Equans Energy Solutions (EES) operates 28 CHP plants within the Netherlands and dedicated itself to the complex project on Oosterdok Eiland in Amsterdam. This involved the use of key figures for contracting future connections. With the planned completion in sight, it was necessary to check whether the calculations were sufficient. Erik-Jan supported EES in this task.

During the development of the Oosterdok Eiland, the engineering of the WKO plant used kentallen for the power to be contracted from future connections. As the planned completion of an additional lot with Booking.com and 42 homes in Q4 2022 approached, the need arose within EES for additional testing of the installed capacities (WTW, CHP and GKW) and a check whether future demand could be met.

Erik-Jan performed an analysis of EES data. From this it can be seen that capacities of tap water sets are set up cumulatively. This leads to high powers and over-dimensioning of the installation. Two calculations (Q√n method and MMV method) that take into account user behavior were performed to estimate the maximum drainable power. These calculations revealed a shortfall of 15kW of domestic hot water power after the expansion.

To estimate how the maximum off-take of CV and GKW power compares to the contracted power, Erik-Jan made a comparison between the total contracted power and the expected consumed power based on key figures. This analysis showed that the current power is sufficient in connecting the new consumers.
