Description of the Solutions
Limitations of the Solutions
|Automated Demand Response||Takes pressure off of the utility T&D grid during times of short capacity by making payments to the utility customer to curtail energy use but is not an effective solution for systematic, long term power outages.|
|Grid Power Supplemented by Diesel and/or UPS Batteries||Extremely expensive versus grid rate, can be used in most US cities only during systematic grid power outages and are notorious for poor starting capabilities. For some companies, they also contribute to a poor environmental image.|
|Grid Power Supplemented by More Efficient Boilers & Chillers||Does not provide any reliability benefits but higher efficiencies of new equipment saves on heating and cooling costs and carbon footprints. Market may be limited due to stricter boiler emissions regulations in some cities.|
|Grid Power Supplemented by CHP that Does Not Island to Provide Uninterrupted Power in Grid Outages||Results in significant energy cost savings and, for clients that can bear the risk of damages from power outages due to delayed islanding, can provide a superior and greener back-up option to diesels.|
|Grid Power Supplemented by CHP that Islands using a Synchronous Interconnection Approach||Utility approvals and custom engineering and controls to synchronize can be very expensive and take several years to complete but is the best current solution for customers that would incur high damages due to grid outages.|
Diesel backup systems have a history of failure in prolonged outages. Reliability increases dramatically with GridLink’s simultaneous access to both the existing utility grid and local power resources.
Fewer resources are used, since electricity no longer needs to transmit across vast distances. Supplemental grid power means fluctuating supply (i.e. sun, wind, etc.) is no longer a barrier to renewable energy sources.
GridLink enables DER owners to generate revenue from selling back excess power. Meanwhile, utilities gain access to lower-cost power sources. Everyone experiences better reliability.
With GridLink, distributed energy resources look like a load to utilities. By providing a level of abstraction, GridLink enables DER owners and utilities to add, remove, or change their power assets without concern for costly interconnection applications.
