competitive synchronous options, GridLink represents the least-cost solution to an increasingly important set of energy problems. Third party studies, including an IEEE peer-reviewed journal article, have verified the superior functionality and cost-benefit value of GridLink’s non-synchronous interconnection platform.

Inside of GridLink, power electronics with back-to-back AC-to-DC-to-AC converters enable the voltage, frequency, and phase angle of the utility grid and the on-site generators to be completely isolated from one another. Therefore, to the utility, the microgrid looks like a single inverter. From the perspective of the utility companies, power is distributed exactly as it was when the customers were using the utility grid alone. However if an outage occurs, the grid can tap into the distributed generation (DG) as back-up power sources. Meanwhile, DG and microgrid owners can now dynamically and efficiently draw from both the existing grid as well as their on-site power sources. And since a microgrid with GridLink looks to the utility grid like a load and not generation, no interconnection application is required. In essence, GridLink provides a level of abstraction that allows both the utilities and microgrid owners to have the design flexibility to add and maintain their assets without concern for ripple effects to the other party.

GridLink: the Distribution System Platform

Learn More about the Tech

  • Reliability

    Reliability increases dramatically with GridLink’s simultaneous access to both the existing utility grid and local power resources. For the utility grid, GridLink opens the door to additional pathways and sources of generation -- that type of flexibility can be a game changer when responding to outages.

  • Sustainability

    With distributed energy resources (DER), supply is co-located with demand, meaning fewer resources are used transporting and distributing electricity across vast distances. For DER sites relying on renewable energy, GridLink enables the grid to provide supplemental electricity. Intermittency of natural resources (i.e. sun, wind, etc.) is no longer a barrier to green energy.

  • Economic Advantage

    GridLink enables DER owners to generate revenue from selling back excess power at improved rates (better than wholesale). Meanwhile, utilities gain access to lower-cost power sources and the ability to sell ancillary services into grid regulation markets. Win-win.

  • Efficiency

    With GridLink's non-synchronous approach, distributed generators run 15-20% more efficiently since they do not need to match the frequency of the utility grid.

  • Quality

    Ever heard that garbage in equals garbage out? We beg to differ. GridLink's non-synchronous approach conditions the power, eliminating voltage sags and spikes, harmonics, and transients. GridLink leaves the electricity better than it found it.
