BSR shows the way: e-mobility as a flexible load to relieve the electricity market

As part of WindNODE, Berliner Stadtreinigung (BSR), the agency responsible for keeping Berlin clean, showed that a fleet of electric vehicles can act as a flexible load. In this way, BSR is not only optimising its electricity costs but is also helping to promote the expansion of the share of renewable energies in the electricity mix. Visitors can learn more via a high-resolution multi-touch monitor – but only when the current pandemic situation permits.

A major trend is that the share of renewable energies in the electricity mix is increasing all the time. However, wind and sun are not always available. Generation and consumption must be balanced so that electricity does not run out. If this is going to happen, the electricity market must become more flexible – so far, industrial units have primarily been used as a buffer to balance these aspects. However, another way to relieve the pressure on the electricity market is for an organisation to have a fleet of electric vehicles, as demonstrated by BSR in its initiative, which forms part of the WindNODE project run by the German Federal Ministry for Economic Affairs and Energy (BMWi).

Load management

In addition to the expansion of charging points, load management is particularly important in this regard. Load peaks can lead to high charging costs or even the power systems on the premises becoming overloaded. To minimise this, the flow of electricity at the charging points must be controlled. If the charging processes are then flexibly and cleverly distributed at different times of the day, other costs can be reduced and the pressure can be taken off the electricity market. NB: In this connection, the operational readiness of electric vehicles must always be ensured. BSR also addressed such issues as part of the WindNODE project.

BSR shows the way

In October 2020, BSR set up an information table in the canteen foyer of its head office at Ringbahnstraße 96 in Berlin's Tempelhof district, where interested parties can learn more about the optimisation of the energy industry, including networking with the electricity market, when the pandemic situation permits again. Here an interactive application helps to provide an understanding of the dependencies of the components in connection with this optimisation. However, other information, including about the electric vehicles and the charging stations, can also be called up on screen. In addition, other BSR topics could be added in the future.
