The challenges of zero emission construction sites.
Grid congestion in urban areas is a growing concern for construction companies as the demand for electricity continues to increase. As it becomes more problematic to get a large grid connection, construction companies find themselves in a squeeze to meet their power needs, causing project delays or failure to adhere to sustainability goals.
Due to the limitations of the use of fossil fuel powered gensets in urban areas, the demand for electricity continues to increase and the limited capacity of the distribution network in densely populated areas will become an even bigger constraint. Not acting upon this means project delays and added costs, causing projects to fail to complete on time.
Construction companies that do take action to tackle this problem will be better equipped to meet the challenges of grid congestion. These companies will look into opportunities to do ‘more with less’, by finding alternative solutions for temporary power and exploring ways to increase energy efficiency.
QuinteQ Energy can play a role in providing this energy flexibility by addressing grid congestion and helping construction companies to do more with less.
Fitting tower cranes in small grid connections with flywheels
QuinteQ’s flywheel energy storage system offers an efficient solution to grid congestion. The flywheel can be used to smooth out high power peaks, known as peak shaving, allowing construction sites to run on smaller grid connections.
Although several chemical batteries are entering this market, we strongly believe that construction sites with large tower cranes need a solution with a fast response, endless cycles and no extra fire hazard. The intensive interval of heavy power peaks caused by tower cranes puts severe stress on chemical cells (such as lithium-ion), causing their life-time to significantly decrease. In contrast, our mechanical battery can deliver near endless power peaks.
Our containerized flywheel solution is built to last (>30 years operation possible) and requires almost no maintenance, making it an attractive solution for operational lease. Not only that, but our machines are fully recyclable. Combining this design aspect with the fact that no harmful materials are used, we know that our flywheel offers the most sustainable solution on the market.
Don’t let grid congestion hold you back, take control with QuinteQ’s flywheel energy storage system.
