Stop Burning Their Midnight
Oil with Large Scale Energy
How three remote communities
are now making efective use of
their abundant solar and wind energy
resources with the support of large scale
Li-ion Energy Storage Systems (ESSs).

Until recently, the world’s most remote off-grid communities have relied on traditional diesel generators to supply their
electricity needs. This has created signifcant cost and reliability issues. Sometimes, it can cost more to transport the
fuel to the site than it actually cost to purchase in the frst
place. Should adverse weather disrupt travel then there is a
risk of running out of fuel. Furthermore, the gensets need
regular expensive maintenance.
For these reasons a growing number of communities are
now turning to solar photovoltaics (PV) and wind turbines. And
in many cases, they are adopting microgrid solutions in which
the diesel generation and renewable plant complement each
other. The aim is always to ensure the reliability and autonomy
of the electricity supply and to optimize operating costs.
This is where a large scale lithium-ion (Li-ion) energy storage system (ESS) can play a vital role in mitigating the variable and unpredictable nature of wind and solar plants. The
ESS can perform a number of roles, including control of ramp
rates, power smoothing, power shaping, peak shaving and
