GridON sets the new standard for electrical grid reliability, safety, performance & efficiency

Commercial Fault Current Limiters for reliable connection of additional generation and distributed renewable energy sources to transmission and distribution networks

GridON enables the ever-growing demand for electricity consumption, while improving energy efficiency and network stability, and reducing carbon emissions. Fault currents, caused by short circuits in power grids, keep rising with the increase in electricity supply on meshed networks, and often exceed network protection capabilities. Cascading fault currents may result in supply disruptions, equipment damages and severe power outages. Grid operators are forced to invest hundreds of millions of dollars in order to prevent catastrophic consequences. Conventional solutions include grid segmentation and costly upgrades, which negatively impact power quality, stability and reliability of supply. 

GridON is offering grid operators and network designers fault current limiters (FCL) which enable network meshing and reliable connection of additional generation and renewable low carbon energy sources to transmission and distribution networks. FCLs reduce the overall resistance across meshed networks, hence reducing losses and offsetting millions of tonnes of carbon emissions. GridON's FCLs are also key retrofits for energy intensive industrial grids. The FCLs improve grid resilience and reliability, while eliminating network upgrades and early retirement of fit-for-use equipment, saving hundreds of millions of dollars in a typical grid.

GridON’s FCLs are in operation in live networks since early 2013, and the product has been commercially available since early 2014. GridON has been gaining interest from grid operators, power generation companies and energy-intensive industries, who are seeking energy efficiency solutions for the growing capacity challenges on their networks.

GridON’s variable-impedance FCL combines a novel electromagnetic alteration concept with conventional transformer technology. The self-triggered system responds instantaneously, suppresses the fault current for its entire duration, and recovers immediately following fault clearance; being always ready for consecutive faults. It is the first such fully tested, installed and commercially viable pre-saturated fault current limiter currently available in the market.
The breakthrough in design removes the need for superconducting components which results in a simple, extremely reliable and low maintenance solution. Unlike superconducting-based FCL technologies which have not reached commercial viability, GridON’s product is fully scalable for use at all power ratings in industrial, distribution and transmission grids. Specifically, GridON offers a cost-effective solution for the 80kA protection gear barrier on transmission networks.

GridON has partnered with Australian based Wilson Transformer Company – a shareholder and engineering and manufacturing partner - to bring this innovative state-of-the-art portfolio of FCL products to the market.
In June 2015, GridON was awarded the highly coveted Horizon 2020 grant from the European Commission, which has been used to develop an enhanced product line of Fault Current Limiters based on its long proven technology.
The new product line is very economical with significantly reduced footprint – targeting specifically distribution, industrial and independent power producing customers. 

GridON won prestigious awards including the 2013 UK Energy Innovation Award for the Best Energy Network Improvement, the 2012 European ACES Smart Grid and the 2011 GE ecomagination “Powering the Grid” award.
