The Xamax system collects and evaluates energy data at various measuring points within the senior citizens’ centres. The system detects load peaks and is capable of reducing them by temporarily shutting down specific electrical equipment. Alpiq identified major electricity consumers at both centres and integrated them into the optimisation system. The equipment eligible for inclusion comprised devices that can be switched off without having a noticeable impact on operations or jeopardising operational safety. These include food warmers, cooking vats, combination steamers, pressure cookers, dishwashers, washing machines, dryers and mangles.
The extent to which the load peaks and thus the grid costs can be reduced depends on the potential of switchable devices and systems. In some cases, it is possible to achieve a reduction of up to 30% in grid costs. However, reducing load peaks is not the only field of application. The state-of-the-art energy management system helps to achieve efficiency targets by identifying and monitoring measures to achieve an efficient use of electricity. More than 1,000 customers, including senior citizens' centres, hospitals, hotels, banks, insurance companies, foundries and metal finishers, rely on Xamax energy optimisation solutions.
Since 2015, the Rosengarten Centre in Laufen in the Swiss canton of Basel-Land has been operating an annex housing a specially designed unit for senior citizens suffering from dementia.
