Battery energy storage systems (BESS), when
co-located with a solar or wind farm, provide a more reliable
generation source by charging during periods of high irradiance or
high wind and discharging to meet demand during periods of low
irradiance or low wind.
Given this, we are seeing an increasing number of new solar and
wind projects incorporate a BESS component. Also, many owners of
existing wind and solar projects are seeking to 'retrofit'
their projects with a BESS.
While the technical challenges associated with a BESS retrofit
project are generally not considered to be materially more
problematic than installing a BESS at the 'greenfield'
stage, there are still a number of issues that an owner of an
existing solar or wind farm will need to carefully consider before
embarking on a BESS retrofit project.
