Peak shaving for commercial kitchens

What is Flex-o-Mat?

Is it possible to find solutions to the lack of power and grid capacity by changing conventions in commercial kitchens? Yes, it seems so!   

In the Flex-o-Mat project, property owners and school kitchen companies are cooperating to investigate the un-explored potential for peak shaving in school kitchens. The project is carrying out measurements in school kitchens, including testing how a change in operating patterns and behavioural changes in the kitchens can reduce power peaks. In autumn 2022, the project will also investigate possible technical solutions for peak shaving.

Nya resultat från Flex-o-Mat!

I början av 2023 har vi analyserat mätdata från innan projektet startade och under projektet. Vi har till exempel undersökt hur energiförbrukningen och förekomsten av effekttoppar skiljer sig åt innan och under projektet när samma måltid lagas. Vi har också undersökt hur energiförbrukning och effekttoppar ser ut innan och under projektet under en vecka. Data från innan och efter det nya effekthanteringssystemet Sicotronic installerades har också undersökts.

Reduced power - good for everyone!

Did you know that it is possible to cook on reduced power through already existing functions on the ovens?

Measurement data from Flex-o-Mat

Today, effect data is collected from several school kitchens in the Uppsala region. The effect data is provided through Sveriges dataportal and at Energiportal Region Uppsala. To increase the awareness about power use in school kitchens a new application is tested in Tiunda School in Uppsala that later will be used in several other school kitchens. During the autumn, possible technical solutions are investigated. Effect measurements from school kitchens. The number of meals prepared by the kitchens is listed in each link.

Technology for peak shaving is being tested in three school kitchens in Uppsala

Kökspersonalen upplever ingen negativ påverkan på deras arbetsuppgifter i köket när systemet från Sicotronic används och kökspersonalen beskriver att dem inte märker att effekthanteringssystemet hanterar effekttoppar som uppkommer.

Why is peak shaving so important? 

Today, more electricity is used than ever before and with increased electrification in society, the demand for electricity is growing, which causes a lack of power and capacity in the electricity grid. The use of electricity often coincides at certain times of the day which causes power peaks that strains the electricity grid. If the power peaks were evened out, the capacity in the electricity grid would increase. Today, however, many businesses are lacking solutions that enable power equalization, for example in commercial kitchen businesses.  

By raising the question that concerns the lack of power and capacity in the electricity grid and spreading information and knowledge generated through this project, Flex-o-Mat aims to ensure that more businesses implement impact equalization in their work. The project also brings together commercial kitchen businesses, property owners and electrical consultants and enables collaboration on power issues.
