Rolls-Royce supplies battery containers to balance Singapore’s power grid

Rolls-Royce has supplied three mtu EnergyPacks to system integrator Eigen Energy in Singapore to integrate more renewable energy and offset peak electricity loads on the power grid.
The compact battery containers, which will support the ultra-fast-charge EVs at three Shell service stations, feed the remaining electricity into the public power grid during periods of low use.
A consortium around Eigen Energy and Rolls-Royce’s business unit Power Systems designed and built the battery storage units to meet special safety precautions due to their proximity to the refuelling station within the city.
The e-filling stations each have a power capability of 180KW and are the fastest publicly available at service stations in Singapore, states Rolls Royce in a release.
With the help of the battery containers, electricity from photovoltaic (PV) systems is integrated into the energy system, which will also serve to offset peak electricity loads.

In announcing the battery pack supply, Rolls Royce states the potential of e-mobility to cause local grid constraints: if several vehicles charge in parallel at a fast-charging point, the demand for electrical energy increases rapidly and at short notice.
Using an advanced control system, the mtu EnergetIQ, mtu battery storage systems can help prevent temporary load peaks with the corresponding high electricity costs.
According to the manufacturer, the control system recognises when the energy is needed for charging or when it can be fed into the grid, and also manages the influx of power from regenerative energies such as PV.
Rolls-Royce has already supplied mtu EnergyPacks for around ten e-charging projects globally.
This includes energy company Verbund in Austria, Stadtwerke Münster, which uses them to power its e-bus fleet and project development company Abowind.
