Second life battery energy storage systems can help to increase the self-consumption of electricity produced from solar PV or wind turbine assets, thus increasing the degree of self-sufficiency and ultimately the economic viability of renewable energy systems.

A load peak is a very high demand for electricity for a short period of time, which determines part of the electricity price to be paid. Second life battery energy storage systems can reduce these electricity costs by providing the required electricity from the battery energy storage system rather than drawing it from the public power grid.

In the event of unplanned, short-term power failures, second life battery energy storage systems ensure that electrical components are constantly supplied with power.

Second life battery energy storage systems are used to stabilize the grid when there is too much or too little electricity being fed into the grid at short notice. They can also help to prevent local grid bottlenecks and thus avoid expensive grid expansion investments.

Electric vehicle charging points combined with second life battery energy storage systems ensure that several electric vehicles can be charged in parallel without overloading the local power grid.
